Technology options for the rapid deployment of clinics
This article describes the regulatory environment controlling the erection of buildings in South Africa including so- called ‘temporary’ structures; the role of Agrément South Africa with regard to certifying non-standard building technologies; the performance matrix developed by the Council for Scientific and Industrial Research (CSIR) to evaluate innovative building technologies; the selection methodology; and findings.
Recognising that historical funding models have entrenched inequity and undermined affordability of healthcare services in South Africa, the National Department of Health is introducing the National Health Insurance scheme to integrate healthcare services. This will be heralded by a renewed focus on primary health care provision and will be accompanied by an initiative to re-engineer primary health care services.1
Because
infrastructure is integral to the delivery of health care services, these organisational transformations provide an opportunity for science, engineering and technology input into the strategic planning, design, specification, equipping, and commissioning of primary healthcare facilities. In response to this challenge, (CSIR) has
embarked on a research project aimed at developing a generic clinic design using innovative building technologies that could serve as a base for future clinic design and construction. In terms of the National Building
Regulation and Building Standards Act No 103 of 1977, hereafter referred to as the Act, no person shall, without the prior approval in writing of the local authority in question, erect any building in respect of which plans
The Ikhaya Future Building System comprises of a core of expanded polystyrene (EPS) having a density of 16kg/m3
, galvanised steel mesh either side of the EPS, and finished with a 40 mm coat of 15 MPa gunite plaster.
and specifications are to be drawn and submitted in terms of paragraph 4(1) of this Act. It must be noted that ‘any building’ includes any other structure, whether of a temporary or permanent nature and irrespective of the materials used in the erection thereof, erected or used for or in connection with the accommodation or convenience of human beings; and/or the rendering of any service in terms of the Act. There are routes to compliance with the
Act (Agrèment 2010), namely: • Meeting the relevant ‘deemed-to-satisfy’ rules of the current South African National Standards (SANS) Code of Practice 10400: The Application of the National Building Regulations, when using a conventional method of construction, or;
• A valid Agrèment certificate when using a non-standardised or innovative building system, i.e., Agrement or MANTAG Certificate, where a MANTAG certificate is a distinct type of Agrèment Certificate

dealing with ‘acceptable safety and health criteria for houses and related out- buildings, non-residential schools and primary health care centres in areas where the local authority is of the opinion that the type of construction is appropriate, given that in these areas it is of paramount importance that the buildings be erected at the lowest possible cost.’2
• A rational design prepared by a competent person.
All aspects of the work that are not the subject of rational design, i.e., normally presented in relation to the structural strength and stability of a structure, must comply with the deemed-to-satisfy rules of
