地铁信号系统概算控制要点

Control Points of Preparing Budget for Subway Signal System

以信号系统为例,分析设计概算编制过程中经常出现的几类问题及原因,阐明在设计阶段编制出高质量的概算文件,加强投资控制,应在概算编制的"量、价、标准(依据、定额)"这些关键点上加以控制,确保概算的完整性、准确性、合理性,对加强整个地铁建设投资控制具有重要的现实意义。

Taking the signal system as an example, the paper analyzes the types of problems and reasons during the preparation of the design budget, and sets forth the budget preparation should deliver a high quality budget document in the design stage for strengthening investment control, and should control such key points as quantity, price and standard （norm and quota）, for ensuring the integrity, accuracy and rationality, which has an important practical significance to strengthen the investment control of entire subway construction.
