长期以来,工程部门普遍忽视了建设项目前期阶段的成本控制的最佳时期,这会对招标和施工阶段的项目完成时的价格造成一些影响,尤其是施工合同价格会发生变化,在设计和实施阶段的工程设计变更受各种因素的影响,例如工程变更频繁本文针对提出的一系列的问题,对工程变更的原因和影响整个工程造价的因素进行系统的研究,具有十分重要的意义。 For a long time, engineering departments have generally overlooked the best period of cost control in the early stage of construction projects, which will have some impact on the bidding and completion of construction projects. In particular, the price of construction contracts will change. In designing and implementing The engineering design change of the stage is affected by various factors, such as the frequent engineering changes. In this paper, a series of questions are put forward. It is of great significance to systematically study the causes of engineering changes and the factors that affect the whole project cost.
