Computer-aided design (CAD) is widely used during the engineering design stage of construction projects. CAD generally contains a wealth of information regarding the facility to be constructed; this information can be effectively used for construction decision-making. This paper undertakes an investigation of the possibility of using a "product-based" model representation for integrating 3D CAD with computer simulation to facilitate better decision-making during construction. The objective is to conceptualize an environment that allows an engineer to specify how the construction of the facility is to be carried out with CAD. The environment could then extract relevant information to produce simulation models that enable better understanding of the construction process, better cost estimation and more appropriate planning.
