Standard System of Measuring Building Work 1999

1 Standard Systemof MeasuringBuilding Work1999 THE ASSOCIATION OFSOUTH AFRICAN QUANTITY SURVEYORSS ixth Edition (Revised) Standard SYSTEMOF MEASURINGBUILDING WORK(SIXTH EDITION)As early as the end of the previous century quantity surveyors and contractors reached consensus on the neces-sity for a Standard method of measurement for the preparation of bills of quantities for Building workThe first Standard System for the measurement of Building work in South Africa was published in 1906 by theTransvaal Society of Quantity Surveyors. Thereafter Standard systems were published at irregular intervals on anational level and the fifth edition thereof, which has been in use up to the time of this edition, appeared in 1977A comparison between the 1906 and the fifth editions reveals an enormous development and much morefragmentation from a System prescribing only how to measure the principal materials and labour to a systemprescribing the measurement of almost all material and labour in the finest detailIt is precisely this progressive tendency of development that led to the Standard System becoming tootheoretical with consequent unnecessary items in bills of quantities.

2 Furthermore the question arises as towhether it is worthwhile to spend so much time on the preparation of unnecessary comprehensive bills of quan-tities in this era of high inflation and/or high interest rates whilst many of the theoretical items in bills of quanti-ties are not scientifically priceableWith this in mind the Standard System Joint Committee began in earnest in November 1981 with the task ofproducing a sixth edition whilst they were still engaged with necessary amendments to the fifth edition. It was achallenging task especially seen in the light of the attempt to fulfil the premise of simplification on the one handand the many organisations in the industry on the other hand that had to be satisfied. The result istherefore in certain instances a compromiseThis sixth edition is the product of dedicated work over a period of ten years by an extremely capablecommittee who remained aware of their responsible task at all times.

3 It was a great honour and privilege to beassociated with such a committeeH M Sigl Chairman: Standard System Joint CommitteeOctober 1991 Standard System OF MEASURINGBUILDING WORK (SIXTH EDITION)PREFACEAs stated in the Preface above, the committee responsible for the drafting of the sixth edition faced thechallenging dual task of attempting to simplify the Standard System on the one hand and to satisfy the demandsof the Building industry on the other hand. This compromise did not satisfy everybody and the new BIFSA rep-resentatives on the Standard System Joint Committee submitted a list of items to be reconsidered. As a resultof the foregoing and coupled with other evolutionary changes, amendments to the sixth edition were issued in1996 (twice), 1998 and reprint of the sixth edition became necessary because stocks reached exhaustion.

4 The Board of theAssociation of South African Quantity Surveyors decided at their November 1998 meeting to publish a revisededition incorporating all the abovementioned amendments. It was further decided to make this documentavailable in a more economical format with the option of purchasing either an English or an Afrikaans versionMJ MaritzChairman: Standard System Joint CommitteeFebruary 1999 The Board of the Association of South African Quantity Surveyors decided in 1981 to commence with thecompilation of the sixth edition of the Standard System of Measuring Building Work and accordingly commis-sioned the Standard System Joint Committee to carry out this extensive taskAfter a fruitless attempt to reach consensus with the Building Industries Federation South Africa (BIFSA) on theuse of a unilaterally produced simplified Standard System which was to be used in conjunction with the fifth edi-tion, one of the main directives for this commission was that the compilation of the sixth edition had to focus onsimplification this time, however, with the co-operation of BIFSA through representation on the committeeThe result of the committee s work, the sixth edition, heralds a new era in the measurement of only has the instruction to simplify been adhered to but uniformity of principles has also been achieved to agreat extent.

5 Use has also been made of the so-called deeming clauses which should result in brevity ofdescriptions in bills of quantities. Meaningful merging as well as certain necessary additions were alsoincorporatedThe fact that this edition is the sixth, illustrates that the quantity surveying profession is a live one, prepared toadapt to changes. It will by no means be the last edition. There must be constant monitoring of the demands ofeach era and adaptations made accordinglyThe entire Building industry is greatly indebted to the committee for an unselfish service delivered withoutremuneration over a period of ten years. The committee responsible for the translation of the document intoAfrikaans also deserves our gratitude for its valuable contributionThe Standard System Joint Committee consisted Sigl PhD (QS) (chairman)A.
