在拟建某项工程时,项目经过决策阶段确定后,设计阶段就成为工程的关键,它对某项工程的建设周期、工程造价、质量以及投资效果起着决定性的作用。 但在设计过程中,需要采用各种标准和定额。如有国家各部颁发的,也有所属部门制定的等等。以前在采用各种标准和定额时,往往从技术的角度考虑多,从经济的角度考虑少,有时甚至直接搬或套,没有从实际出发,结果造成技术与经济的不合理。 When a project is to be constructed, the design stage becomes the key of the project after the project is determined through the decision-making stage. It plays a decisive role in the construction period, project cost, quality and investment effect of a project. However, in the design process, the need for a variety of standards and quotas. If issued by ministries, but also have their own departments and so on. In the past, when adopting various standards and quotas, they often considered them from a technical point of view, considered less from an economic point of view, and sometimes even directly moved or arbitrarily did not proceed from reality, resulting in irrational technical and economic results.
