Computer Aided Design-Based Layout Model for Site Planning

This paper presents a computer-aided design (CAD)-based site layout model designed to account for the diverse nature of construction sites. In the proposed, model, the site layout problem is represented by a flexible object-based model. The model allows the configuration of physical objects and their encapsulated attributes to suit the unique demands of each project. This feature facilitates the transfer of experts´ knowledge to a set of libraries imbedded in the developed model. The paper describes the structure of the proposed model and its four components: (i) user interface; (ii) database; (Hi) project modules. The functionality of these three components and their interconnectivity are also discussed. The developed model is implemented in a computer system that operates in CAD environment and makes use of object-based design concepts.
