Comprehensive Review on Valuation Method for Bill of Quantities in Prefabricated Shear Wall Structures Using BIM

Abstract

Prefabricated shear wall structure is widely used, it can not only meet the structural performance needs of buildings, but also greatly improve the construction efficiency of buildings. The bill of quantities valuation model has important theoretical and practical significance for optimizing the cost control of prefabricated shear wall structure and improving the efficiency of project management. From the perspective of combining theory and practice, this paper explores the bill of quantity valuation method of assembled shear wall structure under BIM environment, integrates BIM technology and SQL Sever database technology, and extracts the attribute information of model components through the secondary development of Revit with the data platform provided by BIM. The construction of bill of quantities is realized according to the specification of bill of quantities, and the association between bill of quantities and model components is established to realize the visual traceability query of bill of quantities, which provides a BIM technology-based construction engineering measurement and valuation technology and method, hoping to provide a new perspective and theoretical basis for related fields.
