BIMobject Awards 2016: Valsir between the best 7 in the world An interview to Eng. Nicola Zanca and Eng. Alessandro Giovannini We have interviewed Eng. Nicola Zanca and Eng. Alessandro Giovannini, Valsir technical directors and supervisors of the BIM development team, to talk about building design evolution and the opportunities for technicians. One of the most important suppliers of plumbing and heating systems on the worldwide market, Valsir has been selected as the most innovative Italian company in the development of 3D models by BIMobject®, the European portal for BIM objects management. Moreover Valsir has been selected to participate to the annual BIMobject Awards 2016: this important goal has awarded the right prize to Valsir continuous commitment in technological development and in never-ending research. Valsir is the only company of the plumbing and heating sector to be participating to the BIMobject LIVe 2016 in Malmö (Sweden) featuring 666 companies producing elements for architecture - from building to interior design - coming from all over the world, for a total amount of 50,000 parametric BIM objects. Now we ask Eng. Nicola Zanca to explain how technical design is being changed by BIM.

In your opinion, which technical innovations are changing the design techniques in the building sector? The future of design is tightly bound to the use of BIM (Building Information Modeling) technology which is becoming increasingly established as a new and innovative working method, in which the 3D digital representation of the whole building is shared by the all the design team members in order to make digital information exchange easier. Which are BIM main advantages? The first advantage is the real time visualisation of the building and of the development site with realistic planning scenarios. Another advantage is the drop in the mistakes made by the design team members: BIM allows the detection of interferences between parts and plants inside a building and the executions of modifications and reviews directly in the model, thus sensibly reducing costs bound to inprocess variances. Now we ask Eng. Alessandro Giovannini to explain which advantages are provided to designers using BIM technology.

How did you come into contact with BIM technology? For 30 years, Valsir has been operating in more than 90 markets worldwide and has established strong relationships with international design studios and building companies. In some countries, BIM is more widespread, and these experiences have allowed us to come into contact with BIM technology and to immediately catch its opportunities and advantages. Let’s talk about Valsir activity in the BIM sector: how long has Valsir been oriented in this direction? Valsir started developing its first BIM models in 2012 and, since the, has been constantly enlarging, updating and developing its families to the point of being able to complete the majority of the range of its products. Today our Revit® suite for the plumbing and heating sector has become the best now available on the market. The whole interview to Nicola Zanca and Alessandro Giovannini will be published on www.valsir.it

According to officials the project will open for flight testing of its recently expanded 3,000-metre runway that was initially measuring 1,400m. Once construction is complete, the Airport will handle large aircrafts like Airbus A300 to A380 and Boeing 747 to 787 The airport is expected to inject new life in the area’s economy and positively change the lives of local residents who have already benefited from services that came with the construction like accessing electricity good roads and decent housing. .This is one of the project that is being funded by the Kenyan government being implemented in Isiolo and it is expected to change the lives of the area residents. Since the project kicked off the area has been witnessing positive changes such as improved road networks, electricity connection and that is expected to double up once it will be launched. The airport is part of the Vision 2030 flagship projects and is expected to promote growth and unlock the economic potential of the region and the neighbouring pastoralist areas. The government also plans to build another airport in Embu County. The international airport will cost US$99mn and will be a collaboration between the county government and the national government. 6

Bio Therm Energy, an independent power producer has won a tender to develop a 20MW solar plant project in Ghana. The company will construct, operate and own the facility under a 20 year power purchase agreement. The project will be one of its kind at a utility scale for the West African country. The project is also expected to clear way for future developments in the renewable energy sector. The project will as well add the needed power to the Ghana’s national grid where power interruptions are frequent and create employment opportunities for members of the local community. Recently, Bio Therm secured 284 MW of wind and solar projects in South Africa and 34MW of solar projects in Burkina Faso. According to Jasandra Nyker, Bio Therm Energy CEO, the company is growing from strength to strength and the recent contract award marks a significant milestone achievement for the company. The company is looking forward to concluding the necessary agreements with the government of Ghana. Ghana’s main power generator, the Volta River Authority (VRA), had projected about US$1.5bn to improve the country’s power generation, while President John Dramani Mahama indicated the country required to generate at least 220MW of power every year.

Kenya banks on sell of 15-year bond to boost infrastructure

Kenya seeks to raise US$296mn from the domestic market for infrastructure projects in the energy, water and transport sectors through the sell of 15-year infrastructure bond. The country’s Central Bank says this will be achieved by selling a 15-year infrastructure bond to raise funds to boost infrastructure in the country. Kenya is carrying out a number of infrastructure projects that include construction of power plants and bypasses funded by both donors and the government. Already an estimated Sh5.56tn (US$54.8bn) investment into infrastructure development for Kenya is planned, the majority of which will focus on telecommunications and power generation infrastructure. Despite having made significant progress in infrastructure development in recent years, the country’s infrastructure indicators remain below the levels found in Africa’s middle-income economies, like Egypt and Nigeria. Analysts say bringing Kenya’s infrastructure up to the level of the region’s middle-income countries could boost annual growth by more than three percentage points. This will be a major boost to Kenya’s transport sector that has been in the past few months on the rising as the government seeks to have more projects done. The government of Kenya seems to be committed towards improving the infrastructure sector as that remains their key selling point.

Kenya Kenya’s Lapsset project receives new breath of life The Lamu Port South Sudan Ethiopia transport corridor (Lapsset) project has received a major impetus after a consortium of international investors led by the Development Bank of South Africa (DBSA) said that they will help finance the project. According to State House the consortium has already agreed to inject over US$1.9bn into the project. This is going to be a great boost to the project as recently it had slowed its momentum due to insufficient funding and the investors are interested in putting up three berths at the Lamu Port and financing the construction of the 537-kilometre LamuGarissa-Isiolo road. According to the State House spokesman Manoah Esipisu both the Kenyan government and the South African have signed an MoU on the Sh2.5tn (US$24.66bn) project during the visit by President Jacob Zuma. He said that the visit of President Zuma to Kenya was beneficial and they expect more development to be announced in the next few weeks. The DBSA is wholly owned by the South African government, and has arranged funding for projects in transport, energy, water and ICT sectors. The Lapsset project, which was commissioned by former President Mwai Kibaki in 2012, is expected to open up Kenya’s northern frontier for more trade and investment, and has been identified as the long term conduit for Kenya’s oil exports through a crude pipeline linking Lamu to the oilfields in Turkana County. The project has been hit by delays due to financial problems after several financing countries withdrew. December 2016 - January 2017

New Seifsa president urges employer proactivity ahead of 2017 wage talks The incoming president of the Steel and Engineering Industries Federation of Southern Africa (Seifsa), Michael Pimstein, has appealed to employers affiliated to the organisation to adopt proactive actions towards the upcoming wage negotiations in 2017. Pimstein is returning back to a Seifsa position he held in 2006 and 2007, after Angela Dick, of Transman, who was elected as the association’s first woman president in October 2015 resigned. Previously, he led Macsteel Service Centres South Africa and is currently joint CEO of Capital Appreciation Limited, which invests in businesses across various sectors. In a recent address to Seifsa members, Pimstein called for urgent discussions with the labour unions in the metals and engineering sector and appealed to employers to embrace dialogue. During the previous round of wage negotiations that took place in 2014, a three-year settlement was secured after a month-long strike that sometimes turned violent and will expire at end of June 2017. The 2014 to 2017 agreement was also strongly opposed by rivals of Seifsa, the National Employers’ Association of South Africa (Neasa), which termed the settlement as “unaffordable” for smaller firms in the metals sector.

Intel launches its own drone, designed for industrial jobs Intel has unveiled its first fully Intel-branded drone, dubbed the Falcon 8+ designed for industrial jobs for instance big construction sites where it might take a human hours to walk around to complete a field inspection. The Falcon 8+ weighs only 2.7kg and flies faster than most hobby drones on the market, able to reach speeds of up to 35 miles per hour. This isn’t Intel’s first foray into drones. The company partnered with Ascending Technologies, which it later acquired, to refine its 360-degree depth-perception cameras for collision avoidance. The cameras are now used in the commercial AscTec Falcon 8, the predecessor to Intel’s 8+, as well as Yuneec’s Typhoon H drone, which is also intended for commercial or professional hobbyist drone pilots. The drone is controlled with a waterproof cockpit equipped with a joystick and tablet, which is much more robust than consumer drones that interface with smartphones. Unlike with hobbyist drones, where DJI already accounts for 70% of the market, the commercial and industrial drone scene doesn’t yet have a single dominant drone maker. 3DR, which once touted itself as the leading drone company in the U.S., is now completely switching to building drones for commercial applications. And other drone makers, like Yuneec, Kespry and DJI, all have commercial-grade offerings, too.

OPINION

Capital risk hampering growth of renewable energy sector Tina Nduta, Managing Director - Eimara Africa Resources.

Renewable energy in Kenya

K

According to the World Bank, Africa’s private investment in the energy sector is about one per cent, compared with 34% in South Asia, 26%in Latin America and 25% in Eastern Europe and Central Asia. 12

enya was recently recognized as one of the most attractive renewable energy markets in the world. The country was ranked as one of the fastest growing markets for renewable energy by Ernst & Young’s Renewable Energy Countries Attractiveness Index (Recai). The report put Kenya’s renewable energy sector in the Rising Star category, which comprises promising growth markets. This comes against the backdrop of the COP21 Paris Agreement that set to create a US$13.5tn global low carbon investment market by 2030. Ahead of the COP21 Convention, Kenya pledged to cut its carbon emissions by 30%by 2030. With geothermal energy sources, wind speeds averaging 11m/s — one of the fastest in Africa — and receiving sunshine all year round due to its location on the Equator, Kenya is a potentially prime renewable energy producer. But legal disputes, security and legislation and confused policies seem to pose significant hurdles to investors in the sector. The collapse of the 60MW Kinangop Wind Park has, for example, cast a dark shadow over the sector. The compensation dispute after the project’s licence was withdrawn following protests by the local community over land acquisition, has taken the firm and the Kenya government to the International Court of Arbitration. The firm is seeking compensation on an indemnity that the Ministry of Energy had

promised in the event that the project failed to take off. Last year, US-based Walam Energy sued the county government of Turkana for the cancellation of the licence of independent geothermal exploration company Olsuswa Energy following a land dispute. Around the same period, a Russian firm OJSC sued KenGen for allegedly favouring a rival company in a US$140mn tender award. These disputes are worrying. The mining sector is also facing similar challenges. Last year, Canadian gold explorer African Queen Mines withdrew from Kenya, citing security concerns. The other factor that may adversely affect the renewable energy sector is the new Companies Act, which could make it mandatory for foreign investors to cede a 30% stake in their businesses to local investors. Energy projects usually involve large capital investments and the requirement may make it hard for local investors to find foreign partners. Private capital Private institutional investors in Kenya rarely want to go into energy development because of the capital risk. One of the reasons why the African continent has the least electricity penetration in the world despite having the largest energy reserves — especially in renewable energy — is because its energy sector has the lowest private capital participation. The result is that over half a billion people on the continent do not have electricity. December 2016 - January 2017


According to the World Bank, Africa’s private investment in the energy sector is about one per cent, compared with 34% in South Asia, 26%in Latin America and 25% in Eastern Europe and Central Asia. This is attributable to policy and investment risks that undermine efforts to attract capital. In addition to the power deficit, power cuts in subSaharan Africa also hamper growth. The World Bank estimates that blackouts alone cost countries up to 2.1%of GDP. In Kenya, over half of the population does not have access to electricity, even as the government rolls out ambitious energy projects to generate and provide sustainable and affordable electricity. But the Kenyan energy projects are left almost entirely to the government and foreign investors. The International Monetary Fund has already warned Kenya against overexposure to debt in power deals, saying that Nairobi has guarantees on up to 12 power purchasing contracts worth over US$3.43bn , or 5.7 per cent of GDP, that have not been made public or accounted for. Private-public partnerships are critically important for Kenya’s energy and energy infrastructure development if the country is to meet its targets. Equally important is Kenya’s ability to provide security

MANAGEMENT

Reasons why you should invest in construction estimating software

M

any firms in Africa are heavily investing in the Construction estimating software, or software designed to forecast costs on a specific project with hopes of saving money and time., But the reality is that construction estimating software can provide so much more than its surface-level features. Why? 1.

Construction estimating software thinks lean When you think it’s hard to give an approximation on what a project will cost and how much profit you will make therefore this is the best decision to make. Some software help to get rid of elements that are “not essential to the success of the business and as a result has created streamlined workflows for greater efficiency and effectiveness.” 2.

Forget the hassle of materials estimating So much of the estimating process relies on subcontractors—construction firms are constantly trying to figure out how much do they charge for labor and materials. Thankfully, construction estimating software rids the industry of disparate spreadsheets and timeconsuming cost-estimates. For example, Plexxis Software 14

specializes in streamlining common construction materials for subcontractors and contractors alike This process makes it easy for subcontractors to figure out the exact quantities they need—eliminating waste and duplicated estimation work. 3.

Add extra value to your estimates

With the construction estimating software your firm will be able to add value to your construction estimations and hence this will make your firm more attractive to the clients. The best example is that with the software the contractors can use construction estimating software to point to areas that would add long-term value to the home instead of short-term and costly renovations. 4.

Save money. A lot of it

According to Capterra’s own research, construction estimating software comes with quite a range of features. While some might choose construction management software with estimating as a feature, others might want to hone in on a software option that exclusively does estimates and bidding.

COVERSTORY

Cement Production Competing for Africa’s market

I

By Anthony Kiganda n the wake of enhanced activity in infrastructure projects and a booming real estate development market in Africa, cement producers on the continent are racing against time to meet the ever increasing demand of the construction commodity which by some estimates stands at about 30 million metric tonnes and growing. Even in South Africa where the slump in the extractive industry has severely affected the economy, Pretoria Portland Cement (PPC) Limited, the largest cement maker in the country reported that consumption of cement in the country rose by 7.7 per cent in 2015 recovering from a major slump in 2014. PPC attributes the growth to construction projects of new power stations and hydroelectric plants in the country. Notably, demand for cement in Egypt is picking up after the Arab spring stagnated the industry. While releasing its financial report for first half 2016, main cement producer in Egypt Suez Cement Group of Companies (SCGC) reported growth in sales; mainly driven by mega infrastructure projects in the country. In West Africa, Nigeria’s per capita consumption of the commodity remains relatively low compared to Asian and European countries a fact that is true for the rest of Africa. Lafarge in Nigeria has been facing choppy waters as a price war with Dangote Cement has seen market share as well as price margins eroded significantly. 16

Dangote reported having sharply increased volumes by 38 percent, though this has been at the expense of its bottom line; forcing it to review its expansion plans in the medium term. But it is in Eastern Africa that many of the major players are focusing their attention and hoping to increase market share. This is a region where cement plants are coming up in Ethiopia, DRC, Rwanda, Kenya and Tanzania Rising demand in East Africa According to the latest report by Ecobank, East Africa is fast becoming a new frontier for cement makers. This is supported by infrastructure development projects and new construction business opportunities, as the region’s growing middle class spurs demand for local service delivery. Kenya for instance is constructing a US$13 billion railway that will link the port of Mombasa to the Rwandan capital of Kigali via Uganda. Ethiopia on the other hand is building US$4 billion hydro-power dam on the Blue Nile River. The country is also constructing what would be the tallest building in the region backed by Commercial Bank of Ethiopia at a cost of USD $270m. Recently, Ethiopia became the first subSaharan African country to have a light railway system, when it unveiled the Addis Ababa electrified light railway network. Additionally, it launched the 750km railway line connecting the country and Djibouti. Uganda is currently enhancing its power

production by building new hydro-dams such as the 600MW Karuma hydro power project, 183.2MW Isimba hydroelectric power project as well as the 600MW Ayago hydro power project. Other hydro-power projects that the country is constructing include, Nyagak III and the 44.7MW Muzizi hydro power plant. These projects alongside the construction of roads, housing and port developments have essentially fuelled demand for cement in the region. In Kenya for instance, cement production crossed the six million tonnes mark in 2015. Data from the Kenya bureau of statistics (KNBS) shows that manufacturers produced 6.3 tonnes in 2015 up from 5.8 million tonnes in 2014. Ecobank’s report shows that with the prevailing boom in construction activities in the region coupled with strong Gross Domestic Product, investors are bullish when it comes to the African cement market. East Africa is now considered to be one of the world’s fastestgrowing marketplaces for construction opportunities and building materials. Stiff competition But who are the players and where are their footprints and spheres of influence? PPC has set its sights on Ethiopia where prospects are high amid tough competition in its home soil. The Ethiopian market is fast becoming important not only to PPC but also other investors because of its promising economic growth. The country is currently growing at the rate of 11% per year. December 2016 - January 2017


Indeed, South African cement maker PPC’s financial report reinforces this report. While presenting its financial report for six months ending March 31 2016, PPC announced that Rwandan cement maker Cimerwa Ltd helped to cushion its revenue. The Johannesburg Stock Exchange-listed company has a 51 per cent stake in Cimerwa Ltd. PPC plans to increase its production by as match as 75 percent and already has 4 projects underway in Zimbabwe, Rwanda, Ethiopia and DRC. PPC is targeting 40 percent of sales outside South Africa by 2017. The company has also acquired a 40 percent stake in a new plant in Algeria with a 2 million tonne capacity. Nigerian cement maker Dangote opened a plant in Ethiopia in 2015 to boost construction activities in the country. Mid this year, the firm started exporting the product to Kenya from Ethiopia stirring the market that is already grappling with tough competition. In a bid to tap demand in the region, Dangote also has a footprint in Tanzania. The factory there started production this year with cement prices falling by a third in the half year. Aliko Dangote is reported of proudly stating that his company crashes the price of cement in every market it enters on the continent. Working on economies of scale to set lower prices and grow its market share, Dangote cement’s ultimate goal seems to topple LafargeHolcim which is currently the largest producer of cement in Africa. In Kenya where demand for cement is on a rising trend, producers are on the expansion mode too in a bid to match demand. In 2014, Kenyan ARM Cement Company completed the construction of a clinker plant in Tanga Tanzania, which boasts an annual capacity Company

Demand for cement in East Africa has also attracted foreign manufacturers who are now supplying cheap imports from countries such as China and Pakistan

of 1.2m tonnes. Recently, the Nairobi Stock Securities-listed cement maker announced that it was expecting financial support from British government-owned fund CDC Group to set up a new clinker and cement plant in Kitui County. Early this year, Mombasa Cement unveiled plans to build two new cement factories and triple its output at a cost of US$73 million. The objective of the expansion of Mombasa Cement is to increase the current clinker production capacity from 3,000 tonnes to 9,000 tonnes per day and that of cement. Central Africa that has long been supplied by East African suppliers has come into the spotlight in the Democratic Republic of Congo (DRC) where a Pakistani company Lucky Cement has completed a 1.2mt/yr cement plant while PPC has also done the same with a 1mt/yr plant. Cheap imports Demand for cement in East Africa has also attracted foreign manufacturers who are now supplying cheap imports from countries such as China and Pakistan. The cheap imports are already weighing on prices and threatening

Production capacity

profits for African producers in Tanzania and even South Africa. The situation became so bad that in 2015 HeidelbergCement AG shut down about a quarter of plant capacity at its Tanzanian unit due to oversupply and lower prices partly caused by cheaper imports from China and Pakistan. “With the current oversupply our business is not viable in the medium term, we may be forced to restructure our human resources,” said the Managing director Alfonso Rodriguez at the time. Kenya on the other hand has been grappling with importation of cement from China. Data presented by KNBS this year reveals that US$22m worth of cement was imported to Kenya in the first six months of the year. Last year, Kenyan cement producers expressed concerns that they were being left out of a $3.8-billion railway project that China Road & Bridge Corp. was building, after the company gave an assurance it would source all of the materials domestically. This they argued could kill the local industry and diminish job creation. ...Continued on page 33

GEOMEMBRANES

GEOMEMBRANES The essential application for fluid or gas containment

G

eomembranes are the most preferable waterproofing elements in civil engineering used to minimize fluid or gas movement. Geomembranes are commonly used together with other geosynthetics such as geotextiles, geo clay liners, or geonets among many others. Geomembranes can be made of polymers, asphalts or rubbers and can have a smooth or a rough surface. They can be black or colored for technical or visual reasons; they can even be conductive to help detect eventual leaks or reinforced to give more mechanical stability. Geomembranes are thermoplastics which means they can be modified by heat action.. Others are thermos tables which means the fusion and welding is not possible by the nature of the product. EPDM for example can be assembled through a method called vulcanization; that is the application of a strip with very special glue. Examples of polymer-based membranes are Polyethylene, Polypropylene and Polyvinylchloride (PVC). PVC has been used widely in the last decades, but the introduction of the plasticizer to its composition increased its flexibility and made end users opt for polyolefin-based membranes like HDPE, LLDPE and PP. The raw materials for manufacturing these products are refined by big petrochemicals and are very well structured chains of carbons, with very special characteristics. They are added antioxidants (to avoid the burning of the material during manufacturing and its later use in its utility life) and additives to protect the product from the Ultraviolet (UV) radiation. The most common protection is the carbon black, which confers the typical black color of the exposed

geomembranes and it is the one which gives better results. Some traditionally used geomembranes like PVC need the help of plasticizers to increase their flexibility, but these can migrate with time. The most used in terms of quantity at worldwide level is the Polyethylene. In the waste industry particularly the HDPE, it is used because of its chemical resistance and for being a barrier not just for liquids but for gas too. This is used as the main barrier in landfill sites and safe containment applications. LLDPE is also used for the capping of waste disposal sites. Choosing the right geomembrane Think first on the durability of the job, if it is to last for the next 6 months or the next 50 years and think of the materials it’s going to be in contact with. The physical stress that the geomembranes are going to suffer from can easily be calculated during the design period. But, the chemical aggression that can bear the geomembrane will be the real attack we have to be prepare against. For example HDPE, the most commonly used membrane worldwide for the waste safe containment applications and also for water impoundments. The durability of this kind of geomembrane is directly linked to very simple factors: the determination of the raw material, we can find very advanced resins that have extremely good behavior at long term and during the transformation. The percentage of the pure raw material there is used while preparing the geomembrane, the purest proportion, the best results in terms of lifespan, and the quality and quantity of the additives as antioxidants and UV protectors. It exists a wide normative either December 2016 - January 2017


When looking for the right geomembrane think first on the durability of the job, if it is for the next 6 months or for the next 50 years

locally or internationally to determinate the results that a geomembrane should achieve considering "apt". But, the industry is advancing more than this normativization, and resins and manufacturers are ready for more strict results. Example of this is the stress cracking that makes the crystalline structure of the HDPE geomembrane to break in presence of chemically aggressive solutions and mechanical stress. The most commonly used norm for measuring this, is the ASTM D5397. The international standards set the apt result in 500 hours, but we can find in the industry geomembranes with 3000h. Temperatures are also potentially dangerous to the geomembranes as they accelerate the catalyzing of the losses of antioxidants. The higher the temperature, the higher the degradation it will suffer and the durability compromised. Many tests have been designed to extrapolate exposed conditions to a lab: UV radiation lamp exposures, high temperatures oven exposition, simulation of leachate, etc. The conclusion would be to ask at any time the best possible manufactured membrane2 that11/11/16 the af_atarfil_revista_africa_180_65.pdf technology allows us, provided the current state of the art.

Performance of the African markets A number of international companies have made strong entries into the African market. Atarfil is focusing its efforts in Africa, contributing to the sustainability and ensuring a higher level of security in all projects. Their philosophy is very clear, they have a unique and global product, with the best possible technology at the moment, for producing geomembranes in terms of regularity and consistency (calendared system) and transforming the most advanced and selected resins; for having very well balanced geomembranes that are conceived for extreme conditions of temperatures and UV radiation typical in the African continent. To have unique products means that exactly the same geomembrane is delivered to the landfill of a European capital than to an African small village waste disposal site. The need for environmental protection and the right to health is unique and global, and must not 14:50 depend on the available budget.

ADVERTISERS MESSAGE

Precast production plant of Weiler GmbH at Stroyindustria in Russia

With its Weiler plant, Stroyindustria has already signed a contract for over 12,000 pieces of foundation piles (total 130,000 linear meters).

The first precast concrete products were manufactured and delivered in the middle of 2016.

Weiler GmbH Established in 1954, the German family-owned business Weiler GmbH is one of the world’s leading companies providing advanced precast plant engineering services and factory production machinery for producers of precast concrete around the world. Precast production plant with modular concept for Stroyindustria in Russia

A

fter signing the contract in spring 2015, the last trucks with machines were unloaded at the end of the same year. After a short winter break, the plant was set up and put into operation by June 2016. The first precast concrete products were able to be delivered to the Russian market. Matthias Holzberger emphasizes: “The modular concept of the weiler MAX-truder® is perfectly suitable for such a project, because one machine can produce hollow core panels for floors up to more than 40 cm high as well as for walls with a thickness between 8 and 15 cm. Therefore, combined with the weiler MULTI-caster®, we planned to produce, aside from the pre-stressed hollow core panels, the pre-stressed foundation piles and lintels which were all new to the Russian market. Another new and special feature is the production of pre-stressed wall panels from lightweight concrete.”

The new Weiler management team & owners Matthias Holzberger, 32 years incl. experience, CEO, Sebastian Holzberger, engineer at Weiler for 6 years, CEO, Christine Bootz, at Weiler for 21 years, authorized signatory, Rebecca Holzberger, at Weiler for 6 years, marketing & sales communication

From planning to implementation: All from one source! Apart from the bed production line, reinforced concrete columns and beams are produced with a twin-mould system as well as precast concrete stairs with an adjustable stair mould. The plant is completed by a Weiler concrete batching plant as well as an automatic bucket conveyor and concrete distributor. Of course, the most important Weiler machines have a remote maintenance system. This unique feature allows the Weiler service team to provide real-time support to client production operations via direct Wi-Fi links to key equipment. The Samara plant produces up to 175 m³ precast concrete products per day on five production lines. Due to the special compaction method of the Weiler machines, almost 7,000 tons of cement can be saved yearly as opposed to former production processes. This corresponds to saving approx. 500,000 € (36 Mio. Rubles).

With its Weiler plant, Stroyindustria has already signed a contract for over 12,000 pieces of foundation piles (total 130,000 linear meters). Those approx. 16.000 m³ of concrete are produced by the weiler MULTIcaster® in only 90 days. “The younger and dynamic generation introduced many modern technologies and innovations in our company during the last eight years and is now ready to take more responsibility. Tightly organized, efficient, innovative and future-oriented – that is the new face of Weiler today”, says Matthias Holzberger. Therefore, the family business switches to future-orientation and integrates the next generation into the management team. This includes: his son Sebastian Holzberger (28, mechanical engineer, 2nd CEO and Head of Research and Development), his daughter Rebecca Holzberger (26, marketing and sales communication), and Christine Bootz (51, authorized signatory and head of human resources and accounting/controlling). These directors are also shareholders of the company. The family business will continue to provide an integrated concept for its customers, which includes combining more IT solutions with the newest engineering technology. In addition to this orientation, the existing core competencies and longstanding experience shape the new Weiler 4.0. In doing so, it will remain faithful to its philosophy and principles: To read more and to comment on this story visit

WATERPROOFING

vary widely in quality their performance can extend from excellent to poor. Brian adds that one should purchase only reputable international brands and check the product datasheet for the intended use. In general the higher the polymer content the better the quality. This is relatively easy to assess as the products are usually supplied in two components a liquid polymer and a cement based powder. A general purpose product will have 5 liters of polymer to 20kg of powder while high performance product will have 10 liters of polymer to 15 to 20 kg of powder. But remember unscrupulous brands will dilute the polymers with water so play safe and buy from reputable international brands.

Concrete Waterproofing Sealing the leaks

W

By Lubwa Leonard ith the growing emphasis on the use of eco-friendly building products in Africa, there has been strong local interest in concrete waterproofing products in the African market. Many people in Africa however believe that installation of ceramic tiles can offer the required protection. This is partially but not fully correct. It is true that tiles are tight enough to block the passage of water but expecting the objective to be completely solved by tiles would be wishful. Even the tiniest crack in the tiles or the joints in between can allow the passage of water. To fully protect a structure from such water ingress and to prevent corrosion of the steel reinforcement, the best solution is waterproofing. For any building there is a strong need to protect it from excess and uncontrolled inflow and absorption of water especially the structure’s foundation. The foundation is literally what the house is built on, what keeps the building where it was built, transferring the dead loads and the live loads into the ground. The source of the vast majority of foundation problems is water. Wet soil beneath a foundation can swell or lose strength. This significantly compromises the strength of the structure. Then there is the little problem of wet damp basements 24

and crawl spaces that can breed mold and make below-ground interior spaces generally unpleasant. Keeping water drained away from concrete foundations and preventing it from moving through the concrete are essential to a successful structure. Concrete Waterproofing Products There are many substandard waterproofing products in the market in Africa today. Different products can also have very different characteristics hence there is need for careful evaluation so as to ascertain the correct product to apply. It is better to play safe and buy products from international brands such as X-Calibur, Sika and BASF all whom are present and manufacturing in Kenya Cementitious Waterproofing Cementitious products are probably the easiest waterproofing materials to use. They are readily available from suppliers of masonry products, and they are easy to mix and apply. In applying these types of material, a longhandled brush makes the work easier. Brian Davies, Managing Director of X-Calibur an American construction technology company, says in order to get the required bonding and more solid coating, use a bonding agent on the concrete substrate to ensure maximum bond. Brian adds that because these products

Crystalline Membranes Crystalline waterproofing membranes are very effective surface applied products that bond integrally with the concrete to block all the porous pores in concrete and cracks up to 0.4mm wide. They are very cost effective and ideal for use in water tanks, lift pits, sumps manholes etc. However they are not suitable for use on roofs, under tiles or coatings despite claims from some manufacturers. Liquid Ready to Use Membranes The liquid membranes are applied by spray, roller, or trowel. The liquid cures into a rubber like coating on the wall. Some sprayapplied liquid membranes are composed of polymer-modified bitumen while others come in form of polyurethane liquid membranes. The bitumen based membranes are normally used for damproofing and concrete protection beneath ground. The polyurethane membranes have extremely high performance and should be used in critical areas such as roofs or terraces. Liquid coatings have the advantages of speedy application, low in-place cost, and excellent elongation. One of the chief shortcomings however is the possible inconsistency in coverage. The typical application thickness is 1.5mm, but it takes a careful applicator to be sure of always achieving that minimum coverage. Again, use a reputable applicator certified by one of the international brands and this problem is mitigated. Be sure to have the warranty issued jointly by the product manufacturer, this applies to all waterproofing. December 2016 - January 2017


Self-Adhesive Sheet Membranes The most commonly specified sheet materials are selfadhering rubberized asphalt membranes. These 1.5 to 2mm thick membranes are composed of rubberized asphalt laminated to a waterproof polyethylene film. They are considered the ‘Rolls Royce’ of waterproofing materials. The asphalt side is incredibly sticky but is covered by a release paper, which you remove during application. These membranes must be installed by a professional reputable applicator. Before applying one is also advised to seek more information on surface preparation, priming, patching, joint treatment, terminations, lap joints, penetrations, and corners. Because they are so sticky, these membranes can be pretty unforgiving. Once a piece is down, you won't get it back up again at least not in reusable condition. However, the system allows easy repairs of holes, fishmouths, puckers, and wrinkles. You'll patch holes or damaged areas with a piece of membrane placed right over the first layer. With a fish-mouth or wrinkle, all you do is slit the raised area, press it down flat, and cover it with a patch. A chief advantage of sheet membranes is their consistent thickness. Because they're manufactured to exacting tolerances, you can be sure of the 1.5 to 2.0 mm coverage. These membranes also have good elongation. A higher in-place cost is one of the main disadvantages of sheets. The cost of the material itself is likely to be greater on a square-foot basis than the liquid membranes. Labor cost is also higher, because of all the cutting, handling, reinforcing, and detailing you have to go through during installation. Brian says

that you will not have a leak for 20 years plus if installed correctly. X-Calibur one of the international brands present is offering a 20 year warranty on these systems. Torch on Bitumen Sheet Membranes Brian says bitumen is widely used throughout East Africa these systems comprise of highly filled bitumen to produce a 4mm sheet usually referred to as APP membranes. While they are cheap they are tedious to apply and nearly every project faces problems. They have to be applied to a bitumen primed surface. Application is by using a face to torch the underside of the sheet to melt the bitumen then roll it out and then use a heavy roller to ensure air bubbles are removed and it sticks to the primer. Application is rarely done correctly leading to the Achilles heel of this system water penetrates usually through poor lap joints and travels under the membrane. When a leak is detected you don’t know where the water came from and this leads to massive problems once the building is operational. Brian says he has never seen a correct installation in Kenya.

cold, trowel-grade dampproofing and reinforcing fabric. Again, this system has some strength but little elasticity. Bentonite Sheets Sodium bentonite, a clay material, has enjoyed a steady upsurge in popularity over the past several years. Bentonite works because it can absorb a tremendous amount of water. As it takes in water, the clay swells to 15 times its original volume and pushes itself into cracks and voids. When it reaches its maximum volume, it stays in these areas permanently to seal against water. Some waterproofers are however afraid of using bentonite panels. With other products, you can inspect the finished waterproofing application and confirm the integrity of the seal before backfilling. With bentonite

panels, the seal doesn't form until the foundation is backfilled and water reaches the panel. Bentonite has its advantages, however: It's safe to work with, non-polluting, easy and quick to apply, and can go on even at low temperatures. Waterstops Waterstops are used as the first line of defense in waterproofing they should be used in all construction and expansion joints. They are PVC profiles that are cast into the concrete during construction to form a permanent barrier. For construction joints a new technology has emerged; this is the hydrophilic water stops. These are swellable strips that expand in the presence of water forming a permanent seal. They are very easy to install and are used on many prestigious projects worldwide.

Built-up Systems By using these old technology systems, a primer is first applied. You then mop on a coating of hot tar, heated in a large asphalt kettle, followed immediately by application of a sheet of perforated felt, extending the system right out onto the footing. You keep staggering the felt sheets until you have three layers of felt with a final coating of tar. This is a good system with a lot of strength, but probably not much elongation ability. You can produce a similar builtup waterproofing system using

Ghana Needs Large-scale Foreign Investment to Increase its Transmission Capacity

ncorporated on December 15, 2006 as a private limited liability company under the Companies Code, 1963, Act 179 and granted a certificate to commence business on December 18, 2006; GRIDCo was established in accordance with the Energy Commission Act, 1997 (Act 541) and the Volta River Development (Amendment) Act, 2005 Act 692, which provides for the establishment and exclusive operation of the National Interconnected Transmission System by an independent Utility and the separation of the transmission functions of the Volta River Authority (VRA) from its other activities within the framework of the Power Sector Reforms. The company became operational on August 1, 2008 following the transfer of the core staff and power transmission assets from VRA to GRIDCo. However, Ghana’s electricity penetration is among the highest in the region. That has come as a result of policies adopted by the Ghanaian government, especially rural electrification. The demand for electricity in Ghana grows about 12% every year, meaning at least 200 additional megawatts are required every year. Ghana is a developing country and cannot add the 200MW of power on its own. That calls for large-scale foreign investment.

In addition to this, Ghana is linked to other countries in the region by the West Africa Power Pool such as Ivory Coast and, by extension, Burkina Faso. On the other side, the country is linked to Togo and Benin. There are technical problems that impede the nation from linking with Nigeria, but it will eventually. If you invest in Ghana, you have the potential to export power to any part of the sub-region. Ghana is the destination for power investment. Disruption in the supply has a hugely detrimental impact on the country given that there are certain power plants in Ghana that run on gas only resulting to so many competitors for Nigerian gas. Once the gas is available from Ghana, the nation will allocate it directly to its power plants, especially in the western region. Gas production will also generate savings, because of decreased fuel costs. With these savings, Ghana can improve its systems, as gas, generators will last longer, as they will be needed less, so maintenance costs will go down. For many reasons, Ghana Gas will be very good for Ghana. Nevertheless, Ghana is not going to be without the need of the Nigerian gas completely. Not all the plants in Ghana can be supplied fully by Ghana gas, especially December 2016 - January 2017


because Ghana will have additional generation in the years ahead. In the meantime, Ghana has received commitments for an additional 2,000MW from many people who want to set up new power plants in the western region. Ghana gas will not be enough for that and the nation hopes there will be bigger finds. So Ghanaians will still be dependent on Nigerian gas. However, Ghana gas will ensure that some of the plants will always be on. Once that is done, it will be easy to build hydro resources, because once you have gas supplies, you don’t drain the dams too much, so it will help the country save water. As part of this, the Electricity Company of Ghana is supposed to settle all its debts. We are going to capitalize on that. Once we are able to get all the money we are owed by the ECG, we will use that to invest in the major projects we have lined up. Between Tema and Accra we have a number of overloaded lines. “We will use this money to ensure we have a more robust system. We want to ensure that when there is new power generation, we are able to transmit it efficiently and effectively straight away. We don’t want a situation where new power plants are ready but our facilities are not. We are trying to get money from everywhere to ensure we expand the system to meet increased supply and demand. We definitely need 200 extra megawatts every year, as I said earlier. One aspect of our power generation is that we have a large hydro-based portion. This is not always reliable, as rainfall can change. Sometimes we expect inflows into the system that don’t come. Assuming hydro can fail, you must follow other strategies. As part of the plan, we are looking at the type of generators in use and the correspondent fuel usage. That is very key for us. We are also interested in renewables, like solar. Two companies have interacted with us, wanting to do very large solar projects. There should be some concrete announcements on one of these projects soon. At GRIDCo, we consider solar as reliable power storage for hydro. During the day, you can use the solar, and save water from hydro. That is why we are amenable for solar to coming into the system. When solar investors approach us, we conduct a grid impact study, to see what the benefits will be for our system. We think the benefits of solar for our country are potentially very big and we welcome interests in this area. We have interacted with a number of British companies over the years in consulting and construction. In fact, some British companies are currently constructing some new substations and lines for us. We like the quality they bring to us as a country and as a company,” explained Mr. William Amuna, Chief Executive Officer GRIDCo, Ghana. GRIDCo never existed until 2008. It was the transmissions department in the Volta River Authority before then. Mr. Amuna is one of the most experienced transmission engineers in Ghana. He has worked as an assistant engineer, senior engineer, principal engineer, and manager; then moved to director of technical services. He has worked in the grid system 80% of his working life. He used to be a commission engineer. All the sub-stations that were built from 1989 to 2005, he was the commission engineer, so he is well versed in the grid system. December 2016 - January 2017

BUILDING PROJECT

Southfield Mall to Offer More Shopping and Leisure Choices for Embakasi and Surrounding Area Residents The Concept The proposed development is situated in a highly visible site along Airport North Road which is a major corridor connecting Mombasa road to the rest of Embakasi area. The South Field mall is at the center of the industrial and residential hub and benefits from a wide catchment area including the extent of the high density Embakasi estate, Mombasa Road from the Nairobi CBD and the traffic from Jomo Kenyatta International Airport and beyond. In response to the location of the site in Nairobi city, it was necessary to provide a potential usage both in terms of urban entity and returns. The 4-storey shopping mall is designed to react and satisfy a demand for high quality retail spaces in this area. The entire complex is defined by an integration of various retail spaces, restaurants, banks, daycare centers and conference facilities. The third floor exclusively hosts a 30,000 sqft conferencing and exhibition space which will cater for various functions for the neighboring residential 28

and industrial Embakasi area. The shopping mall is located on a 3 acre parcel of land which is deep in nature with its shorter side facing the highway. It comprises of an overall built up area of 360,000 sqft and a lettable area of 165,000 sqft and 400 car parks distributed on the basement, ground and second floor. The multi-functional building comprises of a basement floor which houses 280 car parks, back of house services and lettable storage areas for shops above. This will be one of the first malls to incorporate storage spaces for individual shops in the basement. The basement has a central oval water feature which opens to all the retail floors above and forms the base of the atrium which gets natural light from the central atrium glass roof located on the second floor. The

water feature also acts as a launch pad for a travellator which connects the shoppers from the basement floor to the ground floor at an angle over the water feature. In addition to the travellator the basement also has the main lift lobby and public staircase which connects all the way to the 3rd floor. The ground floor consists of a retail space located around the circular atrium space with natural light beaming in from the glass skylight above. The main entrance to the ground floor is from a drop off facing the main highway. The main entrance comprises of a double height lobby space with the seating area for the coffee shop on the ground floor and the other two eateries overlooking into the same at the first floor. The entrance celebrates an elevated volume enhancing optimum light into the retail spaces. The central atrium is crowned with a glass roof articulating light to various levels and to the water feature at the basement. The shape of the building and the materiality of their facades are juxtaposed to the surrounding low rise buildings to form an anchored and vibrant environment. In essence the key concept behind the design is to achieve and develop the most potential and viable use of the proposed development and at the same time standout from its neighborhood. Unique Design Aspects The entire design compromises of a minimalistic language so as to give prominence to the shops and their respective displays while at the same time ensuring sufficient aesthetic rhythm in the overall public movement areas. The shop fronts have been uniquely designed to form art frameworks for the shop displays. The central atrium is ovular in shape with the basement, ground and first floor facing into a vast water feature with the travelator and escalators crossing on top of it. The four main eateries have been carefully located to face the main double height entrance December 2016 - January 2017


while at the same time having the view of the landing airplanes at the airport located nearby. Finally, Southfield Mall offers a wide range of shop sizes ranging from 200 sqft to 6000 sqft to provide sufficient options in terms of size and usage. Green Considerations Due to the nature of the plot, the shorter front side faces the east which brings in the morning/early afternoon sunshine into the building. This particular facade has the main shops/food outlets set inside with an open space covered with a roof on the double height with seating area in this space. This buffers the existing shop fronts from the sun. The second long facade which is exposed to the sun most times of the day has mainly blank walls which have double thickness in order to reduce heat gain. Service corridors have also been set on this long faรงade to further buffer the shop areas from the afternoon sun. There are large numbers of shaded openings and terraces which allow a natural flow of light and cross ventilation through the mall with a big water feature at the center of the atrium which provides cooling effects to the entire common

movement area. Finally the entire mall has LED light fittings so as to reduce the overall energy bills. Facilities The mall has 2 number 18 passenger lifts, a set of travelators to and from the basement to the ground floor, a set of escalators to and from the ground to the first floor for the customers. There is also a provision for a common goods hoist for all the shops. The anchor tenant shall also have an internal travelator and goods hoist. The complex has a provision of three generators giving a total back up of 1200 kVA to the entire mall. The building also has a 1600 kVA AVR system in order to correct power fluctuations at the point of entry. There is also a UPS back up for important facilities like lighting, CCTV and parking ticketing system. The entire building is controlled by a building management system which shall assist in monitoring any breakdowns, shutdowns or a disaster. Finally the entire mall has a backbone of mechanical ventilation which brings in natural ventilation to individual shops. Location and access to the development The site approximately measures 3 acres in size with a frontage of 75m. The main building is setback by approximately 20m from the plot boundary. This gives a buffer from the noisy highway and at the same time providing a drop off area and front car

parks for the visitors. The location and surroundings of the proposed site have played a big role in deciding the land use of this particular project. The proposed site is strategically located on the busy North Airport Road which connects the Mombasa road from either side to the new eastern by pass and the rest of the busy Embakasi estate. TIMELINES The Ksh 1.4b project commenced in August 2015 and is expected to be ready in March 2017 in time for Easter.

ith years of industry experience in property development, Sterling project Management has established an impressive portfolio of completed residential and commercial projects throughout the country with risk management at the core of its business. Operating in a niche where nothing short of perfection is required, consultancy firm Sterling project management continues to cement its position as one of the leading consultancy and construction firms in the country. Since its foundation in 2009, the firm has grown from strength to strength offering top notch services not only

to residential but also to commercial projects. This has resulted in years of experience being gained in overcoming the most complex and demanding challenges as the firm’s director Andrew Mwaura explains: “We work with seasoned architects and other project consultants in all our projects. Our technical expertise in project management has been of great importance when it comes to project delivery.� Working closely with some of the leading architects and designers, the company has proven its ability to deliver everything from classical opulence to the very latest in contemporary and innovative December 2016 - January 2017


design. Mwaura who had a short stint working in the Middle East construction sector says in all their projects the client comes first. “We are considered to be the foremost project manager of choice for major residential and commercial buildings in Kenya,” says Mwaura. “Our strength lies on our enviable reputation for delivering projects requiring the combined expertise of both complex feasibility studies, together with top technical skills,” he explains. For Sterling Project Management, it is not a about a project, but what a project aims to achieve. In all their projects thorough feasibility studies are done to ascertain the viability of a project. “We are very good at dealing with complexity across any of the disciplines be it residential or commercial projects. This is because we approach our projects from a problem solving perspective. We are very strict on quality as a result we have built much of our success through referral work.” With feasibility studies, the firm is able to advice a client on what type of a project to put in a particular area to avoid a situation where a developer erects a building that is not viable business wise. And this is how Sterling and Project management helps developers to mitigate risks before they occur. With the evolution of the construction industry the firm continues to innovate to match emerging challenges. Sterling and Project management understands very well that delays or stalling of projects is an expensive affair for developers and they endevour to ensure that projects are completed on time. “Most projects are funded by banks and we know the problem that a developer is likely

Mr. Andrew Mwaura

to face incase a project is not completed on time. We tackle this issue by having a clear picture of a project from start to completion,” shares Mwaura. He says that the company maintains good relations with financial institutions in the country allowing them to offer varied and customized consultancy services to their clients. The firm has been involved in bespoke residential apartments such as Kahawa Downs a project comprising of 220 units built at the outskirts of Nairobi. The apartments belong to Housing Finance Corporation of Kenya. Construction began in 2014 and completed at a cost of Ksh730m (US$7.3m. Others include Ridgepark Villas Project in Kisumu and Oak Ridge Apartments in Nairobi. Diversification is key to any business and Mwaura understands it better. Sterling Project management is setting its sight on infrastructure and in this regard they are involved in the proposed Mandera airport in Kenya offering consultancy services with regards to the design, the viability, cost, capacity and usage of the airport. “We take design stage very important in our work because we have the ability to control cost at this level as opposed to trying to manage cost when construction is in

progress,” offers Mwaura. And this is what he wants emphasized even in mega projects in the country. He says one of the reasons why projects stall is the inability of project managers to foresee potential pitfalls and try to evade them before they occur. But a recent boom in the construction industry after a long slowdown has resulted in a major evolution in the kind of projects being done that the available skills have not been able to match. There was a sudden boom in the real estate and infrastructure projects in mid 2000 which required advanced knowledge in project management that was not readily available in the country which is the area that we need to concentrate on advises Mwaura. Looking into the future Mwaura says Sterling and Project management will continue to offer superb services to clients and expand across the East African region as part of their growth strategy. “We are very clear on what we want to achieve. We understand that we are the leaders as far as risk management is concerned and we are determined to maintain and guard that position. We will continue to do our usual projects in real estate sector. However in the future we will be involved more in infrastructure in the country,” he says. To this end, the firm seeks to partner with software developers to ensure that they get real-time information when it comes to mega infrastructure projects where several activities happen at a go. “We are talking to Oracle for partnerships. We know that technology will play a major role in our future projects. All this are geared towards giving our clients the best service,” ends Mwaura.

South Africa’s iconic Moses Mabhida Stadium, which was constructed for the 2010 Soccer World Cup ushered Africa’s construction sector into using engineered tensile membrane structures architecture. Definitely, there is a compelling case why other countries should adopt this approach.

A

s African countries seek cost effective, convenient and energy efficient building methods to address the backlog of infrastructure to meet various development objectives; certainly, one area that they can consider is the use of engineered tensile membrane structures as a permanent building method. Globally, the niche for engineered tensile membrane structures architecture is steadily expanding. In other countries, it has become a standard, especially in the construction of sporting facilities, covered playgrounds

and multipurpose sports halls. Remarkably, engineered tensile membrane structures were used in the construction of the stadiums for the 2014 London Olympics. In Africa, they were used in the construction of Moses Mabhida Stadium for the 2010 Soccer World Cup which South Africa hosted. Product categories To serve a wide array of applications, engineered tensile membrane structures are manufactured in three categories: Tension and Suspension membrane structures, Frame

In such incidences of what is termed as dumping, countries have often adopted a protectionist attitude to the problem of cheap imports. Determined to protect the local industry, South Africa has done just that and has imposed between 14-77 per cent anti-dumping duties on Portland cement originating from Pakistan. Cement makers in East Africa however are disadvantaged in this front after the East African Council of Ministers’ decided to lower the duty on cement imports from non-East African Community countries from 35% to 25%. In the short term, players in the cement industry in East Africa are likely to benefit from the current demand. However it remains to be seen whether this will be sustainable given stiff competition from foreign players coupled with high electricity costs which make up about 40% of the total cost in cement production. In addition plants with more aging equipment are at a distinct disadvantage over the newer players with new plants due to their lower efficiencies. At the end of the day the benefits will be to the customer as producers lower prices to retain market share.

Apex Steel Remains Ahead Through Innovation Always striving to be ahead in ‘cutting edge technology’, Apex Steel has raised the bar a few notches in pioneering the introduction of Couplers in East and Central Africa. Couplers are used to replace the ‘overlap’ in joining of steel rods. Depending on the sizes used, it ensures a savings potential in the overall consumption of the steel. Besides, it is a more efficient process and offers several benefits to ensure a stronger structure. These are Bartec Couplers designed for the connection of concrete reinforcing bars. As a solution provider, Apex Steel has provided value added technology through the introduction of ‘cut and bend’. The ‘cut and bend’ technology helps to raise productivity standards in construction since the Rebars are made to exact specifications. This ensures precision and consistency, lesser labour on site, reduction in material wastage and

WATER TREATMENT

Water Treatment

By Lubwa Leonard ater in Africa is a scarce resource and clean drinking water even more so. According to the World Health Organization fact sheet, contaminated water causes over half a million deaths from diarrhea every year and 38% of health facilities in low and middle-income countries lack any water source. Africa bears the biggest burden as far as accessing clean water is concerned. Although access to clean water and

sanitation in Sub-Saharan Africa has steadily improved over the past two decades, the region measures far below other developing regions. However, as Leon du Casse, Managing Director at Bio Sewage Systems in South Africa says, many authorities are not supportive of the smaller waste water treatment plants and regard them as taking away revenue from there councils, rather than seeing them as an asset in conserving water. Bio Sewage Systems (pty) Ltd manufactures waste water treatment plants with the ability to treat all domestic water. Plants come in either modular or containerized plants. Although to a big percentage access to piped water in Africa is a preserve of the few, Leon says many people are becoming more aware about the value of using clean water. This is according to a poll carried out by this publication. Out of over 700 readers polled, a third felt that water is the most essential ingredient for Africa’s development; a figure matched only by the need for energy. Water treatment entails making water more acceptable for a specific end-use. The end-use may be drinking, irrigation, water recreation, river flow maintenance as well as being safely returned to the environment. The process

removes contaminants or reduces their concentration so that the water is made fit for the desired end-use. In Africa December 2016 - January 2017


the need for water treatment is necessary just as in any developed country and there are several methods of going about this. In Africa, two main methods are used in water treatment. Demineralizing Reverse osmosis involves demineralizing or deionizing water by subjecting it to pressure through a semi-permeable Reverse Osmosis Membrane. The process uses a high pressure pump to increase the pressure on the salt side of the Reverse Osmosis and force water through the semi-permeable Reverse Osmosis. As the water pass through the Reverse Osmosis membrane under pressure, the water molecules pass through the semi-permeable membrane while the salts and other contaminants are held back and discharged via the reject stream, which is then led to a drain or can be fed back into the feed water supply in some cases to be recycled through the RO system to save water. The water that finally makes it through the Reverse Osmosis membrane is called permeate or product water and usually has around 95% to 99% of the dissolved salts removed from it. This method is mainly used for commercial purposes and owing to the level of technology and financial implication involved, its use in Africa is very limited. Chlorine dioxide Chlorine dioxide is a broad spectrum biocide that is effective against all microorganisms. Chlorine dioxide works by first destroying the cell membrane, then the nucleus of the bacteria by chemical oxidation. Because the organism is completely destroyed no resistant strains can develop which enables chlorine dioxide to be used on a continuous basis without the need for alternating biocides. To achieve the most effective disinfectant or microbiological control program, the concept of effective kill (CV values) can be measured and controlled with our approach, using ORP as the indicator. Chlorine dioxide is one of the most effective oxidizing biocides. Chlorination is common practice in many Sub-Saharan African countries owing to the fact that chlorine dioxide is easy to use, readily and cheaply available. Service and Maintenance Water service and maintenance is a complex, tedious and expensive yet very important process as far as delivering clean and safe water for consumption. As advises Leon don’t overlook crucial details but instead buy from credible suppliers who can hold on their guarantee. He adds that Service and maintenance back up are very important aspects because Sustainability means regular preventative and proactive maintenance. December 2016 - January 2017

ADVERTISER'S MESSAGE

Prepare to Coat There’s much more to optimum corrosion protection than using a high-quality protective coating. Preparation of the substrate is absolutely critical. Graco’s new EcoQuip 2 vapor abrasive blaster ensures excellent surface preparation; its new e-Xtreme electric driven airless sprayers provide an outstanding finish with quiet operation.

V

apor abrasive blasting is similar to dry blasting, except that the blast media is moistened prior to impacting the surface. A key benefit is that it minimizes dust than dry blasting; up to 92% less! Thus less containment is required and media clean-up time is reduced. Since vapor abrasive blasting uses less water than slurry or other water-based technologies, pools of water aren’t left behind, and there is less need to worry about toxic runoff. The end result is a cleaner, better contained process. Vapor blast with EcoQuip EcoQuip is Graco’s vapor abrasive blasting equipment. It’s been proven suitable in different industries for a range of applications such as the removal of paint, rust, corrosion, graffiti, industrial coatings and linings, and roadway markings. It’s ideal for cleaning general metal, stone and woodwork; restoring monuments and artifacts; lead and asbestos abatement; and building and site maintenance. In all these applications, EcoQuip has proved to reduce project costs and increase the speed, efficiency and productivity of blasting. Graco has however, advanced EcoQuip 1 with an aim making it even faster, easier to use and more reliable in the field and the result is EcoQuip 2. What’s new with EcoQuip 2? A new factory-set pot pressure is easy to use, with no in-field adjustments necessary, leading to more consistent blast power. A new ventless pot produces a more consistent blast pattern and 50% more usable pot capacity than EcoQuip 1. Set-up and pot pressurization is fast and hassle-free with no external vent plugging. The pot incorporates a new dual-layer coating for maximum corrosion resistance. A new and improved Abrasive Meter and MediaTrak™ leads to quicker and easier set-up, and enables the consumption of abrasive to be easily and accurately monitored. The unit’s controls are simplified, making EcoQuip 2 even easier and

36

more intuitive to operate than its predecessor. Maximum blast pressure has been increased from 8.3 bar (120 psi) to 10.3 bar (150 psi) to give increased power for maximum production. The blast circuit is engineered for a minimal pressure drop with fast-takedown design, faster removal rates and easier service. The new pinch-style abrasive valve is capable of handling coarse and fine media (12-150 grit), giving increased versatility for more applications. One mobile and two skid units EcoQuip 2 EQm is a fully portable entrylevel unit with a built-in hand truck with over-sized wheels for easy maneuverability around the job site. Its blast pressure ranges

from 1.7-12.1 bar (25-175 psi) and its pot size of 100 liters holds approximately eight 25 kg bags of media. Graco EcoQuip 2 skid units are available in two versions. The standard model – EcoQuip 2 EQs – incorporates a coated carbon steel crash frame with basic features. EcoQuip 2 EQs Elite has a stainlesssteel frame and enclosure with additional features for easy and fast set-up. Both skid versions have a 185-liter pot holding approximately sixteen 25 kg bags of media. Ready to spray? Having prepared your substrate, you might now want to spray it with a corrosive protective coating. Graco’s new e-Xtreme electric-driven airless sprayers have been specifically designed for protective coatings. e-Xtreme sprayers offer a flexible alternative to conventional air operated sprayers and are

extremely energy efficient, with a low KWh per liter sprayed. Additionally e-Xtreme reduces energy consumption by up to 80%. Powerful enough to spray most common medium to high solid materials, they provide sufficient volume for the most popular tip sizes (80% of all Graco tips are 0.021” or smaller). They work on a standard residential 240 V, 16 A single-phase power supply. Extremely innovative features The unit’s software minimizes pressure drop effects during change-over. This leads to a significantly smoother and more uniform spray pattern. It also reduces the pulsation transmitted to the painter, resulting in reduced operator fatigue. The e-Xtreme runs at 68 dBA and operators can thus stay close to the unit for a longer time, which increases job productivity. The unit’s electronics are protected against extreme temperatures to avoid motor failures. The extended stall time under pressure will move the unit into a standby mode, which is cleared when fluid moves through the gun again. Flexible range Two versions are available: e-Xtreme 35 has a maximum working pressure of 240 bar (3500 psi) and a dynamic spray pressure at the pump of 220 bar (3200 psi). The e-Xtreme 45 extends those values to 310 bar (4500 psi) and 270 bar (4000 psi) respectively. Both pressure versions are available in 12 different configurations: • Cart-mounted package with or without hose/gun and with or without integrated filter, and with suction set for 20-liter pails (4 versions) • Cart-mounted package with or without hose/gun and with or without integrated filter, and with stainless steel hopper kit (4 versions) • Wall-mounted package with or without hose/gun and with or without integrated filter. No suction set is included (4 versions). December 2016 - January 2017
