Building engineering construction method based on BIM technology

Abstract

The invention relates to the technical field of building construction, and particularly discloses a building engineering construction method based on a BIM technology, and the method comprises the steps: obtaining a building digital twin model; performing multi-specialty collision detection on the building digital twin model for identifying conflict points of structures, electromechanics, curtain walls and decorations to obtain an optimized coordination model; time-energy consumption balance of different construction schemes is evaluated through a 4D progress-energy consumption integrated optimization model, and an optimal construction sequence and a green cost optimization list are obtained; obtaining a traceable prefabricated part; component positioning and mounting rules are embedded in the traceable prefabricated components and used for on-site AR guidance and control and deviation checking, and accurate mounting results are obtained; according to the method, the digital twinborn model is constructed by fusing laser scanning, design drawings and existing structure information in the early stage of construction, and unified collaboration of multiple professions such as structure, electromechanics, curtain walls and decoration is achieved. The design scheme is feasible in the implementation level, and the later reworking risk is effectively avoided.
