“限额设计”是工程设计阶段控制工程造价的重要手段。根据工程投资限额合理分配各专业设计投资比例,在确保工程功能要求的前提下,各专业按投资限额进行设计,保证估算,概算起到层层控制的作用,不突破造价限额。工程造价的合理确定和有效控制是工程建设管理的重要环节。控制工程造价的目的不仅在于控制项目投资不突破造价限额,更积极的意义在于合理使用人力、物力、财力以取得最好的投资效益。 工程经济效益的高低是衡量设计质量的重要标准之一,设计人员必须树立经济观念,实事求是。设计人员和工程经济人员应密切配合,认真执行限额设计严格控制工程 “Design of limits” is an important means of controlling the construction cost in the engineering design phase. Based on the project investment quota, the proportion of each professional design investment should be rationally allocated. Under the premise of ensuring the functional requirements of the project, all the professions should be designed according to the investment quotas to ensure that estimates and estimates take the role of layers of control without breaking the construction quotas. Reasonable determination of project cost and effective control of construction management is an important part. The purpose of controlling the construction cost is not only that the investment in the control project does not break the cost limit, but the more positive significance lies in the rational use of manpower, material resources and financial resources so as to obtain the best investment returns. The level of engineering economic benefits is one of the important criteria to measure the quality of design. Designers must establish economic concept and seek truth from facts. Designers and engineering personnel should work closely with the strict implementation of quota design strictly control the project
