Implementation Guidelines for the Bid Evaluation Methods of Bidding and Tendering Applying BIM Technology in the Construction of Housing Buildings and Municipal Infrastructure Projects in Anhui Province (2025 Edition)
Chapter One General Provisions
1.1 In accordance with the Anhui Provincial Department of Housing and Urban-Rural Development and eight other departments' Implementation Opinions on Promoting the Application of Building Information Modeling Technology (Jian Biao Gui [2024] No. 4) and its relevant provisions, and in order to encourage tendering with BIM models, explore BIM-based bid evaluation, and improve the Anhui Province housing building and municipal infrastructure construction projects' application of Building Information Modeling (BIM) technology in the bidding, tendering, and bid-evaluation mechanism. These Guidelines are hereby formulated.
1.2 The Anhui Province Model Tender Documents for Construction of Housing Buildings and Municipal Infrastructure Projects (2025 Edition) provides four bid evaluation methods—the “Evaluated Lowest Bid Price Method,” the “Reasonable Low Price Method,” the “Comprehensive Evaluation Method,” and the “Qualitative and Quantitative Evaluation Method”—for the tenderer to choose from. For projects applying BIM technology, the specific scope of application, the evaluation criteria, scores, and weights of each evaluation factor shall refer to Chapter Four, “Bid Evaluation,” of these Guidelines.
1.3 The construction project BIM electronic bidding and tendering system software used at the bidding and tendering transaction venues shall comply with the following provisions:
1.3.1 The Electronic Bidding and Tendering Measures, the Technical Specifications for Electronic Bidding and Tendering Systems, the Testing and Certification Specifications for Electronic Bidding and Tendering Systems, the Data Specifications for the Anhui Provincial Public Resources Trading Platform System, and other relevant national and provincial provisions and technical standards and specifications requirements;
