基于轻量化BIM模型的铁路工程质量管理应用

Application of Railway Project Quality Management Based on Lightweight BIM Model

针对铁路工程质量管理存在的质检资料缺失、滞后、内容不规范等问题,提出以“一检合格率”指标推行分级管理,研发基于轻量化BIM模型的质检系统,借助轻量化BIM模型对铁路工程进行结构部位分解,结合质量验收标准形成质量管理最小单元,生成质量、进度、计价管理基础数据源,以检验批签认驱动轻量化BIM模型运转,把质量管理的结果延伸到进度和计价管理,并将建设单位管理关口前移,从而实现以计量计价为抓手,对工程质量进行全方位、全过程的管控。实践表明:所提出的质量管理方案有效可行,所应用的质检系统为管理者提供了可视化、智能化的质量管理手段,能为铁路行业高质量发展提供有力保障,具有推广价值。

In view of the problems such as missing,lagging and non-standard contents of quality inspection data in railway project quality management,it is proposed to take the “first-time inspection pass rate” as an indicator to carry out hierarchical management.Lightweight BIM model-based quality inspection system is developed to decompose the structural parts of railway projects,form the minimum unit of quality management in combination with quality acceptance criteria,generate basic data sources for quality,progress and valuation management,drive the operation of lightweight BIM models by endorsement of inspection lots,and extend the results of quality management to progress and valuation management.The management control point of the Employer will be moved forward,so as to realize all-round and whole-process control of project quality with measurement and valuation as the starting point.Practices show that the proposed quality management scheme is effective and feasible,and the applied quality inspection system provides managers with visualized and intelligent means of quality management,which can provide a sound assurance for the high-quality development of the railway industry and has the promotion value.
