While BIM technology is often associated primarily with the design and construction phases, its value extends well into the project bidding stage. Here are the key roles BIM plays during project bidding:
In China, domestic engineering projects typically use a bill of quantities pricing method for bidding. BIM technology enhances transparency by providing a clearer picture of the actual project costs and the bidding process itself, thereby significantly influencing how bids are prepared and evaluated.
With BIM, project quantity data can be extracted quickly and accurately. This enables the creation of precise quantity lists tailored to the specific characteristics of each project, substantially reducing errors such as omissions, duplications, and miscalculations. As a result, potential disputes related to quantity data are minimized before the project even begins.
Chinese regulations clearly define the timeframe for bidding and tendering. However, to shorten construction schedules, project owners often leave very limited time for bidders to prepare their submissions—without breaching legal limits. Traditionally, calculating quantities manually within such short periods is both complex and prone to inaccuracies.
BIM addresses these challenges by enabling rapid extraction of quantity data directly from the model. This allows bidders to prepare accurate quantity lists and develop effective bidding strategies swiftly, greatly enhancing their competitiveness. Currently, some provinces and cities in China have adopted online bidding processes where BIM technology plays a crucial role.
