Study On The Optimization Of Settlement Under The Bill Of Quantities Pricing Mode Based On The Perspective Of The Developer

With the acceleration of economic globalization and the rapid development of China's economy,the number and scale of China's construction projects are expanding rapidly,the management mode of construction projects is gradually in line with the international standards,and the way of project pricing is gradually changing from the initial quota pricing mode to the bill of quantities pricing mode.The fixed price pricing model based on government-guided prices has been unable to adapt to the development of the society.The application of bill of quantities pricing model fully meets the demand of market pricing,realizes the reasonable allocation of risks,and embodies the characteristics of market competitiveness.Under the mode of bill of quantities pricing,there are three contract modes,namely,unit price contract,total price contract and cost plus remuneration contract.Unit price contract and total price contract are two forms widely used in engineering construction projects.The difference between them lies in the adjustability of engineering quantity and comprehensive unit price as well as the division of risk scope.Unit price contract,finally included in the settlement quantity can be according to the actual quantity included in the project implementation process,comprehensive unit price when changes beyond a certain range of quantities can be adjusted in accordance with the provisions of the contract,the main material of due to market volatility of the price can be adjusted according to the contract way;Under the total price contract,in addition to the actual increase or decrease of the project amount caused by the change of visa,other contract quantities are taken as the basis for completion settlement.The comprehensive unit price cannot be adjusted,and the price of the main materials caused by market fluctuations can also be adjusted.Project completion settlement is a crucial link in construction project cost control,and how to use the characteristics of bill of quantities to optimize the settlement method,so as to achieve effective control of project cost has become particularly important.Firstly,this paper introduces the current situation of the parallel valuation of quota valuation and bill of quantities in China,compares the characteristics of the two valuation methods and their application in practical cases,and proves that the bill of quantities valuation model is more suitable for the current situation than the bill of quantities valuation model.The concept and valuation principle of bill of quantities mode are summarized.The function of project settlement in project cost is expounded.Based on developer point of view,in view of the problems that exist in the settlement,combined with the actual cases,the optimization research,the research content mainly from three aspects:one is that the unit price contract,abandoned the past with the method of actual quantities included in the settlement,boldly put forward the base contract quantities,when actual occurred more than contract a range of quantities of quantities,the beyond part of fortifying the increase or decrease in the base and included in the settlement of the idea.By studying the influence of different values of this magnitude on the project cost,the optimal value range of this magnitude is obtained.Second,under the unit price contract and the total price contract,compare the influence of different ways of adjusting the difference of main materials on the project cost in the case of price fluctuation,and find the most suitable way of adjusting the difference of materials to control the project cost;Third,under all contract modes,visa change is an important factor affecting the project cost,so it is imperative to develop a complete set of visa change process and form outcome documents.Through the above research,the purpose of optimizing the project settlement method and effectively controlling the project cost is achieved.
