Analysis And Research Of The Method Of Calculation Of Uncertainty Cost On Construction Project

Construction projects are generally have a large-scale, a long construction period, andthe consumption of human, material and financial resources are more than others, itcomplicated and have many influencing factors which made the difficulty of project cost ishigh and before the end of the project it’s completely sure, but building products is pricingprior which need determined before the bidding project cost, this needs to do the project costforecast, the cost of the project predict level is not only related to whether the project biddingstage win the bid and also affect to the profits after successful. Of course, engineering profitsand project cost management level also inseparable, no matter how correct and advanced ofthe project cost calculation method, the project cost also will inevitably suffer project costmanagement and control effects, the project cost is forecasting in a enterprise normalconstruction condition and in a reasonable project cost management environment certain, thelevel of project cost management has a decisive impact on the project cost, the exact extent ofthe project cost budget, determined by the method of calculation and management level of theproject cost, In order to improve project profits, we need to strengthen the management andcontrol of the project cost.It is pointed in this thesis that the project cost could not be confirmed before the projectis completed through the studies on the structures and characteristics of the project cost andthe studies on the pricing mode and valuation basis of the project cost, and the analysis of theuncertainty factors which will cause the project cost being not confirmed. Thus it is notappropriate for us to express the project cost as a single value. It should be expressed as a costrange under the condition of certain probability. For this, a calculation mode which is used tocalculate the uncertainty project cost is given in this thesis. During the confirmation of theuncertainty project cost, an inappropriate view point is revised in the process of theconfirmation of the project period when the traditional method of the project evaluation and review technique is used. A calculation method which is used to calculate the comprehensiveunit price of the project under the mode of resilience detailed list valuation is also raised inthis thesis. Not only that, the sensitivity analysis is also affected separately to the uncertaintyperiod and the uncertainty comprehensive unit price for their own uncertainty influencefactors. To determine their main influence factors, thereby it can make the uncertainty periodand the uncertainty of the comprehensive unit price control in view, and it also can make theproject cost management and control better realized.
