Lập kế hoạch & Dự toánCâu 299 / 360
Before excavating a trench for underground plumbing on a commercial site, which coordination step is most important for safety and to avoid utility strikes?
a.Order the fixtures
b.Set the water heater
c.Paint the walls
d.Have underground utilities located/marked (call the one-call center) and review the site utility plan
Giải thích
Contacting the regional one-call center to mark existing utilities, and reviewing the site utility plan, prevents striking gas, electric, or communication lines during excavation. This is both a safety requirement and a coordination step with other trades and utility owners. Locating utilities first avoids injury, outages, and costly repairs.
