The importance of concrete waterproofing

Urban Africa is definitely on the rise

Today there is an extremely wide range of available solutions to waterproof a building, from foundation to roof. Many of these products are new, sometimes valid and multi purpose, however, many are badly failing as they are being applied wrongly.

18 Security in Buildings The African market has seen a great shift into the digital age with regards to building security. There seems to be a big demand for access control because if a system has a flaw or loop hole it will be exploited by intruders

The African continent has recorded a gradual increase in economic growth in the new millennium. Urbanization is also an aspect of the economy that has since registered growth in terms of infrastructure development. However, even with all these noteworthy aspects, the continent lacks in high-rise buildings. Case in point the Carlton Centre, at one point the tallest building in the entire Southern Hemisphere at 732ft still retains the title of tallest building in Africa. However, projects of a similar caliber are now taking root all across the continent. One is Hope City; The $10Bn building which is located in Accra Ghana stands as an architecturally stunning high-tech tower cluster. It is also aimed at making Ghana a goto destination for the information and communication technology (ICT) industry. The tallest tower is planned to be 886 ft. In the meantime, the Al Noor Tower in Casablanca is designed to represent the 54 countries of Africa. The tower presently stands at exactly 540 meters (1,800 feet). 2018 is projected as the date of completion. In Addis Ababa, the Commercial Bank of Ethiopia recently launched the construction of its new 198-meter headquarters. South Africa is not far behind in this venture as well. If built, its Centurion Symbio-City will soar to a height more than double that of the Carlton Centre – 447 meters (1467 feet). It will also feature a rooftop garden and be complete with embedded wind turbines. One thing is for sure, Africa will not be kept down. Just like urban areas in other continents it is ready and willing to play its role. Its expectations are definitely high.

Aveng Infraset builds new concrete roof tile factory in KwaZulu-Natal Aveng

Infraset

has

begun

the construction of a multimillion-rand concrete roof tile manufacturing facility on its premises in Effingham, Durban. Bechtel received the construction project of the year award from Platts for the massive scale of engineering and construction work in the Curtis Island LNG programme.

Bechtel selected to build first high-speed expressway in Kenya Bechtel, has been selected by the Kenyan National Highways Authority to build the first high-speed expressway in the country. The new 294-mile (473-kilometer) route will greatly improve the connectivity, efficiency and safety of road transport between Nairobi and the country’s main sea port, Mombasa, and will reduce the journey time from over 10 hours to under four hours. The expressway will serve as a central part of Kenya’s national transport system, helping to promote trade and development in Kenya and further into landlocked Uganda, Rwanda and Burundi. “This contract shows continued international investor confidence in the Kenyan economy,” said Amjad Bangash, general manager for infrastructure – Europe, Africa and the Middle East, Bechtel. “Bechtel has more than 70 years’ experience building and project managing infrastructure projects in Africa and we are delighted to be working with the Government of Kenya to deliver this important expressway,” he added.

The new roof tile factory will provide the KwaZulu-Natal roof tile market with high quality, affordable roof tiles. Moreover, this will address housing and building needs in the region. It will also deploy the latest roof tile manufacturing and packaging technology. “The decision to establish the roof tile factory using Aveng Infraset’s existing infrastructure

and

resources

makes good business sense. We will be able to increase revenue and improve profitability for the business unit through the dilution of overheads,” says Stephan van Niekerk, General Manager at Aveng Infraset.

Aurecon launches new plans for engineering in Africa Aurecon, a global engineering and infrastructure advisory firm has launched a pioneering approach to engineering in Africa.

ACMK says Construction Project Managers & Construction Managers Bill 2017 will deal with malpractices that have characterized the Kenyan real estate industry leading to collapse of buildings. The Bill comes against the backdrop of incidents of collapsed buildings that have killed many Kenyans in various parts of the country, especially in Nairobi. “This sector has been a field for all and has been dominated by quacks and cartels who are out to make quick money at the expense of safety of Kenyans. There has never been any legal framework to guide construction and project managers,” the association’s chairman Nashon Okowa said.

MANAGEMENT TIPS

5 things your architect will not tell you a template contract that many architects use, and it covers the size, or “scope,” of the project; the homeowner’s budget; a time frame for the project; and a payment schedule. My drawings are not really builder-ready Before you can start shopping for a contractor, you will need your architect’s finished drawings so contractors can bid on them. The problem comes in an architect’s lack of construction expertise, but it can also be the result of the homeowner’s not knowing what kinds of drawings to ask for. Unless you’re doing a very small project, be sure to ask for

B

“construction-level” or “builder”

ringing in the right architect can mean the difference between dream home and disaster area; especially when one puts into consideration the things your architect will not tell you. To ensure the former, first make sure your architect is licensedand not just someone with an education or background in architecture. Once the blueprint’s done, I’m outta here The design phase of a home takes an average of about a month, depending on how often the architect and clients can meet to discuss plans. Once construction begins, a good architect should visit periodically to make sure

" 10

that the building is adhering to the design and to make sure no corners are being cut. Make certain that your contract spells out how often your architect will reappear once construction begins. Another way to keep the architect coming back is to structure the payment plan using time as an incentive: Pay a third of the fee up front, another third when most of the documents are done and the last third when construction is at least substantially complete. If I cannot read your mind, I will just design things my way While you can get a good sense of an architect’s sensibilities

A nother way to keep the architect coming back is to structure the payment plan using time as an incentive.

looking at his past projects, it is up to you to make sure which parts of his style do and do not surface in your home. To help avoid surprises, talk early on and in as much detail as you can about what you visualize.

drawings. These should also include “specifications,” which describe finishes and quality of workmanship. Your contractor and I have communication

I see your budget as an opening bid and my payment plan may take advantage of you Whatever you think your budget is, say it is 10 to 20% lower. Things happen, such as small building glitches, “or you may change your mind” about details or finishes along the way. Such cases often end up with the client having to spend above their budget limit. On the other hand, once you decide that you like an architect’s basic ideas, you should sign a contract to get the terms in writing. Most architectural associations have

issues At the extremes, architects are in this for the aesthetics while contractors and builders are more concerned with logistics, so it is only natural that tension can arise between the two, or even worse, they may just not be interested in dealing with each other. Problems may arise because the contractor could not translate the architect’s plans. To get off to a secure start, try have the architect actually meet (the prospective contractor) before signing on.

OPINION

Africa shows rising interest in green building design

T

he UNEP Sustainable Buildings and Climate Initiative attributed 30% of annual carbon emissions to the global building sector. In response to this and the commitments made by numerous states to reduce their carbon emissions in line with the Paris accord, green building design has become integral in the design and construction of buildings in many parts of the world, as well as in Africa. Over the last six years – in particular – there has been significant uptake of green buildings. In fact, building green or building for sustainability and climate change mitigation is increasingly becoming an industry standard in the South African market – where the industry is doubling every year, and as the Green Building Council of South Africa (GBCSA) introduces more rating tools, the uptake for green buildings will continue to grow exponentially. Added to this, similar market interest in and movement towards green buildings can be seen throughout Africa in the past four years where the GBCSA continues to assist in establishing Green Building Councils north of South Africa’s borders. Through these efforts, to date, GBCs have been established in Namibia, Zambia, Mauritius, Rwanda, Tanzania, Kenya and Ghana. Additionally, six buildings have been accredited under the Green Star ratings credentials, including three in Namibia, one in Rwanda, one in Kenya and one in Ghana.

and water is influencing a mindset change in that savvier consumers are realizing the benefits of being more “green” and, for example, offsetting as much of their energy consumption as possible. Added to this, in the long-term, not only are these green building design adoptions financially beneficial due to reduced energy consumption, but the use of renewable and more sustainable energy resources also has the propensity to reduce the carbon emissions emitted by these buildings and provide increased resilience to Alison Groves, regional director and sustainability consultant, WSP Africa Ms. Groves was honoured with the Established Green Star accolade at the Green Building Convention by the Green Building Council of South Africa (GBCSA) in 2015.

case. The shift is also largely being driven by continuous and growing pressure being placed on the ‘built’ space to address inadequate energy resources, carbon reduction targets and revised building energy efficiency standards. Architects and consulting engineers are therefore constantly coming up with alternative and cost-efficient building designs to offset the impact of the building on its immediate environment. The green design elements may be vast, and vary between buildings, but will most certainly at the very least include things like; the materials used in the building construction, energy efficiency – use of natural light and Proven economic business case floor air flow that might lesson the use of This progressive uptake of green building artificial lighting and air-conditioning, for principles is not surprising as the industry’s instance – as well as water consumption and shift to embrace sustainable practices has a waste to landfill considerations. proven and significant economic business While previously it was thought to be more costly Opportunities to make a difference, fostering to make the upfront capital and supporting a green economy, exist investments to go green, within every project or business initiative. volatility in both the cost and availability of power

uncertain service delivery. Social agenda maturing in Africa In Africa, the social agenda is maturing at a rapid pace and cookie-cutter solutions of the past have now made way for more mature and in-depth engagement. As market awareness grows on building for sustainability, so too does exposure for the skills that exist within the continent that can develop and drive unique or customizable green building design solutions for different markets and climates on the continent. From a sustainability point of view, this is a crucial aspect of every design endeavour – from technology specification to materials selection and labour practices. Opportunities to make a difference, fostering and supporting a green economy, exist within every project or business initiative. As such, it is conceivable that in 10 to 15 years from now, the rest of the world may be looking to Africa for original solutions, experiences and expertise in the careful balancing act of optimizing equally social equity, economic prosperity and environmental stewardship.

Encouraged by the company’s sustained success in producing high quality steel, Apex directors made the decision to acquire Ken Aluminium Products, now known as KAP Plastics, in 2010, effectively becoming a one-stop shop for all construction-related needs in Kenya. Founded in 1978 in Industrial Area, KAP Plastics initially focused on the importation, marketing, and distribution of aluminum products, specialising in injection of moulded plastics and the production of household products such as plastic hangers, jugs, plates, and rubber door stoppers. The company is built on its early success by investing in new machinery and in 2004 KAP Plastics became the first company in Kenya to manufacture Poly Propylene Random (PPR), which were rebranded as “Hydro-flo”, and High Density Polyethylene (HDPE) pipes, radically changing the plumbing industry from galvanized pipes to plastic, saving plumbers substantial time and money. Hydro-flo has been awarded KEBS certification and is the preferred choice for plumbers and contractors looking for quality and durability. It is manufactured from virgin material with no fillers or additives, ensuring sustainability in quality and performance to last over 50 years. Following KAP Plastics’ seamless integration into the Apex Steel family, the company has continued to be at the forefront of plumbing innovations, introducing a series of new plastic and piping solutions to the Kenyan market including round pipes, wall plugs, toilet seat covers, garden hose pipes, ferules and tubings. The group’s unwavering commitment to quality was eventually recognized by the Dutch-based global leader in piping and plumbing solutions, Wavin, leading to a partnership that saw KAP Plastics begin manufacturing PPR, PVC (drainage pipes, electrical conduits, pressure pipes, and rain water down pipes) and HDPE pipes at its state of the art manufacturing facilities in Athi River under stringent quality measures and manufacturing direction from Wavin. The pipes and fitting supplies produced through the Wavin partnership are marketed under the brand name “Apex Water” and include above ground systems, plumbing and heating systems, below ground drainage systems, water management systems, ducting systems and water and gas distribution systems. www.constructionreviewonline.com September 2017 | CR

should be consulted. Additionally, maximum allowable wind speed/gust and derating information is posted conspicuously in the cab or right on the load chart. According to Craig Pieterse of SA Platforms a supplier of AWPs in South Africa, all aerial platforms are designed to withstand a wind speed of 12 meters per second. Obviously some units can handle this with relative ease, while for some units it is about maximum of what they can tolerate. Notably, in the absence of manufacturers’ specific written advice, one should put into consideration postponing the lift should the wind speed/gust between the range of 1520 mph (7-9 m/s). Wind speeds above 20 mph (11 m/s), call for a cancellation of the lift altogether. In such cases loads must be landed and secured, the boom stowed. The following must also be met prior to resuming operations: Elimination of immediate threat should be done to ensure there’s enough time to secure all loads and stow the crane, 30-45 minutes, of wind speeds reaching the 20 mph reading. These wind speeds will be recorded at 30 ft. above open ground or by the 10 meter height of the BNL tower.

Moreover, Mr. Pieterse adds that when purchasing an AWP, it is all about flexibility in the structure of the booms and the overall feeling of strength and comfort. “If a unit feels ‘flimsy’ without evidence of strong winds, chances are that the aerial platform will handle the legal limit with a small margin only. If the unit feels solid when operating under normal conditions it would withstand stronger winds a lot better than a unit that feels flimsy,” he asserts. Mr. Willem Mostert of Crane & Forestry equipment in South Africa further mentions that, the buyer should look for a solid product, a product with years of testing and operation, one that has proven itself. “One of the main factors regarding wind will be to use a unit with as little play possible between the booms and extensions as well as a unit that has sensitive controls. A small and slow movement should result in a smooth and slow movement of the platform; you would like to have as much control as possible. And off course have an accredited installer to install the aerial platform,” he adds. Crane & Forestry equipment does truck mounted platforms that mainly range between insulated and non-insulated platform.

Wind from behind a crane Wind blowing from the rear of the crane increases the radius and decreases the crane capacity, and as a result causes the load to be blown away from the crane. All the same, the buyer should know if he wants to work in- or outdoors with the aerial work platform. Some machines have in- and outdoor approvals, some just indoor approvals. But all the same, the buyer should always consider the permitted wind specifications; this is according to Daniel Yassini of PB Lifttechnik GmbH a manufacturer of AWPs in Germany. Wind from the side of a crane Wind blowing from the side can put a load on the side of the boom and blow the load off vertical; which, in turn, places an additional side load on the boom. According to Daniele Lanzini of Centro Elevatori SRL a supplier of AWPs in Italy, there are no new technologies that have been designed to overcome the impact of wind; however, it is important to pay close attention when using aerial work platforms in case of strong wind. “It is therefore advisable to have a normal basket, it is not recommended

a glass fiber basket or a closed basket because it increases the impact of wind on a larger closed surface,” he says. Furthermore, Mr. Gabrielle Valli of Comet a manufacturer of AWPs in Italy adds that, frankly speaking it is highly recommended not to operate with aerial platforms in case of strong dominant wind. “However, nowadays aerial platforms are very firm and safe and comply with the health and safety regulations imposed by relevant authorities,” he says. Operating a crane between structures The wind tunnel effect, where air

blows around obstructions, can cause local areas of increased velocity that may exceed the safe lifting limit. This is notwithstanding the general wind speed, under which conditions an anemometer should be fixed to the boom point; according to Serena Mingardi of Palazzani a manufacturer of AWPs, in Italy, this will help to measure the exact power of the wind and evaluate if there are good working conditions or not. Furthermore, the anemometer can be installed in the cage and connected it to the platform’s control system so that it can stop all movements of the equipment if it gauges a wind speed more than the safe

A buyer should verify the features of the aerial platforms on the user manual, to know the special recommendations concerning the maximum permissible wind speed.

limits; this is according to Anton Du Plessis the Regional Sales Manager at Palfinger Southern Africa a producer of truckmounted knuckle boom cranes. “All machine operators should however follow the basic practice of not creating a sail effect on or with the machines, this means, no banners or signage should be hung from the machines. A further technique that can be used is to always try and point either the nose or the tail of the machine into the wind. This is part of the guidance to increase safety and all standard work-at-height safety rules and regulations should be adhered to,” says Mr. Chad Pope the Business Development Director at EAZI Africa’s market leader in the rental, sales, servicing and training of work-at-height and material handling solutions. Cold Weather Cold weather can have a negative impact on cranes and aerial work platform operations. Along with making the operator extremely uncomfortable, cold weather can affect many systems in an aerial work platform. Ms. Richelle Fichter of Ahern Companies a dealer in high reach equipment, which permits the safe lifting of people or materials to work at height in the UK, mentions that, cold temperatures cause the thickness of hydraulic fluids to rise significantly, potentially resulting in cavitation in pumps, slow operating speeds, response issues, and poor lubrication for many components. Some of the widely-known problems include freezing of the block and cooling systems, hard starting, dead batteries, and diesel fuel gelling. “Certain steel components cannot withstand extreme cold, which may result in warping

of the machinery. In these conditions, impact loads can cause steels to act more as a brittle material instead of the normal ductility that is expected with a steel product in warmer temperatures,” he adds. When temperatures drop below 10F, consultation with the Plant Engineering Division’s Crane/Hoisting and Rigging Inspector and/or Plant Engineering Division’s Rigging Supervisors is highly recommended. Cold weather lifting restrictions start from below -15oC to -30oC, where all operations involving hydraulic cranes are to be conducted with regard to potential failure of hydraulic components. For critical lifts, cranes should be powered down by at least 25%. For temperatures below30oC to -40oC cranes should be powered down by 40% for all lifts, and halting of all lifting activities should be considered. Lastly, for temperatures below40oC all lifting is prohibited except for extreme emergencies. According to Giuseppe Tesei of Cela srl a designer and manufacturer of Truck mounted aerial platforms in Italy, it is important to purchase units that are tested and certified to a particular temperature. “Our standard units are tested and certified for -25°C of temperature, we also make some special units tested and certified for -40°C” he says. “The growth of the aerial platform (MEWP) market into Africa has been steady due to the efficiency gains that users experience through access equipment, however the current macro-economic market does have its elements of concern, especially for capital intensive industries such as our own,” says Mr. Pope of EAZI.

It is very important during construction to ensure the good quality of concrete and to waterproof the same if exposed to oxidation agents to avoid the deterioration caused by the humidity along in the years (rain, condensation, infiltrations, and so on). In effect, the key of this quality starts in the mix of cement, sand, ballast and water in right proportions, possibly including some additives like fluidifying agents which help the workability of the concrete during the preparation using less water. As a result of this, you have a more compacted and harder concrete which already has some waterproofing characteristics. Challenges in the Kenyan Market In Kenya, waterproofing is often a challenge as in most cases it is not adequately considered at design level; in most cases buildings are being erected and the waterproofing specialists are not consulted on time.

sometimes valid and multi-purpose, they can be used for roofs, foundations, for wet areas and pools as well; however, many are badly failing as they are being used for the wrong purpose, or wrongly applied by incompetent staff. In a traditional market like Kenya, it is always advisable to stick to traditional solutions until the new ones are tested and proved effective; the technical gap between Europe/US and the African continent is getting smaller by the day due to Internet and the specifications issued by foreign professionals for Kenyan projects. So, naturally, the new, performing products that are used abroad will soon naturally enter the market and become popular while the poorly performing ones will not stick around for long. About Scala Scala Enterprises Ltd is under the umbrella of Italbuild Group which was established in Kenya in July 1997 registered and certified as Building Works Contractors-NCA 1, Civil Engineering-Water Works-NCA 2, and Civil Engineering-Road Works-NCA 3. They are renowned Roofing and Waterproofing Specialists with; Polyglass (part of the Mapei Group), TEMA (technologies and Materials), Tegola Canadese Shingles, Mapei, and Index. They provide solutions for foundation slab waterproofing, retaining wall waterproofing and protection before backfill, floor slab humidity and wet areas, façade waterproofing and cladding. Scala is the first company in East Africa to introduce a multi-layer waterproofing solution for the installation of GREEN ROOFING SYSTEMS, which allow flat roofs, balconies and ground floor slabs above basement parking’s to have the possibility of being landscaped and have natural greenery grown. Some completed projects are The Swiss Embassy Annex and The Haveli Towers in Parklands. With TEMA, they also provide land erosion solutions for landscaping around buildings and waterproofing solutions for areas that require drainage in the case the client wishes to install AstroTurf. The high quality standards that Scala applies in the selection of the suppliers of their range of products and the strict co-operation that the company has with them for suggestions, improvement, suitability with the local environment and the peculiarity of any single project is what makes their products unique in the market. They work closely with the suppliers to improve the workmanship standards of their applications. The staff undergo constant training in Europe and their suppliers come to Kenya to familiarize with the Kenyan environment and the differences with Europe. Scala is also a distributor and certified installer of Polyglass from Mapei Group which is the most advanced manufacturer of polymer modified bituminous membranes. The ones they import are tropicalized for best performance. Most of the products Scala sells and applies are adjusted and tested for best performance in tropical climates. 20

COATING APPLICATION

The Basics and Benefits of Airless Spraying Fast and cost-effective way to apply high-quality coatings the tip is less than the maximum flow rate of your sprayer. For example, a 15 thousandths tip (.015) has a rating of 0.91. Hence, the sprayer must be capable of pumping at least 0.91 lpm. Why use a tip with a lower flow rate? When the tip wears, the orifice becomes larger, and the flow rate increases.

What is airless? In airless spray, the fast moving, highpressure liquid stream provides the energy necessary to overcome the fluid’s viscosity and surface tension to form a fine spray. A simple, everyday example of an airless spray system is a bathroom shower. In an airless system, fluid is pumped under high pressure through a spray tip; the tip size and pressure determine the material flow rate. The tip also creates the fan pattern. Airless is in contrast to air spray systems, which inject compressed air into the fluid stream of a fluid such as paint to achieve atomization.

The thickness of the material It’s easy to determine which tip size to use when you know the type of material you’ll be spraying. Lower viscosity (thinner) materials, such as stain or lacquer, require a spray tip with a smaller orifice or hole size. Heavier materials, like latex, require a tip with a larger orifice. Extremely heavy materials like elastomerics and blockfiller might require spray tips larger than .035.

Advantages of airless sprayers Airless sprayers provide an easy and economical way to apply coatings no matter the amount of solids present. Indeed, professional painting contractors prefer to use airless sprayers for three key reasons: Speed: Airless spraying is up to four times faster than brushing or rolling, enabling more jobs to be completed in less time, and reducing labor costs. Quality: Airless sprayers produce an even coat of paint on all types of surfaces, leaving a high quality finish. Versatility: Airless sprayers can be used for a wide range of coating materials, including interior and exterior jobs, and can easily be transported from job site to job site. Airless sprayer tips While the fluid section, pressure controls, and power sources are important components of airless sprayers, if one refers to the pressure controls as the “brains” of the system, then the airless spray tip is definitely the heart of the system. An airless spray tip helps determine the fluid flow or the amount of coating applied, and determines the spray pattern (i.e. fan width). All Graco airless sprayer tips are made out of the highest grade of tungsten carbide, the most abrasive-resistant material used for airless spray tips. 22

Choosing the right tip Selection of the correct tip is essential to maximize productivity, as the tip determines the fluid flow and the size of the spray pattern – the fan size. Using the right tip results in maximum control and minimum overspray, which means faster work and less paint usage, which ultimately means finishing the job quickly without wasting paint. To choose the right spray tip, several factors need to be considered, such as the material thickness, the sprayer’s maximum flow rate and the best fan size for the job. Knowing when a tip is worn and why to replace it are also important. Spray tips are rated in terms of liters per minute (lpm). Before determining which tip to use, the following factors should be considered: The sprayer’s maximum flow rate For optimum performance, the sprayer must have a maximum flow rate higher than the flow rate of the tip, so be sure the flow rate of

The best fan size for the job Fan size – the width of the spray pattern – determines the area covered with each pass. For a given tip orifice, a wider fan delivers a thinner coat, less defined spray pattern, more overspray, and faster coverage on broad, open surfaces. A narrower fan delivers a thicker coat, more defined spray pattern, less overspray, and better control when spraying small or confined surfaces. To maximize productivity and reduce labor costs, choose a tip with the right fan size. In general, a larger fan size increases production with less control, and a smaller fan size decreases production with more control. Tips for extending the life of spray tips include: • Spray at the least amount of pressure necessary to atomize material. • Strain the coating material prior to spraying, using a nylon strainer bag. • Use correct size filters. • Clean filters after each use. • Use a soft bristle brush to clean tips.

SECURITY

Security in Buildings

T

he African market has experienced major changes in building security over the years. According to Mr. Muhammed of Crown Hyper a world renowned

company, that provides premium brand products in the field of Electronics and IT in South Africa, the market is now open to innovation and it is a place that closely follows technology; therefore projects are taking place based on standards preferred by investors. The best products produced in countries like Turkey and France, are brought to Africa where the projects are. As a matter of fact, many international companies carry out production and testing in Africa. Therefore, many technological developments are spreading from Africa to the rest of the world.

most companies are doing a shift to cloud computing where the data is not stored locally on a hard drive but in secure servers all over the world.

Building Monitoring The way to achieve efficient monitoring is by installing an integrated system, this is according to Mr. Cem Atam of Kekova a security consulting firm in Turkey. It is possible to control the system with a single center (more than one spare structure according to need) and less hardware. This will reduce both operational and maintenance costs, increasing your business strength, enabling you to increase profitability in your business and have a long-lived facility. “The Turks have a proverb; “from being one, strength is born.” In other words, we should think of our facilities as a living organism; we have to follow every functioning or stationary point and watch the changes. This plays an important role both in terms of security vulnerabilities and control of the system’s good operability,” he says. Documentation of security matters Every client has unique documentation requirements for their project. Depending on the type of facility and the regulations, codes, construction and service technical information

CR | September 2017 www.constructionreviewonline.com


required, the extent of required or requested documentation can vary radically. In the design and engineering stage, this may mean submittals to authorities, architects, owners or other stakeholders. Proper process and form for this type of documentation matters. The security designers should possess the ability to create specialized output of documentation. This include electronic forms such as AutoCad, Building Information Management (BIM) or other systems. The consultant should work with you to design the documentation package that you require, from design, to construction and to post-delivery support. According to Sibusiso Dhlamini the Sales and Marketing Executive at Tagtron Solutions a specialist in EAS and RFID solutions offering a range of hardware security equipment in Sub Saharan Africa the best way to document data is to have it done automatically using software. If you are using RFID, simply saving the RFIDs ID number with a timestamp in a database saved to the cloud is all you need. Then you can analyze the data at a later stage. As long as you have the data you can always compile new reports from it. “We find that most companies are doing a shift to cloud computing where the data is not stored locally on a hard drive but in secure servers all over the world. This means if your company burns down or a virus deletes everything your data is still secure. Most cloud servers can even back track stored data for a few months meaning that even if someone deleted all your data on the cloud you could still recover everything,” he adds.

emissions, etc. Some of these certifications can be taken during

Government policies Governments in most manufacturing countries have formed commissions to provide regulations and standards in the market. Manufacturers develop products that meet these standards to ensure quality and good service. These commissions include: the European standards committee (CEN), British Standards Institution (Bsi) and Turkish Standards Institution (TSE), National Institute of Standards and Technology (NIST) etc. These commissions document matters with regards to: information security, durability, energy consumption, carbon

consumers of security services are not only becoming savvier to

the production phase and during the usage phase. For example, like a LEED certificate. Considering the importance of these commissions, Mr. Atam advises that, it is paramount to develop policies that follow technological developments, overlap with life and regional conditions, and have vision. Choosing the right security system Generally, most countries have institutions that formulate certain standards by which the products in the market are usually shaped within. These standards are generally based on regulations or standards of neighboring countries and producing countries. When it comes to choosing the right product, it is very important to talk to experts in the field. “It is highly advisable to meet with a few consulting firms and present your ideas or vision, then go for the best system. The choice that you make should be guided by your expectations for tomorrow, not today. This means that the products should have a low failure rate, a large service network and low operational and maintenance costs. Moreover, the consumer should ensure that the product is certified regardless of the price; a certified system has passed many tests and has a good design,” asserts Mr. Atam. Nevertheless, Mr. Albert Abincha, a Business Executive at Cathexis Technologies a leading IP Video Management Software Developer, specializing in Surveillance Solutions for the international market in South Africa mentions that, the technological changes but are also seeing the value in consulting with skilled installers and integrators who can provide them with the best consultation on the right type of system for their operations. According to George Mutai a Sales Engineer of South Africa’s Axis Communications, a leader in network video; by coming up with a needs analysis, finding the right partners and following best-practice. The selected solution should be able to address the needs that the client wants addressed.

An owner of premises, Architect and an Engineer engaged in the design, construction, extension or alteration of premises shall incorporate solar water heating systems in all new premises designs and extensions or alterations to existing premises. • An electric power distributor or supplier shall not provide electricity supply to premises where a solar water heating system has not been installed in accordance with the Regulations. The affected premises effectively includes all domestic dwellings or residential houses, commercial buildings (including hotels, lodges, clubs, restaurants, cafeterias, laundries, eating places and similar premises), health institutions (including hospitals, health centres, clinics and similar medical facilities), educational institutions (including universities, colleges, boarding schools and similar institutions). While owners of pre-existing affected buildings still have a two-year window to install solar water heaters in their premises, developers, owners, architects and engineers engaged in the design and construction of new buildings and extensions or alterations of pre-existing affected buildings have to comply immediately. For new or upcoming buildings, the regulations are likely to have far reaching effects because they impose an obligation on any electric power distributor or supplier (including the Kenya Power) to refrain from providing electricity to any affected buildings if solar water heaters have not been installed in accordance with the regulations. Although the rules came into force in May this year, the ERC granted a further extension of six months to enable property owners to arrange for financing and installation of hot water systems in their premises. Upon the expiry of this extension, the organization is empowered by law to carry out inspections for purposes of enforcement and has already indicated its readiness to do so. The ERC’s preliminary audits show that 150,000 of three million buildings (both new and old) have installed hot water systems – leaving thousands in the regulator’s crosshairs.

of buildings. Boarding learning institutions are among those that have shown poor compliance. The solar kits are expected to help conserve energy and lower demand for electricity as increased economic activity and connection of more homes to the grid put pressure on existing power generation plants. Besides, installing solar panels could help homes slash electricity bills by up to 20 per cent and water heating costs by up to 60%. But property developers have cited prohibitive costs of solar heaters as a deterrent to increased uptake. The cost of a complete solar water heater system for domestic use ranges between KSh125,000 and KSh150,000 (approximately US$1,200 and US$1,400) per unit and between Sh600,000 and Sh2 million (US$ 5,700 and US$19,000) for commercial buildings. While the new rules have been received by the affected parties with some dismay due to cost implications, they are a boon to suppliers of solar water heaters and related services. Already, many of these companies are reporting a surge in enquiries and sales of solar water heaters unlike in the past where they relied on salespeople to push their products in the market. The number of new entrants in the sector is also rising with many companies rushing to supply the soon-to-be lucrative market.

For water heating, they offer both split/ centralized solutions and thermosiphon systems from a low capacity of 100 liters to as much as space can allow. According to David Maranga who is a Product Manager with the company, adoption of solar energy systems is a prudent decision owing to the rising cost of living and doing business. “Many people have started to appreciate that solar is a worthy investment with a very short payback period and long-term benefit,” he says, adding that technology has changed over the last few years making it more affordable and efficient. He however cautions that in a market filled with cheap solutions, due diligence is important.

as ability of suppliers to provide reliable after-sales service will play a huge role in determining a customer’s decision to select a particular supplier. Being a fairly huge investment, few buyers are willing to stake their money in a product that is unlikely to serve them efficiently for a reasonable period. Customers, especially individual home owners and institutions, would also be looking for a return on investment through significant reductions in energy costs within the first three or four years after installation. There are a number of reliable companies that supply quality solar water heaters among a myriad other energy-related products. Some of these are fairly new in the business while others are established organizations that have amassed substantial expertise in these products. Most of the solar products are sourced from Europe and Asia (mostly China). Hotpoint Appliances Limited Hotpoint Appliances Ltd has been in the East African market for the last over 30 years and has become a household name trusted by the market. In the last eight years, the company has diversified into engineering and five years ago started offering renewable energy solutions. Hotpoint Appliances offer complete solutions i.e. design, supply,

Chloride Exide Chloride Exide is another well known name in the solar energy sector. Established more than 50 years ago, the company has been at the forefront of renewable energy solutions including solar and wind power harnessing. Their solar water heating systems are long lasting, efficient, user-friendly and low maintenance. Negawatt Limited Negawatt is a relatively new entrant on the solar energy solutions market though the people behind the company have extensive experience in the field. The company supplies and installs Led Lights, Solar PV, Solar Water Heating, Solar Street Lights, Solar Consulting and Feasibility studies. Their products are sourced from Germany, UK, France, Australia, India and China. Operations Manager Isaac Kiunga says Negawatt distinguishes itself from the competition by offering affordable Tier 1 products with robust design. The fact that they systems are turnkey and financing arrangements can be made for the customers are other attributes that attract customers to the company. According to Mr. Kiunga, there has been “a tremendous uptake” of solar products in the last few years. He advises prospective customers to go with experienced suppliers who can guarantee quality.

For solar water heating, the company offers its Sunstream Solar Water Heating System which is available in 150, 200 and 300 litres. When it comes to choosing a supplier especially for projects, Mr. Otieno advises: “Your solutions partner should have diverse experience in systems integration and commercial project management, with a demonstrated track record of delivering projects on budget and on time. The company should be well-versed in local and national building codes as well as detailed reporting and organization.” He also cautions against dealing with inexperienced suppliers with questionable products and no after-sales service. “With the infiltration of many subpar systems into the market, it is best to be sure of the quality of systems being purchased,” he says; adding that, as with everything else, in solar energy products, cheap is expensive.

most companies are doing a shift to cloud computing where the data is not stored locally on a hard drive but in secure servers all over the world.

Go Solar Systems Limited Go Solar Systems Limited has been supplying solar products and services for more than 10 years. Based in Nairobi, the company sources its products from Germany, Turkey, United States of America and China.

He advises prospective clients to choose their solar solutions wisely and not compromise on quality. “Solar is a long term investment and the wrong quality will result in a long term regret due to poor and dismal system performance,

not to mention the obvious loss of money involved in the transaction. Cheap is very expensive,” he adds. Helios Agrosol Limited This is a relatively new company on the Kenyan market. Helios Agrosol Limited offers solar water heating solutions from a capacity of 120 litres to 9,000 litres. The company serves homes, hotels and hostels. Its products are imported from Greece.

PROJECT

Xinhua to get new home in Kenya

X

inhua News Agency is the official press agency of the People’s Republic of China. It is the biggest and most influential media organization in the country and operates more than 170 foreign bureaus worldwide. Xinhua has been operating in Kenya for many years. To consolidate its operations, the Agency sought to build a complex that would serve as office space and at the same time offer accommodation and recreational facilities for its employees. And therefore in January this year, a team headed by leading Kenyan architectural studio – Tectura International – embarked on the task of realizing this vision. Once complete in September 2018, the complex, located on George Padmore Road in Nairobi, will have the following facilities: • Dining room with kitchen, outdoor dining area and rooftop restaurant • Roof terrace • Conference/Exhibition room • Executive Lounge • Library • Two open-plan office spaces • 30 offices • 24 studio units • 36 bedroom units. The complex will also have facilities for indoor games as well as a badminton court, swimming pool and gymnasium. A total of 60 parking spaces have been provided, with 53 located in the basement and the rest on the surface. There will be four elevators, a standby generator and a borehole. Design Aspects According to Architect Kihara Mungai of Tectura International, with the end user being a news agency for distributing important news to the Chinese Communist Party and Central Government, the planning concept, character development and form abstraction borrowed from the elementary geometry of wave motion. The architect had to find a perfect balance between “official, homely and recreational” use of the whole development while still maintaining a seamless set-up with inconspicuous interfaces. “At the back of our minds, this being a Chinese government project, it has been very important that design resolutions are reached in conformity with not only local but also Chinese design codes”, says Arch Mungai.

Green Considerations The Xinhua complex will feature grey water recycling, solar reducing plants, rainwater harvesting and LED lighting as part of the architects’ green intervention. There will be natural temperature control with the main spaces facing North-South for maximum light while minimizing latent heat from the sun. All East-West facing facades have sunshades. Ventilation will also be natural. With the wind direction being from West to East, the building will allow wind to pass through it creating an area of low pressure that will aid in natural ventilation of the rooms. Solar water heating is also envisaged in the complex. Client: Xinhua News Agency Architects: Tectura International Ltd.

PROJECT

Fostering social integration through recreation

Once complete towards end of 2017, the Multipurpose Sports Complex, which is under construction, will be a landmark building that will contribute positively to the realm of Klipspruit, Soweto.

L

ocated in Klipspruit, Soweto, the Sports Complex is the fourth phase of the Nancefield Station Precinct project, a multi-phased public environment upgrade. The Nancefield Station Precinct is a City of Johannesburg Transit Oriented Development (TOD) project. Through the Nancefield Station Precinct upgrade, the City of Johannesburg aims to provide "a restructured space economy that gives poor households better access to welllocated accommodation, jobs and markets; optimised land use and energy consumption; and improved living standards and mobility for large numbers of people in well-serviced 42

and managed transit neighbourhoods". The City's vision is to transform the space to include decent housing and social facilities and attract business investment to the area. In a nutshell, the TOD seeks to achieve the following: • Create a visibly improved public environment in the Nancefield Precinct; • Develop a unique identity and showcase the Precinct's potential; and • Support investor and public confidence in the area The Sports Complex’ architectural elements In an interview with the team from IYER Architects, Construction Review grasps

three key elements that have been considered in the Sports Centre’s design, from an urban design and planning perspective. Firstly, the idea was to create a landmark public building that contributes positively to the public realm of Klipspruit. Secondly, the vacant site was used as a pedestrian connection to move across two sides of Klipspruit. Whilst a large portion of the site will be enclosed by fence or building, this connectivity has been retained by creating a landscaped pedestrian link connecting Mofokeng Street to a linear park, which was implemented as part of the broader upgrade.

CR | September 2017 www.constructionreviewonline.com


Thirdly, there is an urban logic to the positioning of the building and external elements in relation to the context. The building is positioned close to the street to create a positive edge and interface. The external landscape elements (courtyard, training courts and splash pad) are located on the park side to act visually and spatially as an extension to this linear public space. Sustainable use of resources Worth underlining is the incorporation of innovations in the design to promote sustainable use of resources, which include: • Heat pump systems • Energy efficient heating, ventilating, and cooling system • Lower volatile organic compound (VOC) Paint and finishing materials • Low water consuming sanitary fittings • Vandal proof sanitary fittings • Intruder-proof glazing • Use of polycarbonate material for second storey wrap-around screen. Brings in light without the cost of full height glazing. • Cladding on walls - no painting required, lower maintenance Quality assurance A number of steps are being followed religiously in the course of construction to ensure that the architectural blueprint is being implemented as planned.

These include: • A Quality Control Plan formulated by the contractor and approved by relevant consultants. The QCP has requirements that should be met by the contractor. • Regular site inspections • Samples approval of all items that are to be installed • Shop drawing process of special items • Mock-up samples of unique items The Iyer team reveals that, as far as possible, the contractors have stuck to the architectural blueprint. The only “minor” change was value engineering the steelwork which

resulted in the use of smaller steel members. If everything goes according to plan, the project is scheduled for completion by December 2017. An intra-disciplinary studio IYER is an intra-disciplinary studio specialising in urban design, planning; architecture and landscape design. These cross disciplines have created a project that is unique, of a high standard, holistic and responds well to its surrounding context. The firm looks forward to involvement in more urban renewal projects in the country.
