This chapter deals with General Conditions (GC) of Contract for Building and Civil Engineering Major Works GC/Works/1 With Quantities (1998), hereinafter referred to as GC/Works 98. The structure of the new form of contract itself may be somewhat unfamiliar to those more used to dealing with the JCT family of documents. Quantity Surveyor (QS) and the Planning Supervisor, for instance, are named and perform much the same functions under both types of contract. GC/Works 98 and its predecessor document differ from JCT 98 PWQ, however, in that they make no mention of the Architect. In practice, therefore, there are unlikely to be many situations in which the Contractor would be entitled to an extension of time under GC/Works 98 but not so under JCT 98 PWQ.
