BIM Application Framework And Implementation Strategy Research In The Design And Construction Phase

The development of building information technology is a key factor in the sustainable,effective,healthy and rapid development of our country's construction industry.In addition,from the end of 2009 to today,to control the momentum of the soaring real estate market,the state has repeatedly introduced macro-control policies.Regions also introduce various detailed rules to control real estates.Currently national real estate fever is an indisputable fact.With the rise of human labor costs,the rise of material prices and the soaring of land prices,the real estate industry has been gradually shift to fine management of revenue-generating model from the original extensive and lucrative profits industry.In this model changing,developers who can't adapt fall down batches by batches.A group of outstanding developers survive after the sweep.In order to adapt to the new market competition,how to lower cost of the whole process which is from the beginning to delivery stage becomes a key concern of developers,in the environment of rising cost of manpower and various costs.At this time,many formed BIM application technologies from foreign countries have entered the developer's line of sight.When profits bringing by using BIM applications are more than costs,there is the motivation.BIM technology promotion from the government level is increasing in recent years.Standards began to develop.The application model gradually transforms into the owner-driven model from the previous design-driven model.Owners began to gradually accept BIM technology,and enjoy economic benefits bringing by using BIM.But we can't avoid saying,the current using range of BIM technology in the domestic engineering is very narrow.It is mainly used to achieve complex design of the building design,different professional model collision check.The application only focuses on the design stage.The application in the construction focuses on quantity measurement,site layout,construction simulation,safety,quality and schedule tracking monitoring.The application in supervision is also narrow,and it only uses for a certain stage of construction life cycle and is far from being performed in the whole life cycle of project.Through documents research,this paper analyzes the development of BIM theory and the application status in China and foreign countries.Further study the applications of BIM technology in design stage and construction stage.Compared the advantages before and after bringing in BIM technology.Research in establishing a BIM application framework which is appropriate for design and construction stages.Formulate corresponding application strategies.Through the actual case of introducing BIM technology application in Yangliujun project,research on how to implement parking spaces optimization,VR technology and other application strategies under an established BIM application framework.And get the corresponding results.Through the actual case of the introduction of BIM technology in Hangzhou Hengqi Kela Mansion Project,study how to apply strategy for outdoor pipeline integrated optimization under an established BIM application framework and achieve good result in using BIM to optimize outdoor integrated pipeline.Through the actual case of introducing BIM technology application in Shengli Primary School Xincheng Campus and its affiliated kindergarten,study how to implement application strategies of visualization application,conflict detection,3D pipeline integration,vertical clearance optimization,construction drawing auxiliary design,virtual simulation walkthrough,4D schedule simulation,construction inspection and other aspects.And get optimized application results of these aspects.The main conclusions of this paper are as follows.The BIM application framework and the implementation strategy which are researched in this paper are practical,operable and applicable.The practical operation case shows that it has good effect and huge economy.Overall,the application of Building Information Model(BIM)is the direction of the development of construction industry.Applying BIM in developments of commercial projects is of great significance.In the environment which has constant price rising and brutal market competition,to establish a commercial applied model which can cover a whole lifecycle of a construction and develop BIM technology applied in a full process is immeasurable in improving construction efficiency,saving construction costs,improving project quality,improving system operation and management reliability,saving operation and management cost and other aspects.
