摘要:本工程为淮安市房管局办公楼建筑给水排水工程设计，其中一层是物业，一层是商业，其余均为办公室及客房，是一综合性民用建筑。楼层共十三层，各层功能见建筑图所示。钢砼框架结构（一、二级耐火等级），室内外高差为1.0米。

　　　给水系统：采用加压供水的方式，分为上下三个区：故一层至二层的裙房部分生活给水由市政给水管道直接供水，为市政直供区；三到八层为加压低区；九到十三层为加压高区。

　　　热水系统：采用太阳能热水器供应热水。

　　　消防系统：主要采用室内消火栓系统，火灾初期10min消防用水量由屋顶消防水箱供给，消防水箱的水源由生活水泵从生活水池抽取；10min后的消防启动消防水泵，从消防水池抽水供消火栓使用。

　　　排水系统：采用污、废水分流制，坐便器出水直接排入市政污水管网。排水系统采用螺旋消能排水管材，就近排入市政污水管网。雨水系统主要是屋面的雨水排除，宜按重力流设计。
