A comparison between the June 1991 and Series 2000 JBCC Preliminaries editions

Abstract

The use of 'standard' or 'model' preliminaries has simplified the tendering for and the administration of building contracts, entail economic advantages to all concerned. Minimal changes have been made to the preliminaries since the publication of the first standard document in 1981. There were few editorial changes while the established principles were not revised. However, the current Preliminaries (May 1998 edition or January 2001 edition), which forms part of the JBCC Series 2000 documentation, has been completely reviewed and differs substantially from previous editions. This article attempts to highlight these differences, and to provide some background to the origin and necessity of standard preliminaries and their evolution since they came into operation in 1981.
