Quality Evaluation Method of Lightweight Site Model Suitable for BIM Forward Design

为突破目前将场地模型便捷地应用到BIM正向设计的瓶颈,提出了轻量化场地模型生产及模型质量评价方法。该方法首先分析了场地模型数据架构,利用LOD原理实现场地模型轻量化处理;然后,基于现有场地模型质检规范,提出了改进质量评价因子及其权重和阈值区间,利用质量分数检验产品质量;最后通过实际工程进行了验证。

In order to break through the current bottleneck of conveniently applying the site model to BIM forward design,a method for lightweight site model production and model quality evaluation is proposed.First,the data framework of the site model is analyzed,and the LOD principle is used to realize the lightweight processing of the site model.Then,based on the existing quality inspection specifications of site model,it is proposed to improve the quality evaluation factors and the interval of the weight and threshold of these factors.And the quality score is used to inspect the product quality.Finally,the verification is carried out by the actual projects.
