Construction site arrangement optimization method and system based on BIM + GIS

Abstract

The invention discloses a construction site arrangement optimization method and system based on BIM + GIS, and belongs to the field of constructional engineering informatization. The method comprises the steps that firstly, a BIM model family library of various facilities needed by a construction site and GIS models of the construction site and the surrounding environment are constructed, and then the BIM model family library and the GIS models are fused; and establishing a construction site arrangement optimization multi-objective function by utilizing an SLP method based on the fused model, and solving an optimal solution of the construction site arrangement optimization multi-objective function by taking the minimum weighted value of the sum of the occupied areas of the various facilities and the sum of the logistics costs of the various facilities as a target and combining constraint conditions. According to the method, the rationality and controllability of arrangement of various temporary facilities on the construction site are analyzed and optimized, the construction transportation cost and the temporary land area are reduced, various adjustments are carried out on the arrangement of the construction site, a feasible optimized arrangement scheme is provided, and reference can be provided for optimization of similar engineering site arrangement.

Description

technical field [0001] The invention belongs to the field of construction engineering informatization, and more specifically relates to a BIM+GIS-based construction site layout optimization method and system. Background technique [0002] The layout of the construction site is an important part of the project construction preparation work, which needs to be considered in combination with green space restrictions, cultivated land restrictions, planning red lines, safety requirements, various temporary land use indicators, logistics intensity and logistics costs between temporary buildings, etc. Factors can effectively carry out construction site layout, and create conditions and foundations for subsequent construction management, cost control, and safety management. [0003] The site layout design in the actual implementation of the project at this stage is mostly determined by the site technical director based on the CAD drawings combined with his own experience and the actu...
