1估算及设计优化方案编制难点分析工程设计阶段,业主的工作重点在于有效的控制设计概算不超过投资限额,主要是编制合理的项目估算及进行设计方案的优化调整。作为中介方,主要是编制合理的项目估算,通过投资限额,项目概算,项目估算来全面了解项目成本,进而控制项目成本,并协助委托方及设计人实施设计方案和施工图设计的优化并利用价值工程对设计方案进行评估,进行限额设计,搞标准化设计。(1)方案预算阶段,根据同类工程项目的单位造价及本项目的特
1 Estimation and Design Optimization Project Preparation Difficulties Analysis During the engineering design phase, the focus of the work of the owner is to effectively control the design budget does not exceed the investment limit, mainly to prepare a reasonable project estimates and optimize the design adjustment. As an intermediary, it is mainly necessary to formulate reasonable project estimates, fully understand the project costs through investment quotas, project estimates and project estimates so as to control the project costs and assist the commissioning party and designers in the optimization and utilization of design plans and construction drawing designs Value Engineering to evaluate the design, the limit design, engage in standardized design.
