基于BIM的复杂建筑造价估计模型
|
摘要
针对传统造价估计模型对复杂建筑造价估计不准确的问题,提出了基于BIM的复杂建筑造价估计模型。根据BIM建筑信息模型,对复杂建筑工程造价估计模型设定5个等级,并通过对造价评估知识域分析,将建筑工程总造价控制在批准范围之内。设立建设工程造价过程域,组建相对简单估计模型流程内部结构,采用BIM模型使结构更加直观、清晰地呈现出立体效果,并以此为基础构建估计模型。通过对比实验,得出结论,该模型对复杂建筑造价估计较为准确,为建筑造价在实际中的应用奠定了一定基础。
As the traditional cost estimation model is inaccurate in complex building cost estimation,a complex building cost estimation model based on BIM is proposed. According to the BIM building information model,five levels are set for the complex building project cost estimation model. The total cost of the building project is controlled within the approved scope by means of the knowledge domain analysis of cost evaluation. The process domain of construction project cost is set to construct the relatively-simple internal structure process of the estimation model. The adoption of BIM model makes the structure more intuitive,with the stereoscopic effect clearly presented,and on this basis,the estimation model is constructed. It is concluded from the comparison experiment that the model is accurate in complex building cost estimation,which lays a certain foundation for the actual application of building cost.
