With the continuous progress and upgrading of technology,our country construction industry has also accelerated industrial transformation,promotes the popularization and application of assembly-type building mode,further improves the quality and efficiency of construction,but also provides strong technical support for the sustainable development of building industry.In order to ensure the construction quality of prefabricated buildings,further strengthen the optimization of construction schemes,effectively control construction costs,and practice the construction policy of green ecology and en-vironmental protection,BIM technology needs to be introduced to improve the construction work of prefabricated buildings.Based on prefabricated building construction,this paper studies the advantages of BIM technology,and explores the specific application of this technology in the construction process combined with specific cases,in order to provide more references for building construction work.
