Network Facility Structural Survey, Seattle City Light
CivilTech conducted structural inspections of approximately 120 underground utility vaults located in downtown Seattle. Confined space certification for our inspectors was required to enter the hot electrical vaults. The vaults were surveyed for structural deficiencies such as cracks in concrete or masonry walls and roofs, spalls, exposed and corroded reinforcing and steel members, wall deflection, loose and missing connections, and water intrusion. All deficiencies were identified, logged, measured, mapped, and photographed then compiled in a final report with repair, replacement or monitoring recommendations. Priority ratings were assigned to each vault depending on its assessed condition.
