Rapid Assessment Of Construction Engineering Based On Characteristic Parameters

Construction industry investment cycle is long,the investment amount is large,for the influence of the social development is also very profound,and in the field of the industry,construction industry valuation system construction is particularly important,it not only for the improvement of China’s construction industry has an important meaning,for our country construction enterprise established his own core competitiveness also has a far-reaching influence.This article through to the domestic construction project investment estimation of the corresponding method to compare and research,find out the current our country in building project rapid investment estimation,and on this basis,put forward the construction rapid appraisal of characteristic parameters of basic theories and thoughts,and using example respectively established characteristic parameter fast valuation valuation model and multiple regression analysis model,and use the predicted results of the two basic model,build up the model of construction project investment estimation based on characteristic parameter.On the one hand,make readers to better clear under the characteristic parameter of building the advantage of rapid appraisal system,on the other hand,also in order to better and more effective grasp of the construction quality and cost control in engineering construction in China,the greatest degree of advancing our country engineering construction of the evaluation of the overall project and efficiency.Research results show that:first,China’s building engineering valuation theory and professional skills are very scarce,and the evaluation method is relatively backward,the characteristic parameter of building engineering valuation can quickly improve enterprise competitiveness,improve the work efficiency,for the development of construction industry in the future in China has a huge driving force and important meaning;Second,the characteristic parameter of building engineering fast appraisal system established in the process,the determination of characteristic parameter index should follow the basic principles of quantitative,and,to use the appropriate mathematical thinking mode to build obeys the law of engineering appraisal mathematical model;Third,the characteristic parameter of building engineering valuation can quickly better completion and implementation of construction project cost prediction,but limited by the objective factors,the specific application of investment estimation still exist some limitations and shortcomings;Fourth,in view of the characteristic parameters of rapidly establishing evaluation system of multiple regression testing,the results show that the modeling samples and test like this,its error is very small,the characteristic parameter of the multiple regression model with good performance,can achieve the project cost more accurate predictions;Fifth,Characteristic parameter of building fast value selection of indicators should be comprehensive and accurate,and in addition,in the construction of the model,should guarantee the number of samples,rely on a large number of sample data as the basic support,to better to determine the characteristic parameters for the corresponding influence of the project cost.
