Research On Construction Site Layout Based On BIM

Construction site layout is the premise and foundation of construction activities,and plays a vital role in the smooth progress of construction activities.However,in reality,the construction site is often laid out by project managers based on engineering experience and personal preferences.Such an arrangement lacks an in-depth and detailed understanding of the entire construction activities,and lacks scientific theoretical support.It is difficult to meet the needs of construction activities,which will bring about a series of problems such as increased construction costs and delayed progress.Therefore,we need to establish a scientific and reasonable layout method for the construction site layout based on a thorough understanding of the construction activities.This article first determines the maximum consumption level of various materials required for construction through the 3D building model and construction schedule of the proposed building,and then determines the type and size of temporary facilities to be arranged from the maximum consumption level of various materials.Secondly,the system layout design theory in the plant equipment layout is introduced as the basis for the construction site layout.The objective is to establish the objective function based on the minimum logistics transportation costs between the construction site temporary facilities and the maximum degree of closeness between the temporary facilities.Practical constraints such as restrictions and safety distances between temporary facilities establish a penalty function to impose penalties on layout schemes that do not meet the constraints.The particle swarm optimization algorithm that solves the multi-objective function is used to solve the objective function after the penalty function is applied,and the coordinates of the temporary facilities to be arranged are determined.Finally,by applying the construction site layout method of this paper to engineering examples,the practicability and effectiveness of the method are verified.
