论工程变更与造价控制（Engineering change and cost control） This paper analyzes the influencing factors of engineering change, introduces the management and treatment principles of engineering change, and expounds the cost control of engineering change for reference. Keywords engineering change; influence factor; management; treatment principle; cost control; Due to limitations of the early work of the project, some of the actual situation and the original design documents appear inconsistent and found the original design errors, omissions or for other objective factors and change the original design scheme, structure, quantity or adjustment of the original contract work content often in practice, which leads to the engineering change. Any of the parties involved in the construction of the project, including the owner, the engineer, the contractor and the design party, may, as long as the foregoing has occurred in the implementation of the works, change the project accordingly. Any change in the project will affect the normal construction operation of the project, and it will affect the time limit, cost and cost, increase the investment of the project, and then affect the income of the projects investors. Therefore, the engineering change will directly increase the capital input of the project, which will make the investment out of control and affect the investment efficiency of the construction project. Frequent engineering changes will increase and disrupt the normal working steps and contents of the owner and the contractor, organize and coordinate the workload will increase the supervision engineer, are unfavorable to the contract management and quality control, increase the difficulty and complexity of project management, and indirectly led to increase the project cost. In recent years, with the development of Chinas economic construction and the expansion of opening to the outside world, a large number of industrial and civil buildings and infrastructure construction proj
