This article combines the construction of the office refrigeration mechanical room of the Shenzhen Huide Building Project, analyzes the current technical difficulties in the construction of electrical & mechanical equipment pipelines in the large mechanical room, and proposes a new set of DMBP prefabricated mechanical room construction technology from the perspectives of cost saving, efficient construction, environmental protection and energy saving, which will be processed on-site. The operation is transferred the on-site manufacture work to the digital processing base for digital production, and the prefabricated components are transported to the site for assembly. By focusing on the four core of dmbp, the paper realizes a new construction mode of the machine room for off-site prefabrication and on-site assembly in five stages: deepening design, material procurement, prefabrication, loading and transportation, and field assembly, and providing technical support for the construction of mechanical and electrical equipment pipelines of the assembly machine room.

Based on the analysis of the current domestic construction enterprise application plus point, unified concept hierarchy on the basis of using AHP method to the construction of enterprise application plus point the value of the combination of qualitative and quantitative analysis, the value of the construction enterprise application plus point weights for construction enterprise is revealed.Correct BIM implementation plan and implement route were provided, in order to promote the concept of BIM landing in China.
