EXPLANATORY NOTES AND NSTRUCTONS ON THE USE OF THESE
MODEL PREAMBLES
1. The document
This document is published by and is available from the Association of South African Quantity Surveyors, P.O. Box
3527, Halfway House, 1685. Telephone(011)315 4140 E-mail. administration@sags. coza
1.2 The contents of this document are intended to cover workmanship and materials encountered in a significant
majority of projects. If a material is not encountered in a significant majority of projects, its preamble will in all like
hood not be included in this document
1.3 By its very nature, this document is a"Mode document and one that is designed to act as a basis upon which to
build. It Is anticipated that it will be supplemented by a upplementary Preambles document included in the text
of the bills of quantities that will include, inter alia, the following
supplementary clauses of a general nature that practitioners may deem necessary to cover their own
individual requirements
1.3.2 additional clauses pertaining to specific materials incorporated in a project and not covered by the Model
Preamble
1.3.3 amendments to anything contained in the Model Preambles. A clause has been incorporated in the
General section of the document stipulating that anything contained in the"Supplementary Preambles
which is at variance to that which is contained in the Model Preambles, will take precedence over th
Model Preambles and apply to the works in hand
It is intended that this document will be used by reference only in the text of the bills of quantities and Will NOT b

(SANS )to describe materials and methods respectively. It is therefore incumbent on the users of these preambles
to have ready access to the relevant Specifications and Codes. Where such Specifications or Codes do not exis
suitable preambles have been compiled
2. 2 These preambles have been designed to assist in abbreviating descriptions in the text of the bills of quantities and
practitioners are encouraged to make use of this facility. e.g. The description of a stormwater catchpit would read
Brick stormwater catchpit size internally 600 x 400 x 1 200mm deep to invert fitted with and including a 450 x
300mm x 59kg cast iron grating and frame
2.3 Wherever alternatives exist in respect of materials or workmanship, specific choices have been made in these
preambles. Should users require different choices to specific items, these should be referred to in the
Supplementary Preambles as outlined in clause 1. 3
3. Additional notes in the use of these Model Preambles
3.1 Concrete, Formwork and Reinforcement
The Project Specification embodied in these preambles was compiled in collaboration with the Authors of SANS
1200G, which forms the basis for the Concrete, Formwork and Reinforcement model preambles
Users of these preambles are advised to submit a copy of the Model展开阅读全文
