    Abstract

    The AIC (Automation and Integration in Construction) Research Group at the University of Salford has developed a PC based integrated environment prototype-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 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 two fold; (i) to produce the project estimate in the form of an elemental Bill of Quantities (BQ), and (ii) to generate monthly interim valuation certificates from the construction plan. Previous work has adopted various structured analysis techniques to model this application as an integral part of the other applications in SPACE. The implementation of the resulting Express-G (static data) and IDEFO (process) models into SPACE, leading to the development of EVALUATOR's estimating and monthly interim valuation modules are described.
