Kaytech Reinforces Site of new Mamelodi Mall Kaytech’s quality separation, basal reinforcement and subgrade stabilisation solutions for the new Mamelodi Mall, east of Pretoria, resulted in significant savings for New Africa Development. After inspection, D & G Consulting Engineers encountered extremely weak clay subgrade that could neither support massive stormwater pipes nor future construction of the platforms for the structures. With the only conventional option being an expensive layer of dumprock (over one metre thick) to compensate for the low bearing capacity of the insitu soil, Kaytech was consulted to recommend a favourable solution. It was decided that RockGrid PC 100/100, Kaytech’s composite geotextile, would be installed as a separation and reinforcement layer in the bedding of the stormwater pipes. This solution helped facilitate a reduction in the layer of dumprock required. The PC 100/100 composite geotextile was used as the combination of a nonwoven separation layer in conjunction with high tenacity, biaxially orientated multifilament polyester yarns, giving RockGrid PC its exceptional characteristics; a high tensile modulus providing excellent reinforcement properties and, compared to polyethylene or polypropylene grids or woven fabrics, minimal creep deformation.

ASSOCIATION NEWS
Southern Africa Readymix Association: New dawn
The Southern Africa Readymix Association of Southern Africa (Sarma), has since began a new age. As they continue garnering momentum, the association is also surging forward on a different footing altogether as some of the bigwigs give way to a new crop of leaders to advance the local industry into the global market; Johan van Wyk has thus been appointed as Director of Sarma. Secondly, from a referendum conducted earlier on this year, a proposed initiative was agreed upon with purposes to consolidate all concrete industry bodies. However, the move required a withdrawal from the joint office shared with the Aggregate and Sand Producers Association of Southern Africa (Aspasa). Although the external environment proved to be tough and has since affected the business and market unfavorably, the management committee is fully prepared to tackle any issues that may come up. “We pledge on behalf of the management committee, that we will work tirelessly to realize the objectives of Sarma. However, it requires full support from all readymix suppliers to further improve the image of the readymix industry as well as move the industry to a new position of profitability and sustainability,” promised Avi Bhoora, the new Sarma chairman.

UNRA board calls for more funding for road projects in Uganda The outgoing Uganda National Roads Authority (UNRA) board chairperson has called for continued financial support for the government-funded roads to facilitate timely completion and guarantee quality. Angela Kiryabwire said the Government should ensure continuity in the funding of road projects in the country to avoid extra expenses that arise from delays. Kiryabwire made the remarks while carrying out an on-the-spot inspection of the 74km Mukono-Katosi-Nyenga road. The road is among projects fully funded by the government. She further pointed out that although works on the Mukono-Katosi-Nyenga road are behind schedule, the

On the other hand, since the alternative building materials are not always readily available in South Africa, import costs are not pocket-friendly to many.
problem was not caused by the contractor and consulting engineers but the major challenge was due to the limited access to the right of way as a result of unpaid compensation to the land owners. “Timely payment of the road contractors and consulting engineers as well as resolving issues related to people affected by the road project (PAPs) through the existing legal framework is still a problem affecting this road,” Kiryabwire said.

EVENTS NEWS
The Big 5 Construct North Africa
SPACE (Sustainable Properties Africa Conference & Exhibition) The inaugural SPACE event (Sustainable Properties Africa) will be held at the Radisson Blu Hotel, Upper Hill in Nairobi on 13-14 June 2017. SPACE will attract an international audience of decision makers involved in real estate developments across the African continent. Currently, building “sustainably” is considered a costly process and, as a result, developments are bypassing opportunities to reduce operational costs and long-term value of projects. This short term thinking is not only damaging to the environment but will ultimately be damaging to the pocket as regulations are passed to incorporate sustainable building practices and also investors will look to have assets in their portfolio that have longterm value and higher margins.
The Big 5 Construct North Africa will be a global meeting place for all manufacturers and buyers of construction products, industry experts presenting CPD certified educational programmes and more. Organized by dmg events in collaboration with Elan expo, the exhibition will bring together buyers and sellers together to conduct business, forge relationships and exchange knowledge. Scheduled for 25 – 27 April 2017, the event will take place at PARC DES EXPOSITIONS DE L’OFFICE DES CHANGES, CASABLANCA, MOROCCO. The exhibition will cover a wide range of building and design categories from HVAC to Windows and doors, Finishes (Coatings, paintings) to concrete related products. Exhibitors include manufacturers and distributors of international and local construction products showcasing the latest innovations for buyers such as architects, interior designers, procurement managers and engineering professionals attending the event. Unique to the show is the CPD certified, free to attend educational programme, extended to both exhibitors and visitors.

Acotec is made from Leca or concrete, ensuring great resistance against moisture and temperature differences while also dampening sounds from elsewhere in the building. “Acotec can be used
in practically any application anywhere in the world. Thanks to the innovative manufacturing method, the length and thickness of the wall can be adjusted on the production line in accordance with the application and the construction requirements. The thicker the wall is, the better its sound insulation and fire resistance properties. Increase in the thickness can result in up to 120 minutes of fire resistance. This is a vital quality in places such as senior homes and hospitals, where evacuation takes longer,” says Jani Eilola, Product Director at Elematic. A thicker wall also helps dampen sounds from other rooms and apartments. “The less noise you can hear from other apartments, the more comfortable living is. The engineering and utility rooms in hospitals and office buildings are often full of noisy equipment, so the sound insulation of the partition walls has to be good.

OPINION
Why Kenya’s Construction industry is Booming Joyce Mbui is Bowmans Kenya Senior Associate for Banking, Real Estate, Construction and Finance.
Kenya has been the preferred hub for multinationals and other international organizations with operations in East and Central Africa. 8
T
he past decade has seen significant growth in most key sectors of the Kenyan economy, thanks to a vibrant private sector and the everincreasing foreign appetite for investments in Africa. Indeed, Kenya has been the preferred hub for multinationals and other international organizations with operations in East and Central Africa. In response, the Kenyan Government has invested heavily in infrastructure development, while taking steps to improve the legal and regulatory framework in key sectors of the economy. Evidence of investor confidence in the Kenyan real estate and construction market, especially in relation to commercial property, is Old Mutual Property’s recent investment in the Two Rivers Mall. UK-based Old Mutual invested KES 6.4 billion in the holding company of Centum’s Two Rivers Mall, giving it an equivalent 50% stake in the firm. The country has also seen investments from the Delta Africa Property Fund, Retail Africa and Abland – all from South Africa. AVIC International Holding Corporation of China is also expected to invest over US$ 200M in constructing their Africa Headquarters in Nairobi. The multi-user development has been reported to contain the highest office block in East Africa and will undoubtedly reshape Nairobi’s skyline. The spill-over effect of this increased demand for real estate, however, is the high cost of developing new property. The market is facing extreme undersupply especially in housing for the lower segment of the populace; so much so that a tax incentive was recently introduced into law which entitles developers who put up at least 400 low cost residential units to pay a reduced corporation tax rate of 15% (down from 30%). It is against the backdrop
of the enactment of the Capital Markets (Real Estate Investment Trusts) (Collective Investment Schemes) Regulations, 2013, that the Nairobi Securities Exchange became the fourth African bourse to launch the Real Estate Investment Trust (REITs) market in the 2013.REITS are regulated investment vehicles that enable collective investment in real estate. Investors, both retail and corporate, pool their funds under the REIT umbrella to invest in real estate projects. The launch of REITs was meant to further enhance financial inclusion in Kenyan capital markets. REITs would provide average investors belonging to the growing middleincome segment the opportunity to invest in large-scale commercial, residential and industrial properties, without requiring large sums of money. It was hoped that investors would gain from the income and capital appreciation of the portfolio of properties in which a REITs fund was invested and the creation of a liquid market in immovable property. REITs in Kenya are structured as trusts rather than companies. The properties are held in the name of a corporate trustee who is the custodian of the REIT assets but managed by a corporate REIT manager. There are two types of REITs – development and construction REITs and income REITs. Securities in the former can only be offered to professional investors who understand development risks. However, income REITs can be offered to both professional and retail investors. The first income REIT was listed at the Nairobi Securities Exchange late last year by Stanlib, which is controlled by the Liberty Group of South Africa.

site. This is known as ‘charging’ the mixer. When the drum rotates in the other direction, the Archimedes' screw-type arrangement ‘discharges’ the concrete out of the drum. From there it may go onto chutes to guide the viscous concrete directly to the job site. If the truck cannot get close enough to the site to use the chutes, the concrete may be discharged into a concrete pump, connected to a flexible hose, or onto a conveyor belt which can be extended some distance (normally ten or more metres). A pump provides the means to move the material to precise locations, multi-floor buildings, and other distance prohibitive locations. Buckets suspended from cranes are also used to place the concrete. The drum is traditionally made of steel but on some newer trucks as a weight reduction measure, fibreglass has been used. In-transit mixers are made to transport and mix concrete up to the construction site.
How convenient is your concrete mixer?
M
any contractors always find it advantageous to have their own concrete mixer as opposed to depending on outside vendors and if you are a new entrant to the construction industry it is an investment worth making. The right mixer will ensure independence, flexibility in working time and convenience and goes a long way in cutting costs and ensuring a continuous and uninterrupted workflow. While weighing on whether to call on ready-mix concrete delivery or owning your own mixers, many factors should be weighed. These include among others, job scope, the location of the site, size and quality of staff and the time frame attached to the project. For instance, it is counterproductive for a contractor to use a portable concrete mixer when he needs to pour a slab of 50 square metres. He is much better served using ready-mix. Similarly, if a job needs 10
to be completed in an hour so contractors can move on to the next job, ready-mix is a smarter choice. In-transit Mixers In-transit mixers are made to transport and mix concrete up to the construction site. They can be charged with dry materials and water, with the mixing occurring during transport. They can also be loaded from a ‘central mix’ plant, with this process the material has already been mixed prior to loading. The concrete mixing transport truck maintains the material's liquid state through agitation, or turning of the drum, until delivery. The interior of the drum on a concrete mixing truck is fitted with a spiral blade. In one rotational direction, the concrete is pushed deeper into the drum. This is the direction the drum is rotated while the concrete is being transported to the building
Advantages The biggest advantage of transit mixers is that these do not allow segregation of concrete because of continuous rotation. Unloading of concrete batch can be done at will in full or partially. Drum of concrete mixer doesn’t allow any foreign material to enter the concrete load. Concrete can be unloaded to a conveyor belt, a concrete pump or into the chutes. As the capacity of available transit mixers varies from 4 cum to 12 cum, choice is available as per site requirements and concrete production rate. Additionally, more advantages include: vast improvement in the quality and uniformity of concrete and enhanced speed of construction; savings in labour, reduction in wastage, elimination of material procurement requirements and storage hassles; plus the environmental conservation aspect whereby the surroundings of the site remain clean. Portable Mixers The smaller models which are normally available in sizes ranging from 3 to 12 cubic feet; will fit in the trunk of most cars, while the larger capacity units can be towed easily on wheels or hoisted onto a truck for longer distances. With their small size and easy portability they can be used even in remote areas that characterize most African settings. To a budding contractor wishing to establish himself but facing financial constraints, this could be a perfect start up as their costs are quite accommodative April 2017

Advantages The biggest advantage in owning a portable mixer is realized when working on sidewalks, foundations and binding block, and when preparing mortar bases. Many decorative concrete contractors find the portable mixers ideal too. A good example is the monument works industry which mostly has mixers mounted on their own trucks. The same holds true for many landscape and fence builders. One interesting model of portable mixers is the wheelbarrow-style mixer that fits comfortably through a 30-inch-wide opening. This allows the user to mix and pour right where the product is needed. On the other hand contractors working in a back yard or spacerestricted area where accessibility is a problem will find a portable mixer much more effective. Smaller mixers are highly recommended for mixing concrete to anchor fence posts; for patching; for small concrete slabs on grade; and for mixing non-stick grout. For high-production jobs such as concrete slabs, sidewalks and block walls, larger-capacity models are better suited. There are many styles and sizes to choose from, from a 2-cubic-foot pedestal style to a 31⁄2-cubic-foot wheelbarrow style to a 9-cubic-foot towable unit. The utility mixers start at 11⁄2 cubic feet and can be mounted or be made stationary; or an optional low- or high-speed tow kit can be added. The mixers come with either electric- or gasoline-powered sources. Single-phase electric motors are available in the 1⁄2to 11⁄2-horsepower range while gas engines span from 3 to 13 horsepower. Mixers also have speed controls that can be adjusted to fit the requirements of the specific job. According to Pooja Pandya of Engineering Supplies Limited, drum capacity; cycles per hour, mixer build quality, life of the product and availability of sales and service are very important factors to consider when a contractor is looking for a portable concrete mixer. Engineering Supplies offers a wide range of concrete mixers for the East African market. “Our products are quite unique in the market, some of the unique aspects include: the 6 ring segment that makes repairs more cost friendly and ensure a longer life to the mixers and the rental model which is used regularly by rental companies, proving its strength and durability,” she said. “The products are designed in such a way that there is a balance between price and quality,” she April 2017

affirmed. Most manufacturers offer steel and polyethylene drums to fit individual user preferences. Steel drums are more durable, but cleaning can often be tedious and other damage to the drum is a possibility. Poly drums, which resist rust, can be cleaned in minutes by simply tapping with a rubber mallet and they are lighter than their steel counterpart. Choosing you mixer The nature and volume of work is a factor to consider in choosing the right mixer. Big-scale construction projects require bulk concrete mixers which can mix large quantities of concrete both onsite and offsite. For small scale projects, smaller mixers can apply. The size of construction site is a major factor to consider. Remember smaller mixers can fit well in squeezed sites while large open sites can comfortably accommodate the bigger ones. Martina Giustelli of MEV Srl argues that, customers today are aware that a cheap but low quality machine affects the quality of work and reduces profits. “Moreover, a quality product has a longer life, has better performances, gives less maintenance problems and ensures the safety of operators. The initial expense will be repaid by a considerable saving over the years,” she said MEV Srl has decades of experience in manufacturing machinery and equipment for the building sector. “Our range of products includes Self-Loading Concrete Mixer from 1 to 4 m3 output. Africa is one of our main markets and right now we are seeking to 12

recommendations,
contractors should check the oil levels and filters of portable mixers daily. In using the mixer, the mixer V-belt and pulleys should be tight while the necessary parts should be greased frequently. Gears on a concrete mixer, however, should never be greased. Debris, sand, sediment or other material can become trapped in the gears, causing major damage to the unit. Simple cleaning and lubrication will help keep the mixer running trouble-free for years to come. According to Mr. Adalberto Marcello of CIFA customers need to give great attention not only to the machine specifications, but also to the people that are going to service the machines. CIFA is a one-stop-shop company for concrete machinery “We are well known in the industry to provide a first level assistance and service to our customers. Our technicians all over the world are trained in a dedicated facility called CIFA Academy,” said Mr. Adalberto. “Africa is still a small market compared to Europe or ASIA or America, but it has a strong growth and we really want to contribute to the full development of the continent.

CONCRETE
Concrete Surface Treatment
C
oncrete Surface Treatment is a process of successive stages that entails preparation, absorption, painting, application of mass and coating. Such treatment has a positive effect on the floor’s functionality and other similarly important issues. The characteristics of a surface-treated concrete floor are affected by the correct selection of the concrete type, preparation and surface treatment combination. Surface preparation methods for concrete floors As a first step, all traces of calcareous salt, grime, oil and paint stains should be removed from the concrete floors to be treated. Next, all laitance must be removed from the floors. Laitance refers to a layer located on top of a concrete surface, consisting of water and fine sand known as filler, which rises to the surface while the concrete surface is being floated. When laitance hardens, it forms a dense but brittle layer. The laitance layer needs to be removed in order for the primer, which is used in the surface treatment of concrete floors; to be able to penetrate the porous concrete properly. Laitance can be removed either mechanically or chemically. An untreated concrete floor should be covered with protective covers during construction-phase painting and installation. This will prevent the need to remove oil or paint stains at a later stage.
14
Grinding Grinding is the most widely used method of removing laitance layers and other impurities. The process of surface grinding removes all fine laitance and other traces of weak surface layers from the entire floor area, revealing the fine-grained aggregate. Surface grinding can be regarded as a minimum requirement in the preparation of industrial facility floors. The process of in-depth grinding removes a floor’s surface layer from the entire floor area, revealing the coarse aggregate. Scarifying A concrete floor can be scarified using a pneumatic, electrical or internal-combustion driven milling cutter, which creates a rough surface and removes all of the laitance. This is a highly effective and efficient technique, especially for the removal of oily or grimy surfaces from old floors, and of coating films and peeling paint surfaces. When performed correctly, scarifying is carried out twice, with the second round being performed perpendicular to the first. The form and depth of the marks left by the milling cutter depend on the type of cutter (its steel type) used and the cutter’s depth adjustment. Different cutters are available for different surface materials. Hard metal cutters are normally used in the scarifying of concrete surfaces. Dust nuisance can be alleviated by using milling cutter devices connected to industrial extractors. April 2017
Shot-blast cleaning Shot-blast cleaning is one of the most efficient methods of removing laitance, grime and poor surface material. In shot-blast cleaning, steel pellets are blasted with huge force at the floor surface to be cleaned. By varying the pellet size and velocity, it is possible to adjust the efficiency of the cleaning process and the resulting surface profile. A shot-blast device is constructed in such a manner that all loose laitance, all dust and all steel pellets can be collected using an extractor. The device separates cement dust from steel pellets, which are recycled during the cleaning process until they themselves turn to dust and are deposited in the dust container. After a shot-blast cleaning operation, a separate vacuuming process is usually unnecessary. If the floor has deep potholes or cracks, shot-blasting may leave steel pellets within such fissures. Should this be the case, all pellets must be removed before the coating is applied. Shot-blast cleaning is practically dust-free. As a cleaning method, it is ideal for the removal of laitance from even, hard industrial cement floors. However, shot-blast cleaning may be too efficient for the removal of laitance from hand-floated cement floors. The surface profile left by the device could be too rough if the blasted floor is to be coated with only a thin paint or varnish coating. Shot-blast cleaning is also suitable for the cleaning of horizontal steel and asphalt surfaces.
Etching with hydrochloric acid During etching with hydrochloric acid, the laitance layer is dissolved in hydrochloric acid, forming a calcium chloride solution and sludge consisting of filler material and silicic acid. The resulting sludge is practically neutral. If the floor to be etched contains grease, oil, grime or a similar substance, such impurities must be removed using an emulsifying preparatory washing, before etching with hydrochloric acid is performed. Eng Charles Idowu the Technical Director at CoverTec Products insists that, the use of extremely small size (Nano) molecular technology in product formulations allows the production of ultra-thin water based coatings and surface treatments that bond covalently to the surface. “The results are sealers with much greater adhesion and increased durability when compared to conventional surface treatments,” he said CoverTec Products is a manufacturer of floor, roof and wall waterproofing maintenance products. “Using nanotechnology, we produce an ultra-thin protective surface layer that is low in VOC (low emission) breathable and extremely oil and stain resistant. Our sealers do not lift and flake like standard sealers and coatings,” said Eng. Idowu.

Why you need a Modern Showerhead M
odern showerheads not only offer the user the perfect combination between aesthetics and functionality, but also an enjoyable way to unwind and relax tired muscles after a long work day, or a rejuvenating on-your-toes experience first thing in the morning. Modern showers can deliver water in a variety of ways; from handheld to fixed showerheads, to oscillating and jetted sprays, or even a combination of all four. They are not just designed with personal hygiene in mind, but also with the aim of improving the showering experience to make it as enjoyable as possible. 18
In that case, they possess a number of options that alter the methods in which the water is delivered to the body, with systems like assorted massage options, full sprays, jet sprays, mist, rain-showers and waterfall simulations, as well as combinations of all of these to improve the showering experience. Water saving options A shower for five minutes uses about a third of the water used to take a bath, making showering a very eco-friendly option.

off switch, which allows you to stop the water flow while you are busy soaping up or shaving.” Installing a showerhead flow restrictor system is another excellent and incredibly affordable idea: It can save you thousands on electricity and water consumption every year. A flow restrictor can reduce the water flow by up to 1, 34 and 1, 66 litres per minute, depending on the pressure of the water. This in turn, will also serve to dramatically reduce electricity bills, as the geyser won’t be working overtime to constantly heat up the inflow of extra water. However, flow restrictors are not advisable for showers built in areas that experience low water pressure. You could also go for a low flow showerhead, which saves water but does not interfere with the power of the water flow. A low flow showerhead does not mean you will have a weak stream of water; these showerheads possess a built-in mechanism that converts a weak pressure stream of water into a high pressure stream by combining the water with air. Although less water is used, because it is combined with air, it occasions a high pressure misty spray. There are also low flow showerheads available that do not mix the water with air. These showerheads create a shower that delivers a strong massage-like effect. The disadvantage of showerheads that aerate the water in order to increase the pressure is that this practice also lowers the water temperature. As such, if you like really hot showers, and then it is probably best to avoid aerating showerheads all together. Water pressure It is quite essential that homeowners take their home’s water pressure into consideration before choosing a showerhead for their bathroom; since it is quite frustrating to take a shower where the water is literally trickling out of the showerhead. Today, there are plenty of designs that solve the low pressure problem, and there are some showerheads that need high water pressure constantly in order to properly function. Extra features Modern showerheads need to look good, have great durability and perform well; as such, many models provide a number of special features that will move your showering experiences to new heights. Flowadjusting dials: These allow you to control the water flow pressure in your shower. You can turn up the pressure for a deeper massage-type effect, or you can turn it down for a gentler flow. Showerhead filters: Built-in shower filters purify the water to ensure that you shower in the cleanest water possible. In addition to any potentially harmful bacteria, showerhead water filters also eliminate chlorine from the water, which has a negative effect on both your skin and 20

hair, making them brittle and dry. Using purified water to shower promises to improve the elasticity and complexion of your skin; and strength of your hair. Shut-off valves: These valves aid in switching off the water flow, literally pausing it; so that you can wash yourself, your hair or shave, before switching it on again to rinse. Anti-scalding protection: If the shower is used by small children or elderly people, it would be advisable to consider anti-scald protection. Replacing your old valve with a new one calls for some serious plumbing; however, you can go for an anti-scald fitting that can simply be installed between the shower arm and your new showerhead. Self-cleaning showerheads: The unique self-cleaning action of some modern showerheads removes clogging particles after each use. Ronelle Badenhorst Commercial Director at Kohler Africa mentioned that, the concept of showering has shifted to more than just a daily routine and is now viewed as an experience. “Older showerheads were designed on a very basic premise which ultimately meant the more water you use the better the experience,” she said. “While the extensive research done by the Kohler team highlights the importance of integrating technology in ensuring that the shower experience is generated through design innovations that still guarantee a shower experience comprising warmth, force and even distribution balanced again reduced water usage,” said Ronelle. “The inclusion of the Katalyst Technology in Kohler’s range of showerheads optimizes spray performance for maximum enjoyment while reducing water consumption. This innovative technology infuses 2.2 litres of air into 2.5 gallons of water resulting in a shower experience that awakens the senses through larger water droplets that stay warmer for longer, an invigorating forceful shower that ensures full coverage and minimal overspray,” she explained. “While the Kohler Racetrack Technology a patented design is aimed at delivering the right force of water, optimal coverage and minimizing wasteful overspray. Available in a range of design and size options the use of these technological advancements is integral in creating the ultimate BOLD Kohler Shower experience,” she added. According to Ronelle, the bathroom space has over the years changed so drastically from a mere room in a home to a space that is aimed at giving users an experience and an escape from the clutter of life. In line with this change some aspects consumers should bear in mind when purchasing bathroom products are: Efficiency – As we continue to deplete precious resources with no contingency plan it is important to buy products that guarantee optimal performance with minimal wastage and consumption Experience – If you are looking to create an experience it is important to purchase a product that sells a holistic solution with a focus on design innovation, technological advancements, superior quality and longevity. Aftersales – The trend in most sectors is simply supply and demand with little to no consideration toward after sales. It is crucial that consumers purchases good from reputable companies with a warranty as well as technical support systems in place. Francesca Zulian of Tender rain argues that, the current shower head trends look for unique design for the bathroom as well, which is no longer a room of secondary importance within the house.

Apex Steel Always a Step Ahead Apex Steel, the pioneers in the manufacture of Deformed Bars that meet international standards of BS: 4449 and conform to local ISO standards – Kenyan ISO 6935 – 2 ,are making inroads in the distribution of their Deformed Bars into the Kenyan retail market. With the new KEBS regulation, twisted bars will not be sold in Kenya with effect from 1st April 2017. This new directive will now ensure that even the smallest of structures will have the opportunity to be built with the steel that conforms to global standards and design. APEX TMX is manufactured under technical license from German Engineering. This high end process ensures the Deformed Bar Steel meets the highest specification of international standards. As a consequence of the consistency in the quality of the product manufactured and supplied, iconic sites, infrastructure projects, residential complexes and the independent home builder continue to subscribe to APEX TMX as it delivers against the promise of quality. The KEBS allowable tolerances are +/- 6% for D8mm and +/- 4.5% for the other sizes. Apex Steel is the only company that manufactures D 40mm in Kenya. This is essentially used for high rise buildings. Apex Steel prides itself in staying ahead by providing sustainable solutions for Construction and Engineering. APEX TMX is the only Deformed Bar that is ‘LEED’ (Leadership in Energy and Environmental Design) certified; making it the only steel in East and Central Africa that is ‘Green Steel’. The French Embassy is a Green Project where APEX TMX was used; moreover, other developers and consultants who seek materials for ‘Green Projects’ are also using APEX TMX. Apex Steel has another ‘first’ to offer: a facility that is not commonly available within the region. ‘Cut and Bend’ services on all the Deformed Bar sizes including the D 40mm can facilitate construction projects, saving time and money. Information available from Contractor experiences suggests that based on sizes and designs, the use of ‘Cut and Bend’ ensures the overall requirement of steel is reduced by approximately 11%. One can imagine the financial impact of this facility when high-rise structures are being built. More and more contractors are seeking this service that Apex Steel is able to offer within 48 hours precision ‘Cut and Bend’ as per the BBS (Bar Bending Schedule) delivered to site. Apex Steel has now pioneered the supply of Bartec Couplers for Deformed Bars. Couplers are an effective and an efficient alternative to the conventional ‘overlap’. This has several structural benefits on concrete compacting, transfer of load, integrity of the continuity, safety at the site and time savings due to speed of execution and savings of upto 15% in some of the Coupler sizes when compared to the overlaps. Some progressive developers and engineers have chosen to introduce ‘couplers’ for their projects in place of the conventional approaches. To read more and to comment on this story visit

SOLAR
Mix and Matching Solar Modules
I
t is a common question that is being asked more so in companies dealing with solar power systems. For instance, in a situation where a customer has an
assortment of modules they want to install in the same solar power system. They have a stockpile on hand that they want to put to good use. In some cases they may have an older solar power system that they want to expand upon or replace a few faulty modules that are now outmoded. The knee jerk answer seems to be ‘No way!’ Do not fret. Typically the mixing of solar modules from different

manufacturers and of dissimilar voltages, wattages and amperages is not recommended. However, if you take those factors into careful consideration you can easily achieve this goal. When mixing solar modules, it is important to remember that it is not the wattage of the modules that is important to consider. When connecting modules of dissimilar electrical characteristics in series, it is each module’s current that plays a heavy role in how the string is going to perform in the solar power system. The opposite is true of modules that are connected in parallel. In this case, each module’s voltage impacts on how the string will perform in the system. However, this does not mean that we should start connecting any mix of modules together and call it a day. When their electrical characteristics are too far apart the effect on the system’s production could be tremendous. Compare the module’s data sheets. Only modules with exact amperage, or as closely similar as possible, should be wired in series connection. On the other side of the balance that rule applies to dissimilar modules wired in parallel connection. Only in that case, the voltage of those modules must be matched as closely as possible. April 2017
The use of micros or optimizers is highly recommend if you are considering pairing dissimilar modules into one system.
Series and Parallel Connection Say you want to connect modules in series and one module type is 8A and the rest are 8.5A. The 8.5A modules will all be dragged down to the 8A of the module that is brought into the string. This in turn will bring down the overall output of the entire string. Now, let us say we have a 30V module that we want to bring into a 40V string where the modules are all in parallel connection. In this instance, the parallel modules are pulled down to 30V and reduce the overall output of the string. String(s) It is not all that cut and dry; however, there are other considerations to take into account before mixing your modules. For example, if the string(s) with dissimilar modules are connected to an MPPT channel on a charger or inverter, the MPPT control would not be able to optimize the string due to the different current or voltage.
Micro-inverters and Optimizers Finally, it is worth noting that the majority of mismatch production losses can be mitigated with the use of micro inverters or optimizers. These two technologies allow each module to be treated independently within the system, ensuring maximum production from each panel.The use of micros or optimizers is highly recommend if you are considering pairing dissimilar modules into one system.
Leading the Way in Thermal Imaging
Quantification Another factor to consider is that in older operating systems that are in operation where you want to mix in a different module, you cannot rely on the data sheet for the existing module. This is because of the expected degradation of these modules over their lifespan. Therefore, despite maybe having close electrical characteristics on datasheets, in reality these specs have likely have changed and this should be quantified before paring the new modules into the strings. Module alignment Additionally, if you are in a situation where you are considering mixing up your modules you want to ensure that your modules are very close in their electrical characteristics. For paralleled strings, try to match the module voltages as closely as possible. In series strings, match their ampere rating as close as possible. In either case, the lower of the two values will determine the production you can expect out of the solar power system.

700 In 2014 when Centum Investments Group set about the development of part of their 102 acres adjacent Nairobi’s exclusive surburbs of Runda & Rosslyn; it was a mission to transform some agricultural realestate teeming with coffee bushes, napier grass and the occassional jackal into one of Africa’s foremost commercial monuments. A watershed moment that defined the sheer ambition of Kenya’s real-estate sector! A top-tier project team led by m/s Boogertman + Partners Architects engaged gear to deliver the ultimate experience in retail, entertainment and lifestyle; giving rise to the largest mall in the sub-Sahara outside of South Africa.

circulation; an indipendent solar solution generating 2 megawatts of green energy… one could enumerate the hallmarks of this new revolution until the (2) cows come home! Amidst the glitz & glamour of uncorking champagne that heralded the official opening of the mall on the 3rd weekend of February 2017, a small army at Mabati Rolling Mills Ltd (MRM) was beaming in quiet satisfaction. Away from the pomp, MRM’s projects team had made 2 significant contributions to the project’s success. In the first instance, the project architects & the specialist roofing contractor, m/s Bells Associates Ltd (BAL) had, almost two years earlier to the day, challenged MRM to participate in crafting a suitable roof covering over the mall’s undulating internal street. The concept was a marriage of glass & steel that would protect the interior from
the elements whilst bathing it in glarefree, natural lighting. MRM’s Saflok700 concealed-fix roofing profile had been chosen for its unmatched long spanning, weather-tight and low-sloping abilities. But fitting the strongly angular, straight and bold Saflok700 over a jelly-like space was quite an ask! After days of exchanging proposals, the compromise was to ‘design each sheet’ both in size and placement and then weather-treat gaps at each change of orientiation using made-to-fit triangular cover-flashings. This daunting exercise would have been easier with project siteprocessing of Saflok700 which MRM usually provides that would have allowed crosschecks & adjustments for a perfect fit, minimized wastage & no site-rework. But as fate would have it, ongoing earth works rendered site-processing untenable! MRM & BAL now had to synchronize their checks & adjustments amidst numerous siteto-factory shuttles as works progressed.
Finishes works after MRM's Saflok700 & Glass Skylights were installed over the curving internal street.
Working through the 2015 Christmas period, they pulled all the stops to deliver outstanding results by close of Quarter 1, 2016. When a year later a hundred thousand souls thronged this new temple of commerce & entertainment, their eyes raised to the elegant skylights above their heads, the MRM projects team felt that the ultimate homage to the efforts of 12 months earlier had been paid. The new king-of-malls proudly wore his Saflok700 & Glass crown to thunderous acclamation! MRM’s second contribution to Two Rivers would come via a strategic partnership. The United Nations Environment Program (UNEP) recons that buildings use 40% of global energy, 25% of global water and 40% of global resources with the building sector as the largest contributor to GreenHouse-Gas (GHG) emissions! Designing a juggernaut like Two Rivers ‘green’ therefore called for ultra-sensitivity.

The energy capture happens via hundreds of solar panels deployed as podium level parking sheds on steel frames; shading parked cars underneath from the elements while the ‘roof’ generates enough energy to power 1,000 homes! This clever mix of solar-panels-as-parking sheds was sure not Kenya’s first, but the sheer scale at Two Rivers was far and beyond anything attempted; optimizing the dual mains-solar system using intelligent controls as per load demand. Remarkably, the installers project an investor’s payback period of only 8 years!

Digital Survey:
3D Laser Scanning
3
D Laser Scanning technology can be used in a wide range of High Definition Surveying (HDS) applications either alongside traditional survey instruments or as an alternative to total stations. A surveyor can quickly gather a huge amount of accurate co-ordinated three dimensional 3D laser points from the surface of remote feature as a ‘point cloud’ image, when using 3D Laser Scanning instruments; providing quick surveying solutions for complex geometrical detail and inaccessible elements. After the 3D Scanner has scanned a structure or site to form a definite high definition survey image, it is then processed with visualization and modeling software to represent the surface surveyed. The data gathered from the scanned image can then be utilized for a wide variety of applications like exporting to CAD in 2D or 3D models in wire frame or to other rendering software packages. This kind of surveying technology makes it possible for the surveyor to capture and utilize huge volumes of 3D data in a span of environments and is quite suitable for measuring heritage sites, historic buildings and facades along with applications in detailed petrochemical and industrial 26
environments. 3D Laser Scanners are also well suited for surveying projects like highways, tunneling projects or hazardous sites where traditional survey instruments may not be well suited. Added Confidence in Surveying A major potential advantage of a laser scan survey is that it can present more confidence in the survey results than those obtained from traditional survey equipment. This increased confidence comes from several sources which include: A higher density topographic survey is basically a more complete topographic survey. Some details that may be overlooked can be otherwise captured. Extra data can be deemed as ‘oversampling’ or added redundancy, similar to taking extra shots, double and triplechecking data and so on. High point density normally removes ‘guesstimates’ or the need to make assumptions on the geometry and relative spatial positioning of structures or objects. All captured measurements are specific measurements of the surface in question. No offsets or poles are used, so the worry about poles not being vertical or offset estimates being incorrect are removed.
3D visualization and Imagery ingrained in laser scan surveys can also present added confidence that the mapping results correspond to what was really there at the site. The potential for laser scanning to impart added confidence in a topographic survey’s results reverberates to the very core of the survey and engineering professions. One of the key reasons why surveyors are contracted over non-surveyors is that clients need results they can trust from an expert. This is also why a client may often choose one survey or engineering company over another or goes for one sub-consultant exclusively; the client trusts their work more. On the authority of Dave Beattie of Autobuild Africa, the impact of using 3D laser scanning for topographic surveys in mapping and planning is immense. “Laser scanners typically measure 10 000 or more points per second, as opposed to 1 or 2 points per minute which conventional survey instruments do. So Laser scans cover every centimeter of the ground, building, mine; giving much more detail and enabling much more accurate volumes to be calculated,” he said. “So we are talking about speed as well as accuracy improvements, plus providing much more detailed results,” he added. Autobuild Africa Limited is one of the leading distributors of levels, theodolites and surveying accessories. They distribute the equipment from South Africa to other African countries. “We carry forward our support to the surveying community with highly trained technicians that are able to repair, calibrate all makes of surveying instruments,” said Mr. Beattie. “Conventional surveying instruments are still essential for setting out of construction projects, but for data collection jobs, there is simply no comparison to 3D laser scanning,” affirmed Mr. Beattie. “Technology, especially software is developing at a rapid rate, so it is important for the consumer to shop around before buying any survey equipment. With the economy being relatively stagnant, companies are reluctant to spend on big ticket items. On the other hand companies need to remain competitive, which ultimately means they will have to invest in the latest technology, so we are optimistic for the future,” he said. The high density feature of laser scanning is its most basic, driving technical April 2017
differentiators compared to other methods of survey. Moreover, a laser scan survey also features ultra-fast data capture, 3D visualization, remote measurement, and informative imagery in addition to its high density feature. Collectively, a laser scan survey could be called an ultra-fast, high-definition, reflectorless topographic survey. This distinctive combination of features provides several main potential advantages over other methods of survey for detail, engineering, and as-built surveys; including the core potential advantage for the surveyor and engineer to enjoy more confidence in the survey results. Mr. Muya Kamamia the Managing Director of Measurement Systems limited argues that the efficiency of 3D laser scanning in survey cannot be refuted; however it has not been fully embraced in the Kenyan market due to its price. “I think we have only one distributor in Kenya who sells laser survey equipment,” he said. However, According to Mr. Wycliffe Abiero, Managing Director at Ramani Land Services, investing in 3D mapping systems is vital as the benefits accrued are many.“The systems are no longer as expensive as before but require a lot of skill and practice to get the gist of it and do much more. They come in different forms but the product is usually the same. Depending on what you really need and how accurate you need it, will inform what you need to go and shop for. If you want to map inside a structure, you will not go for the aerial LiDAR system which is much expensive, you will for the unmanned system which is slightly cheaper. But if you want to map an entire city, you will go for an airborne system because of its size,'' he said. ''Therefore, the price will always depend on the specifications you really want to achieve,'' he added. Ramani has a great team of surveyors, GIS specialists, photogrammetrists and support staff, coupled with latest surveying technology; all working together to provide the client with an exceptional experience. Their solutions range from Aerial Photography and LiDAR Surveys, satellite imagery, land survey, as well as GIS and Mapping, and are tailored to meet project requirements for various applications. “LIDAR system highly thrives on higher accuracy. Acquisition of data is so fast; the system is able to collect over a million points per second. Moreover LIDAR systems require only one person to operate the equipment unlike conventional systems which need a surveyor and a support staff on hand,” said Mr. Abiero. “Additionally, with LIDAR systems mapping can even take place at night. Due to their active nature, they do not depend much on light,” he affirmed. “We have got the system but to build up a product is not that easy because the local market has not changed. People using the data have not transformed their systems to start consuming the new technology. The collector of the data has transformed but the end user has not transformed. In that case, there is the need to train the recipient of the data on how to consume the new technology before they can embrace it,” he asserted. April 2017

STANDARD GAUGE RAILWAY (SGR) Beyond the Rail
O
ver the last two years Kenya’s infrastructure focus has dwelt predominantly on the construction and completion of the Standard Gauge Railway (SGR) which will revolutionise both cargo and passenger transport. The first Phase of the SGR which the largest infrastructure project under Vision 2030, is now 98 per cent complete necessitating a shift in conversations around the project. The project which is being constructed by the Kenya Railways under the supervision of the Ministry of Transport, Infrastructure, Housing and Urban Development has been touted as an important transformational project for the railway and entire transport sector in the region. Operations on the line lead to unlocking of the transport gridlock that has seen demand for transport outdo the existing road and rail network capacity in the country by far and the cost of production rise to unmanageable levels. During its construction phase, the SGR project has driven economic and social development in Kenya, in line with the key objectives of Vision 2030, underlining its pre-eminence as a Vision 2030 flagship project. The project’s construction phase has created thousands of employment opportunities for locals making SGR one of the biggest employers in Kenya outside the Government. Local companies have also been able to reap big from SGR local content inclusion which has seen Kenyan suppliers plug in at different levels of the project such as: provision of transport for the employees to the various project sites along the line; subcontracting of civil works; equipment leases; and security. This has gone a long way in ensuring compliance with local content laws, which stipulate that at least 40% of Inputs utilized on the project should be sourced locally translating to approximately 130.8 billion. Moreover, a considerable number of Kenyans have benefited from skills transfer in specialized fields such as engineering and production. This has not only enriched the skill set of individual Kenyans, but also substantially improved the quality of human capital in Kenya to globally competitive levels. The Kenya Railways has already began building the capacity of locals to operate the SGR with 748 railway technicians already trained in management of various
components of operating the Standard Gauge Railway line at the Railway Training Institute (RTI). The Institute is also set to be upgraded with the government set to invest over Ksh. 2 billion shillings in the modernization of the Institute. RTI is just but one of the avenues being used as a critical tool for technology transfer With implementation of Mombasa to Nairobi section at an advanced stage, there is no doubt that it will be finalized within schedule. Kenya is now transitioning into a new chapter of its growth trajectory, a chapter that will be increasingly characterized by the powerful role that the SGR line will play in shaping positive economic outcomes. Manufacturers will, for instance, be able to reduce the cost of sourcing inputs, lowering the overall cost of doing business and allowing them to remain competitive in both the domestic and regional market. The expeditious implementation of SGR is therefore a positive development for manufacturers and the broader business community. The SGR is designed to carry 22 million tonnes of cargo annually or a projected 40% of Mombasa Port throughput by 2035. This will reduce congestion at the port of Mombasa, positioning it as the preferred port of choice in the region. Along the same lines, the SGR line is also expected to immensely supplement road transport, thereby reducing congestion as well as the cost of road maintenance caused by wear and tear. Fewer trucks on the road also reduce carbon emissions, allowing the country to play a proactive role in mitigating against growing global challenge of climate change. The SGR is also expected to significantly cut the cost of rail transport in Kenya. It is projected that the SGR will slash the cost of rail transport by a staggering 75 per cent from $0.80 a tonne to $0.20 tonne. The implications for businesses in import and export are profoundly immense. The consensus among economists is that the SGR will add at least 1.5 per cent to GDP growth each year. The SGR will therefore burnish Kenya’s already glimmering profile as a regional trade hub, providing necessary impetus for sustainable GDP growth. Much like its over 100 year old predecessor, the SGR line will therefore play an important role
in revitalizing economic activities especially in areas traversed by the line creating both national and county level business centres that will in turn create additional jobs and opportunities for wealth creation. Upon its completion the Nairobi Mombasa Line which stretches across 472 kilometres will host 33 purpose built train stations. Of the 33, 24 will be crossing stations enabling the seamless crisscrossing of trains along the line and enable at least 15 trains to occupy the line at a given time. To operate the line the government has procured 56 locomotives powered by diesel engines. 43 of the locomotives will be used for freight while 5 locomotives will be designated for passenger operations with the remaining 8 dedicated to shunting purposes. The passenger trains will hold a capacity of 1,096 passengers and will move at a speed of 120 Kph cutting the total travel time between Nairobi and Mombasa to 4 hours 30 minutes inclusive of the stops at other train stations. Freight trains allow for double stacking of containers thus increasing the lines haulage capacity. A single train can pull 54 wagons with two containers stacked one on top of the other. The total capacity of 216 TEUs and a total tonnage of 4000 tonnes per train. The freight trains will travel at 80Kph and take 8 hours 10 minutes between Nairobi and Mombasa. The China Road and Bridge Corporation (CRBC) has been retained by the Government of the Republic of Kenya to operate the line for a period of ten years as the country undertakes initiatives to build capacity locally. Throughout the period CRBC will be required to dedicate resources to foster technology transfer to enable more local railway personnel to eventually take up operation of the line. Qualified local railway engineers will be absorbed into the CRBC’s operations gradually phasing out foreigners and replacing them with local manpower. With the construction of the Nairobi Mombasa line on course for completion by June 2017, focus is set to shift to the construction of the 120 Kilometre Nairobi Naivasha line under phase 2A of the project. The line is set to be completed by 2021 at a cost of Ksh. 153 billion.

oogertman + Partners Architects was established in 1982 in South Africa and currently has 250 employees. The firm entered Kenya in 2012 by establishing a subsidiary. Notably, the firm was not venturing into a new market because it was already engaged in some projects. Led by Johann de Wet and Andrew Kusewa and complemented by a pool of talented professionals - urban designers, interior designers, architects and technicians, as well as an in-house graphics team, this small firm has started making bold moves in the Nairobi market and even skyline. The birth was driven by strong intentions to tap the East Africa market which is witnessing an unprecedented growth in the building and construction industry, Boogertman + Partners decided to set up a fully-fledged practice in Nairobi as opposed to flying in and out of the region with a laptop, in the words of de Wet. Over the last decade, Kenya has experienced a real estate boom with prices rising rapidly amid high demand from both long-term investors and speculators. According to the Economic Survey 2016, the building and construction industry registered a growth of 13.6 per cent in 2015 compared to an expansion of 13.1 per cent recorded in 2014. Boogertman and Partners Kenya has grown to deliver projects to completion ranging from retail, commercial, industrial, offices, hospitality, education and residential fields.

PROJECT
the capital city. RUPA’s Mall is an investment by the one of the largest textile manufacturing companies in East and Central Africa. According to Ravi Shah, the Finance Director, the idea of putting up a mall in Eldoret was driven by a desire to provide a one-stop shop for residents of the town and neighboring areas. “Eldoret lacks proper services,” he says. “There are only a couple of supermarkets. You cannot even find a cinema here; which is why we decided to bring all these services under one roof.” Ravi estimates that at peak hours, the population of Eldoret reaches nearly 1 million people. It is this vast population that RUPA’s Mall intends to cater for. By all standards, the development is massive and one may fail to appreciate the magnitude of the project without a visit to the site. The front and rear parking area will accommodate about 500 cars. Water features begin right at the lobby and will be part of the biggest attractions. The large children’s water park is set adjacent to a soon-to-be lush green garden that will provide opportunities for relaxation and can also host functions such as wedding and other social events. The entire recreational area sits on at least 3.5 acres. 42
The twin towers on either side of the complex protrude into the sky providing breathtaking views of Eldoret and the surroundings from the top. One tower hosts the hotel while the other houses offices, shops and other businesses. The architects have created an atrium to improve aesthetics, air circulation and natural lighting. RUPA’s Mall will feature a perforated aluminum façade. According to Ravi, behind this façade will be a special lighting that will be remotely controlled to light up the frontage; meaning that management can change colours depending on the season. Imported porcelain and granite tiles will be used in the building which will also exclusively use LED lighting to save on energy costs. The building will be served by 10 ultra-modern lifts as well as escalators, making it truly the first state-of-the-art commercial development in Eldoret. A standby generator will be installed to ensure steady supply of power. The entire development is ringed with a perimeter wall for easier provision of security. The mall, designed by Nairobi architect Satish Shah and his Spanish counterpart Francisco Ortiz Luna who is the interior
designer for the mall, is located right on the town’s main road (Uganda Road) as you approach from Nakuru. There are also plans to make the mall accessible from Elgeyo Road for the convenience of patrons approaching from that side. Construction works began in March 2015 and the mall is expected to be open by September this year. The current works are at about 85 percent complete with the main structure already complete.
