| In the context of China’s large population with increasingly scarce land resources in the core areas of the city,facing the enormous pressure caused by keeping the red line of cultivated land and continuously investing in urban infrastructure construction,the land transfer mode of major cities has been adjusted to the multi-agent co-development,which leads to waste of space resources.Therefore,in the public construction group engineering design and construction urgently need to co-ordinate and coordinate the management method,so that the public construction project would be more rational and effective.Beijing CBD public construction group planning construction area of about 4.1 million m2,with the land transfer and the project construction at the same time.In order to make full use of limited resources,we can work through the collaborative management of collaborative management and construction management,and data analysis shows that the integration of integrated management based on the integration of the new system is far greater than the benefits of integration before the independent operation of the various developers.In summary,the main contents of this paper are as follows:(1)In view of the independent support of various projects caused by multi-party investment entities,the construction of independent construction caused the damage of underground use area of ??the project,thus affecting the project post-income problem,putforward the Beijing CBD public construction group design collaborative management strategy,Depth of the adjacent projects between the adjacent earth excavation temporary support and structural support between the mutual support to achieve the project to increase the area of??underground space to solve the project to enhance the intensity of land use.(2)The construction site caused by the multi-party investment entity is chaotic and disorderly,and the construction period cannot be controlled to be prolonged.The project cannot be delivered on time,thus affecting the project’s post-income problem,and put forward the cooperative management strategy of Beijing CBD public construction group.Order to carry out,to reduce the duration,to solve the project cannot be completed on time delivery issues.(3)In order to solve the problem of quantitative research on the project’s permanent value promotion,this paper puts forward the method of calculating the permanent value of Beijing CBD public construction group by cost method and income method,and quantifying the permanent value of the project analysis.To achieve a precise calculation to solve theproblem of the permanent value of the project.(4)In order to quantitatively study the value of the project’s time-enhancing value,this paper puts forward the method of establishing the valuation value of the Beijing CBD public construction group by using the future income forecast method,and quantitatively analyzes the value of project timeliness.Which realizes the accurate calculation and solves the quantification problem of project timeliness value.In this paper,through the practical large-scale project case,the synergy theory is applied to the project between the large projects,through the collaborative management between the project to solve the actual project by different openers at the same time to focus on the construction of the management of chaos and land resources Inefficient use and other issues.And analyzes the enhancement of the economic value after applying the cooperative theory in the specific case,and discusses the high efficiency and profitability of the construction management system of the large public building group based on the cooperative theory. |
