  1. MEP sleeve layout before concrete pour checklist

    construction-hvac-mep

    MEP sleeves before a concrete pour are not a detail I like leaving to memory. Once the concrete is placed, every missed sleeve becomes core drilling, layout arguments, dust, noise, and a schedule hit that nobody budgete…

  2. 风管保温结露怎么处理,现场排查经验

    construction-hvac-mep

    风管结露很多时候不是简单"保温棉不够厚"。我处理过一个店铺项目,送风管外面一直有水珠,业主以为是空调漏水。后来拆开看,管道保温接缝没封严,吊顶里又有热湿空气,冷风一走,外表面温差太大就开始结露。 排查时我会先看三件事:风管表面有没有露点条件,保温层有没有破口和压扁,vapor barrier 接缝是不是连续。很多人只补一块保温棉,但铝箔胶带没压实,穿吊杆和支架的位置也没处理,水还是会从这些小地方出来。 还要看系统运行。送风温度压得太低…

  4. MEP coordination drawings: who catches clashes before rough-in?

    construction-hvac-mep

    On tight jobs, the clash is never just one trade. Duct wants the same ceiling space as sprinkler, plumbing needs slope, electrical has panels and runs, then the ceiling height is already tight before anyone starts rough…

  5. 旧房改造HVAC和水电先排哪一项比较稳

    construction-hvac-mep

    旧房一拆开,HVAC、水、电经常互相抢位置。duct 走哪里、panel 够不够、排水坡度够不够,前面没排清楚,后面 drywall 之前就会一直改。 我一般会先把大件和主管线位置确定下来,再谈细节,不然几个工种互相让位置很耗时间。你们做旧房改造时,HVAC 和水电一般怎么排顺序?
