Abstract: Method of topologically subdividing and unambiguously defining the scope of work and for inter-linking construction plans/specifications to construction contracts to eliminates errors and uncertainty in contractor performance. Electronic overlays are applied onto the digitized construction plans corresponding to different categories of work. Each overlay is divided into a series of optimized topological subdivision boxes which uniquely identify/locate on the plans work to be performed. Overlays and boxes are linked to the subcontracts so the scope of work to be bid is accurately mapped to corresponding regions and overlay category on the architectural drawings. The Internet-based method provides bi-directional flow of information from various entities involved in the bid process permitting more efficient and effective management of bidding.
