Cost Adjustment Study Of Engineering Change Based On Quantity List

With the rapid development of economy and the deepening of the urban modernization,the construction project of the size and number also is in rapid growth,the construction has become a big presence in the national economy.Engineering changes will inevitably occur during the construction process,and more than 95% of the engineering changes will basically result in the change of the bill of quantities.Therefore,it is necessary to study the cost adjustment of engineering change.This article first introduces the research status both at home and abroad,and engineering change were summarized and the related concepts,analyzes the cause of change and the existing form,identify the engineering change influence factors.Then explain the definition of project cost and the cost of bill of quantities mode and characteristics of the combination of China construction 7 engineering bureau of actual case,in under the mode of pricing by bill of quantities project cost change caused by engineering change,found the problem:The project change approval procedure is not strict,the project change plan chooses not the optimal,the project quantity list describes to make the dispute,the contract agreement is unclear,the lack of dispute resolution organization and so on.Finally puts forward his own opinion and the suggestion,the specific expounded at the different stages of the project construction complete various steps,with getting to solve engineering change cost adjustment difficulties,poor solve the problem.For example will check whether the change reason is reasonable to decide whether to change,give full consideration to the impact on the cost and the project itself,and the choice of the optimal change plan,standardize pricing based on the engineering change process,the contract based on the engineering change of the price adjustment provisions,legal means as pricing of legal protection,etc.,the engineering change cost adjustment caused by standardization,or form a complete set of adjustment means and methods,used to guide the engineering change caused by the cost of the project adjustment,promote the engineering construction in order to achieve the purpose of the healthy,rapid and orderly development.
