毕业设计(论文)-工程变更对造价的影响及控制_精品.doc

摘要 在工程实践过程中，由于业主要求、设计和环境等原因工程变更经常发生，工程变更的费用也是工程造价的控制的重点。文章从实践中的工程出发，归纳和总结工程变更对建设项目造价控制的影响因素。75％ 以上，因此设计质量对整个工程建设的效益是极为重要的。如果在设计阶段考虑不周，势必会在以后施工过程中出现工程变更，包括设计变更、施工条件变更以及原招标文件和工程量清单中未包括的“新增工程项目”等，从而对工程造价带来影响，使工程项目目标控制极为不利。因此，程设计阶段应充分考虑各种可能情况，以加强对工程变更的控制，从而达到控制工程造价的目的。 关键词： ABSTRACT This article on the project change and building cost of projectss close union, as well as the question which and the solution way exists to the construction process in elaborates, achieves the scientific management active control investment the goal. In recent years, items of basic constructions move of bid has hastened the consummation, but in the construction process the project changes situation are many, is also very big to building cost of projectss influence, that determined that reasonably the change the project cost, controls the entire project effectively the building cost of projects, to maintains the contract fulfillment the solemnity and just principle especially important. In project practice process, because the owner requests, reason project changes and so on design and environment occurs frequently, the project changes expense is also the building cost of projects control key point. The article embarks from practice project, induction and summary project change to items of basic construction cost control influencing factor. Building cost of projects control penetration in project construction entire process, but before the key lies in the construction the investment decision and the design stage, indicated according to the related statistical data, policy-making and design jie section influence building cost of projects degree above 75%, therefore the design quality to the entire engineering constructions benefit is the great importance. If in the design stage consideration week, will not present the project change inevitably in the later construction process, including the design alteration, in the execution conditions change as well as the original tender document and
