在施工项目管理中,对工期、质量和成本的控制是项目管理的基本目标。同时,这三个要素之间也存在相互制约的关系:要提高质量就可能增加成本,要缩短工期也可能会增加成本。进行项目管理就是要处理好三者之间的关系,使之处于最佳状态,以达到工期短、质量优、成本低的目标,获得好的经济效益和社会效益。 In construction project management, the control of schedule, quality and cost is the basic goal of project management. At the same time, there are also mutual constraints between these three elements: To improve quality, it is possible to increase costs, and shortening the construction period may also increase costs. The project management is to handle the relationship between the three to make it in the best condition to achieve the goal of short construction period, excellent quality and low cost, and obtain good economic and social benefits.
