BIM技术在南京市仙林污水处理厂异地扩建工程EPC总承包项目中的应用OACSTPCD

Vigorously developing the digital economy and building a digital China is an important support for building a new competitive advantage for the country.The report of the 20 th National Congress of the Communist Party of China proposes"accelerate the development of the digital economy and promote the deep integration of the digital economy and the real economy".Digitization can effectively drive the intelligent upgrading of production and service systems,promote the extension and expansion of industrial chains and value chains,and promote integrated development.It is an inevitable choice for the transformation and upgrading of the real economy.Building information modeling(BIM)technology,as one of the digital technologies,BIM technology has the characteristics of visualization,simulation,coordination,optimization,etc.The design and implementation of wastewater treatment plant(WWTP)expansion projects need to consider various factors,such as terrain,climate,hydrology,etc.,as well as process flow,equipment selection,construction organization,and other issues,which require higher quality design and implementation skills.Traditional design methods are not only inefficient,but also prone to errors.In recent years,with the continuous development of BIM technology and the widespread application of open-source graphical programming software Dynamo in BIM,traditional design has been parameterized through BIM technology in design to achieve more efficient and accurate water plant design.The application background of BIM technology in WWTPs is mainly to overcome limitations of traditional two-dimensional design,improve design and construction efficiency,realize data sharing and collaborative work,and finally achieve the purpose of improving production efficiency and reducing costs.This paper elaborates on the application of BIM technology in the EPC general contract project of Nanjing Xianlin WWTP from four aspects,namely the overview of the project along with its significant,early-stage BIM planning;the application of BIM technology in all respects and the economic and social benefits generated by BIM technology in this project,which significantly enhances the work efficiency of various specialties,strengthens the collaborative design among different specialties,avoids and resolves pipeline collision and other issues in advance,and accumulates the application of the entire life cycle of EPC general contracting projects led by design.
