An Engineering Study To Demonstrate The Project PPP Based On The Development Of Municipal Administration

Based on the analysis of PPP projects in Zhengzhou City, the following conclusions are drawn from the analysis of the value- at- money evaluation, transaction structure, contract system, and procurement methods of the demonstration projects:1, The empirical project divides the value- at- money evaluation into six areas, such as life cycle, risk management, output performance, the role of market mechanism, the ability of government agencies, objectives can be achieved. And the PPP model and the traditional procurement model is compared and scored. The final PPP model score 86.21, the Government's traditional procurement model score 57.84. Thus from the quantitative dimension, the PPP model is far superior to the traditional government procurement model.2, The installation costs of the empirical project construction uses the rate of tender, bill of quantities valuation way to the final audit of the City Audit Bureau of the construction and installation costs as the base to float the proportion of concessions, reasonable profit and annual discount rate for the tender base bid.(8.20%) of the total market investment is subject to the upper limit of the purchase, by the full competition of various social capital, the construction and installation fee concessions to fall(except for railway construction projects), and within a certain range of reasonable profits rate and the annual discount rate to further reduce the cost of government procurement services. And ultimately determine the construction and installation costs of the proportion should not fall below 3%(including), the reasonable profit margin is not more than 8.20%(including), the annual discount rate is not higher than 5.97%(including).3, Combined with the actual situation of the project, the project operation and maintenance unit price are: municipal roads, bridges, lighting: 10 yuan / m2, landscaping: 7.27 yuan / m2, cleaning: 5 yuan / m2, The fee of street lighting is settled according to the invoice issued by the power company every year, and it does not include the traffic engineering operation and maintenance cost. And finally concluded that the annual operating performance service fee excluding electricity costs is 26.73 million yuan.4. According to the principle of charging government fees, the internal rate of return of the project is 5.62% under the direct payment method and 6.14% of the total investment of the project under the equal payment method. Therefore, the project adopts the way of the equal payment to pay the government to purchase service charges.5, The initial design of this demonstration project investment is 7.9 billion yuan, and ultimately determine the franchise period is 14-year(of which the construction period is 2-year), the internal rate of return calculated by 8.2%. The government annual availability service fees is about 1.07 billion yuan, About 12.8 billion yuan of service fee is required to pay for usability.6, Because there is no perfect pre-construction drawings, construction and installation costs to determine the core principle is based on the actual settlement, taking into account the proportion of concessions. The cost adjustment in the process is mainly based on the Code of Valuation of Construction Engineering Quantity List, in which the labor cost adjustment ratio is ± 10% and the material cost is ± 5%. The transportation distance of the commercial concrete, commercial asphalt concrete, cement stabilized soil and gravel shall not exceed 10km; the construction waste, sinopac, earthwork and so on shall be counted as 24.15(before tax) yuan / m3. the number of days Full-frame use generally taken by 70 days.
