基于BIM的工程量清单编制系统构建

Construction of BIM-Based System for Compiling Bill of Quantities

工程量清单编制作为工程造价管理的基础性工作,采用传统方式进行编制,一方面存在耗时、精准度不高、易漏项等问题;另一方面对于填报的清单工程量无法追溯查询。集成BIM技术和数据库技术,借助BIM提供的数据库平台,利用Revit二次开发提取模型构件属性信息,根据清单计价规范实现工程量清单编制,同时建立工程量清单与模型构件的关联,实现清单工程量的可视化追溯查询,确保清单工程量填报的合规性,提高工程量清单编制的效率和精确性,最后通过实际工程项目验证该系统的可行性。

The preparation of bill of quantities is the basic work of project cost management.The traditional methods faces difficulties in two aspects.On the one hand,it is time-consuming with low accuracy,and easy to miss items;and on the other hand,it is impossible to trace and query the bill quantity filled in.The integration of BIM Technology and database technology is able to use the database platform provided by BIM,applying the attribute information of model components extracted from Revit secondary development to realize the visual traceability query of bill quantity.Such method ensures the compliance of bill of quantities filling and improves the efficiency and accuracy of bill of quantities preparation.At last,the feasibility of the system is also verified by the actual project.
