浅析建筑防排烟新标准下的工程增量估算

Analysis of Engineering Incremental Estimation under the New Standard of Building Smoke Control

文章以2018年8月1日起开始实施《建筑防烟排烟系统技术标准》(GB 51251-2017)为背景,浅析引起设计变更的防排烟新标准条文并结合实际工程案例测算增加工程量,给出主要增加工程量的测算方法,供暖通与概、预算人员参考。

This article takes the implementation of Technical Standards for Building Smoke Control and Exhaust System(GB51251-2017)from August1,2018 as the background.Combining with practical engineering cases,this paper briefly analyses the new standard which mainly cause design changes,and calculates the increase of project volume.It also analyses the new code provisions for smoke management of change project measurement,and gives calculation method for HVAC and budgetary engineers to reference.
