recommendation
RECOMMENDATION: Recommend to the Board of Directors to:
A. Approve a Service Contract to AMTEK Construction for P1 Building A Feeder Cables Replacement (MP-337), for 480V feeder cables, per Specification No. S-2021-1261BD, for a total amount not to exceed $356,333; and

body
BACKGROUND
Plant No. 1 Maintenance Building A houses the rebuild shop support facilities and equipment. The rebuild shop is a support function of the Orange County Sanitation District (OC San) where major mechanical equipment such as pumps, valves, and structural components are rebuilt or fabricated. Electrical power to Building A is fed from a power building located within Plant No. 1.
RELEVANT STANDARDS
• Protect OC San assets
• 24/7/365 treatment plant reliability
• Maintain a proactive asset management program
PROBLEM
Routine predictive maintenance testing discovered that the insulation on the feeder cables for Plant No. 1 Maintenance Building A is failing. The cable was taken out of service to prevent a catastrophic cable failure.
PROPOSED SOLUTION
Replace existing feeder cables to restore full utility to the rebuild shop facilities.
TIMING CONCERNS
Proceeding in a timely fashion is recommended to prevent operational disruption and delays. Currently, the rebuild shop is running with a lower capacity temporary arrangement using the remaining parallel conductors of the original feed.
RAMIFICATIONS OF NOT TAKING ACTION
Not acting will impact the ability of the rebuild shop to overhaul and repair plant assets. There is also a potential for a prolonged outage due to catastrophic cable failure of the remaining cable system. Catastrophic cable failures can damage additional equipment and create more expensive emergency repair situations.
