Abstract. The tendering/bidding process is vital for companies in the construction sector. This sector includes a number of actors performing at each stage of the process three different roles (client, info provider, provider). Based on e-commerce technologies numerous systems have been developed, aiming at the electronic support of this process. A short review of those systems indicates that they mainly focus on providing information about tenders. However, they don't cover much of the bidding process, where the formation of a virtual consortium is often required and the preparation of the final bidding document requires bids from subcontractors and suppliers. SupplyPoint is an innovative European-wide research and development effort partly funded by the European Commission under the ESPRIT Programme. The SupplyPoint system will support the whole tendering and bidding process, electronically providing -in addition to what existing systems provide -services for forming virtual consortia that bid for construction projects.
