Research On Life Cycle Management Of Construction Project Based On BIM

The construction industry is the pillar industry of the national economy and an important material production sector.The development of the construction industry can create enormous wealth for the society and provide a large number of jobs,and the output value of the construction industry plays an important role in the gross domestic product and improves people’s lives.Has a huge push.In recent years,the development of China’s construction industry is changing with each passing day.China’s infrastructure construction level has been in the leading position in the world.At present,China has become the world’s largest construction market,and large-scale buildings,especially ultra-high,ultra-deep and complex buildings in China’s construction industry.The proportion is getting bigger and bigger.How to carry out project management more efficiently has become an urgent problem to be solved in front of engineers.As a more scientific management method,life cycle management has attracted more and more people’s attention,and the rapid development of information technology has provided a continuous impetus to promote the application of BIM technology in life cycle management.In this context,this paper studies the development history and application status of BIM technology at home and abroad through literature research method and comparative analysis method.It systematically expounds the concept and connotation of BIM,and introduces the core characteristics of BIM and the widely used ones in detail.Several BIM software.At the same time,the life cycle management theory of the project and the life-cycle integrated management framework of the BIM-based construction project are introduced in detail,and the operation and maintenance phases of BIM in the planning and decision-making stage of the project,the construction phase of the project and the project delivery and use are analyzed.The practical application value.Through the comparison of the two management modes,the comprehensive management benefits such as the value added by the application of BIM technology and the quality,economic benefit and progress benefit generated by the project are analyzed.Find out the combination of BIM technology and life cycle management,and promote the development of life cycle management through the application of BIM technology.Combined with the case of Shanghai Rail Transit Line 17 project,the in-depth application of BIM technology in the preliminary design stage,construction drawing design and construction preparation stage,construction implementation stage and operation and maintenance stage is analyzed in detail.BIM application points include:architectural,structural professional modeling,pipeline relocation and road turnover simulation,site status simulation;BIM application points in the construction drawing design stage include:professional modeling,engineering quantity review,3D pipeline comprehensive design,Special design schemes,etc.;BIM application points in the construction preparation stage include:construction planning simulation,construction deepening design,installation and construction simulation,etc.;BIM application points in the construction implementation stage include virtual progress and actual progress comparison,PC facade 3D scanning,establishment of the completion model,etc.;BIM is used in the operation and maintenance phase to develop the operation and maintenance management platform.Through the application of BIM in the whole process of the project,it has achieved a series of goals such as optimizing the design plan,controlling the construction progress,reducing the cost,shortening the construction period and improving the quality,which greatly improved the efficiency of project management.Through multi-angle analysis,the paper concludes that life cycle management will become the mainstream management mode of project management in the future.BIM technology is more and more widely used in project life cycle management based on its advantages of visualization and simulation.The combination of the project has opened up a new path for project management and promoted the overall development of the construction industry.
