The Investment Control Of Express Track Train From Tianjin Downtown To Binhai

The project of express track train from Tianjin downtown to Binhai new developed area is the key project in Tianjin(abbreviated as Jin-Bin project in the context).The total investment of first stage has been estimated as 6,372.09 millions yuan. The highest speed deigned is 100km/h.The project went into operation on May 18,2001, and was builded open to traffic on October 1,2003.In the project operation, many properties should be removed away and the project need to be divided into many segments. It is also professional, complicated and urgent. It has many parallel projects, and it is changeful. The owner constructs a set of flexible and feasible investment control system including many control ceiling of different levels in order to make the investment control easier. This article analyzed the construction theories and operation effects of the system, pointed out the direction to improve and of make the beneficial experience for the next stage of project and other public projects.The dynamic, all-points and all-process controls were the guide and theory base of the system, which need a capable organization system to carry it out. It was made up of subdividing patterns of control ceiling, organization structure and function arrangement. All of them support each other to achieve the goal so that the obligation right are clear and subdivision of the work are strict.It is more possible to reduce the cost in engineering and preparing stage than that in construction stage, so more attention should be paid to the engineering stage. Jin-Bin project use the valuation engineering and limit design ideas in the engineering control. It also chose the suitable materials, equipment and the engineering solutions, and drawn up the work in engineering stage and check process.Jin-Bin project with very long road need great investment and complicated technological processes. Several billions yuan of investment need to be contracted...
