||The objective of this paper is to report on the development of an integrateddatabase to act as an information resource base for 4D/VR construction processsimulation and visualisation. A comprehensive database was designed,implemented and populated with the School of Health Construction Project (Aneight million pounds, three-storey development at the University of Teessidecampus). The database is composed of a core database of building componentswhich, in turn, is integrated with a CAD package (AutoCAD 2000), a projectmanagement package (MS Project) and graphical user interfaces.The core database was designed using the unified classification for the constructionindustry (Uniclass). One of the benefits of using the Uniclass method, apart fromproviding standards for structuring building information, is that it provides amedia for integrating PBS (Product Breakdown Structure) with WBS (WorkBreakdown Structure). This is an important aspect for delivering a meaningful 4Dmodel. Integrated interfaces between MS Access Database, AutoCAD Drawingsand MS Project Schedules were developed and implemented. Furthermore, theBritish Standards of layering convention (BS 1192-5) was adapted andimplemented. The database was populated automatically with detailed product datadirectly from 2D or 3D drawings, schedules of work and resources of the School ofHealth Project. This paper is also addressing object definition, structuring thedata, and establishing the relationships and dependencies within the data set, theWBS and building objects as well as modelling the building in 3D in order tocapture the essential space- and time-critical attributes of tasks. Practicalapplication of database throughout the construction process has been highlightedand discussed. A proposal for incorporating IFC model is also discussed.
