Government-society joint venture mode (PPP mode) can solve the problems of capital shortage and government financial pressure in the construction process of smart cities. At the national level, the application of PPP mode in smart city construction projects is vigorously promoted. Based on this, this paper studies the operation and management mechanism of the PPP mode of smart city construction projects. In this paper, case analysis and quantitative analysis are adopted to illustrate the operation and management mechanism of the PPP mode of smart city construction projects. Through analysis, the feasibility and practicability of PPP model in smart city construction project management are illustrated. The innovation point and main contribution of this paper is to analyze the applicability and significance of using PPP mode in smart city construction projects, and to design the overall framework of PPP model for smart city construction projects. This paper puts forward the operation mechanism of the PPP model for smart city construction projects, and illustrates the implementation idea of promoting the PPP model for smart city construction projects with a classic case, which provides reference for the development of smart city construction projects.

In recent years, with the advent of digital economy, big data has been widely used in all walks of life. Building logistics has become a new source of profit for the construction industry. In this context, the BIM (Building Information Modeling) technology and Internet of things technology will bring new application value to building logistics management. This paper uses comparative analysis and case analysis to analyze the BIM technology and Internet of things technology in the era of big data in the construction industry, The main contribution of this paper is to analyze the new characteristics of building logistics management based on the BIM technology and logistics technology in the era of big data, build the logistics collaborative management platform based on big data and the BIM Technology, and analyze the logistics collaborative management platform based on big data. Finally, through the case analysis, it is concluded that the BIM technology and Internet of things technology have great application value in all aspects of construction logistics management in the era of big data.

In recent years, with the advent of the era of “Internet +”, the development trend of informatization and digitization exist all walks of life, BIM (building information model) as the construction industry the most advanced information and digital technology obtained the promotion and application of the government and the construction industry in our country, the application of new technology will bring a series of change, so the IPD(integrated project delivery) model appeared based on BIM technology, based on the full consideration under the network environment, it is necessary to make further improvement on the IPD model, that is the formation of the IPD mode as the core delivery, With BIM technology, “Internet +” related technology and network organization structure to support the improvement of the IPD management mode, and to analyze the basic principle and framework, operation mechanism and implementation process of the improvement of IPD model, then contrast analysis on the IPD mode before and after improve, finally to prove the improvement of IPD mode is feasible and scientific by the practical application of simulation.
