ENVIRONMENT

Reducing Carbon Emissions As a leading producer of high quality cementitious material, AfriSam is ideally positioned to support customers seeking to reduce their carbon footprint while insisting on superior building material.

F

or over half a century, AfriSam has produced its trade-named ‘slagment’ from ground granulated blast furnace slag (GGBFS), according to AfriSam cementitious executive Hannes Meyer. “We have used this latent hydraulic binder in an extensive range of concrete applications, including major structures such as dams, bridges and roads,” says Hannes. “Indeed, it is only very specific and limited applications that today demand our cement without added slag.”

Green Credentials

He highlights the self-cementing properties of slag, which can double the lifespan of buildings. Among its key benefits, however, is to prevent sulphate attack and alkali-silica reaction in concrete, especially in applications like wastewater treatment plants, or where there is seawater or sulphate-rich soil. “However, there is now an added consideration in business today, as companies anticipate the impact of the new carbon tax,” he says. “Slagment assumes a significance here too, as it reduces the amount of clinker in concrete, and cutting the Hannes Meyer, cementitious executive, AfriSam

energy consumed and carbon emitted in its manufacture. The use of slagment therefore presents not just a technical solution but an opportunity to achieve higher environmental standards.”

Fine consistency

AfriSam’s dedicated slagment plant in Vanderbijlpark has the capacity to produce over 800 000 tons of slagment a year, along with over 200 000 tons of blended cementitious products. The slag is a by-product of the steel and iron industry, and the plant mills this to a fine consistency before blending.

The use of slagment therefore presents not just a technical solution but an opportunity to achieve higher environmental standards “As part of our sustainability journey, we have implemented various strategies in response to the energy-intensity of the cement manufacturing process,” says Hannes. “Slagment remains a vital part of this journey, and we continue to develop innovative ways of extending its benefits to customers.” Another important capability of slagment is to reduce the thermal heat gradient generated when pouring concrete. This reduces the likelihood of micro-cracking, which may weaken the structure’s strength. Slagment can also alter the colour of concrete to near-white by replacing 50 to 70% of the concrete, giving the concrete a better appearance. In addition, it produces a smoother, more defect-free surface. AfriSam Hannes Meyer Tel: (011) 670-5500 Email: customer.service@za.afrisam.com www.afrisam.com

COVER STORY

Casement to Curtain Wall HBS (Hulamin Building Systems) has the largest and now the only SANAS accredited test rig in South Africa. This makes the company an accredited ISO 17025 laboratory for testing its products in line with SANS 613.2011. 2 100 to 6 118 sample sizes up to 3m wide x 6m high can be tested at pressures from A1 to A6.

T

he rig’s capabilities also include water resistance testing from 200 to 700 PA, deflection (positive and negative) from -3 500 to +3 500Pa, and structural proof loading from 1 500 to 5 250Pa. Says CEO Ronnie Mazor, “Achieving ISO 17025 is no easy feat as the requirements are pretty rigorous. Maintaining the standard is equally onerous. For example, the air flow meter has to be checked in Germany, pressure gauges must be sent to the UK and not just anywhere in the UK or Germany either.

The result is that our customers save money as they do not require the signature of a professional engineer “These measures are expanded with control samples, control visits and proficiency testing every 60 days. We are certainly held to account but the result is that our customers save money as they do not require the signature of a professional engineer. “Our personnel have been declared competent and approved as technical signatories by SANAS. This means our test certificates are legally acceptable.”

In the world

Not one to stand still, the company claims to offer the simplest and strongest curtain wall waterproof system in the world with pressure and flush glazing performance tested to A4. Curtain wall profiles range from 200, 250, 350 and 450 off the shelf and, with a range of custom manufactured brackets.

Transom holes can be pre-machined for on-site installation or at the factory offering greater flexibility to an already slick system incorporating fewer parts and minimal machining for easier fabrication. “The user is able to install any transom at any time and in any order as no sequence is required. For instance, the installer can deliberately omit one section and then install later with no loss of efficiency. “An additional bonus is that the system is designed to reduce the amount of silicone required,” adds Jim Jorgensen, a mechanical engineer (MSc) at HBS.

Offer the simplest and strongest curtain wall waterproof system in the world with pressure and flush glazing performance tested to A4 Dramatic improvement

Relatively new to the HBS line-up are louvres and shutters. Curtain wall louvres at an overhang of 600 – 2 400 can be retrofitted and sustain a wind load up to A4. Shutters come in one profile for the bottom and the top tracks. Standard 700 rollers are used on the tracks and pre-machined wall brackets make for quick installation. “What really distinguishes us here is the pneumatic punching tool resulting in a dramatic improvement in productivity,” says Ronnie. Another first from HBS is the Explorer system which has been designed to accommodate inside glazing, which allows fabricators to go as high as they want without the need for scaffolding. An ideal product for refurbishment projects. “All our products and systems are underpinned with what I can safely say is the best estimating software on the market,” Ronnie concludes. www.hbs.co.za

PRACTICE PROFILE

Tim Johnson

A

t 33, he’s accomplished a fair bit, especially if you take into account the years spent overseas working, teaching and travelling. “Architect & Specificator” caught up with him to find out more.

Tim grew up in Edenvale and studied at Wits where he completed his BArch. Not convinced he wanted to be an architect, he set off to explore the world. “My agreement with my parents was that I would go straight to varsity from school, and then travel for a while,” he shares. Tim found himself in Dublin, Ireland doing some work for Freyer and Taylor for six months. “It was really interesting sitting in on the meetings and taking notes when half the conversation was in Gaelic! But I really enjoyed it,” he says.

Back and forth

Tim then spent a few months backpacking in South America. “I was kind of on the fence on whether I should come home or not. Having arranged a cultural visa for Canada, I headed north.”

It was really interesting sitting in on the meetings and taking notes when half the conversation was in Gaelic In Vancouver, Tim worked for Took Engineering for a year, followed by more travelling in South-east Asia, before returning to South Africa. “It was 2008 and there were no jobs, so for about six months I worked as a night chauffer for Good Fellas,” he tells us. When a friend left for Taiwan to teach English, Tim went along, spending another year abroad. “I learnt some skills I never thought would apply back home, but you have to think on your feet. Skills I use today. I taught children from young ages up to teenagers.” After another traveling stint to Asia, the Philippines and India, Tim applied for his masters, was accepted and headed home.

So much opportunity

“While I was away I saw and met people in different cities and buildings and became more interested. I was young when I studied, but after being overseas I realised you just have to go with it, try it and see what transpires,” he says. “One of the biggest take-aways from my travels was the realisation that there is opportunity aplenty in South Africa. There is so much that can be done and developed here.” Tim’s first architectural job locally, after completing his masters, was with Imendulo Design Architects in the Eastern Cape. “I had family in Cape Town, Durban and Joburg – everywhere but where I was. I didn’t have any intention of coming back to Edenvale, but my dad saw a business on-line, Alchemy Architects, and told me to check them out. “I put my name on their landing page, not expecting anything but sure enough they replied and a couple of weeks later offered me a job.

Not convinced he wanted to be an architect, he set off to explore the world “Until then, I had worked for smaller businesses on smaller projects. Alchemy had a lot of motor dealerships, which were bigger than what I was accustomed to. It was a bit of a shock to the system.”

Good relationships

Tim spent two and a half years at Alchemy, until the middle of 2016 when owner, Amandio Castanheira, decided to move to Australia. Tim and those working at Alchemy had a choice of carrying on with the business or looking for other jobs. He chose the first option and set up Sage Architects, taking over most of Alchemy’s client base. “We do a lot of work in the motor industry. I wouldn’t have said this is what I would be doing after varsity but I really enjoy it and it suits me,” Tim adds. “One challenge is that we don’t do a lot of work in Joburg. Supervising from a distance means we have to cement good relationships with the contractor while communicating clearly and openly. We’ll do inspections every second week.” The practice has completed projects across South Africa and in neighbouring Gaborone.

Best projects?

Tim rates some of his best projects as those where the client is on a shoestring budget and “you have to make it look good.” “We did one such project in Macgregor, a small town in the Western Cape. The clients were old and the son wanted a cottage on the property he could stay in when visiting. The client was so happy, and it was so pretty that they use it as an Airbnb!”

Dream job?

“Taking care of the elderly. I think this is a big challenge. On the one hand it makes sense to have people together who need frail care, for example, but is it not better to live with people of all ages?” Sage Architects Tim Johnson Tel: (011) 609-1236 Email: office@sagearchitects.co.za www.sagearchitects.co.za

LESOTHO

Building in Extreme Environments South African architects working in urban areas do not have to spend a considerable amount of time paying attention to the natural environmental conditions. Sure, orientation is deliberated on, thermal efficiency is discussed, but in how much detail?

A

rchitects Of Justice (AOJ), in one of their first projects, had to learn very quickly how to design for extreme conditions. The project in question is Gondola Café, situated at the foot of the ski slopes of the Afriski Mountain Resort in the unspoilt natural setting of the Lesotho Maluti mountain range.

It’s extreme with the resort at 3 222m above sea level, so UV is harsher “We are all avid snowboarders and became involved in Lesotho through Club Maluti, a social club established in 1968,” explains AOJ’s Kuba Granicki. “There was first a directive by our client to build a clubhouse, on the slope for the Snowboarding Club of South Africa, and nearly at the same time they also wanted to add better facilities on the slope and to bring a certain

element of hype for visitors. “Gondola Café came out of those initial discussions. Our first proposal was design, concept and presentation in four days. We had practical completion of the building four months later. It was a ridiculous timeline due to the cold season fast approaching, and with very little money.”

No easy build

“It’s not an easy place to build,” adds AOJ’s Alessio Lacovig. “It’s extreme with the resort at 3222m above sea level, so UV is harsher, Lesotho is also the ‘water tower’ of South Africa, so the annual rainfall is very high. It can be freezing cold one day, and very hot the next, and if you run out of nails, there is no hardware store around the corner.” All these, and other lessons had to be taken on board and processed by the then young practice very quickly. “We were lucky, being snowboarders,


that we had all been on at least one international snowboarding holiday, so in our personal lives we had been exposed to the designs of such facilities,” explains Kuba, “yet your university studies don’t prepare you for implementing the necessary alpine design for what is classed as an Afro Alpine condition.”

fired fireplace. “The building works so well that we only used single glazing windows, and some nights they have to open the doors to let some of the heat out,” says Alessio. “It’s a very easy environment to control and regulate because the envelope is so efficient.”

The architects had several immovable structures on site which they had to design around, a ski lift, ablution facilities and a dam. “At the time we had to future rationalise a site development plan for the slope side of the resort, and ten years later we are now seeing those original concept development drawings coming to fruition.” Since Gondola Café, AOJ has completed four other structures at the resort, the snowboarder’s clubhouse, a timing hut, the ‘cooler box’ (an outdoor tuckshop) and a control tower.

Thermal efficiency is aided by the use of polyblocks, pretty much big polystyrene Lego blocks

Back to first principles

For Gondola Café, AOJ relied on the first principle designs which they learnt in university, for instance, the north side of the building features as little wall as possible to maximise on sun exposure. To additionally control the temperature in the high volume space they introduced a wood

This thermal efficiency is aided by the use of polyblocks. “They are pretty much big polystyrene Lego blocks filled with concrete, which gives you an easy to assemble permanent shutter that also works as insulation,” explains Alessio. “We cut insulation where we needed the services to run and then cladded the polyblocks on the outside with fibre cement board, painted to look like timber because of maintenance and costs, he concludes.

MIXED SPACES

Making its Mark One of Paragon Group’s first projects for an international hotel chain is the Mbabane Hilton Garden Inn in Swaziland. This 124room, eight-storey development in the heart of the capital has been designed specifically as an iconic building for Hilton’s entry into the Swaziland market, according to project architect, Jarred Pincus.

S

ituated up against a hill to the south of the city centre, the building and its landscape deck provide unobstructed views across the valley towards the city. This prominent location, combined with the design of the building, gives the hotel presence a unique in the urban context of Mbabane.

The main spaces of the

July/August 2019

hotel have been designed to create vertical separation and privacy between public and private or guest amenities. The iconic tower portion of the building, with its swooping and undulating feature façade, is architecturally differentiated from the base of the building, and is solely dedicated to hotel guestrooms and hotel facilities.

It isn’t specifically green star rated and designed, but standard best practices have been applied Public areas on the ground floor include a reception, restaurant, bar, lounge, and conferencing facilities comprising four meeting rooms of varying


sizes, with two of the larger rooms separated by sliding-folding doors with the flexibility to become a single large conference room. Reception and the main hotel entrance are located adjacent to the on-grade, on-site guest parking, where guests are greeted with a portecochere entry. The main guest parking is located to the rear of the site, while additional parking is provided in an existing parkade close by.

The iconic tower portion of the building, with its swooping and undulating feature façade, is architecturally differentiated from the base of the building The entrance to the building is reinforced by a full-height internal atrium that forms the central and primary focus space of the building, overlooked by all the guest-room corridors. The central atrium, which houses the restaurant, bar, lounge, and conference break-out facilities, also features skylights. These spaces also link to the ground-floor landscaping and deck spaces via two large sliding folding doors.

Gateway

“The client’s head office is adjacent, so this is always meant to be an iconic gateway to Mbabane. They wanted something that stood out, and it is definitely one that cannot be missed,” Jarred highlights. The main feature is the performance-rated façade design with varying sized windows, depending on the orientation. There is also a landscaped deck on the ground floor with trees and indigenous planting to cool down the building. “It isn’t specifically green star rated and designed, but standard best practice has been applied,” Jarred concludes.

HI-TECH DOORS AND WINDOWS

A Germ Free Environment Production in a controlled or clean room environment is common practice in many industries. All content within these contained facilities must adhere to strict hygiene and safety regulations. Doors which play a pivotal role in the prevention of air-borne contaminants entering the clean area, are certainly no exception.

M

axiflex was recently contacted by one of the largest pharmaceutical manufacturers in the southern hemisphere to provide an appropriate entrance system for their clean room facility in the Eastern Cape. Maxiflex understood that, in line with the pharmaceutical customer’s requirements, the door solution had to deliver optimal performance and meet all the stipulated hygiene and safety conditions.

The cables are located in the side columns to provide a smooth surface which facilitates easy cleaning

The RR300 Clean is equipped with a MCC frequency converter control system which supports a wide range of speeds, effectively keeping particle emissions and air exchange to a minimum The solution

“The RR300 Clean Room Door, with its quick opening and closing speeds of up to 1,2m/s and 0,5 m/s respectively, combined with excellent sealing capabilities, ticked all the boxes making it the ideal solution for this high containment facility,” says Guy Cooke, general manager of Maxiflex Eastern Cape’s Port Elizabeth branch. The RR300 Clean is equipped with a MCC frequency converter control system which supports a wide range of speeds, effectively keeping particle emissions and air exchange to a minimum, lowering filter burden and reducing energy consumption through efficient interior climate control. The smart cable guide sealing provides enhanced air-tightness and keeps the pressure drop to a minimum. The door consists of a PVC Curtain certified by the Fraunhofer Institute and according to Guy, is the first door to be tested and confirmed by the Fraunhofer Institute for cleanroom suitability. The cables are located in the side columns to provide a smooth surface which facilitates easy cleaning and avoids the accumulation of particle deposits and surface irregularities that may increase particle turbulence. The door is also equipped with a UPS battery for independent power supply.

Safety first

Placing safety at the forefront of design, the RR300 Clean is created according to the workplace directive of the UVV regulations and the harmonised

CE Guidelines including the EN 13241-1. Further improving on safety measures, the door contains a door line photocell which prevents closure when an object is in the doorway and features an electrical safety contact edge.

talian experts provided the pure cast acrylic blocks for underwater use, and Martin Muller, contracts manager at Concor Buildings explains that one of the first challenges during the project was the logistics of getting these large acrylic panels into place.

No easy task

“The panels were shipped in two pieces, each measuring five metres in diameter and four metres high,” Martin explains. “With each item weighing about four tonnes, they were transported in jigs and trolleyed into the confined space of the shopping centre.” To create enough space to access the lower level, one of the shopping centre’s escalators was removed completely to facilitate access for the trolleys. A spider crane, positioned on the food court level above, was used to lift and position each panel. The weight exerted by the crane’s activities was considered during this operation, with back propping of the slab on which it rested being done.

Various other technicalities related to the CrestaAquarium’s operation were also attended to by Concor Buildings. This included two pump rooms and acclimatisation baths for the fish their being introduced to their new home.

During construction, white insulation material around the structure was installed, viewed here from the food court at Cresta Shopping Centre

“After establishing the cast concrete base for the structure, we also installed service ducts for water reticulation,” adds Martin. “Another important aspect was the pressurised extraction system used to prevent dust ingress.”

Windows not glass

The thick retaining windows of the CrestAquarium are not glass at all. Supplied by Italy-based specialists, the windows comprise pure cast acrylic blocks, specifically produced to withstand immense pressure in underwater environments. The material is noted for its transparency, brightness, lightness and ability to resist ageing.

More Efficient Wall Production A wall shuttering system makes precast wall production more cost-efficient, needs half the amount of wood normally required and reduces wood wastage. The FaMe is suitable for table moulds, battery moulds, and column as well as pillar production. The system comprises push-button magnets and aluminium side forms and comes with benefits including cost-efficient production and safe working methods.

B

y installing the side profiles with magnets that are easily attached and removed from the table surfaces, the need for welding, bolting or grinding is eliminated, hence table surfaces will remain in good condition and numerous panels can be produced without any damage. Also the same frame system can handle most wall thicknesses from 70 – 500mm.

Improved quality

With wooden profiles, it’s likely that the panels will not come out all that straight, because of the challenges faced with wood and water. Everyone who is familiar with using wood side forms, knows how hard it is to get wet wood straight and in a 90˚ corner.

Safe and easy to use

The magnets and side forms are extremely easy and safe to use compared with other shuttering systems. Less finger injuries will occur because the push-button and the housings of the magnet have been designed to give a smart cover against any injuries.

By installing the side profiles with magnets that are easily attached and removed from the table surfaces, the need for welding, bolting or grinding is eliminated The FaMe system also makes it easy to prepare the edges and window or door openings on tables or battery moulds, as the side forms are simply placed in the desired places and are attached to the mould with push-button magnets. Users can easily move the magnets by sliding them on the surface before pushing the button for attachment. Elematic Oyj Nina Lehtonen Email: nina.lehtonen@elematic.com www.elematic.com/en

n 2004, when the CEO of the Southern African Institute of Steel Construction (SAISC) visited Australia to evaluate light steel frame building, this construction technique was little-known in South Africa. Today, this relatively new building method is now both widely accepted and frequently used locally. “The growth in the popularity of LSF construction locally is due to its inherent innovation, and to the fact that it reduces building costs, in a number of ways,” explains John Barnard, Director of the South African Steel Frame Association (SASFA), a division of the SAISC.

Less time taken

John explains that a major advantage of LSF building is that a structure takes much less time to complete than a similar brick and mortar building. “As the construction team can finish the outer shell of the building in a much shorter period, work on the inside of the building (completing internal lining, ceilings, tiling and painting) can get underway much earlier, as can the installation of services like water and electricity,” he points out. In addition, having the outer shell completed earlier means that the building can be secured against unauthorised access much sooner.

The growth in the popularity of LSF construction locally is due to its inherent innovation, and to the fact that it reduces building costs, in a number of ways “LSFB should however not be confused with prefabricated building. In LSF building, the supporting frame is made from thin gauge, highstrength galvanized steel sheet, which has been cold-formed into lip-channel sections. These sections are joined using rivets or self-tapping screws to form strong wall frames, roof trusses and floor joists,” he advises. The wall panels are then clad using fibre-cement and gypsum boards, fixed using battery powered screw guns to install the self-drilling screws. Insulation is installed in the wall cavities to provide thermal efficiency and enhance the acoustic properties of the walls. As far back as 2013, McDonald’s built an outlet in Cape Town which employed LSF in its con-

struction. In this project, material wastage was reduced by 30%, transport costs by 80% and the carbon footprint was significantly reduced. The savings on construction time were of such an order that McDonald’s was able to open the outlet four months earlier than expected.

Energy efficiency increased

With its installed insulation, LSF buildings are more energy-efficient than heavy masonry buildings. A research project carried out by the Council for Scientific and Industrial Research (CSIR) for SASFA, indicated that an LSF building will require less than half the energy needed to heat and cool an uninsulated masonry residential building.

LSFB should however not be confused with prefabricated building “The use of LSF allows for energy conservation on two levels. The energy used in the manufacture of the actual building materials or the embodied energy is considerably less than the amount consumed by traditional building materials. Secondly, the operational energy used in heating and cooling the building over its lifespan is also considerably less. “In addition, a LSF building is dimensionally far more accurate than masonry building or concrete construction. This saves time and cost when installing pre-made components such as kitchen cupboards and wardrobes. “With light steel framing, one can work to a tolerance of less than +5mm,” concludes John.

ALTERNATIVE ENERGY

Renting The Sun Viman Singh of Ice Cash & Carry in Ballito is smiling on sunny days as the store now harnesses the power of solar energy. SolarSaver installed a 50kW grid-tied solar photovoltaic (PV) system at the store which now powers 80% of its daytime energy needs.

L

ance Green of SolarSaver explains that while solar should be a go-to option in South Africa, with more than double the solar radiation output of Europe, the set-up costs can be prohibitive. However, backing from the PembaniRemgro Infrastructure Fund (PRIF) and Stimulus Investments has enabled SolarSaver to counteract the capital investment issue by offering a fully financed rent-to-own model.

No installation costs

“Business clients like Ice Cash & Carry do not have to fund any of the capital required to install the system,” says Lance. “Instead, the business rents the system from us and

will only pay for the electricity the system provides at rates significantly lower than municipal ones. We will also remain responsible for all ongoing installation, monitoring, maintenance and insurance of the system.”

The company will remain responsible for all ongoing installation, monitoring, maintenance and insurance of the system Currently, solar energy works well for many businesses via this grid-tied solution that focuses on daytime power generation, in an effort to reduce monthly electricity costs. Unfortunately, solar on its own doesn’t protect against load-shedding without the inclusion of substantial battery storage, which can be expensive. However, with the system in place, Ice Cash & Carry is able to take a phased approach to bringing batteries into the system. “We are currently logging the energy consumption of essential tills and lighting in order to fit batteries to operate these elements. Eventually, this system will be capable of taking the site completely off-the-grid,” Lance concludes. SolarSaver Lance Green www.solar-saver.net

Combining Natural and Artificial Light Office lighting has to be flexible, save energy, be controllable, and also make the most of daylight. This is because improved workplace lighting, in terms of both natural daylight and artificial light, has been linked to a 15% reduction in absenteeism in office environments. Related studies have reported productivity increases from 2.8% to 20% attributable to optimum lighting levels.

This ranged from operational (white light) to ambient conditions (natural lights) in the collaborative spaces and other private and breakaway areas. The lighting installation is also future-proofed in that it has been integrated into the Building Management System (BMS).

to. Pendants were also incorporated, especially in the collaboration areas, which served the dual purpose of lighting and providing acoustic properties. All the lighting is LED for maximum energy-efficiency, including feature lighting in the form of LED strip lighting. “The lighting intent was to supplement any shortfall from the natural lighting. There is a lot of glazing on the building, which admits a great deal of natural light. Hence it was just a matter of determining where this infiltrated to the required level,” Trend Group Technical Designer, Nicola Bridge explains. Motion sensors control the lighting, switching on and off automatically whenever there are occupants in an area. Automatic blinds were installed on the ground floor, front-of-house, and restaurant areas, with manual blinds on the upper levels. “We collaborated closely with the lighting engineer.

The lighting intent was to supplement any shortfall from the natural lighting All about comfort

“It all links back to comfort, and ensuring people are comfortable within the workspace, without suffering eye strain or either being over-stimulated due to the lighting,� Nicola highlights. In architecture this is termed biophilic design, which incorporates natural materials, natural light, vegetation, nature views, and other experiences of the natural world into the modern built environment. It has been reported to reduce employee stress levels, enhance creativity and innovation, and improve general well-being.

Such trends are becoming increasingly relevant, especially considering that employees spend 90% of their time indoors. Biophilic design goes far beyond merely adding pot plants to an office environment, but requires architects and interior designers to incorporate natural elements wherever they can. The impact on lighting in office-space design has been an increased use of daylight, in addition to the use of softer or accentuated lighting. This complements the latest trend of agile or shared workspaces, which have replaced the traditional windowless cubicles with fluorescent lighting.

“Furthermore, we have introduced our flexi suites, semi-serviced office units catering for tenants as small as 15m², in an upmarket and affordable corporate environment,” says Grant Silverman, marketing and leasing director at Abland. Located along Corobay Avenue in Menlyn, Pretoria,

the scheme is situated opposite the retail heart of The Menlyn Maine precinct, providing occupants of Menlyn Central with access to a range of amenities from hotels and gyms to residential units. Moreover, recent infrastructure upgrades ensure that motorists have easy access from both the Atterbury and Garsfontein off-ramps from the N1 freeway.

Looks can be deceiving

The offices will be enveloped by a seamless glass façade created under a unitised system. Strikingly, while the scheme may be just one building, there will be a clear visual distinction between the dealership and office components, giving the look of two separate entities. A critical factor in the building is its sustainable energy use. Achieved through double glazing and a central air-conditioning system coupled with a thermal energy storage system, water harvesting and energy-efficient electrical installations, the building will be energy efficient. Notably, the dealership will also utilise water recycling processes allowing up to 75% of water to be reused. Abland Grant Silverman Tel: (011) 510-9999 www.abland.co.za

Repurposing shipping containers for residential dwellings is a new trend. However, it is important to note that so-called container homes still need to comply with all building and fire-safety regulations, in addition to the architectural plans receiving council approval prior to construction. ASP Fire was recently tasked by a Cape Town architect to vet the plans for two such container homes. “The homes essentially consist of a shipping container shell, arranged on-site to form the main structure, which is repurposed as a home,” ASP Fire CEO, Michael van Niekerk explains. Several factors had to be taken into account in terms of the fire-rating approval. Firstly, Michael points out that steel in and of itself does not necessarily provide the structural stability required for a residence, as it begins to deform when exposed to temperatures over 550°C. The containers themselves were clad inside and outside for aesthetic purposes. Timber cladding was specified on one unit, which required ASP Fire to check that the distance from the adjacent structure complied with the fire-safety regulations.

“Here the option is either to treat the timber cladding so it is fire-resistant, or to specify a fire-rated fibre-cement board that resembles timber in its look and feel, as is common with American homes,” Michael concludes.

Safer work environments thanks to vacuum cleaners Many tasks on construction sites, in workshops or on the production line for industry produce large amounts of dust. Various precautions must be taken in order to comply with work protection regulations and keep the impact on health as low as possible. Even supposedly harmless types of dust can have an impact on or cause lasting damage when the concentration of dust in the air is very high. Types of dust that also contain constituents such as pollen, quartz, mould, viruses or even asbestos are especially problematic. Categorising types of dust in terms of the impact they have depends on the grain size as well as the properties and exterior shape of the material concerned. For example, what makes asbestos dust dangerous is not only its particle size, but mainly its special fibre structure. Safety vacuum cleaners like the Kärcher NT are designed in such a way that they facilitate reliable absorption and disposal of such particles. In the last few years, many aspects of safety vacuum cleaners used for vacuuming hazardous or large amounts of dust have been developed further in terms of efficiency and user-friendliness. This includes, for example, more effective

filter cleaning systems which allow uninterrupted operation, even when dealing with very large quantities of dust. New materials offer a high level of convenience. Consequently, operation, has become easier. In addition the vacuum cleaner features a built-in

power outlet, allowing it to be used in conjunction with power tools such as drills and sanders. Kärcher Anna de Haan Tel: (011) 657 7300 Email: Anna.dehaan@karcher.co.za

Fast-setting and Smooth Mapei has released its new locally produced multifunctional cementitious tile adhesive, Adesilex P4, an adhesive which can also be used as a levelling compound. Adesilex P4 is first and foremost an innovative, rapid-setting, semi-fluid, full contact adhesive which has the added benefit of 100% tile coverage, eliminating the need for back-buttering on large format tiles. This results in cost savings in both time and consumption per square metre (subject to required thickness). It is ideal for use as an adhesive on ceramic, porcelain and natural stone (non-moisture sensitive) installations in internal and external environments. The product is easily trowellable and allows for light traffic within 4 hours. As a smoothing compound, it can be used on interior and exterior surfaces generally found on site up to a maximum of 20mm thick. Provided

the substrate is clean with no loose debris, it can absorb deflections on the substrate and provides easy levelling and localised smoothing which sets within 4 hours. Adesilex P4 is suitable in heavy traffic zones, such as offices, shopping malls, hospitals and schools. Its wide temperature range means it can just as easily be used over underfloor heating installations or any other application where temperature extremes may occur.

Van Dyck Floors and Harrismith-based Nouwens Carpets will consolidate their operations in order to streamline and optimise their manufacturing and supply chains. Dr Mehran Zarrebini, CEO of PFE International, the family-owned British investment company that acquired what was then Van Dyck Carpets in 2004, said that the consolidation was still subject to Competition Board approval. However, in a challenging market where carpet manufacturers not only had to contend with rocketing input costs, an unreliable electrical supply and shrinking disposable income for home improvements but also competition from other flooring solutions, it made sense for the two companies to consolidate. Although specific details of the resulting restructuring of the two companies are not yet available, both Zarrebini and Nouwens Carpets chairman, Oscar Grobler, say that this will impact some of the 400 plus employees at the two manufacturing plants in KwaZulu-Natal.

the 5,0150-hectare Turffontein development, which consists of 525 units, 21 of which are transitional housing units. “Corobrik’s range was chosen for the outer skin of the building as it is very low maintenance. The dust and dirt of everyday living will not show up against the brickwork, retaining a clean aesthetic for longer,” explained Nico. Anca Szalavicz of ASA Architects, tasked with designing the development, concurred, saying the lack of ongoing maintenance and durability made Corobrik’s face brick the best

choice: “We used two different face bricks – Montana Light and Protea Travertine – to create some form of contrast within the design. Because of the high number of units, the design hinged on creating small, manageable, semi-private courtyards. Some of the blocks have vaulted roofs which gives the development quite a unique appearance.” Corobrik (Pty) Ltd Musa Shangase Tel: (011) 871-8600

The greenest place in Africa From 2010, when Nedbank completed its headquarters on the corner of Rivonia Road and Maude Street to become the country’s first Green Building Council South Africa (GBCSA) Green Star-certified building, Sandton Central has remained at the cutting

edge of green building practices on the African continent. Globally, evidence that the number of green buildings keeps doubling every three years proves that their advantages are too valuable to ignore.

Green architecture and materials used in the structure, services and envelope of any building contribute to its resource-efficient operations. Equally, green interiors create high-performance tenant spaces, characterised as healthy, productive places to work. They are less costly to operate and maintain and have a reduced environmental footprint. “Building green is not only the right thing to do, it enables environmental transformation and significant social gains, and also accelerates property values, reduces operational costs and unlocks higher rental. A green indoor environment gives tenants the chance to provide a more comfortable, healthier and productive space for their staff,” concludes Elaine Jack, City Improvement District (CID) Manager of Sandton Central Management District (SCMD).

Thinking outside the water-box In the world of water industry and marine applications, material choice is of extreme importance, as these are challenging environments where constant exposure to weather can really place tough demands on design materials. Aspects such as durability, weight and corrosion resistance all play an important role in such applications. According to Glen Pringle, Director of Vital Engineering, it is for this reason that the demand for their glass-fibre reinforced products has been steadily growing over the past few years, in a wide range of water-related fields. The Vitaglass range can also be used in industries where there is contact with effluent streams such as wastewater treatment works and other industrial applications. “One of the distinguishing factors of the range is that it empowers the designer to think ‘outside the box’, since the manufacturing process allows for great flexibility,” he adds. “We can tailor everything from the shape of the casting, patterns, material thickness and chemical properties to the clients’ needs, thereby giving them increased freedom.” For example, a flooring surface can vary from solid or patterned top, to mini-mesh with a fine grit top surface, where the small apertures allow for comfortable walking and prevent objects from falling through, to standard aperture meshes for maximum ventilation and quick drying properties.
