Research on the Preparation and Optimization of Building Construction Progress Driven by BIM Technology
At present,the conventional construction progress preparation method is mainly through the decompo-sition of construction tasks,according to different construction tasks for construction resources allocation,due to the lack of effective estimation of the construction duration,the preparation effect is not good.In this regard,the construction progress preparation and optimization method based on BIM technology are proposed.First,the infor-mation structure of the construction progress unit is constructed,and the entities in the IFC standards are used to express and identify the BIM components.The duration of construction activities is estimated with the method of quota calculation,and on this basis,the construction resources consumed by different construction progress units are calculated.Finally,the minimum of variance of construction resources input is taken as the optimization goal,and the equilibrium optimization function of construction cycle and construction resources is constructed,so as to generate the construction progress preparation and optimization scheme,and the effect of this method is tdsted.The test results show that the proposed construction plan is highly consistent with the actual construction progress,and has a good effect of construction progress.
