Implementation of AEC core reference models in StartPlan

Abstract

Computer-integrated construction relies on project information being shared among various computer applications used by many project participants. This information sharing is based on models of architecture, engineering, and construction (AEC) information. While much of the development of such models is currently at a conceptual stage, many of the central concepts are sufficiently well developed for testing their implementation capabilities in a computer program using realistic examples. This paper introduces a set of AEC core reference models that combine features of many currently developed AEC information models, such as their basic representation of construction products, processes, resources, and controls. It then presents a computer program, StartPlan, that has been developed based on the AEC core reference models to test their implementation capabilities. StartPlan is a program that creates template construction plans based on the information about the project at hand using a knowledge-based system. The paper also describes construction project information that has been used as a test in StartPlan. The results from the test reveal specific advantages and disadvantages of the AEC core reference models and will be useful to the future development of AEC information models.(A)
