Research On Target Management Of Assembled Residential Project Based On BIM

"Strengthening the application of information technology in assembled residential buildings,promoting the design,production,transportation,assembly and whole life management of BIM-based construction projects,to promote industrial construction," said in the 2016-2020 outline for the development of informatization in the construction industry.",it can be seen that the national policy is to vigorously implement BIM based assembly residential construction,which shows that the traditional management model construction model is no longer adapted to the rapid development of the times,it will be replaced by the emerging model of assembly-type residential construction.However,there are many restricting factors in the development of assembled residential buildings,which lead to many problems in the process of target management in the construction stage of the project.Taking "research on the target management of assembled residential projects based on BIM-taking a project in Dalian as an example" as the research direction,through the literature research method and case study method,this paper studies and studies the advantages,characteristics,present situation and application of BIM,assembled residential building construction technology,and the basic theory of project target management,Then it analyzes the restricting factors of the assembly type residential development project.This paper introduces the application value of BIM in the Assembly house under the general contract mode of engineering,and then probes into the application of BIM in safety,quality,schedule and cost target management.Finally,a case study of a project in Dalian is cited,which embodies the advanced nature and superiority of BIM in the target management of assembled residential buildings,and ensures the maximization of project target management benefits.The application process based on BIM in the target management of assembled residential buildings can be summed up as:First,BIM can be in the design and construction phase model creation process will be designed drawings related professional conflict problem check out,easy to optimize the design,reduce the cost of the project.According to the three-dimensional parametric display of BIM model and the size of the hole,reasonable edge protection and template bracket are set up.Second,BIM visualization can optimize the layout of the site,pipeline integrated layout,etc.,can create three-dimensional visualization site layout,optimize the stacking position of the components,reasonable field cloth,reduce the handling of two times.Third,BIM can carry out structural parts hoisting,node construction and other dynamic construction simulation,the construction schedule project into the model,the time setting of the structure accessories,showing three-dimensional visualization construction;Third,BIM can establish civil,steel bar,installation professional BIM model,based on the above building information model can quickly obtain engineering information,according to the information data for multi-calculation comparative analysis,guide the field material preparation,reasonable distribution of labor force,improve the efficiency of project cost management.BIM and assembled residential construction technology as the two hottest topics at present,will certainly cause great changes in the construction industry,but also promote the rapid development of China's economy.
