Construction of the two dams is scheduled to take five years. The construction phase for Lupata and Boroma dams will help employ 1,488 Mozambicans. Energy minister Salvador Namburete signed the two contracts with Paulo Ratilal who acted on behalf of the two consortia.

Lupata will be build by the Hydroelectrica de Lupata; which formed by Hydroparts Holding and Cazembe Holding of Mauritius, the publicly owned Mozambican electricity company, EDM, and the Mozambican company Sonipal.The consortium involved in construction of the Boroma dam is the Boroma consortium, constituting of Rutland Holding of Mauritius, EDM, and Sonipal.

Construction of the Lupata and Boroma dams will see improvement in electricity generation in Mozambique, since Lupata dam will produce 210 megawatts and is costed at US$1.072 billions. The Boroma dam, will produce 612 megawatts on completion, and is estimated to cost US$572 million.

South Africa N4 Road rehabilitation to be carried out

Two local firms, Gulf Energy Limited and Centum Investment Company Ltd, have successfully won the bid for construction of the Lamu coal plant. The power plant is going to be constructed at a cost of US$2bn in Mombasa, Kenya. US$500m to be used in construction will be provided by equity fund, and the balance will be funded through debt. Once complete, the plant is expected to add up to 960MW of electricity to Kenya’s national grid. The move for undertaking the Lamu coal plant project is directed at reducing the country’s reliance on diesel generated electricity, which has in the past elevated the cost of electricity. This will be the largest single power generating plant in East, Central and Southern Africa, with the exception of South Africa case.

The N4 road project between Rustenburg and Tshwane will receive an additional 32km extension as plans to transform it into a dual carriage freeway continue. This will help improve on the status of the road, making it safer by decongesting the travelling between the two towns. The contract for construction of the road is priced at over US$35.80m, and will include the construction of a second carriageway with bridges and broadening of existing bridges to accommodate the new carriageway. The rehabilitation process of concrete slab roads at all toll plazas along N4 and N1 begun in June 2010, and are going on well. Some of the construction plaza projects that have been completed include Zambezi, Stormvoel, e.t.c

Self adjusting novel conveyer belt skirting system An innovator of modern bulk material handling technology has introduced a novel conveyor belt skirting system with a streamlined design engineered to fit virtually any conveyor with less maintenance and more efficiency. Martin® Self Adjusting Skirting prevents spillage and equipment breakdown caused by fugitive material by creating a constant tight seal to the belt. The unit self adjusts to rubber skirt wear, regardless of material volume and size diversity, allowing it to be an adaptable solution for an entire bulk material processing system across many different industries.

“As bulk material is processed, the conveyor belt speed, load and volume can change, which can affect the integrity of the skirting seal,” said Senior Product Specialist Dave Mueller. “One skirting system across the whole line that adjusts automatically to these diverse variations dramatically cuts man hours needed to maintain it.” As the friction from the belt wears down the seal strip of standard skirting systems, workers have to shut down the conveyor and use tools to manually adjust it. Without this type of regular maintenance, fugitive material escapes from the belt, getting into bearings and other components, which can cause expensive and unnecessary production delays.

BASF opens a new production plant in Kenya BASF Group, one of the world’s leading chemical companies has entered Kenya with a new production plant for concrete admixtures.

The new production plant for concrete admixtures was inaugurated recently. The plant, to be set in Mlolongo Kenya will seek to serve infrastructure projects that are ongoing in the country. The company manufactures cement additives and concrete admixtures among other chemical solutions for use in the construction, maintenance, repairs and renovation of structures. The plant is the company’s first for production of construction chemicals in Eastern Africa.

Headquartered in Germany, the company’s new production plant will help meet increasing demand in rail, road and airport construction.

The company has been importing the construction chemicals from Germany but now it will be easier to serve locals once construction of the new production plant is completed since it will increase the company’s efficiency in supply and lower down related costs. The time for exporting the related products from Dubai to Kenya will be reduced from a month and it will take a few days for those in need to get the products. The time taken for products to reach Kampala (8 weeks) and Dar es Salaam (6 weeks) will also be reduced following the construction of the new production plant.

SA's Infrastructure Expansion to benefit Ampcontrol Ampcontrol Africa, the local subsidiary of the international manufacturers of industry-specific equipment for the heavy industrial, power utilities, and mining sectors recently moved into their 10,000sqm facility in Boksburg, Johannesburg. Both the design and layout of the new facility were carefully thought out to enable Ampcontrol’s market leading technologies to be manufactured locally onsite, providing immediate benefits to customers. “We see robust growth in South Africa’s mining sector and this new facility will help us effectively respond to the demand in the industry as well as introduce new and even safer technologies,” said Ampcontrol Africa’s Managing Director, Edwin Bauer. With considerable investment made in both the facility and relocating Ampcontrol’s two South African-based operations into the one site, Ampcontrol is committed to the role its local operation will play in securing long term partnerships with customers across multiple markets. The new facility boasts an onsite training centre, electronics assembly area as well as transformer, power distribution and electrical system manufacturing capabilities.

Hycrete wins annual Concrete Canoe Competition

Pilosio formwork to help in building SA's motorway junction

Hycrete Inc, a leader in waterproofing and corrosion protection has won the annual Concrete Canoe Competition organized by the ASCE (American Society of Civil Engineers) with the use of its innovation in hydrophobic concrete admixtures on canoe materials. The team from the University of Nevada, Reno took home first place, utilizing a canoe made from material containing optimized concrete mix design containing Hycrete’s hydrophobic admixture.

According to Kristin Kramer, a University student and CoProject Manager for the team, “using Hycrete reduced water marks left behind on the canoe after being submerged in water.”

According to Devin Larson, UNR Mix Design Manager, Hycrete improved the workability and gave better surface finish.

The Italian company Pilosio has clinched an important contract for the supply of temporary construction site structures at the South African branch of CMC of Ravenna. The project envisages the construction of a motorway junction north of the city of Durban that includes two of the longest viaducts in the country.

The Made in Italy brand is a winner in South Africa. Pilosio, a company that manufactures scaffolding and formwork for the construction industry said the 1.5 million euros worth order to CMC involves supply of scaffolding and formwork needed, to the north of the African metropolis, to be precise, in order to provide the Ravenna Company with the equipment it requires for the construction of an important motorway junction, called the N2-M41 Mount Edgecombe Interchange.

The objective of an MNS is to protect life by indicating the existence of an emergency situation and instructing people on the actions they should take through concise, accurate, timely, and well-directed messages.

ass Notification and emergency communication was first defined in 1997 by the United States Department of Defense (DoD) in an investigative document termed: "Khobar Towers Report". The report was developed in response to the deadly terrorist bombing of an American Military housing complex in Saudi Arabia in 1996. In summary, the report concluded that significant loss of life could have been reduced and even avoided entirely if there were an effective means of alarm and "mass notification" in place at the housing facility. A mass notification system provides information and instructions about emergency conditions in a building, area site, or other space. The objective of an MNS is to protect life by indicating the existence of an emergency situation and instructing people on the actions they should take through concise, accurate, timely, and welldirected messages. This article is provided to highlight the strategic advantages of installing a governmental recognized UL2572 compliant solution.

Getting Started When developing an MNS solution, the first step is to perform a risk analysis to determine the technology that is best suited for the facility. Often, the security team provides a list of typical emergency and non-emergency incidents that they address throughout the life cycle of their campus. NFPA Standard 1620 defines a risk analysis as follows: "to characterize the likelihood, vulnerability, and magnitude of incidents associated with natural, technological, and man-made disasters and other emergencies that address scenarios of concern, their probability, and their potential consequences." The goal is to anticipate and define the circumstances under which a mass notification system shall be utilized to protect lives. Once you have done that, the next step is to establish an appropriate response for any noted incident.

Fire Alarm Emergency Voice Communication Systems Since mass notification systems provide

information and instructions about emergency conditions in real time, the live audio and text messagecontent typically drives the specific user requirements. As such, both audible and visual signal based emergency communication solutionshave been steadily growing in use over the last 40 years. The building code requires that fire alarm systems provide emergency voice communication in lieu of bells or horns in both high rise and large assembly occupancies.

With the development of mass notification, the utilization of the fire alarm emergency voice communication system for incidents other than fire has become prevalent. System integrators now look to UL-2572 compliant solutions when integrating with existing fire alarm system structures. This has come mainly from the need to provide live voice instructions to occupants in buildings, especially for large assembly and high-rise facilities where the uncontrolled evacuation of people creates more risk. Fire-alarm voice evacuation systems evolved from basic paging systems to an integrated emergency voice evacuation broadcast system that is operated from the display and control centre located at the Central Alarm and Control Facility (CACF).

Fire Alarm Systems Integrated with Mass Notification Technology In the late 1990s and especially in the early 2000s after the terrorist attacks in New York City, the industry focus shifted to providing rapidly disseminating information to mitigate casualties during emergency incidents.

Fire alarm systems are required to provide both survivability and emergency operation performance. They are afforded with emergency power and supervised circuits that report off-normal conditions on their system if they occur. Therefore, utilizing fire alarm for mass notification provides a higher level of survivability than just connecting to a disparate computer or VOIP based telephone system.

In the late 1990s and especially in the early 2000s after the terrorist attacks in New October 2014

York City, the industry focus shifted to providing rapidly disseminating information to mitigate casualties during emergency incidents. Fire alarm systems are required to provide both survivability and emergency operation performance. They are afforded with emergency power and supervised circuits that report off-normal conditions on their system if they occur. Therefore, utilizing fire alarm for mass notification provides a higher level of survivability than just connecting to a disparate computer or VOIP based telephone system. Fire alarm systems are regulated to provide both signal audibility as well as emergency message intelligibility. This means that when integrating security and IT messaging systems, fire alarm systems provide a higher level of performance.

There are many factors that affect the intelligibility in voice messaging design, including: • Reverberation generated by the various surface materials and furnishings of a facility; • Speaker properties such as sensitivity, power output, and coverage; • The speaker layout in a facility based on room dimensions and surfaces Mass Notification/Fire Alarm Integration Advantages Since fire alarm systems must be supervised and wiring faults must be reported, the user confidence in the system performance is ensured. This is especially important when utilizing a fire alarm system for mass notification incident broadcasting. The emergency response team will be confident that the system will operate as intended during the incident.

Fire alarm systems are combined with various peripherals such as sensors and speakers which are considered "safe" units. In a "safe unit", regulatory testing is performed to ensure that unit construction will withstand the test of time and internal wiring of the unit does not have to be supervised. Safe units are verified with their control equipment through compatibility testing during the manufacturer listing phase, and regularly on-site via system tests and inspections performed at specified intervals. For example, the National Fire Code of Canada requires monthly operational tests of the fire alarm emergency voice communication systems.

Fire alarm systems undergo the most comprehensive laboratory testing to ensure survivability. Examples are as follows: • Environmental dynamics: high temperature, low temperature, and high humidity; • Power supply lines transients such as varying nominal, under, and overvoltage inputs to the system; • Enclosures performance tests such as quality construction and resistance to electromagnetic interference; October 2014

•

Emergency backup battery tests such as the charging circuitry is evaluated for its potential to provide 24 plus hours of battery backup for both lightly and fully loaded system configurations.

Fire alarm systems and their real-time operating systems and dedicated firmware also provide sophisticated scheduling options and advanced logic constructs to allow customizable programmability as required. Software is guaranteed to perform in a consistent manner without fault and with predictable timing. The software written for fire alarm control units often follows standards adopted in other life-safety critical environments including avionics, health-care, and nuclear facilities. For the reasons mentioned above, mainly the remarkable reliability of all hardware, supervision of all external wiring, well designed real-time embedded software routines, and system design and programming flexibility, fire alarm systems have become the de-facto platforms for Mass Notification Solutions.

Mass Notification Market Potential According to recent market research, the global market for Mass Notification Systems is predicted to be $2.41 billion by the end of 2013 to an estimated $6.41 billion in 2018.

What's Next in Emergency Communication Systems?

• Development of smart messaging algorithms based on phonomies and human behaviour during emergency situations; • Revisions to the Canadian Common Alerting Protocol (C-CAP) as an industry standard for MNS reporting; • Adoption of the new CAN/ULC-576 mass notification equipment standard by the local authorities; • Integration of Building Information Modeling and Geospacial Information Systems as applied to emergency response visualization tools; • Increase in the use of wireless tactical emergency graphical display systems.

Modern formwork systems Saving time and money

U

se of formwork and scaffolding in construction of concrete structures is a major contributor to the overall cost of construction. One research study suggests that this cost can run up to or over 40 percent of total construction project cost. In addition, use of formwork affects speed, quality and safety in construction of walls, floor slabs, columns, beams, stairs, window hoods, and balconies, as well as other structures.

With increased activity in the construction sector around Africa, a prudent contractor needs to complete jobs quickly and increase his margins, in order to enhance competitiveness and increase profit margins. Enhanced delivery time has also become an expectation by many governments and private developers since these facilities are needed as quickly as possible, in order to supply services to a burgeoning population. There has also been a great interest, among users, for buildings that achieve certain quality standards and specifications such as green star – ratings. Achieving high quality also calls for use of high quality construction materials in the building process and formwork and scaffolding systems are one of the essential ingredients.

Use of traditional formwork by contractors cannot be trusted to deliver the expectations of the ever expanding construction industry in Africa, as well as fulfill the need for investors, contractors and governments to improve delivery time on infrastructure and construction projects.

October 2014

The old way Taking a walk down memory lane reveals that timber formwork and scaffolding was the first to be used in the construction industry in the form of timber columns. The category includes those made of bamboo. Advancement of technology then led to some improvement, where ply woods, supported by steel pipes, were used.

Smaller formworks that would be connected together in construction works were then invented. Larger formwork followed and were used for construction of slabs, beams and columns among other structures.

These consisted of previously invented smaller formwork systems, linked together. The material used for larger formwork systems was steel and they became too heavy, leading to a shift to aluminum, plastic and fiber glass, among other materials. Traditional formwork systems are associated with and much loved for their low initial cost, need for low expertise, user experience, and low weight, but they are condemned by their poor finishes on concrete walls and columns/slabs, spending of a lot of time when using them in construction, their high labor requirement, and their need for high skilled labor.

Indeed, 50 percent of labor can be spent on filling in irregular openings around columns, corners and other penetrations in traditional formwork systems.

Prefabricated formwork systems Evolution of system formworks has seen entry of prefabricated formwork for slab panels, slab decks, beams and

columns. For instance Doka formwork presents a category of formwork systems that are semi system in nature, These comprise of steel parts and plywoodbeing used for ensuring smooth concrete surface in construction of slab decks, beams and columns . Doca is a Canadian company supplying semipermanent formwork solutions around the world. However, pre-fabricated formworks are used for slab panels and supports. Modern formwork systems represent fabricated modular components with casting panels. The formwork is prefabricated before transportation to the site, according to the work needed – particularly, the shape needed. Modern prefabricated formwork is the most economical when it comes to high-rise buildings, medium construction and large construction works.

Cost Reduction Since formwork systems contribute to a large extent to construction costs, cost reduction can thus be achieved by using steel/aluminum prefabricated formwork systems that reduce the massive labor costs spent when setting up and putting traditional formwork systems in place. Labor costs also reduce when lighter models of aluminum/plastic or innovative steel formworks made of lighter steel components are used, since many of these systems can be handled and put in place or carried from floor to floor by one person.

Massive transportation costs saving can be achieved by use of lighter aluminum formwork systems such as from MFE Formwork Technology, a Malaysia-based global company that manufactures lightweight aluminum formwork systems.

Innovative slotting-in ribbed formwork systems allow low weight overall, hence becoming preferable in cutting down transport costs and labor costs required in moving them to, from and around the work site and putting them into place.

This is according to Mr Henri Pereira from Roofix Africa who notes that massive labor costs can be achieved by use of Roofix systems that can be carried around by one person, from one floor to another. Roofix Africa is based in South Africa and manufactures permanent slotting-in ribbed formwork systems for concrete works.

Moulded and extruded plastic formwork systems are also a trend in ensuring that contractors do not incur large construction costs, since they are lighter to carry and handle around. “Minimal propping requirements due to the lightweight nature of the slab system also becomes a strategy of reducing construction costs when proper formwork systems are selected”, according to Kenndy Jimba from Voidcon. Voidcon is a South Africa-based company supplying permanent and temporary formwork and decking systems. Experts do not differ with regard to use of innovative formwork systems in cutting down construction costs. Bridgend’s Ally Mumtaz agrees that contractors who 16

October 2014

utilize innovative uPVC plastic shuttering systems cut down on labor costs and that “most contractors report back in excess of 30% (construction) cost savings.”

Saving of time and ease of assembly Construction cost is also reduced when formwork leads to quicker construction, such that the project is not affected by issues of material price change over time, and when such quick completion helps the contractor to move to another project promptly. In addition saving of construction material costs is realized with perfectly prefabricated modules since no concrete is needed to fill in non-perfect joints and corners in structures being built. Time overruns affect many construction projects, with research revealing 50-80% over-runs. In Africa these figures are probably much higher. With construction projects come completion timelines, which if not adhered to lead to increased costs of labor and material due to price changes over time, as well as underlying repercussions on society related to political factors when governments change. Contractors also need to finish jobs quickly to undertake more and untie construction resources to optimize profits. Mumtaz agrees with the observation that careful selection of formwork systems can help such contractors working on a “stringent timeline constraints.”

The need to reduce time overruns on construction and the need to reduce time for construction phases, has led to studying of the impact of use of recent technologies on the same. Research has since found that the presence or absence of precast facades does affect the time of setting up the superstructure in a high-rise building, in addition to several other factors. According to Mcnutt, the Regional BD Manager at MFE Technology Formwork, systems that are cast monolithically in a single site-based operation, allow contractors to achieve unprecedented speed of construction. Designs of various sections of many types of structures are largely repetitive, and thus, use of precast module formwork systems made of similar standard units has been found to be effective in cutting down the construction time.

One system formwork unit is simply applied in another section during construction, and thus the contractor only needs a few non-repeating formwork units – thus providing savings in terms of time and money.

Prefabrication of formwork units allows designers and contractors to become familiar with standard units and thus can help reduce the time spent in deciding the sizes needed in future projects. Precast formwork comes with lesser joint areas and units that need to be reorganized, reassembled and screwed together, thus cutting down on time for assembling and disassembling the formwork October 2014

systems. Such formwork systems help eliminate need for projects to take more time, which translates to additional labor costs. For instance, Roofix systems that have no joints to be screwed together, according to Pereira, “will speed up building of concrete walls and concrete floors, thus saving on overall construction costs”.

Reuse Indeed, using temporary steel, plastic or aluminum can increase the number of re-use of formwork systems,meaning that a company does not need to buy another set of formwork system materials when undertaking another project in another place: they will simply disassemble the units and transport them to the second site and reassemble them ready for re-use. The number of reuse runs even over 300 as notes Richard Mcnutt from MFE. Remember, timber formwork can only be reused a few times before the timber begins to bend, break or is affected by water and chemicals.

Thus, using timber formwork can increase the overall cost for a contractor who is undertaking many projects over time, compared to use of a steel formwork system.

Reuse does not only apply in regard to reapplication of the system in subsequent construction work, but also involves the ability possessed by plastic formworks such as from Moladi, to be moulded into other products other than becoming wasted after breakage, thus allowing for 100% recyclability. Moladi is a South African company manufacturing injection moulded plastic shutter formwork system that can be reused up to 50 times.

Smoother finishes - high quality job Pre-engineered formwork systems are manufactured under controlled environment and thus, achieve high quality work and can be trusted to deliver the high quality aspects needed in sensitive infrastructural projects and buildings – these are important for meeting specific building standards in many African countries.

Safety and strength of structures The issue of construction worker safety is also increasingly becoming of great concern among contractors, governments, entities and investors in large.

Thus, it is also important that solutions “guarantee the highest possible safety standards,” According to Luca Drigani from Pilosio. Pilosio is an Italian formwork and scaffolding company with branches in South Africa. Not only do projects get derailed by weather changes, but also that structures and buildings actually are brought down or destroyed by earthquakes, massive rainfalls, powerful winds/cyclones, and poor quality construction materials, among others.

Tie-off bars on prefabricated steel formwork can be trusted to deliver worker safety and strong structures compared to wooden supports that are prone to tremors/ earthquakes or wind interruptions. Permanent formwork systems also add strength and stability to structures when left in place after the pouring of concrete.

scaffolds, access scaffolds, birdcage scaffold, shoring tower and façade scaffold. The newest release from Peri, the Peri UP system falls under this category. Pereira agrees with the fact that future systems will allow designers to think out of the box and use it to create truly beautiful structures.

Permanent formwork systems are also being used to a larger extent, to allow builders save on construction time and labor costs, since labor would be required to remove them from place. According to Richard Mcnutt from MFE, their light aluminum systems are cast monolithically in a single site-based operation, allowing contractors to achieve unprecedented speed of construction. It is likely that most formwork systems in future will incline towards offering capacity for contractors and workers to do quick changes at the job site, during implementation of various tasks, according to David Espadas from Alsina, a Spain-based company providing formwork solutions. Presently it is not unusual to find concrete structures using wooden poles Innovative formwork systems and trends in the market The most dominant innovative category include the lightweight aluminum/steel-based slotting-in ribbed formwork structures that are light in weight, can be put in place by one person, can be used where there are no cranes, and which are used for setting up all types of structures. Modern innovative formwork systems that do not allow for displacement of concrete volumes by voids can help increase concrete savings. Voidcon’s permanent formwork can manage savings on concrete of up to 60% according to Jimba, the Marketing Director at Voidcon.

Innovative slotting-in ribbed formwork structures do not require much reinforcement and thus cut down on labor costs. Molded plastic formwork modules join aluminum systems that are helping reduce the much handling needed with heavy and bulky steel systems.

Technology advancement is also helping in manufacture of unit-based formwork systems, where one unit can be applied in building many sections of the structure – thus eliminating the need to buy extra units. Just last year, peri introduced the new PEP Ergo Slab Prop that, according to Voss Sylvia from the company, comes “with a reduced weight of the prop, therefore offering a costeffective solution for slab support.” Another trend is use of new systems that can manage various construction jobs, including those applicable as stair towers, suspended October 2014

lashed together with ropes as scaffolding while wooden planks have to be nailed into place by carpenters before pouring wet concrete to form a slab. This process is slow, tedious and wasteful. If Africa is to move forward in the development of its construction industry there will need to be a definite shift towards the use of fabricated formwork systems in order to save on costs, dwindling forest cover and improvement of safety.

Pilosio SpA Pilosio, a company that manufactures scaffolding and formwork for the construction industry has announced it has won an order worth around 1.5 million euros with the Italian construction company CMC of Ravenna which has operated for a long time in South Africa and has branches in Johannesburg, Cape Town and Durban.

Since 1961, Pilosio has represented Italian excellence in the production, sale and rental of building structure, like scaffolding, formworks for walls and slabs, trench lining for safety in excavation works, as well as structures for entertainment events, such as stages, grandstands and covered areas.

In detail, Pilosio’s structures, 70% of which will be tailor-made specifically for this site will be used for the construction of two imposing viaducts created with the

“casting” system to avoid any interference with the traffic below. The dimensions will be 26 metres high by 947 metres long, and 18 metres by 443. Pilosio will supply 200 sqm of P300 formwork for foundations and trusses, 500 sqm of special steel formwork divided into five sets for the construction of the viaducts’ pile shafts, an additional 350 sqm of special steel formwork made up of three sets for the construction of the pier caps, two sets of Maximix formwork and custom-made products for a total of 940 sqm, as well as the Omnimode shoring system with customized solutions for the creation of the suspended work platforms to be used in the installation phase of the roadway ashlars.

The special technical solutions and the onsite assistance guaranteed by Pilosio were decisive in winning the order.

In fact, Pilosio’s technical office provided a swift and high qualified response to the various critical areas of the construction site, the co-ordination with the various organisations involved in the project and the design of a special formwork system for the piles that could be adapted to two different sizes and for the roadways of the viaducts, optimised for the use of installation technology with buttresses. Pilosio gives added value in its services by providing assistance for customers, both in Italy and around the world, offering a wide range of products that maintain high standards of safety and quality.

Fire prevention in building

By Erick Mong'are

O

ver the past few decades fire protection and prevention have undergone an evolution.

Unprecedented new hazards and threats

have emerged. Fires are burning differently because of modern construction techniques and furnishings; budget constraints are limiting staffing, equipment purchasing, training and firefighters now face not only new hazardous

materials and technical rescue challenges but also terrorist and criminal events. Africa has the highest fire losses in terms of frequency and total losses and therefore new facilities and renovation projects need to be designed to incorporate efficient, cost-effective passive and automatic fire protection systems.

Fire Systems Traditionally fire systems provided early detection in order to warn occupants, initiate evacuation and notify the proper authorities. Although this is still true, as a result of recent terrorist incidents, school shootings, and natural disasters, the role of a building’s fire systems has expanded. These systems have evolved into emergency communication systems that provide essential information that is needed for occupants to respond during all types of emergencies. These systems should be effective in detecting, containing and controlling or extinguishing a fire event in the early stages. Fire protection engineers must be involved in all aspects of the design in order to ensure a reasonable degree of protection of human life from fire and the products of combustion as well as to reduce the potential loss from fire.

According to USA-based Firetrace International’s marketing director Scott Starr involved parties should appreciate the importance of providing mission critical fire equipment system with dedicated proven fire protection and appreciate the impact on the company that a fire can have if a piece of mission critical equipment is destroyed.

October 2014

For these systems to be effective in providing information, it is imperative that building occupants can hear and clearly understand the messages. In the past, a lot of attention was focused on audibility.

Signage for evacuation Everlux’s photoluminescent safety signs and complete photoluminescent Safety Way Guidance Systems. Other than audibility, another aspect that enhances safety is visibility especially in the event that the buildings interior is plunged into darkness. When installing such signs, end users should be familiar with the luminance properties of the photoluminescent safety signs they are planning to purchase and install in their buildings.

The luminance intensity and period of light decay are determinant on how effective a safety sign will be during an emergency situation. There are many International Standards that set the minimum luminance performance on safety signs, namely ISO 16069. To ensure they are getting photoluminescent safety signs with a reliable quality, end users should require photoluminescent safety signs from recognized and certified manufacturers. They should require that the signs have their luminance properties printed on as well as the name/ brand of the manufacturer and that they are given a copy of the manufacturer third party certificate.

Everlux limited is recognized within the fire protection industry as a leading supplier of photoluminescent safety signs’s sales manager Tiago Pedrosa adds that it has been proven that in the event of fire and the consequent accumulation of smoke only a low location lighting system, safety signage systems at floor level will be effective in providing continuous guidance to evacuees throughout the evacuation routes. Therefore, the requirements for low location lighting systems are increasingly becoming integrated in many international building.

A few minutes can mean the difference between only minor damage and a situation that is way out of control. The faster everyone gets out of a house, and the firefighters can get to the scene, the better the chances are that the repairs needed will be minimal. Their should be smoke detectors and a fire alarm installed in buildings to offer 24 hours a day, 7 days a monitoring service. If a problem arises, day or night, the service notifies the fire department immediately to minimize any damage.

It is also important that customers buy the appropriate gadget in order to effectively prevent occurrences of fire.

According to Cesar Covarrubias from Brooks Equipment, October 2014

clients should learn as much as they can about fire safety and the various fire codes. Having basic knowledge will help one understand which products they need for which applications ensuring that they are getting the right equipment. It’s also important for people to look for gadgets that can detect gas once there is a leak it can be controlled before a fire starts. In this issue we will be addressing some of the specific issues associated with providing operational fire protection systems in buildings.

FoamFatale Greece Ltd FoamFatale Greece Ltd. is a fire and safety company that specialised in oil storage tanks, terminals, refineries and power plants. Their company designs, manufactures and supplies the breakthrough Self-Expanding Foam System (SEFS).

By Dan Nsalasata he Village Mall Bugolobi is the newest addition to the predominantly residential neighbourhood of Bugolobi. This upmarket shopping mall will not only cater for the needs of shoppers within its primary catchment area of Bugolobi, but also those from Mbuya, Kitintale, Mutungo and Luzira. The Mall is a welcomed development by the heavily-populated Bugolobi community that now has several office developments within its environs. The shopping centre has three floors and has a unique and vibrant tenant mix with diverse offerings that will leave shoppers spoilt for choice.

T 30

Outlets to choose from The Mall has attracted interest from strong brands like Nakumatt, Barclays Bank and Orange Telecom, among others, while also drawing the attention of internationallyacclaimed brands like Kentucky Fried Chicken (KFC) and Nairobi Java House - all occupying the ground floor. The USA based restaurant chain- KFC is the world’s second largest restaurant chain (as measured by sales) after McDonald’s with over 18,000 outlets in 120 countries and territories as by December 2012.

Others are Brood Confectionery, C&A Pharmacy, Banana Boat, Elite Computers, Laville Wines, Spotclean October 2014

Uganda Drycleaners, Kings Gadgets, and MTN among others.

Accessibility to the first floor can be made using the stairs, ramp or the state of the art panoramic lift that offers a splendid view of the mall and the courtyard below. On the first floor, you will be welcomed by the food court which comprises 5 outlets with various cuisines; Chinese, Italian, Indian, and Ugandan. It even boasts an ice cream parlour.

The food court design, low ceiling and lighting, creates a warm and cosy ambience thus setting the mood for a relaxed dining. Right next to the food court are a bookshop and high-end wine lounge while the kids play area is strategically placed adjacent to the food court. Other stores on the first floor include Kids World, Millennium Infosys, Era Beauty lounge & salon, Design me Interiors (Interior decor), Dazzle (ladies’ boutique), MTN (service centre), Liquid silk (Sports bar), The Groom (men’s apparel) and eye care centre.

The second floor offers fine dining restaurants to cater for family and private dining, a gym, spa, men’s only exclusive saloon (men’s refinery) and the mall’s management office. Accessibility to the centre has been made even easier with the creation of five entry/exit points; two on spring road (Old Port bell road), one on Luthuli Avenue, another on Bandali Rise and a service entry/exit point at Bandali Close.

Pinnacle Homes Kitengela A huge beginning for NAI-TEX Developers

K

itengela, a bustling town located 30 kilometres south of Nairobi, is the new home to Kenya’s fast growing middle class. Every day, maisonettes, bungalows and apartments are coming up in the area.

There has been a huge influx into the town by families previously living in rented premises in the capital. Many have put up their own homes while others have purchased ready properties. Realizing the town’s potential, investors have also flocked the area in droves. Almost all the banks, hospitals and major insurance firms have branches in Kitengela town. Manufacturers have also set up outlets in the town. Like in other areas surrounding Nairobi, developers have identified an opportunity in Kitengela as more people seek to move away from stifling congestion in the capital city. Among the big property investors in the town is NAI-TEX Developers Limited, who are putting up 107 homes under the brand Pinnacle Homes.

designed housing development with homes built to high standards and featuring superior finishes. We also intend to incorporate as much greenery, trees, shrubs and grass”, they say. The project’s concept is to develop single-family housing within a master planned gated community.

The development will occupy an 11-acre parcel of land and will consist of four-bedroom, two-storey single-family houses. The homes are targeted for sale to the middle household income segments in and around Nairobi and Athi River areas. The development will also include a 3,000 square foot commercial centre, an on-site

Project Scope According to the developer, the overarching concept is to build quality middle income homes in a serene, well maintained environment that offers adequate living spaces with plenty of outdoor space such as parks and children play areas where inhabitants of the community can meet and enjoy. “We are delivering a well thought out and October 2014

bio-digester sewer system, water borehole, and several communal pocket parks. It will also feature well lit streets and similarly lit parks and common spaces. The homes will be constructed using EPS panel technology in lieu of conventional stone masonry units. Each home will sit on a plot size of approximately 3,500 sq feet which will be separated by â&#x20AC;&#x153;knee-heightâ&#x20AC;? hedges. There are two distinct home designs both consisting of 4 bedrooms, two and half baths with spacious well lit rooms.

Project Team Client: NAI-TEX Developers Limited

The homes are open style designed with the intended purpose of bringing in plenty of natural light. High quality paint and stylish tile floor finishes will be used in all areas.

There will be an option to install wood tile floor finishes in selected living spaces. Residents will have excellent views of Ngong and Lukenya Hills.

Three Decades of Gitutho Architects & Planners A dynamic and refreshed family practice firmly focused on the future

nitially Gitutho Associates consulting architects, the firm was registered in 1983 by its principal architect, Kamau Njendu. Arch Kamau Njendu has been a private practicing architect since 1982. He studied at the University of Nairobi where he obtained both his bachelor and masterâ&#x20AC;&#x2122;s degrees in architecture. He briefly worked at the Ministry of Public Works in various positions, eventually working with Municipal Council of Mombasa and becoming the first African Chief Architect of the City of Mombasa. It was in 1982 that Arch Njendu decided to go into private practice. Since then, the architect has built a career synonymous with excellence and reliability.

He is not only a well known architect in the fraternity of architects but is also a respected man in the Mombasa and October 2014

He is a fellow member of the Kenya Institute of Management and a life member of Child Welfare Society. A husband, a father and grandfather, he has consistently shown grace and respect when dealing with clients, professional colleagues and his staff.

of Arch Njendu until 2010 when the consultancy was rebranded to become Gitutho Architects and Planners Ltd. The move also saw the entry of Arch Njendu’s daughter, Arch Mugure Njendu, who became a partner.

When Arch Mugure is asked about working in a family consultancy with her father, she has nothing but praise for her mentors’ guidance and stoic career. Unlike many family practices, the two work well together in a partnership framed with respect and confidence in each other's strengths.

The amiable architect, who made it to the list of Top 40 Women under 40 during a survey conducted by the Business Daily newspaper in 2014, graduated with a master’s degree in Architecture in Suburb and Town Planning. Naturally, it meant that the rebranded firm would now have expanded capacity to undertake urban and master planning in addition to regular architectural work. Arch. Mugure is also a qualified Arbitrator.

As a partner in the firm, Mugure has been involved in various projects and business development, expanding the firm’s geographical scope to cover other parts of East Africa. A firm believer of East African cooperation, Arch Mugure currently serves as the chair of the Ethics and Practice Board at the East African Institute of Architects.

However, the head of the practice, Mr Predrag Rajnovic (Pedja), is an experienced professional with nearly two decades in architecture. The firm is registered with the Board of Registration of Architects and Quantity Surveyors (BORAQS) and Architectural Association of Kenya (AAK). It is also a member of the Royal Institute of British Architects (RIBA). Block 45 currently has a staff of six consisting of three architects, one interior designer, two technicians and one administration assistant.

In future, the firm intends to expand to a partnership to depart from the current structure of sole proprietorship.

The firm is guided by the desire to give value for money.

Services Offered Block 45 offers architectural, interior design and project management services. Most of its projects have been in the high-end residential market. However, it is now branching out into other sectors such as commercial and educational buildings. The director also has a wealth of experience in hotel design which would come in handy when contracted to provide services in the hospitality sector.

Industry Perspectives According to Mr Rajnovic, who holds a Bachelors Degree in Architecture among other qualifications, Nairobi is a sophisticated market where the client’s expectations often exceed the level of service they get. He feels that an improvement is needed in construction technology and access to locally manufactured products. “At the moment, the construction industry is heavily dependent

upon imported goods, which makes procurement more complicated and building costs higher”, he says.

On professionalism and regulation of the construction industry in Kenya as a whole, Mr Rajnovic observes that although there are adequate regulations covering consultants, “on site we find that there is a shortage of qualified and skilled individuals.” He decries inefficiency in the building process which is normally reflected in the construction cost. Ultimately, he says, it is the developer who suffers.
