||The E-commerce, as a new trading and business mode through theInternet, has started to penetrate all industry sectors aggressively inSingapore. As value of construction procurement usually accounts for about70%-80% of the contract value, more and more portals are being set up bylocal and overseas companies to target the market, especially in buildingresources procurement, real estate marketing, etc. This research will focuson the process modelling of the E-procurement in construction, i.e. thereengineering of the E-procurement process in construction, based on thecurrent traditional procurement practice, the survey in local constructionindustry, and the survey in local construction portal providers. Theobjectives of the research are to promote IT in Singapore and to reduce theduplication of work in current construction procurement. The ideal model willbe proposed after the analysis of the above surveys and the final Eprocurementprocess modelling will be in a format of IDEF0, which is atypical diagramming method for process modelling.
