Planning & EstimatingQuestion 287 of 360
A restaurant plan calls for eight identical mop-sink rough-ins. Each rough-in needs 1 P-trap, 1 trap adapter, and 2 drop-ear elbows. How many drop-ear elbows go on the takeoff?
a.8
b.10
c.12
d.16
Explanation
Two drop-ear elbows per rough-in times eight rough-ins equals 2 × 8 = 16. When many identical assemblies repeat, multiply the per-unit fitting count by the quantity. Building a per-assembly parts list first makes repetitive takeoffs fast and accurate.
