Planning & EstimatingQuestion 314 of 360
A bid schedule shows the plumbing rough-in must be complete before the concrete slab is poured. What does this tell you about coordination?
a.Plumbing can start any time
b.The concrete crew controls the plumbing design
c.The underground plumbing is a predecessor task that must finish and pass inspection before the slab pour, so it must be scheduled and inspected first
d.The slab pour has no effect on plumbing
Explanation
The underground plumbing is a predecessor to the slab; it must be installed, tested, and inspected before concrete covers it. Coordinating with the concrete crew and inspector so the underground passes on time keeps the pour on schedule. Missing this window forces either a delay or breaking the slab later.
