Study On Application Of PPP To Utility Tunnels

With the high-speed development of urban construction, there highlights some problems such as "the road zipper", "spider web" in the process of traditional buried pipelines expansion, updating and maintenance. The utility tunnels construction became the mainly direction of new town construction and old town reconstruction. However, due to the utility tunnels construction needs huge funds, fiscal capacity is limited. There is the financing problem in the process of urban infrastructure construction. So PPP model has been generalized. The model can not only solve the financing difficult, but also introduce advanced management experience, share risks effectively.At present, urban infrastructure construction are still at an initial stage, the project construction lack of theoretical basis and practical guidance. Guarantee the successful implement of PPP projects become the key of the construction. This paper adopted the research idea of the combination of theory and practice, qualitative and quantitative, and analyzed the feasibility and application of PPP models in utility tunnels. Firstly, analysis the characteristic of the utility tunnels, the agreement character between PPP mode and utility tunnels and the superiority of PPP mode, to determine the feasibility of PPP to utility tunnels. Selected BOT mode, make the project operation framework. Then the paper puts forward three main difficulties which are project organization coordination management, toll pricing and risk management, and makes specific measures. Finally applies the proposed measures to the instance, analysis the feasibility of measures which can provide theoretical basis and practices guidance for the application of PPP model in utility tunnel construction.Through the above research content, this paper obtains some research achievements as follows:Analyzing the characteristic of the utility tunnels; Designing the project operation framework; Making measures to coordinate between the various units; Considering the interests of all parties, constructing the charge reference model; Proposing reasonable risk allocation recommendation and feasible risk response measures.
