Application And Research Of Price Index Adjustmentprice Difference Method For The Developer

Caused by rising prices of the contract price adjustment is an important content of construction contract management,its effect is good or bad will affect project cost accurate or not.In actual construction process,labor,materials and engineering equipment,rating per machine often has a larger price volatility,so how the tenderee in the tender documents made applicable price adjustment method,affect the interests of both parties contract.Now commonly used in the construction project price adjustment method is the cost information adjustment the price difference method,it has experienced a period of time application,began to highlight some issues which affect the adjustment effect.For example,the method is in turn pricing adjustment,is not a unified pricing adjustment,the afterthought adjustment method bring difficulty to process control and the mid-term settlement;When unit cost defects,need for inquiry,bargaining process to the unit cost;The differences of the parties to the contract for this happen is very outstanding;Pricing process is tedious.On the contrary,the method's application of price index adjustment the price difference is beneficial to strengthen the interim payment and simplified engineering settlement;The method of according to the price rise and fall's trend and carefully in advance,can reduce divergence between contracting parties when settlement period and make for the settlement and the engineering cost control;At the same time,it to the owner of the investment control and simplify the project settlement audit are highly beneficial.Based on the perspective of project employer,this paper studies the application of method of price index adjustment price difference.Firstly expounds the price adjustments related theory and analyzes influence of price index adjustment method's applying to the developer;Secondly analyzes each factor's principle of price adjustment formula,and the formula's application and questions needed to attention in the application process.Then,discusses the employer in the tender stage how to apply price index adjustment method;Final application project case illustrates respectively: the price adjustment formula of single and multiple price adjustment formula,cost information adjustment the price difference method of pricing process.Comparing with the above three kinds of adjustable results analysis and draw the following conclusion: The method of price index adjustment price difference of "single" formula directly applied to the domestic housing construction and decoration project can meet the requirements,but the "multiple" pricing formula's results than "single" formula's results are closer to the actual difference.On the analysis price index adjustment method's application,"multiple" formula is introduced to improve the pricing accuracy;Select adjustable factor is a key work,using sensitivity analysis and ABC analysis method to select the adjustable factor;Finally summarizes the application flow chart of "multiple" formula.
