1. Determining the Bidding Control Price
Before awarding a construction contract, the tenderer must announce the bidding notice and invite qualified bidders to participate. Each bidder, meeting the required qualifications, should estimate the project costs based on the bidding conditions and submit a fair and transparent quotation. The tenderer will then select the most suitable bidder and finalize the contract.
Prior to bidding, the tenderer prepares the bidding control price, which serves as the expected price ceiling for the project. This price is either determined by the bidder or commissioned to qualified institutions and acts as a benchmark for evaluating bidding quotations. It is essential to control the bidding price carefully to keep it below the estimated investment.
When using BIM technology to enhance cost management, the tenderer relies on the BIM model provided by the designer to comprehensively extract project quantity data, reducing omissions and errors. This approach helps establish a bidding control price that aligns closely with current market prices.
2. Preparing Bidding Documents
When issuing bidding documents, the tenderer must include a list of BIM models and engineering quantities for the bidding parties. Bidders then fill in unit prices based on the tender requirements and their technical and management expertise. Because the components in the BIM model are closely linked to engineering quantities, bidders use their BIM models to verify the accuracy and reliability of the quantities listed in the bidding documents, improving the efficiency of quantity review.
Quotations are provided based on specialized disciplines, with multiple contributors completing different sections of the bidding document. Using the Luban cost software’s import engineering instructions, these various professional documents can be easily merged into a single comprehensive bidding document.
Once the bidding documents are generated, their legality and compliance can be verified, along with consistency checks against the tender documents. If discrepancies in work quantities arise, the bidding documents must be corrected to ensure compliance. The final reports can be exported via software such as Excel or Word and support printing.
By integrating BIM and network technologies, bidding management agencies can enhance supervision and guidance, increase transparency throughout the bidding process, and effectively prevent any opaque or unfair practices.
