52 52 TECHNICAL TECHNICAL Amongst all the laws – which one should I comply with? By Patrick Gordon Before 1977 there were no common national building regulations in this country. Since 1977 we have had the National Building Regulations and in 1990 revision was published, and the different parts have been revised as recently as 2011. The building regulations are very much the law by which we must abide when doing any designs and building work. The regional municipal bylaws cannot take away any of these laws, but can, and often do, add to the minimum requirements set out by the NBR (National Building Regulations). The law does allow for a rational design when we are faced with design obstacles. These rational designs may not detract from safety: Extract from SANS 10400 – RESPONSIBILITY FOR DESIGN AND CONSTRUCTION Any rational design of a structural system shall be done or checked by a professional engineer or other approved competent person, and such person shall certify that such design complies with the requirements contained in regulation B1: Provided that nothing shall be construed as precluding the use of rule HH1, JJ1, KK1, LL1, or NN1, as the case may be, where the use of such rule is appropriate. The NBR also points to the other SANS regulations pertaining to the specifics of the installations. An example of this is SANS 10254 for geyser installations and repairs. The City of Cape Town for instance has in their Bylaws made rules pertaining to water conservation much stricter than the NBR. So, you will be expected to comply fully with the National Water Regulators and the Municipal Bylaws when you do any installation in the Western Cape. The inputs of a panel need to be considered when listening to the requirements of a customer, but the result may not be in contravention of the regulations. www.plumbingafrica.co.za @plumbingonline @plumbingonline @PlumbingAfricaOnline April 2020 Volume 26 I Number 02
