The AIC (Automation and Integration in Construction) Research Group at the University of Salford is currently working on the development of a PC–based integrated environment prototype called SPACE (Simultaneous Prototyping for An integrated Construction Environment). SPACE aims to incorporate various construction applications, enabling project information to be shared between these applications and allowing the user to run them simultaneously, i.e., concurrent engineering. The purpose of this paper is to present the EVALUATOR [project Estimate and interim VALUation (monthly) generATiOn in an integRated environment] application of SPACE. EVALUATOR's main objectives are twofold: (1) to produce the project estimate in the form of an elemental bill of quantities (BQ) and (2) to generate monthly interim valuation certificates from the construction plan. Various structured analysis techniques have been implemented to model this application as an integral part of SPACE. The resulting Express–G (static data) and IDEFØ (process) models are described. In addition, the sharing of information between EVALUATOR and the other relevant applications within the integrated environment is also discussed.
