|Computer based methods for facilitating building procurement have beenproposed for over twenty years, but progress on such systems has been slow.This paper describes a project built around a three dimensional computermodel of the building to be constructed, Knowledge based techniques are usedto build up the level of detail required at each stage of development. Dataentry requirements are minimised since only the information unique to theproject need be entered. Standard information is stored as default values fromprevious similar projects. The user interface is simple, with a combination ofmenus to control the flow of information and dialogues to enter textualinformation. An ‘intelligent’ CAD interface is used to enter the buildinggeometry.The system has been developed around the design and construction ofdetached houses, but the principles demonstrated are relevant across thestandard building types. In its current form the user can access the geometricand spatial parameters of the building, derive costing data and performthermal analyses. There is an option to export scheduling information to aneaernal CPM program. This furnishes the basis for planning the constructionactivities. The flexibility of the system indicates that knowledge based systemsare a viable technology for assisting construction management.
