工期短、造价低、质量好是人们对建设项目工程施工提出的三大基本要求。但是正像质量与成本互相关联、互相制约一样,工期与成本、成本与质量之间也是互相关联、互相制约的。在这三者之间寻求一种平衡关系,是建筑施工中时刻需要关注的科学和管理的艺术。 Short construction period, low cost and good quality are the three basic requirements put forward by people for construction project construction. However, just as quality and cost are interrelated and mutually restrained, duration and cost, cost and quality are also interrelated and mutually restrained. Seeking a balance between these three is the art of science and management that needs constant attention in construction.
