T A RECENT Captains of Construction leadership forum in Sandton, Johannes Musel, CEO of Hitachi Power Africa, noted that critical skills that had been transferred by multinational companies to workers at Eskom’s delayed new power stations stand to be lost, should no new projects follow timeously. This is an excellent point, and one that, in my opinion, points in the direction of both the public and the private sectors in South Africa.

Recently speaking to visiting European representatives of several construction vehicle and equipment manufacturers, with long-established presences in South Africa, I was interested to discover their thoughts on what was holding back development of the infrastructure sector.

Several cited wasted opportunities for skills transfer on a sustainable basis. As an example, one representative found it very confusing to witness machine operators being fired instead of being provided with opportunities to learn from their mistakes – the more so, since he found their initial training to be so inadequate. From a purely pragmatic point of view, he found this ludicrous, as damage to machinery, reduction of machinery- and plant-life, downtime, and inefficiencies on-site come at a very high price to both the companies involved and the economy as a whole. With Marikana back in the news, the release of increasingly poorer unemployment data, and tensions growing around increasing challenges South Africa is facing, there is definitely one thing we all do have control over, and that is how we treat each other.

We can teach, not criticise; we can support, not enable; we can encourage, not threaten; and we can all remember to be on the lookout for each other’s strengths, rather than weaknesses.

I had the good fortune to attend African Utility Week in May, and what a week it was. Delegates were spoiled for choice on both the conference and the exhibition side, and the Industry Awards delivered some seriously good news about some wonderful achievements, the highlight being City Power’s MD, Sicelo Goodwill Xulu, taking the

IMESA and 3S Media sign historic contract renewal Cape Town was also the setting for a rather historic moment between the Institute of Municipal Engineering Southern Africa (IMESA) and 3S Media, when IMESA president Duncan Daries and 3S Media managing director and publisher Elizabeth Shorten signed the contract that will see the continuation of a publishing partnership that began in 1975 and that has gone from strength to strength. IMIESA is a true leader in its field, covering a unique segment of the South Africa’s developmental and economic trajectory that is fundamental to the well-being of the nation. “3S Media is extremely proud of its partnership with IMESA and it means a great deal to me personally as well,” says Shorten.

“My father first approached the institute in 1975 with the proposal to publish a monthly title, and IMIESA was the result.

“To be signing a renewal contract 40 years later, in a much-changed country, in a much-changed world, is a wonderful reminder of the passion with which my father built the title and how IMIESA continues – through the written word – to contribute to the growth of South Africa,” concludes Shorten.

PRESIDENT’S COMMENT

IMESA

Metal theft Duncan Daries, IMESA president

Metal, and especially copper cable, theft has cost the country in the order of R5 billion (Salga’s estimate) per annum, over the last few years. This phenomenon has been fuelled by the insatiable scrap metal consumption of China and India.

I

N CAPE TOWN, it is estimated that 70% of thieves involved in this activity are drug addicts who steal in order to support their dependencies. However, these thieves are organised by unscrupulous owners or employees of scrap metal dealers and crime syndicates, who expor t directly, bypassing the scrapyard.

The resultant disruption to service delivery (electricity outages, water supply down, industr y productivity stalled, train commuters late, etc.), as well as increased public liability claims (missing manhole covers causing injuries and vehicle damages), has been branded as economic sabotage by the Minister of CoGTA, Pravin Gordhan.

Other than catching thieves in the act of stealing cable or metal covers, prosecutions of scrap metal dealers in possession of illegally obtained cable are difficult, as the identification of the owner proves problematic.

The City of Cape Town, in 2007, spearheaded an approach

by forming a specialised law enforcement unit dedicated to combating the scourge of nonferrous metal theft. This unit, known as the ‘Copperheads’, was hugely successful and, in its first year of operation, was responsible for reducing the estimated metal theft cost from R22 million to R500 000 per annum.

Through these efforts, many lessons were learnt, and discussions took place at a national level to identify the stumbling blocks in the crime fighting and judicial systems hindering effective action against this criminal activity. The following significant measures have, thus far, been put in place: • The passing of the SecondHand Goods Act, which makes the buyer of stolen goods as guilty as the person who stole the goods.

• A training manual for SAPS, developed in conjunction with Sarpa (South African Revenue Protection Association), which focuses on the trading in second-hand goods and combating the illegal trade in

non-ferrous metal, has been rolled out country-wide. This gives direction to the evidence collection process, to ensure successful prosecution of metal theft cases.

• SAPS taking over the responsibility of coordinating the NFMCCC (Non-Ferrous Metal Crime Combating Committee, which consists of representatives of public entities and private businesses) and conducting regular meetings, even at station level.

This improves the sharing of knowledge, the identification of crime syndicates, and the effective prosecution process.

• Technological developments have focused on the identification copper cables and warning systems when breaks in telecommunication and power conduits are detected.

• CoGTA’s elevation of metal theft as a priority issue, making it part of its ‘back to basics’ campaign with municipalities.

IMESA fully endorses these effor ts and suppor ts any

inter ventions that enhance service delivery and redirect this unnecessary expenditure toward the provision or renewal of infrastructure, where it is most needed.

Engineering efforts to stem this tide have concentrated on the use of alternative materials, which have a reduced, or no, scrap value. In the case of manhole covers, the industry has, over the past few years, introduced reinforced concrete, reinforced fibre cement, ductile steel, polywood, and combinations of these materials. These materials have, however, not been able to replace the intrinsic properties of the cast iron being replaced i.e. weight, durability, stability, tensile, and compressive strength. The same is probably true in the cable industry as well, where the properties of alternate materials do not match the copper.

It is, therefore, imperative that all efforts need to be directed at curtailing metal theft as a whole, as it is a threat to sustainable infrastructure provision and, subsequently, service delivery.

COVER STORY

Creating the Rustenburg

Rapid Transport system North West civil engineering contractor M Civils is expanding its core focus in road construction, diversifying into residential building and allied services, as well as niche load and haul services in contract mining.

O

NCE COMPLETED, THE Rustenburg Rapid Transport (RRT) system will serve an 18 km trunk line network of dedicated bus lanes and station terminals, with local contractor M Civils forging ahead with key phases of the construction programme.

The RRT forms part of the 2025 Rustenburg City Development strategy that is set to transform the city and the way it interconnects with the neighbouring mining and agricultural communities it serves. Similar to other bus rapid transport (BRT) initiatives constructed in Johannesburg and Cape Town (referred to under their project names of Rea Vaya and MyCiTi, respectively), the first phases of the RRT are due to come on stream during 2016, via trunk corridors, direct routes, and feeder services. Some 80% of the Rustenburg Local Municipality will be covered once the RRT system is completed, catering for upwards of 200 000 commuters.

M Civils completed the first phase of the RRT contract in January 2014, which was valued at around R412 million, and extended over a project duration of around 18 months. The scope of works here entailed construction of 5 km of RTT section, which comprised the upgrading of the north- and southbound sections to a dual carriageway, the installation of a dedicated central concrete lane for the buses, as well as the foundations for the bus stations.

IMIESA June 2015

Thereafter, in May 2014, M Civils was awarded three of the four contracts (namely A, C, and D work packages) for the second phase of the RRT, with a combined value of around R798 million. Stage A has been finalised and the balance is due for completion in April 2017.

A track record of excellence Headed by managing director Mike de Kock, M Civils is an 8CE PE contractor, according to the Construction Industry Development Board (cidb), and the company has a well-respected track record for both private and public sector road and infrastructure developments that serve as key socio-economic conduits in the North West, famed globally for its rich platinum and allied metals industries.

To date, more than 120 contracts have been completed, since the company’s formation in 1997, for a range of civil engineering projects that include bulk earthworks establishment for blue-chip mining houses, township services (sewer, bulk water reticulation, and stormwater control systems), and pavement rehabilitation. Milestone civil services projects include 45 km of internal sewers for Tekwane village close to Bleskop.

Supporting all these initiatives is M Civils’ expanding, mixed earthmoving fleet, now numbering more than 100 units. This fleet includes Caterpillar machines such as Cat 140K motor graders, Cat 428F backhoe loaders,

COVER STORY

and Cat 320D L hydraulic excavators, supplied and supported by Southern African Cat dealer Barloworld Equipment. Cat graders remain the preferred choice for M Civils for building-site work and road construction.

“For any civil engineering contractor, optimal grading performance is essential and we regard the Cat 140K as the industry benchmark,” says M Civils contract manager Richard Stone. “This has been reinforced time and again on our road and infrastructure projects.”

Past milestone contracts include the construction of the Leeuwkop shaft terrace for Impala Platinum’s Afplats. A challenging contract, M Civils was tasked with blasting and excavating some 190 000 m3 of unsuitable material from the terrace area, and importing 170 000 m3 of dump rock and norite over a 17 ha site.

Another complex project entailed the construction of a ring road in Phokeng for the Rustenburg Local Municipality. This fasttracked contract involved the construction of approximately 3 km of a four-lane carriageway, two large culvert crossings, and the upgrading of around 8 km of existing road.

M Civils has also played its part in South Africa’s highly successful hosting of the 2010 FIFA World Cup. The scope here, for the Royal Bafokeng Sports Trust, saw the construction of a bulk water pipeline supplying potable water to the five-star hotel at the Bafokeng Sports Campus, which housed the English national team during the tournament.

Meanwhile, in 2011/2012, M Civils converted a series of internal gravel road networks to asphalt, surfacing with a 25 mm premix, in the Rustenburg townships of Boitekong and Lethabong. Work also included stormwater accommodation.

M Civils continues to roll out similar projects, on an ongoing basis, across the North West and the company’s fast-tracking capabilities form part of the solution. For example, tasked with an emergency repair contract for the North West Department of Public Works, Roads and Transport – on the Mafikeng to Vryburg section – M Civils completed a scheduled six-month project in around 60 days, in February 2012, along a 6 km to 8 km section.

A diversified strategy On these and other projects, community upliftment and skills transfer are central to all M Civils contracts, especially on labour-intensive components, where the training focus includes pothole repairs and concrete block paving.

ABOVE From left to right: Barloworld Equipment Cat sales professional Molly Breton and M Civils site agent Reino de Kock OPPOSITE An aerial perspective showing a section of the Rustenburg Rapid Transport system at an advanced stage of construction

Addressing the current skills shortage in building and construction, plans are now underway at M Civils to open its own training centre, initially for internal requirements, and later for the outside commercial market. M Civils also plays its part in facilitating SMME development, managing and mentoring subcontractors across all its projects.

Maintaining its civil engineering focus, the company has recently diversified into new industry sectors that include turnkey services for the construction of affordable housing

by Impala Platinum for its employees, while further building activities include work for the South African Department of Human Settlements in Klerksdorp, where close to 500 RDP homes have undergone structural repair work by M Civils, following the earthquake that occurred in the region in August 2014.

M Civils teams are now employed from May 2015 in the servicing and sale of approximately 4 500 stands in Bokamoso, which is situated approximately 10 km from Rustenburg.

This is a joint project between Anglo American

“For any civil engineering contractor, optimal grading performance is essential and we regard the Cat 140K as the industry benchmark.” Richard Stone, contract manager, M Civils developments, as well as a venture into mine tailings load and haul contracting.

Towards the end of 2012, M Civils was awarded a contract from Anglo Platinum to construct 310 fully serviced stands in Northam Extension 6, as well as individual free-standing homes, for mine personnel, with the final phases completed during 2015. M Civils was also responsible for the marketing and sale of these homes.

Other work completed includes internal works and infrastructure development for Platinum Village – a housing project commissioned

Platinum, the Rustenburg Local Municipality, the Department of Human Settlements, and North West provincial government. In the first phase, M Civils will construct and market some 1 600 homes over an estimated period of 24 months.

“M Civils has a strong order book going forward, which supports our diversified strategy, and we anticipate excellent growth, over the next 12 months, through new contract opportunities across the North West. This could translate to work worth over R1 billion,” adds Stone.

ing Africa’s infrastructure to climate change outweigh the costs

Standard gauge railway to boost local steel firms China Bridge and Road Corporation (CRBC) is in the process of buying over 5 000 tonnes of steel, worth more than $3.7 million, from Kenyan manufacturers for the construction of a standard gauge railway (SGR).

This will be the first largescale local purchase of steel by the CRBC since construction of the new railway began. The firm previously purchased smaller consignments from different Kenyan steelmakers.

“We have tested the suppliers’ steel products that are participating in this process in our SGR project centre lab and they have met the requirements for the project,” says James Chen, CRBC business manager.

The firm said the 5 250 tonnes of steel bars are expected to meet the requirements for the construction of culverts and bridge foundations for about three months.

The impact of climate change on Africa’s water and energy infrastructure will be costly, according to a new World Bank report, and immediate action is needed to reduce these risks.

The report uses, for the first time, a consistent approach across river basins and power systems in Africa, and a wide range of state-of-the-art climate projections to evaluate the risks posed by climate change to planned investments in Africa’s water and power sectors.

While ignoring climate change could result in planning and designing infrastructure unsuitable for future climates, the study points to a risk of adapting to climate change in the wrong way, which could have significant implications.

The report provides actionable steps to increase resilience in Africa’s infrastructure, including providing technical guidelines on integrating climate change into the planning and design of infrastructure.

BOTSWANA Industry-oriented training important Botswana’s government is not doing enough to train people with relevant skills that can grow the economy, the managing director of Allied Engineering Services, Emmanuel Paradza, has said.

He was speaking during a breakfast meeting, held by the Minister of Trade and Industry, to discuss issues that were of particular interest to both the government and private sector in

The increase in construction activities in Botswana will boost economic development

terms of growing the economy and creating employment.

Paradza urged the government to provide apprenticeship training that is relevant for the engineering industry. He said economic development that had led to growth in jobs was as a result of business-oriented services and the increase in construction activities.

He added that more construction brought higher demand for engineering, architecture, surveying, landscaping, and horticultural services.

NAMIBIA Major infrastructure upgrades for Erongo Erongo will see the upgrading of key infrastructure over the next three years. The infrastructure projects will be partly funded through the government’s Medium-Term Expenditure Framework (MTEF).

The value of the MTEF development projects to be funded, 1 April 2015 to 31 March 2018, amounts to N$36.8 billion, of which 7% (N$2.6 billion) is earmarked for projects in Erongo, which represents the third largest allocation of all regions.

Some of the largest projects planned for Erongo include a

new road between Swakopmund and Walvis Bay (N$1.3 billion), the Karibib-Usakos-Swakopmund road upgrade (N$747 million), farm land purchases for land reform (N$592 million), the Walvis Bay airport upgrade (N$447 million), and the Namibian navy headquarters in Walvis Bay (N$396 million).

RWANDA New bidding procedure for construction jobs Effective next financial year, which begins in July, construction firms will be required to bid for public works according to newly established categories.

Officials at the Rwanda Public Procurement Authority (RPPA) say they are in the process of putting all construction firms in categories depending on their financial, logistical, and human resource capacities.

The move, according to RPPA director general Augustus Seminega, aims at streamlining operations, eliminating unfair competition, and reducing the possibilities of corruption and breach of contract, among other ills. There will be six categories, from A to F, he says.

According to the categories, companies can only go for tenders that fall in their category and two categories below it. A non-categorised foreign company will be awarded a tender only once and must then be categorised for another.

“We shall be revising the categories annually, making it possible for a company to move to an upper or lower category,

depending on their capacity at a given period of time," Seminega says.

TANZANIA $596 million Dar es Salaam port upgrade works begin Civil works have started on the $596 million upgrade of Dar es Salaam port, involving financing by both bilateral and multilateral donors and overseen by nonprofit consultancy TradeMark East Africa (TMEA).

According to Philippe Dongier, World Bank country director for Tanzania, Uganda and Burundi, the event is happening at the right time, when the World Bank, together with the Tanzanian government, the British Department of International Development (DFID), and TMEA, is preparing a substantive programme to increase the capacity and efficiency of the port.

Port capacity will double to 28 million tonnes by 2020. Dongier said the total cost is envisaged to be $596 million, including an IBRD Enclave loan of up to $400 million – the first of its kind in the Africa region – a prospective grant of $136 million from DFID, and committed and pipeline support from TMEA to the sum of $60 million, excluding the complementary private investment in the port.

Modernising and expanding the Dar es Salaam port will reduce ships’ dwell time from nine to ten days, down to just five days by 2020.

Much more than

whale watching

Overstrand Local Municipality, located on the west coast of South Africa and incorporating Hermanus, Kleinmond, Gansbaai, and Stanford, is a sterling example of local governance. Famous for its whale watching, the municipality has infrastructure projects in progress that demonstrate its efficiency. BY BEATRIX KNOPJES

ASED ON AN investigation into the water resources for De Kelders by Overstrand Local Municipality, the water supplied from the various fountains in and around De Kelders was classified as varying from ‘slightly brackish’ to ‘moderately brackish’, and ‘hard’ to ‘very hard’, resulting in scaling of calcium carbonates in the hot water cylinders and kettles of the residents. Historically, water supplied from these two fountains was only disinfected and then pumped directly into the De Kelders and Gansbaai water distribution systems.

De Kelders reverse osmosis water treatment plant During 2010, the municipality initiated a project for the implementation of a new water treatment works (WTW) for De Kelders, to treat the water supplied from the Klipgat and Grotte fountains to SANS 0241 standards.

Construction of the new water treatment works commenced in June 2011, and was completed in May 2012. The water treatment processes comprise both ultrafiltration (UF) and reverse osmosis (RO) technologies, which are advanced and proven treatment technologies. The use of this treatment technology enables minimisation of the footprint of the treatment works, the impact on the environment, and also water losses associated with the process.

IMIESA June 2015

Water is blended from the two fountains at the De Kelders WTW. An iron oxidation step was introduced at the intake of the raw water buffer tank using an aeration technique. From the raw water buffer tanks, the water passes through a strainer and is then pumped to the UF process. The UF filtered water is subsequently treated with a two-stage brackish water RO process. Partial blending of the RO permeate and UF filtrate is done, followed by a disinfection step, before the water is transferred to the De Kelders reservoir.

All valves and pumps are controlled by the MasterLogic Programmable Logic Control (PLC). The flow rate is monitored at the feed flow meter and variable speed drive (VSD) controlled feed pump. The filtrate pressure is indicated and sensed on a pressure gauge, and by a filtrate pressure transmitter on the filtrate side of the module array.

Hermanus relief road Rapid development in Hermanus and surrounding communities has led to a steady increase in volumes of local and through traffic. Increased tourism has contributed to this growth, and has extended peak traffic demand into periods of the generally regarded tourist season.

High traffic volumes over long periods, inadequate parking and road capacity, inadequate

pedestrian accommodation, and inconsistent road layout and markings have resulted in several traffic problems on roads in the Hermanus CBD and greater Hermanus area.

Motorists passing through Hermanus mainly use Main Road through the CBD, which is also the main route for those wishing to access the CBD area, or Marine Drive along the beachfront. These roads are severely congested during peak traffic periods.

The proximity of many restaurants and tourist destinations (such as Market Square, the Old Harbour Museum, and key whale watching areas) means that Main Road also carries a high level of pedestrian traffic. Motorists thus wishing to avoid Main Road and Marine Drive must use several smaller detour roads that serve the residential areas to the north of the CBD area.

Before the construction of the relief road During the 1990s, the Hermanus Structure Plan made provision for, what was termed, the bypass road. The bypass followed an alignment along Spence Street, Royal Street, and Lord Roberts Street. and a preliminary design was drawn up for this route by Ninham Shand Consulting Services. Another plan, namely the Hermanus Transportation Plan (compiled by Jeffares & Green in 1997), confirmed the need for a CBD relief road as part

of a larger municipal transportation system, which identifies a number of policy goals and objectives from such a system, namely: • providing mobility for residents, visitors, and through traffic • providing access to properties within the CBD and on the outside of the relief road • providing for safe traffic operations • supporting public planning objectives • minimising cost to taxpayers.

The total construction cost of the relief road was R22 089 549.58 and the construction period was 15 months. The commencement date was during September 2009, and completion date 2011.

Karwyderskraal landfill site Cell 3 The recent opening of the new third cell at the Karwyderskraal landfill site, by Overstrand mayor Nicolette Botha-Guthrie, was indeed a happy occasion for the municipality. The regional landfill site at Karwyderskraal had to remain closed for approximately the last three-year period, as the existing cell was filled to capacity and there was a lack of funding for building a new cell. The closure of the landfill site posed specific challenges to the municipality, with the landfill site at Gansbaai being the only other permitted landfill site in the Overstrand municipal area. All the refuse from the Kleinmond and Hermanus areas, therefore, had to be transported to Gansbaai for the past three years.

Refuse from the Kleinmond and Hermanus areas do not have to be transported to the Gansbaai land fill site any more, resulting in a smaller carbon footprint. The expected lifespan of the Gansbaai site will also be extended as a result of this project.

Kar wyderskraal is situated in a per fect area for a landfill site, due to the high-quality clay found in the underlying material. The clay material acts as a ver y good barrier between the waste and the underlying groundwater, due to its low permeability. The good high clay could also be used in the layer works, thereby reducing construction costs considerably.

The total project cost for building the new cell was R9.3 million. The project was funded by Overstrand Local Municipality, as well as a contribution of R4.1 million from the Municipal Infrastructure Grant by the Department of Local Government.

It is estimated that 155 000 tonnes of refuse can be dumped in the new cell, and it is expected to have a lifespan of approximately five years at current growth rates, before the next cell will have to be operational.

Preekstoel biofiltration water treatment plant The original Preekstoel Water Treatment Works (WTW), located in the scenic Hemel-enAarde Valley near Hermanus, was constructed in 1974, with a capacity of 12 Mℓ/d. The plant was extended in the 1990s to treat a total volume of 24 Mℓ/d. Until then, the plant was designed to treat mainly surface water from the De Bos Dam. Between 2011 and 2013, the existing plant was refurbished and an additional treatment plant has been completed for the treatment of borehole water. This plant represents the first fullscale biological iron and manganese removal plant in South Africa, with a total capacity of 10 Mℓ/d. Through the refurbishment of the existing plant, and the use of new technology, the plant’s capacity was increased to 28 Mℓ/day. Added to the biological plant’s 10 Mℓ/day capacity, the total treatment capacity of the plant became 38 Mℓ/day.

pipelines, namely: ensuring the continuous operation of the existing treatment works during the refurbishing process; and overcoming environmental and social sensitivities. During the rehabilitation process of the existing treatment lanes, only small sections of the existing Preekstoel WTW could be decommissioned, refurbished, and re-commissioned at a time, ensuring minimal disruption of the water supply and treatment system. Construction activities were also programmed to ensure that the full works was operational during the peak holiday periods. Although water restrictions were put in place, due to a severe drought period, no water supply cut-offs were required during any stage of the refurbishment period. Most of the borehole wells are located on private properties, while a large portion of the pipeline routes is also very environmentally sensitive.

Borehole structures were, therefore, designed to blend in with the environment, also taking into consideration the requirements of the property owners. Vast sections of power supply lines had to be installed below ground level to reduce visual impact.

The total project cost was R87 million, of which R21 million was contributed by the Department of Water and Sanitation, through the RBIG (Regional Bulk Infrastructure Grant).

Sixty-seven temporary jobs were created for local people during construction.

Overstrand Local Municipality has implemented various actions over the last number of years in order to quantify and reduce nonrevenue water and water losses.

The municipality adopted a water demand management plan as part of its turnaround strategy. The aim is to reduce water losses to 17% by 2017. The following activities form

Preekstoel WTW is located in the greater Hermanus area, known for its whale watching

part of the strategy, to support the achievement of the desired result.

Water pipe replacement involves the replacing of existing water pipes, which are known to be old and subject to frequent bursting, as well as augmenting the existing reticulation network, to ensure that sufficient water is available – even during the extreme peak holiday season. The project was implemented in Rooi-Els, Pringle Bay, Betty’s Bay, Kleinmond, Hermanus, Stanford, Gansbaai, and Pearly Beach – all coastal and predominantly holiday towns within the Overstrand Local Municipality.

The municipality has a 20-year water network master plan, and also a water pipe replacement model. The pipe replacement model considers various factors, such as recorded pipe bursts, pipe type, age of pipes, geotechnical conditions, geographical locations, and the potential impact of pipe bursts. The municipality also continually monitors the water losses in the various sections of the network, which also assists in determining the priority areas.

The project is in its seventh phase, and the

methods used include trenchless methods – such as pipe cracking and slip lining, where possible – and conventional open excavation. The value of work done to date is approximately R65 million, with 60 km of main pipelines having been replaced to date, var ying between 110 mm and 450 mm in diameter. This represents approximately 8% of the total network.

The use of trenchless technology reduces the impact on local residents and, by moling the house connections, damage to roads and the impact on traffic and residents were minimised.

Challenges during construction included: • being sensitive of the location of existing water mains and connections • avoiding damage to existing ser vices

HOT SEAT

MI KIND

of alternative MIBT Pragasan Chetty, managing director of MIBT, takes IMIESA’s Hot Seat to discuss his unique product – Mi Panels – an innovative, green building material with a plethora of applications for the African market.

Can you please describe the origins of the Mi Panel?

order to make it suitable for this environment?

PC The Mi Panel is a structurally insulated, lightweight concrete panel that was first developed, in 1971, in partnership between Indiabased Hyderabad Industries Limited and James Hardy, a major construction company based in Australia.

We have four critical aspects for construction anywhere in the world, but these four hold truer in South Africa than anywhere else: • The panel must meet the physical characteristics of brick and mortar as closely as possible in order to alleviate the fears of the end user.

• The more you reduce your dependence on wet works in the built environment, the greater success you will have with an alternative construction system.

• The construction method must be executed without difficulty and easily taught to, and understood by, people who are not conventionally trained in the construction environment.

• It must be affordable.

What was the intention behind developing this particular type of building material?

The most important consideration, at that time, was to find a rapid construction solution for outlying areas where accessibility was a problem. Conventional construction would not easily work in inaccessible areas, so an alternative to conventional brick and mortar was needed, but with the same characteristics that appealed to construction companies and the end user.

With the panel that MIBT produces in South Africa and the rest of Africa, what characteristics did you need to look at in

cement (CFC) sheeting, supplied to us, directly from Australia, by James Hardy. It is proven to be the best CFC in the world, with zero water penetration through the joints.

What makes the Mi Panel green?

The nature of green is embodied energy. The panels are made by means of an exothermic reaction, which creates a passive cooking process. There is no delamination. The sheets will not come off because they are chemically bonded in the reaction, not glued on.

Our electricity bill does not go over R8 000 a month. We run four to twelve motors, all of which can be accommodated with a generator, and we are able to conduct offgrid manufacturing.

What are the panels made of?

What impact does that have on the heating/cooling of a structure?

BASF supplies us with a unique product, Neopour, which is a graphite-impregnated, polystyrene lead, which enhances the R-value of the panel, and compressed-fibre

Mi Panels have an R-value of 0.303, making them 40% to 50% better than a nine-inch clay-brick wall. The important consideration in this regard is that, given the

“On any construction site, the more you rely on wet works on the site, the more you will be delayed in terms of mortar, material, PNG items, and so on. We are able to reduce the reliance on external products.”

14

IMIESA June 2015

threat that South Africa’s electricity supply poses to the economy and the need for artificial heating and cooling in a building, Mi Panels provide passive thermal efficiency, which reduces the reliance on an external source to control the ambient temperature in the house.

Can you demonstrate, by means of comparison, the time it takes to complete a Mi Panel structure compared to a traditional brick and mortar one?

Let’s take, for example, a 40 m2 BNG house; we find that we are not competitive in that environment, as we are too expensive for RDP housing. However, we are very well placed for affordable and gap housing. To have a fully fledged house that meets all the regulatory requirements on SANS 204 and SANS 10400, which is the new green building regulation promulgated by the SABS, we are able to do this in five days, while conventional methods would take two to three weeks.

HOT SEAT

“If you can imagine a building that can be made from brick and mortar, we can do it too. The physical structural properties of Mi Panels are stronger than brick and mortar.”

Furthermore, our 40 m2 house has 20% more floor space than a brick and mortar house. It would take us a day to put up a structure and four days to complete a classroom. Government is currently achieving a return of anything between six to eight weeks on a conventional 56 m2 classroom.

What skills are required to work with the material and what training is needed to optimally use the material?

There is no specific training needed. If you have zero experience working in the construction industry, we have a two-day training programme that can teach anyone how to build with Mi Panel.

What is the range of specifications that you are able to fulfil?

There is no limitation. If you can imagine a building that can be made from brick and mortar, we can do it too. The physical structural properties of Mi Panels are stronger than brick and mortar, as conclusively proven by the University of New South Wales and the University of Johannesburg. Our compressive strength over a 3 m height,

with a 600 mm panel width, is 148 kN; the capacity of the panel is 74 KN, far and away stronger than a nine-inch clay-brick wall.

In terms of our Agrema certifications, we are the highest certified Agrema system in Africa. We can go to four storeys high, with 11 different applications – from a small spaza shop to a four-storey hospital. Internationally, we have built eight-storey hospitals in Jakarta, multimillion-dollar mansions in Australia, and shopping centres all over the world. We have built mining camps for BHP Billiton and Reliance Industries in India. The range of clients and the different applications show that nothing impedes us.

What are the advantages of reducing on-site wet works?

On any construction site, the more you rely on on-site wet works, the more you will be delayed in terms of mortar, material, PNG items, and so on. We are able to reduce the reliance on external products because our entire manufacturing operation is internalised. This way, the product you receive on-site is ready-made.

With Mi Panels, you have the panels on-site; as well as small

tools, electric tools, chemical anchors, and nuts and bolts, which can all be safely stored away. The risk of materials theft is thereby also greatly reduced.

What is your current production capacity and lead time?

We have the largest facility of its kind in Africa. There is no other innovative building technology that comes close to us in terms of manufacturing capacity. We are currently able to manufacture 18 000 panels per month. Our lead time for a building project is six weeks; going forward, we realistically want to drop that down to four days.

Are there any logistical considerations that a contractor should bear in mind when engaging with MIBT? None, other than what you would have with brick and mortar. There is nothing out of the ordinar y; in fact, we limit your logistics because, when you transport Mi Panels, there is no need to transpor t multiple materials from various suppliers.

Can you tell us about a significant local project that MIBT has been involved in?

We built 18 classrooms for King Hintsa FET College in the Eastern Cape, on three different campuses: King Hintsa, Willowvale, and Centani. We did this in 24 days, which has never been done before in South Africa. The classrooms are beautiful and the college and students love them.

What are MIBT’s future plans?

MIBT is a hungry company that has just started out and, at this stage, we are actually struggling to keep up with the enormous demand. We want to supply all of Africa, from the Cape to Cairo. To execute this, we are looking for partners to expand our business.

We need the right partners to grow with us – preferably ones who have a long, established history in construction a strong track record for client satisfaction. We want to put up plants everywhere.

HUMAN SETTLEMENTS

Welcome to Pelican Park

A

CCORDING TO COUNCILLOR Tandeka Gqada, from the city’s Human Settlements Directorate, this is indicative in its budget allocation for these projects, which includes the upgrade of informal settlements, provision of services for backyard dwellers, major upgrade of rental stock, acquisition of land for new developments, and the development of integrated human settlements.

In its efforts to develop sustainable human settlements, with access to social and economic opportunities, the city has partnered with the private sector to develop projects that aim to support the lower-to-middle-income sector of the market while creating an environment for people to thrive in as their economic situations improve.

One cohesive human settlement The Pelican Park Development is a flagship project for both the City of Cape Town and the Western Cape government, as it represents the first Integrated Residential Development for the City of Cape Town, and the largest in the Western Cape, where families from different income levels will be living together in one cohesive human settlement.

Pelican Park is an 80 hectare piece of land situated near Grassy Park in the Western Cape.

This development is unique in its prime location, which incorporates breathtaking views overlooking the historical Zeekoeivlei Lake and nature reserve – a location more commonly reserved for upmarket developments.

The 3 200 house development is truly integrated and entails the provision of residential units, made up of a mix of fully subsidised,

partially subsidised (the so-called ‘gap market’) and open-market properties. In the fully subsidised market, the beneficiary households only qualify if they have a combined monthly income of less than R3 500 per month and are currently ‘backyard’ or shack dwellers who have never owned formal housing.

It is further integrated by including on-site amenities within walking distance of all homes, including a primary and secondary school, a health clinic, a small retirement village for the affordable market, a retail shopping centre, a fuel station, a library, and two commercial sites.

Making a way for everyone Since October 2012, over 1 600 of the 2 024 ‘breaking new ground’ units have been built and occupied, and the entire civil infrastructure completed. The developers have also sold and built 400 of the 765 gap units and 160 of the 423 market units.

The R750 million housing development was awarded to Power Construction, in 2012, as the turnkey developer for the city. The Power Group incorporated green elements into every detail of the planning and design of the development. As a result, all bonded houses have solar geysers, dual flush toilets, and eco insulation, and comply with SANS 10400 regulations.

The most significant innovation was the design and approval of the first bonded block house (non-cavity walls) in the Western Cape. This included a 12-month research and consultative process with the four major banks, the National Home Builders Registration Council, and the City of Cape Town. According to the developer, the major concern was water penetration/waterproofing in coastal conditions.

The City of Cape Town’s Human Settlements Directorate has been very active in the delivery of sustainable human settlement developments aimed at addressing the housing backlog and providing for the basic needs of the community.

BY LIESL FRANKSON

This innovation allowed Power Construction to sell the lowest priced free-title home in South Africa at R290 000. This also ensured that the developer was the first, and only, private company to successfully receive 160 FLISP approvals in the Western Cape. To date, over 150 FLISP (Finance Linked Individual Subsidy Programme) homes have been built and occupied.

According to Gary Power, marketing manager of Power Construction, the biggest hurdle was getting the bank and the Department of Human Settlements to agree on terms. “This was realised through great teamwork and a shared goal of opening up the market to home owners who could never afford a bond before,” he says.

“The process included consumer education and extensive groundwork. There were many challenges in terms of the legal processes that Power Construction had to champion, as the forerunners of FLISP. This has smoothed the road for other developers and contractors to finally make FLISP a reality,” he explains.

FLISP units include two-, three- and four-ina-row double-storey gap homes. These units are two bedrooms, 42 m2, and are placed on 60 m2 to 120 m2 erven. The size of the erven posed another hurdle, as some banks have

IMIESA June 2015

17

HUMAN SETTLEMENTS

never bonded homes on erven smaller than 120 m2. “We pioneered the way to removing yet another stumbling block, and now all four major banks have approved and funded bonds for FLISP homes,” boasts Power.

Integration beyond building houses Habitat for Humanity, a group dedicated to addressing the issue of poverty housing, and the Power Group have entered into a partnership to foster social development and cohesion in this community.

Habitat’s role, in partnership with the Power Group, is to bring about sustainable change in the lives of the new homeowners by inculcating a sense of citizenship, ownership, and the establishment of a cohesive and vibrant new community through Habitat’s Social Facilitation Programme.

Taking this a step further, the Power Group initiated and implemented the Pelican Park Owner’s Association (PPOA). Through the PPOA, Habitat is providing vital training to new trustees. “This is groundbreaking in that it’s the first of its kind in a non-gated village,” says Power.

ABOVE Since October 2012, over 1 600 of the 2 024 ‘breaking new ground’ units have been built and occupied, and the entire civil infrastructure completed LEFT 48 m2 market house

The process of establishing the association included registering a legal entity and establishing a founding document with conduct rules. Not only is the development integrated, but the trustees of the PPOA are from all segments of the development.

Habitat for Humanity is also providing extensive homeowner’s education prior to and after moving in.

“It’s only through partnership that we can deliver sustainable and integrated human settlements,” said Western Cape Minister of Human Settlements Bonginkosi Madikizela,

speaking at a Habitat-inspired Build Week held at the development last year.

“We need the developers to build quality, innovative houses; we need the financial institutions to assist with financing for potential homeowners; and we need the NGOs and beneficiaries to develop a culture of active citizenry, where people are encouraged to move away from positions of dependency to realising that they have important value to contribute in building our societies, and being the changes they wish to see in the world,” he declared.

In par tnership with various municipalities throughout the countr y, SBS Tanks® have played a vital par t in the roll-out of basic human rights such as access to clean water and dignity, with the provision of sanitation to millions of citizens. Mava Gwagwa, SBS® Water Systems’ key accounts and new business director, states that, since its inception, the company has successfully completed over 700 projects in collaboration with local and district municipalities. “There is a common perception that we only cater for potable water storage needs and smaller tanks. This is emphatically not the case, as our offering to the municipal sector extends to sewage and effluent, as well as wastewater treatment storage solutions. We are able to supply our Proudly South African products in capacities from 12 kℓ right up to 3 300 kℓ.”

The key to the company’s success lies in the modular design of its professionally engineered product. Says Gwagwa: “It is a fact that most communities that do not have access to safe water or basic sanitation are situated in remote, rural areas.

CCORDING TO A REPORT issued by the United Nations in July 2014, the urban population of the world has grown rapidly from 746 million in 1950 to 3.9 billion in 2014. Asia, despite its lower level of urbanisation, is home to 53% of the world’s urban population, followed by Europe with 14%, and Latin America and the Caribbean with 13%.

The world’s urban population is expected to surpass six billion by 2045 and the majority of this growth is expected to occur in Africa.

In a perfect world, infrastructure development would keep pace with a growing population, more often than not, though – because of the long-term nature of roads and other infrastructure – it is nearly impossible to accurately predict how a city will develop over half a century or more. This makes the work of city developers and planners particularly difficult, having to establish a working city with current issues and, at the same time, plan sufficiently far in advance to mitigate future issues.

A safe city is a prosperous city. The bigger a city gets, the more difficult it becomes to keep citizens safe. There are a number of factors that influence safety in a city and, like cogs in a well-oiled machine, they are

interconnected in complex ways that require creative solutions.

Shared prosperity According to a presentation given by Richard Chace, CEO of Global Security Industry Alliance, given at the Huawei Safe City Africa Summit 2015 held in April, “In a city, when prosperity is absent or restricted to some groups, enjoyed in only some urban areas, used to pursue specific interests, or justified for financial gains of a few to the detriment of the majority, the city becomes a battleground where the right to prosperity is claimed and fought for.”

Remedy to global crises According to Chace, the cities of the future must have certain characteristics to function optimally. Cities must be: • Pragmatic: Cities can act as the forums where the trust, respect and inclusiveness that are part of any remedy to a crisis can be built.

• Connected: Cities can forge new partnerships and local social pacts, which, in turn, can strengthen national governments in the face of global challenges.

Safeguarding our

future

The concept of smart cities is one that is quickly gaining ground, as leaders look at new ways to tackle the intricacy of rapid urbanisation. Safety can be improved with forward thinking and the clever use of technology. BY BEATRIX KNOPJES

•S ocial: Acting locally in different areas and spaces, urban responses to crises can be structured and included in national agendas to improve efficiency, with better chances of flexible responses and more beneficial effects.

• Local: Cities find themselves in more privileged positions than national governments to negotiate and agree on responses with local stakeholders.

State of the city In his State of the City Address on 6 May 2015, executive mayor of the City of Johannesburg, Mpho Parks Tau, made the statement that Johannesburg is “a city in which today is clearly better than yesterday; which every day finds new ways to work with its people to ensure tomorrow will be better than today.”

In line with this statement, he recognised the importance of digitisation to launch the city into the 21st century: “Digital access is becoming as much an equity issue in our society as access to water and electricity.”

He also emphasised the importance of using ITC infrastructure to facilitate the creation of a safe city: “We are innovating in order to transform how we run the city for the 21st century. For the people walking the streets of the inner city today, feeling unsafe, our new intelligent operations centre links together our upgraded CCTV cameras and gives us eyes on the street.

The intelligent predictive software and the new cameras can detect patterns of behaviour that arouse suspicion. This allows us to see and prevent crime more quickly, and link criminals and their vehicles to specific crime sites.”

Innovative ICT A safe city requires the use of a consolidated IT platform that converges public safety information – obtained through channels such as video surveillance, access control and other identification technologies – with multi-agency collaboration between parties such as emergency services, road and traffic agencies, and law enforcement authorities. It combines the security, safety, and operational aspects of a smart city.

The acceleration of global urbanisation and the proliferation of the Internet will drive the convergence of ICT and urban infrastructure. Countries worldwide are actively formulating plans for the development of safe and smart cities to seize new oppor tunities generated by global urbanisation.

At this year’s Huawei Safe City Summit, safe city project leaders from many countries – including Madagascar, Kenya, the Republic of Trinidad and Tobago, and the United Kingdom – shared their experience on ICT

best practices to enhance public safety with innovative ICT. Randimbisoa Blaise Richard, Madagascan Minister of Public Safety, said at the summit: "As a multicultural country, Madagascar has gone to great efforts to meet the increasing requirements of economic growth and social stability triggered by the acceleration of globalisation. Our major responsibilities are to maintain social order and combat crime, working to ensure that Madagascar is a safe country to live, travel, and invest in.”

Forrester Research principal analyst Jennifer Belissent also spoke about the role of ICT solutions in protecting a city’s safety, and making cities safer and smarter. She went on to explain, “Urbanisation means that a growing population depends on cities to meet their social, environmental, and economic needs. Safety is fundamental to those needs, and public safety is a concern of city leaders – whether it’s preventing crime, reducing infant mortality, or mitigating the effects of natural disasters. Better access to data and new analytics tools make that job easier. A safe city not only improves liveability, but also encourages economic growth and ensures sustainable development. That makes safety a key element of any smart city.”

Smart water meters offer endless benefits

The world’s most accurate commercial turbine meter.

A town in the Eastern Cape has benefited from smart water metering technology, which has contributed to a reduction in water leaks and wastage, as well as ensured an increase in municipal revenue.

J

ANSENVILLE, IS A town in the Ikwezi Local Municipality, within Sarah Baartman District Municipality in the Eastern Cape, and covers an area of approximately 25 km2. The town has 1 600 residential units and approximately 6 000 residents.

Early in 2014, Elster Kent Metering was approached by the then Department of Water Affairs to put forward a solution that would generate revenue by accurately recording the water used by residents and businesses in Jansenville.

The municipality was not generating sufficient income for the provision of its water services.

One of the main problems was that not all of the properties in Jansenville had water meters, which resulted in the municipality receiving a monthly flat rate from all consumers, regardless of the amount of water being used by each. Water was also being lost through water leaks, which could have been resolved with the installation of water meters. A solution that would attend to these challenges was needed.

The Elster Kent H5000 Hybrid Waltmann Water Meter

ABOVE Alternative meter DW9440 with AMR (15 mm KSM, probe, and MIU) connected and concealed in the box BELOW 15 mm Elster Kent KSM domestic water meter in DW5770 meter box with probe and MIU attached

Benefits of the technology The solution presented was Elster Kent Metering’s complete automated meter reading (AMR) technology. The system is efficient, in that meter readers do not need access to a customer’s property in order to collect water meter data.

This technology offers a quick, efficient way to obtain readings without having to view the meter register, unless necessary. Mike Phillips, Elster Kent Metering’s regional sales manager: Eastern Cape, explains: “We assist customers in deploying the latest technologies that enable them to improve revenue, reduce operating costs, and enhance customer ser vice. Elster Kent Metering offers a broad range of intelligent metering solutions in the form of

AMR systems. Our approach allows utilities to implement flexible, cost-effective reading systems that can be integrated into today's operations, with the added benefit of allowing the system to evolve as the utility grows, or as technology advances.

“To read the 861 currently operational units in Jansenville now takes a total time of 3.5 hours, with 100% accurate data being provided to the client,” comments Phillips.

Various professionals were involved in the project. From Elster Kent Metering, the project was headed up by Mike Phillips and Jacques-Louis van der Linde, sales and AMR manager. ENCO is the approved Elster Kent Metering AMR supplier and installer for the Eastern Cape and surrounds, and, together, the team has the capability to install 400 complete AMR units per month, using one team comprising just four workers.

Benefits for residents and the municipality The residents of Jansenville have also benefited through the project. Residents no longer have to rely on estimate water meter readings, as water meter readings are accurate for their actual consumption.

Early leak detection, as a result of the installed meters, has helped to significantly curb water wastage. The project has also contributed to the upliftment of the community, as ECNO has trained locals from Jansenville in the installation of the technology. These community members now have the expertise to work on other such projects in the area.

From a municipal perspective, the project has improved revenue through accurate consumer billing. Other benefits for the municipality include the reduction of operating costs, the enhancement of customer

28

service, and, most importantly, the conservation of precious water resources.

The project, which commenced in May 2014, has taken place over various phases.

According to Phillips, “The initial phase included the town centre and business areas of Jansenville. The second phase included the rural and residential areas, and the third will comprise a further continuation of these.”

Commenting on future developments resulting from the Jansenville project, Phillips says: “We are currently busy with the completion of Jansenville and Klipplaat. There has been considerable interest from surrounding municipalities that have come to view the live system in operation and have seen the value and benefits of the system.”

The right team Phillips says AMR can only work if the project is handled by an accredited contractor who has experience with installing and running AMR systems from the start to the end of the project (including maintenance).

“We at Elster Kent Metering have formed a good working relationship with ENCO and, as a team, we have accomplished something special that reduces water wastage and generates revenue for the municipality,” says Phillips.

Peter Artz, director of ENCO, comments: “We are ver y proud to be a part of such a game-changing project. We have worked hand in hand with, and received incredible support from, Elster. Together, with Elster Kent Metering, we are providing a product and ser vice of the highest quality.”

WASTEWATER TREATMENT

A breath of fresh air

A world-class membrane bioreactor (MBR) plant at Malmesbury Wastewater Treatment Works is able to treat up to 10 Mℓ per day of domestic and industrial wastewater, using a range of industry-leading positive displacement blowers.

M

ALMESBURY WASTEWATER Treatment Works plant manager Francois Malan reveals that the Western Cape-based facility is one of only two in the country that boasts an MBR plant, which is designed for nitrification-denitrification biological excess phosphorus removal.

“Continued urban growth prompted an upgrade of the plant, in 2012. The old biofilter plant was decommissioned, and the old activated sludge plant was incorporated into the MBR as a hybrid system, which reduced the overall cost of the upgrade by maximising the use of existing infrastructure, and reducing peak wet weather loading on the membranes,” he explains.

Malan indicates that the control and instrumentation systems were also subsequently modernised, and the plant commissioned three GM150L and three GM80L positive displacement blowers produced by Germany-based Aerzener Maschinenfabrik (Aerzen), a world-leading specialist in the design and manufacture of rotary air and gas conveying equipment.

Fine bubble diffused aeration The new instrumentation enables fine bubble diffused aeration (FBDA) – which provides substantial and efficient mass transfer of oxygen to the water, by generating millions of tiny air bubbles that rise from the treatment plant tank floors. FBDA is widely recognised as the most energy efficient

and environmentally sustainable wastewater treatment system worldwide.

Oxygen is vital in promoting respiration for microorganisms in wastewater treatment.

The oxygen, combined with the sewage food source, allows the bacteria to produce enzymes that help break down the waste so that it can settle in the secondary clarifiers or be filtered by membranes.

Sufficient dissolved oxygen levels in the water improves the purification process and eliminates offensive odours caused by anaerobic decomposition. The use of pure oxygen can also reduce the production of foaming and volatile organic compound emissions caused by excess off-gas.

Malan indicates that, following the FBDA process, some of the treated wastewater is reused for cleaning the inlet works drum screens and irrigation purposes. “The water is more efficiently treated to enable us to recycle greater quantities, which, ultimately, reduces overhead costs and wastage of this precious resource.”

Minimal disruptions The Aerzen positive displacement blowers, installed at the Malmesbury plant,

are distributed locally, through Airgas Compressors, Aerzen's sub-Saharan subsidiar y. Airgas marketing co-ordinator Andreas Stubel notes that the on-site positive displacement blowers ensure oil-free conveying.

"No lubrication is required in the conveying chamber, as the rotary pistons revolve without making contact with each other or the housing. This guarantees that the air being conveyed remains free from contamination of lubricants and wear particles," he states.

The Aerzen positive displacement blowers’ handling capacities range from approximately 30 m³/h to 65 000 m³/h, in either a vertical or horizontal flow configuration. They feature an operational pressure of up to 1 000 mbar, and suction of up to -500 mbar.

According to Malan, the Aerzen positive displacement blowers boast superior quality. “The high quality of the equipment ensures minimal disruptions as a result of breakdowns, which is essential in this operation. Airgas also provides greater value with its proactive customer support service.”

Despite the efficiency and success of the upgraded wastewater treatment works, Malan admits that the Malmesbury plant still faces challenges. “Loadshedding is highly disruptive and, given the fact that the equipment is power-intensive, we may seek to adopt even more environmentally friendly operational processes in the near future to overcome this challenge,” he concludes.

‘Demistifying’ the future of

wastewater treatment

M

ORNÉ VAN WYK, I-CAT technical manager, indicates that the company’s new system for wastewater treatment has been well received by the local market and trials have proven that the concept is feasible.

Van Wyk points out that the evaporation process can be carried out naturally, in solar evaporation ponds, or by mechanical evaporation machines. “Natural solar evaporation is often limited by land availability and the cost of constructing additional storage ponds, not to mention the added cost of clean-up and revegetation,” he explains.

This is where evaporation machines come in. According to Van Wyk, these machines can rapidly increase the evaporation process, with minimal footprint. “Space can be utilised up to 14 times more efficiently

than ponds, as evaporation machines are compact, reliable, and efficient, and can be transported to numerous sites.”

The evaporation machines can also be used as low-cost additions to enhance evaporation on existing containment ponds, or to minimise new pond surface area. I-CAT Environmental Solutions currently offers two different types of evaporation solutions, namely water atomising evaporators and water fracturing evaporators.

Water atomising evaporators Van Wyk explains that a fan compresses air through a tapered barrel, and propels controlled-sized water droplets that are created via nozzles.

“This is best for larger areas, where wastewater contains lower dissolved solids or minimal particulates. I-CAT has spent a

considerable amount of time on research and development on evaporation solutions, and we are in the process of introducing this option to industrial clients, as part of our value-added service offering.”

Water fracturing evaporators Through this process, water is fractured through a high-speed fan and propelled into the air. Van Wyk states that this solution is best suited for smaller areas, where wastewater contains high volumes of solids and large particulates.

“We are currently in the process of supplying this solution to two large projects in South Africa, both of which commenced in early 2015. I believe that this could lead to considerable growth for I-CAT moving forward, as we continue to develop practical and cost-effective solutions for specific challenges experienced by our clients,” he concludes.

Decentralised

NUWATER

treatment solutions Like many countries around the world, South Africa is suffering from relentlessly increasing demands on its water and wastewater infrastructure.

A

S TRADITIONAL LARGE centralised infrastructure projects fail to materialise, and service delivery fails to keep pace with growing demand, an alternative model of rapidly deployable, decentralised, or distributed, infrastructure is gaining support as a viable alternative to plug this demand-supply gap.

NuWater is recognised as a leader in rapidly deployable modular solutions that can be readily scaled and adapted to match changing treatment requirements.

The company’s leadership is demonstrated in its world-class projects, both in South Africa and internationally. It is also supported by well-respected research organisations such as Frost and Sullivan, which recently awarded NuWater its prestigious Best Practice: Customer Value Leadership award for its ‘modular and mobile’ industrial wastewater treatment solutions.

According to John Holmes, NuWater CEO, the growing trend towards decentralised infrastructure is reflected in the company’s expanding customer base and opportunity pipeline. He says, “We are seeing a steady increase in enquiries from both industrial and municipal customers for our plants and services. In particular, customers are recognising the value of our full-service own and operate model, where we provide water and wastewater treatment as a service rather than requiring upfront investment on the part of the customer.”

Holmes continues, “Our business model is focused on reducing the barriers to successful project development and execution. There is no question that the demand for water and

wastewater treatment services is there, but such projects are still seen as expensive, difficult to finance, and technically risky.

NuWater’s full-service approach removes both the technical and commercial risk from the customer by retaining ownership and operational responsibility for its plants, while offering a cost-effective and almost immediate solution.”

challenges that have tested the durability and reliability of our plants. As we continue to own and operate most of the plants we have delivered to customers in the sector, we are incentivised to invest further in technology and product design to improve the reliability and efficiency of these plants. These product improvements have, therefore, benefited both existing and new customers alike.”

Modular and mobile

Moving into the municipal sector

NuWater honed its modular and, where relevant, mobile plant designs, along with its commercial value proposition in the international mining sector, working with customers such as Anglo American and Gold Fields.

Holmes explains, “We have owned and operated possibly the largest modular and mobile water treatment and desalination plant in the world at Anglo American’s New Vaal Colliery for almost five years, and have treated more than 15 billion litres of mine wastewater back to potable water standards. What started as a short-term two-year project has evolved, and will continue until at least 2018. With a demanding customer like Anglo, such success does not come without a lot of sweat, and a few tears, but the end result is that we developed the technical and commercial credibility to be a leader in this emerging decentralised, flexible water infrastructure space.”

NuWater’s success at Anglo has been emulated at other leading mining customers such Gold Fields, in Ghana, where the relationship continues to develop with further contract extensions. Holmes continues, “The mining sector presents some unique

More recently, NuWater has begun to offer its solutions to the municipal sector, where Holmes has observed changing attitudes.

“The municipal water sector has, historically, been very conservative and risk averse, resulting in minimal innovation over the decades. However, the social and political pressures associated with poor service delivery have resulted in a rethink and a new appetite for both technical and commercial innovation.”

This new progressive thinking has resulted in NuWater’s first municipal contract with the eMalahleni Local Municipality, where NuWater will augment the city’s existing water treatment plant with 20 000 m3/day of rapidly deployable modular treatment capacity for an initial three-year period.

Holmes concludes, “It is very pleasing to demonstrate that our plants and our commercial value proposition are as equally applicable to the municipal sector as they are to our customers in the industrial sectors. We are very excited about our entry into the municipal sector, as we believe we can make a real and immediate impact on service delivery.”

BUILDING BUSINESS

P

ARTNERSHIPS AND JOINT ventures are most successful when due diligence and operational fundamentals are well cemented and executed, establishing commitment, trust, and comprehension and proper planning.

One such partnership has not only survived for 10 years, but has secured high-value projects on its own terms and as joint ventures with its South African partner company. UWP Consulting (Tanzania) opened its doors as a partnership between Tanzanian professionals and South African engineering consulting practice UWP Consulting a decade ago.

The Tanzanian business has successfully completed roads and water projects valued at more than $10 million, with structures and capacity-building assignments further expanding its portfolio in the last few years.

UWP Consulting (Tanzania) was registered as a local engineering consulting firm in May 2005, with five local professionals holding 51% of the shares and UWP Holdings 49%.

Shared vision The company was started after Henry Catma, an engineer based in Dar es Salaam,

The right partners

for cross-border success

responded to UWP’s search for an individual or small company to form a joint venture in Tanzania. The timing was particularly good, as Catma and four other Tanzanian professionals were in the initial stages of establishing a local company called Tangroup Professionals Limited or Tanprol.

“It was easy to integrate Tanprol with UWP SA to form UWP Consulting (Tanzania) since both were targeting the same markets,” says Catma, who has served as managing director of the company from its inception.

The other founding shareholders in the company are not involved in day-to-day operations.

Expanding through opportunity For several months, Catma was the only fulltime employee in the fledgling Tanzanian business, but the first major breakthrough came in 2006, when three municipal road upgrading projects were awarded in succession and two

more engineers joined the firm. Today, UWP Consulting (Tanzania) has a staff complement of 20, including six professional engineers, and has successfully completed numerous projects alone and in JV with UWP SA. Notable projects include the design of the 65 km Tanga-Horohoro and 78 km PeramihoMbinga roads, and the supervision of the Lower Ruvu water treatment plant, which provides potable water to Dar es Salaam.

Diversification through new JVs The company is looking to increase its client base by exploring opportunities in the private sector, in mining, and through joint ventures with other professional firms in airport, railway, and harbour projects.

Catma concludes, “We also hope to implement a strong succession plan by employing young professionals, providing training, and giving them shares opportunities."

A slow and steady recovery in the construction industry is predicted over the next five years, with gradually returning business confidence driving new investments in the industry and its key suppliers.

Predicting growth

beyond 2020

A

S THE LARGEST SUPPLIER of materials for construction projects, the readymix concrete industry is seeing increasingly more investment in the market, in anticipation of more buoyant and profitable times in future.

Large cement suppliers have already made acquisitions of some of the major readymix companies, and talks are apparently afoot for more acquisitions and mergers at the top end of the market.

The reasons for the shift in optimism are based on a number of positive factors that are seeping into the market, in the form of a rising number of plans being passed and far easier access to mortgage bonds. In addition, the allure of government’s R800 billion infrastructure investment plans for the period up to 2020, and its promise to build 1.5 million RDP houses by the same period (at a cost of over R30 billion per annum), is proving to be a big incentive for investment in the building materials industry.

Investment returning According to a recent report compiled by BMI, on behalf of the Southern Africa Readymix Association (Sarma) and the closely allied Aggregate and Sand Producers Association of Southern Africa (Aspasa), tough market conditions, since the worldwide recession, have led to underutilisation of manufacturers’ capacity. In addition, they have stifled

investment in the construction and related industries and led to some stagnation of the readymix concrete industry.

South Africa’s slow recovery has also led to the large construction companies sourcing up to 60% of their revenue abroad. The viability of transporting heavy building materials over long distances is poor and, as a result, the lack of investment from these firms has dampened growth to an extent.

Positive growth signs and returning investment are, however, bringing back a more positive sentiment to the market. Simultaneously, the increasing demand is also leading to a large number of new operators establishing themselves in the sector, which is effectively absorbing any real growth that the established players would have otherwise enjoyed.

Trending upwards Commenting on the report, Nico Pienaar, who sits on the boards of both Sarma and Aspasa, says that signs of renewed growth are positive, but are expected to be slow and measured, at least for the next two years.

Some negative factors, including electricity shortages and low demand globally for commodities, may slow growth and have a negative effect on business sentiments locally.

However, he said positives outweigh the negatives, and stability in interest rates and rising house prices all tend towards supporting growth. Residential building plans passed

TOP Readymix concrete allows for innovative building techniques to be used to meet government's promise to build 1.5 million houses by 2020 ABOVE Nico Pienaar, Aspasa and Sarma

are particularly encouraging, especially in the affordable housing market, while retail centre construction is also growing at a good rate.

“One of the positive outcomes of the recent recession is the trend for businesses to return to quality and specification of quality produced materials. In our industry, there is increased cooperation between professional bodies who are working towards the specification of only accredited building materials to be used on-site to avoid failures, and possible disaster in the event of structures collapsing.

Members benefit “Companies can no longer afford the risk of buying unregulated products and, as a result, we are seeing a number of large consulting engineering firms, contractors, municipalities, and industry bodies writing in clauses, specifying only accredited materials to be used on their sites. This is obviously positive for Aspasa and Sarma members, who should win back lost ground as a result of start-up operators undercutting prices etc.,” concludes Nico.

Driving customised solutions into Africa Having supplied product throughout Africa for 15 years, Chryso Southern Africa has amassed an extensive project reference base. Its success is largely, although not solely, due to the strong relationships it has formed with contractors across Africa.

T

HIS IS A RESULT of the high level of technical expertise and support that Chryso Southern Africa is able to bring to each project. Repeat business is commonplace for the company as we do not simply supply product into the region and then remain passive,” says Armand van Vuuren, commercial manager at Chryso Southern Africa.

“We believe that active participation and ongoing interfacing, with both our new and repeat customers, have enabled us to establish such a strong footprint in Africa,” he continues.

Customised solutions

IMIESA June 2015

The first step in gaining the trust of stakeholders, says Van Vuuren, is to acknowledge that each contract is different. “Every project has its own dynamics, and supplying admixtures is certainly not a case of one product fitting all applications. We have developed the ability to assess each project on its own merit and then recommend a fit for application solution that takes into account all aspects, such as climatic conditions, raw materials (including aggregates and cement), the time allocated for the project schedule, and any other relevant factors that may affect its timeous completion.”

As part of an international organisation with a major global footprint, Chryso Southern Africa has access to extensive research and development facilities and a team of highly experienced and knowledgeable engineers who are available to assist with any technical queries.

Van Vuuren points out that being able to understand how its customers operate in the different African countries is extremely important, and this allows the company to customise a service supply chain for each project site. This ensures continuity of product supply,

especially for long-term contracts. Added to this, an intimate knowledge of local conditions allows the company to select the most appropriate admixture for the given aggregates and cement mix in each country or region. This is complemented by technical support from the export team, in collaboration with people who speak the local languages.

Targeted operations With three facilities operating in Johannesburg, Cape Town, and Durban, all products are readily available and can be shipped to customers across Africa using the most appropriate shipping method.

“If, for any reason, one of the three plants is not able to supply product, we are guaranteed that the other two will be able to assist. In this way, we are able to meet the demand for product in both South Africa and up into the continent,” Van Vuuren explains.

In general, product is shipped from Cape Town to West Africa, from Durban to East Africa, and by road freight from Johannesburg to the SADC region. “Reliability of supply is critical in Africa and customers have come to rely on the fact that we are able to manage the logistical flow of our products to sites all over Africa, including those in the remotest areas. The logistics chain is one of the most critical aspects of our success, and our ability to adjust and fine-tune this for each country is something that differentiates our service delivery,” Van Vuuren says.

Ongoing training for the South African office-based support team ensures that the team has a thorough understanding of the logistics involved. The team is dedicated to this function to ensure a seamless transition from order of product to client delivery.

In addition to first-class manufacturing facilities, Chryso Southern Africa also has access to its in-house laboratory in Johannesburg,

where specialised mix designs are tested to determine the most appropriate solution for each project. This is supported by alliances with a number of concrete laboratories in various African countries.

Chryso Southern Africa has recently been very active in northern Mozambique, where solutions were provided for the precast facilities servicing the Nacala railway and harbour projects, with precast manufacturing facilities operating in both northern Mozambique and Malawi. Aveng Manufacturing Infraset, in Tete, and Mota-Engil, in Malawi, were contracted to supply precast railway sleepers to this project, while Chryso Southern Africa supplied products from its Premia range of superplasticisers to all the contractors’ precast yards. “Superplasticisers were selected, as these would ensure high early strength and maximum water reduction in the production of the railway sleepers,” says Van Vuuren.

He adds that the supply extended beyond the precast manufacturers in the region, with a call for product to be supplied to the contractors responsible for the in situ civil structures such as the bridges, stormwater culverts, and drainage. Much of the product used by these precast manufacturers and contractors was transported either directly by road or via sea to the Nacala harbour. Chryso products were also used in the construction of the harbour facilities.

“In another example of the responsiveness that we are able to provide, in terms of customer needs, specialised demoulding oil was imported from France for one of the precast manufacturers.

While we are able to supply releasing agents from our South African operation, this particular contractor had previously used this product in Europe for its steam curing applications and Chryso, as part of a large global organisation, was able to secure the product the customer had requested,” says Van Vuuren.

In addition to northern Mozambique, the company has representation through distributors Concrete Additives in Namibia and Material Testing Services in Botswana. A full range of products is being supplied for a number of projects in these countries, including precast and in situ construction. Van Vuuren says that these distributors have an in-depth understanding of the markets in each country and maintain close relationships with their customers.

He adds that shopping centre development in Central Africa is a growing market sector with a major drive from South African developers. Chryso Southern Africa is involved with the majority of these projects, as it has the ability to provide product ex stock and service the cross-border sites with a full range of admixtures.

Van Vuuren says that Chryso Southern Africa has recently entered into agreements with companies in Angola, Zambia, and Ghana with the express intention of providing the same levels of service and support to its customer bases in those countries. “This move is in line with the company’s intention to further extend its representation in Africa. Export sales have grown significantly in the last few years and it is critical that we remain close to our customer bases so we can best service their needs,” he concludes.

Consignees of road freight, as well as those receiving loads, will need to carefully manage and administrate vehicle freights to prevent prosecution, in terms of recently promulgated overloading legislation.

Consignees and consignors

liable for overloading

I

N TERMS OF THE legislation, authorities may prosecute both consignees of freight, as well as consignors, if they are found to receive and accept overladen vehicles.

The onus will also be placed on the parties to produce and keep record of every truck load undertaken for a period of at least five years, while drivers should have the required load documentation with them at all times.

Speaking at a transportation workshop, held on behalf of the Aggregate and Sand Producers Association of Southern Africa (Aspasa) and the Southern Africa Readymix Association (Sarma), road traffic legislation expert Alta Swanepoel advised companies, which either transport or receive regular loads of goods, to be aware of the changes in legislation, in order to avoid prosecution in future.

Road damage “In terms of the National Road Traffic Amendment Act, No. 64 of 2008, the transportation of freights such as sand, stone, and concrete will need to be very carefully managed, as all loads measured across the entire vehicle, or per axle, will need to comply with the vehicles specifications as well as legal limits.

Extra precautions will also need to be taken to prevent shifting loads that may cause any one axle to carry excessive weight, which will deem the entire vehicle to be overloaded.

“The legislation arises from parliament instructing the Department of Transport (DoT) to stop overloading where it starts. Faced with billions of rands of roads damage bills on an annual basis, parliament said the current overloading legislation needs to be changed. As a result, the DoT has created a national overload control policy, as part of which the Minister of Transport has begun enforcing the existing National Road Traffic Amendment Act. “Failure to comply is a serious offence that carries a maximum penalty of a R240 000 fine, or a six-year prison sentence, or both.

The enforcement of the legislation is, however, expected to have a positive effect on the percentage of overloaded vehicles on the road, as overloading will be stopped at the source.

This, in turn, will lead to less damage to our roads and less costly infrastructure repairs,” said Swanepoel.

42

IMIESA June 2015

She explained that more careful attention will need to be paid by companies at the point of origin of loads, as well as where they are received. Accurate documentation will need to be generated and systems put in place to ensure compliance, from the points of loading to offloading. Additional requirements, such as proof of insurance per load and spillage prevention measures, also need to be noted by all parties concerned.

Cost concerns The director of both Aspasa and Sarma, Nico Pienaar, said the enforcement of the National Road Traffic Amendment Act would have a cost implication for companies, as better administration would be needed and would require extra personnel in many instances. Also, companies will need to purchase accurate weighing equipment to ensure vehicles are accurately loaded and weighed.

“We, therefore, call on government to enforce the legislation equally across all sectors. In our experience, the legal and scrupulous operators

TOP LEFT Aspasa and Sarma director Nico Pienaar TOP RIGHT Road traffic legislation expert Alta Swanepoel ABOVE Delegates taking notes at the recent transport workshop

across the country will be forced to turn away small operators whose vehicles do no comply.

Less-scrupulous operators will, however, keep on loading them up, and, unless the Act is properly enforced, our members will be at a disadvantage,” said Pienaar.

He concluded that compliance and documentation, as proof of compliance, is critical, and strongly suggested that road transport managers become familiar with the requirements of the Act, as well as the administrative burden that it entails. “It may also pay to engage the services of a road traffic legislation expert, such as Alta Swanepoel, in order to ensure necessary steps are taken to proactively prevent fines and prosecution in future.”

Retaining key points

W

HILE GUIDELINES SUGGEST that retaining walls need to be designed to ensure safety and efficacy for the installer and wall owner, they routinely fall down or degrade into a state of disrepair, which generates a desire for better-built walls, using better materials, and using a different system.

The following aspects should be investigated and clearly defined: • the height and length of the wall, its function, and the loads it must cope with in all directions during construction, post construction, and long-term expectations • what materials are best to satisfy the requirements of items listed in the previous point • location information and tests to determine the in situ soil, water distribution, and backfill material to be used behind the wall

• the period of construction and its influence on other associated activities on the site or adjacent to the proposed retaining wall • once all the previous points have been resolved, a comparison of the effective systems.

What can be expected by the contractor, followed by the consultant, then the owner, and, lastly, the public, if a basic and systematic approach is not followed?

• The contractor will lose money and time as he struggles to cope with poor drainage design, displacement of elements, and possible localised or section failures.

• The consultant could lose credibility in his

assessment, design safety, and site supervision abilities.

• The owner could end up paying more for less and be unsatisfied, living with an end result that makes him perpetually unhappy.

• The public tells a story of where a retaining wall has scarred the land, and this location might need to be avoided.

Responsible companies invest in R&D and collaborate with engineers, and environmental and architectural professionals to arrive at retaining wall solutions that satisfy all parties. From the Cape to Cairo, Maccaferri Africa seeks to satisfy all criteria to conserve its long-held reputation.

Renewable revolution well underway

A

CCORDING TO CRAIG Pace, director at international heavy lift, abnormal transport and installations specialist Vanguard, this revolution has already brought substantial benefits, saving the economy billions of rands in diesel and coal that Eskom would have had to burn to keep the lights on.

“A recent report from the Council for Scientific and Industrial Research shows that the 1 600 MW of renewable energy installed by December 2014 has saved the country over R5 billion,” says Pace.

He says that 32 renewable energy projects had already been completed and connected to the grid, with government planning to more than double this figure by reaching 3 625 MW by 2030.

“What is really encouraging about these developments is that they are producing electricity at a very competitive cost – so that the net financial benefits of renewables will remain positive, even in future when the national grid is less constrained,” he explains.

The Integrated Energy Research Centre at CSIR reported that the cost per kWh of renewable energy for new projects is now well below R1 for solar photovoltaic (PV) production and between 60c to 80c for wind projects.

“The government’s three Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) bid windows have procured more than 60 renewables projects, with combined capacity of 3 900 MW,” says Pace.

“Another 77 bids were received in the fourth REIPPPP window last year, indicating the enthusiasm and investment appetite of many foreign companies.”

The private investment associated with the projects procured to date amounts to R140 billion.

Vanguard has been integrally involved with a number of pioneering wind farms around South Africa in recent years, according to Pace.

“We have engineered efficient solutions for dealing with the large and complex wind turbine components being imported for wind farm projects – from discharging the vessel and specialised transport requirements to the hard stands, on-site lifting/erection, and electrical installations of 108 wind turbine generators,” he states.

Among the recent contracts completed have been the West Coast One wind farm, near Vredenburg on the Western Cape coast, where Vanguard erected 20 Vestas V90 2.0 MW turbine generators with its GTK1100 crane, and the Chaba wind farm, near Komga in the Eastern Cape, where the company discharged

Other projects include the Grassridge wind farm, also near Port Elizabeth; the Noblesfontein wind farm, near Victoria West in the Northern Cape; and Metrowind’s Van Stadens wind farm, in the Eastern Cape.

“These contracts have shown that Vanguard is the only South African-owned company with the expertise and capacity – including fully licensed and registered equipment – to offer a full turnkey project solution to the growing wind-energy market. Our commitment to clients is always to deliver on time and within budget, without compromising safety,” concludes Pace.

Vanguard’s fleet of specialised equipment includes the GTK 1100 telescopic mobile tower crane – the only unit in the Southern Hemisphere – which has proved invaluable in many of the wind farm installations.

Commitment, passion, and reliability Tienie Ferreira, director of D’Avino South Africa, discusses building strong relationships through D’Avino's exemplary product and after-sales service.

Can you put the the D’Avino brand in context?

TF D’Avino was established in Italy, in 1950. This family-owned business is based in Naples, Italy. It distributes its self-loading concrete mixers worldwide, particularly to developmental regions such as South America, Asia, and Africa, where batch plants may not be available close to construction projects.

Why a self-mixing concrete mixer?

The D’Avino mixers allow you to produce concrete on-site using raw materials – to the exact MPa and quantity required. It is cost-effective and ideal for use on rural sites,

where batching plants may be too far. It can, obviously, also be used on urban sites.

Generally speaking, our 4 m3 concrete mixer is the product that most interests the local market.

How well does it operate in the local context?

When a machine operates in a rural environment, everything must be uncomplicated. The D’Avino mixer complies with this criterion; it is uncomplicated, includes components locally available, and is easy to maintain on-site. We piloted a machine and utilised it for 1 250 hours, which enabled us to do our own tests to make sure that

it functions optimally in the South African environment. The results have been extremely good: there were no breakdowns or warranty claims during the testing phase.

What does the brand offer in terms of after-market support?

Our philosophy is that the salesman sells the first machine and after-sales service sells the rest.

The brand offers parts availability, and we also have support from Italy. As far as support is concerned, I am satisfied that customers will get the best service and our dealers are available 24 hours a day, 365 days a year.

What sets you apart from other players in the same market?

D’Avino offers conventional and unconventional machines.

The 360 Delta 4 rotates 360 degrees – it is the first concrete mixer that operates on a 360-degree basis.

All the machines have excellent manoeuverability and can get into small spaces, while the weighing system is integrated into the steering column – the operator has a running total in front of him at all times while raw materials are being loaded.

I also regard our exceptional after-sales services as something that sets the brand apart.

The company will supply an MD 485 tower crane, which is adaptable to a variety of job sites, due to its modular design and efficient load handling capabilities. In addition, its Optima controls provide for smooth speed changes and high productivity.

It will also supply a Potain MC 310 crane. The 25 t Potain MD 485 tower crane will pour the bulk of the concrete work at the Clanwilliam Dam, supplemented by the Potain MC 310 for smaller lifts.

Learning from the past The extensive experience that SA French gained at De Hoop will facilitate the construction process at Clanwilliam, and help drive down the overall cost for the client.

“The methodology of using tower cranes for dam construction is largely cast in stone, and a lot of the knowledge and experience we gained at De Hoop, and other DWS dams, will be easily transferrable to Clanwilliam,” says Quentin van Breda, managing director, SA French. A major accomplishment at De Hoop was relocating the Potain MD 485 tower on two separate occasions.

The company will have a team on-site for the commissioning process, while the DWS will use its own operators. “Part of our in-house offering is to train any certified operators that the client may require,” Van Breda says.

The company’s longstanding relationship with the DWS, starting with the former Department of Water Affairs on the Braam Raubenheimer Dam near Lydenburg in 1982, was cemented by its successful involvement at the De Hoop Dam. This relationship played a vital role in it securing its latest contract. “Our long-term relationships add additional value in terms of our comprehensive service and support,” Van Breda says.

Tower cranes and roller-compacted concrete Tower cranes are particularly suited to dam construction, as such projects require very specific lifts at certain radii. The number of lifts required on a dam site, in terms of piping, valves and pumps, does not justify the use of a crawler crane, from a cost-effectiveness perspective, Van Breda notes.

“More often than that, these lifts relate to the massive pipe structures that need to be handled and put in place. The only cranes that can handle these structures efficiently, in terms of the combination of the height and the required radius, are tower cranes,” Van Breda says.

ABOVE A Potain tower crane played an important material handling role in the construction of De Hoop Dam

The Clanwilliam Dam project is expected to use roller-compacted concrete (RCC), which the DWS pioneered at De Hoop. RCC is a far more cost-effective option than traditional concrete dam walls. It also allows for more compact and sophisticated spillway sections, which necessitates the use of tower cranes in these constrained construction sites.

T

HE PMR ARROW awards recognise and celebrate excellence in the local plant hire industr y.

Ever y year the benchmark is set at a new height, ensuring that this market sector continues to develop, expand, and improve.

PMR Africa conducts its annual national sur vey using a random sample of 100 respondents in the construction and mining industries who deal directly with plant hire companies.

Respondents are required to name the plant hire companies they have dealt with over the past year, list the type of equipment they hired and for what applications, and rate the respective plant hire companies on 18 attributes.

These include adherence to safety procedures/regulations; BEE compliance; quality, reliability, and condition of machinery; staff competence; and timeous completion of contracts. The survey is held in high regard due to the fact that it is totally independent and strongly end-user driven.

Bobcat Equipment Rental received the Diamond award in 2012 and 2014, and the Gold Arrow award in 2013.

Bobcat’s general manager: Rental, Wayne Smith, says, “This third Diamond award holds special significance for the Bobcat Rental team. When we received the 2014 Diamond award, we said it proved our ongoing commitment to delivering excellence in our products and service offering.

“Furthermore, we pledged to continue providing best-in-class compact equipment and deliver high-performance, reliable, efficient,

and cost-effective ser vice solutions for low cost of operation and ownership for customers and end users. And finally, we made a commitment to work even harder to ensure that we, once again, achieve top rankings in 2015. So, this award is irrefutable proof that we walk the talk.”

Smith extends a sincere thank you to valued customers and end users for, once again, placing Bobcat at the top of the Loader Rental categor y with a 4.15 out of a possible 5.00 rating.

“This award clearly signifies the ongoing credibility, respect, and recognition of the Bobcat brand among the captains of industr y.”

In acknowledging the important role of the Bobcat team in achieving this milestone, Smith says that this kind of achievement is only possible thanks to the unwavering support, dedication, and professionalism of the company’s skilled operators and sales, ser vice, technical, and administrative employees based at HQ, and at the countr ywide branch network.

Remanufacturing engines

W

HEN CUSTOMERS LOOK for engine remanufacturing services, they should audit the status and suitability of the remanufacturer’s equipment to determine if it is capable of machining these new-generation engines.

This is because new-generation engine components require far tighter machining tolerances and advanced machining methods during the remanufacturing process, Andrew Yorke, operations director at Metric Automotive Engineering, says.

The benefit of quality engine parts and skilled engineering is seldom seen in the first thousand hours of a vehicle’s operation. This only becomes evident later, when the engine starts to log extended machine hours. Coupled to this is the fact that modern engine designs are more complex than ever before in the quest to achieve improved fuel efficiency and higher emission standards.

“The engines currently being installed into new vehicles are highly sophisticated – not in their major elements, but in the minor components that are so critical to performance and emissions efficiencies,” Yorke notes.

“Although the primary elements have stayed the same, when it comes to engine rebuilding, machining and clearance tolerances have become a lot tighter.

“This necessitates far higher skill levels among remanufacturing engineers as well as more accurate equipment because there is less room for error.” Yorke points out that some fleet owners, plant managers, and foremen are unaware that the major engine OEMs share basic engine designs and simply adjust these to suit their own requirements.

“It cannot be assumed that because the engines look the same, the same parts can be used. “Metric Automotive Engineering's highly skilled in-house engineers understand

the latest-generation engines and have the knowledge to install correct parts that are of an appropriate standard. We are familiar with the subtle differences between engine variants, ensuring that the customer receives the correct parts first time round,” Yorke concludes.

ATERPILLAR’S MATERIAL handling, general purpose, and rock buckets are all available in heavyduty specifications. A standardequipped spill guard prevents possible spillage over the linkage.

Caterpillar also offers a wide range of special-application Performance Series buckets; applications include woodchip, high dump, and serrated edge.

Factors to consider when choosing the right bucket are the operational role, the material fragmentation type, the material, and the level of impact and abrasion.

“To ensure optimum performance, always match the bucket to the machine, based on material density and wheel-loader size,” explains Barloworld Equipment group product specialist Deon Delport.

Material handling Material handling buckets incorporate a flat floor design and are intended for loose material rehandling, making them well suited for a variety of stockpile loading applications. These buckets provide maximum

54

material retention and can be equipped with bolt-on adapters and segments, or bolt-on cutting edges with corner guards for versatility and longer life.

General purpose General purpose buckets incorporate a wedge floor design and are built with a shell tine construction to increase strength and rigidity in typical excavation and bank applications. The structure efficiently transmits cutting-edge loads back to the lift arms, shielding the bucket shell from distortion and keeping it up, out of the dirt.

For high-abrasion aggregate applications, heavy-duty general purpose buckets are the perfect choice.

Rock buckets Specifically designed for quarry, aggregates, and mining operations in high-impact and/ or high-abrasion applications, these buckets are factory modified with additional protection. Heavy-duty rock buckets feature larger GET and additional wear material for the toughest tasks.

An app revolution As technology advances, it influences and changes everything around us, and the infrastructure industry is no different.

BY LIESL FRANKSON

T

HE RECENTLY INTRODUCED variety of apps tailored to the industry ranges from sourcing construction vehicles and equipment, to ensuring municipal service delivery. All of these features and services are now available in the palm of your hand.

Service apps JRA Find and Fix app The Find and Fix app, developed by Intervate, was recently launched by the Johannesburg Road Agency. The purpose of the app is to simplify and enhance communication between road users and the JRA. The Find and Fix app enables the public to report potholes; faulty traffic signals, stormwater drains and manhole covers; and other infrastructure defects related to JRA. “The launch of this new smartphone app forms part of the JRA’s turnaround strategy and service delivery drive,” says Skhumbuzo Macozoma, JRA managing director.

Last year, the JRA launched a service delivery drive termed the ‘Just tell us’ campaign, which supported the city’s ‘active citizenry’ priority focus to promote citizens’ active involvement in the city’s service delivery activities.

The app – tagged as ‘snap it, send it, and we’ll fix it’ – is freely downloadable for most mobile operating system platforms. It provides an accurate location with GPS coordinates and makes it easy to provide photo evidence, which complements the JRA’s ability to plan repairs more scientifically, based on reports and data received, thereby enhancing efficiency and increasing productivity.

The app received top honours last year at the Microsoft Partner Network Awards 2014. This innovation from the city was the first of its kind in the countr y, continent, and the entire Southern Hemisphere.

The Find and Fix app was instrumental to Intervate in winning the Microsoft Application Development Partner of the Year Award, the Public Sector Industry Award, and the prestigious Managing Director’s Award.

Transport for Cape Town mobile app The City of Cape Town launched a mobile application last October. The Transport for Cape Town (TCT) app was the first of its kind on the continent to merge the timetables, stops, and stations of all the scheduled public transport services in a city.

The system maps all the scheduled public transport services across the city: the MyCiTi bus service, Metrorail, and the Golden Arrow Bus Service. These maps specify each service provider’s routes, stations, and stops.

According to the municipality, the app also tells commuters which mode – bus or rail, or combination of the two – to use to reach their destination, including: a list of options of the various transport service operators in their vicinity; where to find the closest and most convenient stops and stations; the distance to the stop or station; how to get there; departure times; arrival times; the estimated cumulative cost for the entire journey; and the estimated duration of the journey, inclusive of the time it will take to walk to a station or stop.

“We envision that the primary users of the app will be builders and paving contractors, although it should prove a useful tool, both in the office and on-site, for architects, quantity surveyors, and others working in the building industry.”

construction sector. It also keeps the user up to date with the latest news about the construction market and has a host of other useful features.

The Construction App contains information on portable energy products, road construction equipment, demolition and recycling equipment, concrete and compaction equipment, and service products.

The TCT app also enables those using private transport to plan their journeys by offering different route options – indicating the distance to the destination, the estimated travel time, and any matters of concern along the route such as accidents, roadworks, detours, and traffic delays.

The TCT app will enable users to report transport-related matters such as potholes, faulty traffic lights, flooding, accidents, and bad driver behaviour directly to the municipality. The exact location can be easily recorded

56

if the GPS is on, and the user will have the option of attaching a photo with a message to the municipality.

The Corobrik app Corobrik was one of the first building materials suppliers in South Africa to launch a dedicated app for the specification and application of its bricks and pavers. Available from iTunes, the comprehensive, interactive Corobrik app allows users to access the expertise of Corobrik at their fingertips.

The app features a brick matcher, notebook, pocket manual, weather forecast, store locator, and product gallery.

The brick matcher allows users access to a selection of Corobrik bricks and match them against a photograph of a brick they’ve seen and liked. The pocket manual is a wealth of technical expertise; users can choose

The manual is divided into the following seven sections, which feature answers to a comprehensive list of queries: • Section A: Foundations • Section B: Surface beds • Section C: Brickwork • Section D: Waterproofing • Section E: Clay paving • Section F: Site organisation • Section G: Compliance. Information for designing and specifying bricks in compliance with SANS 10400 Building Regulations and SANS 204 Energy Standards is set to follow.

The brick calculator also allows users to plan the quantity of bricks or pavers needed for a specific project. Not only will the brick calculator give an accurate estimation of how many bricks or pavers the project will need, it will also calculate the amount of sand and cement needed for the job as well.

Over and above this, the brick calculator will also determine how thick the plaster needs to be, and will revert with the

quantities of sand and cement needed to mix it to the correct consistency. Along with the weather forecaster, you’ll also find a handy flashlight and spirit level under the utilities section.

Peter Kidger, Corobrik’s director of marketing, says that using the available technology to make life easier and more efficient, in this day and age, makes a lot of sense.

“We envision that the primary users of the Corobrik app will be builders and paving contractors, although it should prove a useful tool, both in the office and on-site, for architects, quantity surveyors, and others working in the building industry,” he says.

The application also includes a tool that will advise on the best time of day to lay concrete or build, based on the weather forecast and conditions. This tool also allows professional master builders to list several locations, where they may monitor the weather conditions across all of their building sites, speeding up the decisionmaking process and prioritisation of jobs to be managed and completed.

Energy storage evolution

I

NTEREST IN ENERGY storage solutions from industrial-scale off-grid end customers and project developers is steadily increasing, according to energy experts THEnergy.

At the end of April, Tesla Motors launched its range of energy storage solutions. The company introduced the Powerpack – a solution for larger, industrial applications – for use in solar- or wind-diesel hybrid energy plants, as well as the Powerwall, a lithium ion battery intended for domestic use.

According to Bloomberg Business, Tesla took a staggering $800 million worth of Powerpack and Powerwall orders within the first week after launch.

The biggest impact on hybrid applications is of an indirect nature. Until now, the decision-making process for using hybrid solutions in an industrial context

was mainly focused on short-term pay-off periods. Storage solutions were often not even considered because they were notorious for being expensive, and the lack of awareness of competitive storage solutions often ended the purchase process before it even had begun.

The hype around the Tesla announcement draws additional attention towards all storage solutions and the company seemingly has a knack, in many cases, to create an awareness of storage solutions that was heretofore missing.

Through expert panels, THEnergy tracks energy-related developments in many

industries – from mining, tourism, food and agriculture, through IT/data centres and telecommunications.

“After Tesla’s storage introduction, we observed that more and more industrial and commercial end customers actively ask for information about energy storage solutions,” points out THEnergy founder Thomas Hillig.

Tesla Motors, founded and headed by South African-born Elon Musk, who also founded aerospace manufacturer SpaceX, has been a major driver and pioneer in the recent drive from combustion-engine to electric cars.

Growing support for IFAT
