SANS 0400 or be covered by a Certificate issued by the Board of Agrèment SA.


Exemption for the State The Act makes provision for the State to be exempted from the requirements of the Act under specific conditions set out in paragraph 2(3) – namely that if the building is in the interest of, or connected with, the security of the Republic or b) by virtue of economic considerations, necessity or expediency after notice in writing to the local authority in question. However, paragraph 2(4) of the Act does require that plans, specifications, and certificates as may be prescribed by the Act shall, before the commencement of such erection, be lodged with the local authority in question for its information and comment.


Deemed to comply The requirements of paragraph 7(1)(a) of the Act shall be complied with by adhering to the requirements of all the prescriptive regulations and satisfying all functional regulations by adopting building solutions that comply with the requirements of the regulations, or by reliably demonstrating, or predicting with certainty, to the satisfaction of the appropriate local authority, that an adopted building solution has an equivalent or superior performance to a solution that complies with the regulations.


Proof of adequacy of construction system Where a local authority is not satisfied as to the adequacy or safety in use of any construction system, method, material, article or product which is proposed to be used in the erection of any building the local authority may require a test report or evaluation certificate in respect thereof. An applicable report by the CSIR or any current Agrèment certificate regarding the adequacy or safety of such system, method, material, article or product shall be deemed to satisfy any relevant requirement for adequacy or safety prescribed in the regulations.


Occupancy of building classification Buildings are classified in terms of their intended use – although clinics are not directly listed in the list of classifications in the Act, ‘hospitals’ and ‘healthcare’ are listed as E2 and E4 respectively while G1 which is for offices includes consulting rooms. This becomes important when relying on an Agrèment certificate as the certificate indicates fitness-for-purpose related to the occupancy or building classification. Agrèment South Africa provides an


assurance of fitness for purpose and the quality of building innovations, for example. new building systems, components, materials, devices and techniques. It also provides sufficient technical information to enable users of the innovation as well as designers, specifiers, financial and regulating agencies to decide on the merits of the innovation

under a particular set of circumstances. Agrèment certificates provide a means of demonstrating to what extent a building innovation meets the functional and other relevant prescriptive requirements of the National Building Regulations. Currently, the criteria for the acceptability


of an innovation relate to: • Applicant’s quality system. • Acoustic performance. • Behaviour in fire. • Condensation. • Rain penetration and damp-proofing. • Structural strength and stability. • Thermal performance.


When evaluating the fitness for purpose on non-standard construction, Agrèment South Africa uses the performance approach: the requirements for a building are expressed in performance terms, and methods are devised to determine whether a building innovation complies with these performance requirements.


Accreditation of contractors It is a condition of all Agrèment certificates that only accredited contractors are entitled to manufacture, install or erect the certified construction. The certificate holder of a

current certificate is considered to be accredited. In addition, licensees appointed by the certificate holder and registered with Agrèment South Africa are considered to be accredited. The contractor shall submit proof of his accreditation together with other documentation as prescribed. An Agrèment Certificate is valid for a period of three years: a certificate holder is entitled to renew the certificate. Should the applicants fail to renew the certificate the certificate becomes inactive. Apart from tests to determine an


innovation’s performance with regard to fire resistance, wind loading, walls, foundations, roofs, and impact tests, of particular relevance to primary health care facilities are the test for heavyweight fittings (e.g., wash- hand basins), for shelving, for resistance to door slamming and for resistance to hail damage all of which can substantially affect the performance of a facility.
