1. BACKGROUND
All South Africans have the right to basic education. According to the Bill of Rights of the country’s Constitution, the state has an obligation, through reasonable measures, to progressively make this education available and accessible. However, if the right to education is going to be satisfied, a fundamental building block in achieving this is the provision of suitable facilities in a manner that will stimulate the culture of learning so that it can take root and grow. Impendulo Primary School is a perfect example of such a facility provided by the South African government to the community of Mamelodi in Pretoria.
The impact the project has had on the beneficiary community has been remarkable. Its success cannot be measured merely in direct benefits, such as the number of buildings erected, but rather the human benefit that the community has derived from being part of the process. The success of the project has been the direct involvement of the people in the planning, implementation and ongoing management of the facilities.

5. SITE CONDITIONS
The site is situated at corner of Gladstone Seti Street and Milenyane Tsele Street in Mamelodi East ext. 22.
Environmental Impact Assessments were undertaken to determine how any potential health risks can be rehabilitated so as to accommodate the school requirements of the learners on site. Geotechnical reports determined the type and design of footings to be used.
6. SPECIFIC REQUIREMENTS
All specific requirements have been dealt with via a process of consultation with the user client.
The specific client requirements were dealt with through a process of consultation with the relevant stakeholders of the institution.
7. POLICY AND STRATEGIC MATTERS
The project was structured to encourage participation and opportunity to previously disadvantaged individuals / contractors and Affirmable Business Enterprises, without compromising standards and skills. The project also provided skills through training and employment of the participants of The Expanded Public Works Programme (EPWP).

10. ARCHITECTURAL GREEN PRINCIPLES
Since the formal introduction of the SANS 10400 in 2008, South Africa has taken a massive step forward towards legislating the need for Green Design Principles – and this school adheres as closely to many of those principles. Budget constraints will always prevent the majority of developments from being ‘models’ of Green Design Principles but the challenge to contemporary designers remains in availing as much of these elements to the completed structure as is possible.
The school, Impendulo Primary, utilised the following principles of Green Design:
10.1. Orientation:
In the laying out of the separate Blocks a strict North orientation was adhered to as much as was possible. Not only to encourage heat absorption through the winter months, but in as much to utilise the clerestory (higher level) windows and sloped ceilings to ensure consistent adequate ambient light. Moderate eave overhangs and wide Covered Walkways prevent the spaces from overheating.
10.2. Materials and Construction:
All ceilings below roofing have a 100mm mineral wool insulation laid over them, and lapped up at wall ends. The choice of face brick was of a depth of colour that will encourage adequate heat sink.
10.3. Rain Water Harvesting and Irrigation Systems:
Where rain water does not fall onto storm water channelling, to be directed into the sub-surface storm water system, gutters at eave ends provide for the remaining water to be accumulated. For storage of this water 2 x 20000 litre tanks have been constructed adjacent to the Pump House. The harvested water is supplied to the Sports Field and Vegetable Garden via the pump system.
10.4. Landscaping
It is planned that 46 indigenous trees will be planted around the Site. Not only providing shading for the Learners, and character to the Site, the planting of trees will prevent excessive soil erosion, specifically on a Site with such extreme gradients.
10. LIGHTING
All luminaires were installed in accordance with Eskom’s energy saving policy by installing LED, Compact Fluorescent Lamps en Energy Saving luminaires which uses approximately 30% of the power of the old standard fluorescent luminaires. Perimeter night security lighting uses also energy efficient lamps.
11. LIGHT SWITCHING
Perimeter lighting is switched using day night sensors.
12. ENERGY EFFICIENCY OF HVAC UNITS
Inverter split type units were used for the site instead of conventional splits. The Inverter unit’s limits the maximum running currents required to run the units to 70% that of conventional split units. There is approximately an energy saving of 30 % as compared to your conventional units. Units were programmed such that they automatically switch off beyond working hours preventing unnecessary use of energy.
Use of Passive Building Elements:- The use of door closers on doors that lead to the outside to prevent loss of energy through open door. The use of over purlin insulation created a naturally cool building. The use of tinted glazing and overhangs to create a naturally cool building.
13. CHALLENGES
The project is set up in a community with high levels of unemployment, in this regard the contractor encountered the following challenges:
· Numerous strikes by the community. The strikes resulted in delays hence increasing the time to complete the project
· Theft of construction equipment. This also resulted in delays based on down time when the contractor had to replace construction equipment which were stolen on three occasions
· The high sloping terrain. The school is placed at the top of a mountain and therefore the amount of earthworks to be done was enormous.
· There is no proper storm water management provision from the municipality in the area. The contractor had to design a system which channels all the water from the roofs of the buildings and ensure the system works efficiently.
