PREFACEDevelopment in the building industry is a continuous process. With passage of time newmaterials become available, design methods are refined and innovative building systems areintroduced. It is therefore obvious that building regulations cannot remain static if they areto allow for the early use of these developments and the eventual acceptance of satisfactorysystems as conventional building methods.The National Building Regulations differ considerably in appearance and content from previ-ous building bylaws but this does not mean that the buildings constructed in accordance withthese regulations need differ to any great extent from those built in the recent past. It is truethat the regulations have been written in their present form in order to encourage the use ofinnovative design, new materials and new construction methods where these can be shownto be suitable. However, it is equally true that any building designed in accordance with ac-cepted methods and constructed of conventional materials in accordance with the principlesof good building practice should, in general, comply with the new regulations.The National Building Regulations do not purport, and were never intended, to be a handbookon good building practice. They set out, in the simplest and shortest way possible, require-ments to ensure that buildings will be designed and built in such a way that persons may liveand work in a healthy and safe environment. There are other aspects to a building which mayaffect only the comfort or convenience of people but many of these, such as acoustic or ther-mal performance, are judged in a subjective way and are not readily amenable to control ina sensible manner by regulation. It is also obvious that the market will limit the degree to whichthese matters can be considered in the design of a building. It is important, therefore, thatentrepreneurs, designers and building owners should be aware that the mere fact that a build-ing complies with the National Building Regulations will not automatically indicate that it isa desirable building.There are many aspects to be considered and the relative economic worth of each must berelated to the final cost of the building. Professional designers are trained to take these mat-ters into account and can be expected to do sowithout any obstructive and possibly uselesscontrol by regulation. In the case where the designerof a building is not professionally quali-fied, there isa wealth of information on good building practice available in textbooks and fromorganizations such as the CSlR and the South African Bureau of Standards.As a guide to the understanding and correct interpretation of the National Building Regula-tions it is important to know the thoughts, philosophy and intent behind the regulations.Because these regulations were originally introduced as a long-term anti-inflationary measureit is obvious that they should not increase the overall cost of building. Another aim was toreduce the number of regulations to a minimum. Itwas therefore decided that as far as possi-ble, regulations be concerned only with the health and safety of persons in a building, thatall technical aspects be covered by functional regulations and that the regulations be writtenin such a way that they would assist rather than impede the use of innovative building sys-tems and designs. This should be kept in mind by any local authority when assessing a build-ing in terms of the functional regulations.In applying the National Building Regulations it will be found that in certain instances thereis an overlap with the requirements of regulations made in terms of other Acts or ProvincialOrdinances. Some of these anomalies may be overcome in the future by suitable amendmentsto other regulations but there are some regulations made in terms of local town planningschemes that it may be desirable to retain. In particular, this would refer to requirements forbuilding lines and for materials which are permitted as exterior finishing for buildings. The re-quirements in the National Building Regulations are there for technical reasons but what istechnically acceptable may not be acceptable for other reasons.

This code sets out prescriptive provisions that are deemed to satisfy the technical aspectsof the National Building Regulations and, where considered necessary, these provisions havebeen amplified by illustrations and commentary. The commentary, although not an essentialpart of the code, has been introduced in the interests of promoting better understanding ofthe National Building Regulations and the form in which they are drafted but itmust be clearlyunderstood that anything contained in the commentary has no force whatever in law.Although the deemed-to-satisfy rules are based on the work of the Technical Advisory Com-mittee that was appointed by the SABS to advise on the treatment of the comments on thefirst edition of the National Building Regulations, this code, because of its specialist nature,has not been prepared with the help of a committee as is usual SABS practice. Any opinionsexpressed herein are those of the authors and relate solely to the intent of the regulations anddeemed-to-satisfy rules or the technical contents thereof. There has been no attempt to ex-press any legal opinions as any definitive legal opinion can only be the outcome of a decidedcase in law. Any queries in regard to the contents of this codeor of the National Building Regu-lations may be addressed to the Building Science and Regulations Division of the South Afri-can Bureau of Standards.In order to ensure that the National Building Regulations will remain valid and up-to-date, boththe regulations and this code will be reviewed and any necessary revision will be publishedin September1995. It is envisaged that thereafter, revised versions of the code and, if neces-sary, the regulations will be published at 5 yearly intervals.

3. COMPLIANCE WITH REGULATIONS3.1 GENERAL. This section of the code contains rules that in each case representa way of satisfying the relevant national building regulation where such regula-tion is a functional regulation, i.e. compliance with the rule will be deemed to

satisfy the regulation. The section has therefore been divided into the same partsas the National Building Regulations and for ease of reference all the regula-tions in each part have been reproduced whether or not they have a deemed-to-satisfy rule associated with them.These regulations have been numbered in exactly the same way as they are num-bered in the copy of the Government Gazette in which the National BuildingRegulations were published. Where deemed-to-satisfy rules exist they followimmediately after the regulations to which they apply. The rules have been num-bered consecutively in each part, the number being preceded by a duplicateduse of the Part identification letter, i.e. the rules in PartK of the regulations,for example, are numbered KKI, KK2, KK3, etc.In certain cases the regulations or the deemed-to-satisfy rules have been fol-lowed by a commentary. It is important to note that this commentary does notform part of either the regulations or the deemed-to-satisfy rules and has beenincluded only for the purpose of clarifying the interpretation of the regulationsor rules or to add useful background information.NOTE. In order to distinguish clearly between regulations, deemed-to-satisfyrules and commentary, the regulations have been printed in smaller type againsta background of colour and do not occupy the full width of the page. Thedeemed-to-satisfy rules are full-page width and printed in normal type whilethe commentary is in italics and preceded in each case by the wordcommentary.
