Summary: C Line Cathodic Protection Drawing Set

This is a technical drawing set prepared for the Los Angeles County Metropolitan Transportation Authority (Metro) depicting corrosion control and cathodic protection system specifications for the C Line (Passenger Line) transit project. The document consists of 20 detailed sheets providing site layouts, installation details, and equipment schedules across 16 stations and multiple facilities located throughout Los Angeles County, including Norwalk, Lakewood, Long Beach, Willowbrook, Avalon, Harbor, Crenshaw, Aviation/LAX, Mariposa, El Segundo, Douglas, and Redondo Beach stations, as well as associated Transit Control Center Buildings (TCCBs). The drawings were finalized on October 30, 2024, and were prepared with funding from the U.S. Department of Transportation Federal Transit Administration under the Federal Transit Act of 1964, supplemented by Los Angeles County and State of California tax revenues.

The drawings specify comprehensive cathodic protection upgrades including installation of magnesium anodes (48-pound units), replacement of electrical isolation components, installation of new test stations, reconnection of test wires, and replacement of shunts across multiple locations. Individual stations require varying quantities of anodes, ranging from 2 to 12 units per location. The technical specifications detail anode installation procedures, reference electrode configurations, electrical isolation methods, pin brazing connections for below-grade installations, and panel board test station layouts. All construction work must comply with NACE (National Association of Corrosion Engineers) standards, California Code of Regulations Title Eight, and CalOSHA permit requirements for excavations exceeding five feet in depth. Contractors are required to call Underground Service Alert (USA) 811 a minimum of 48 hours prior to commencing work and verify utility locations through field potholing procedures.

STEP 5 TEST THE CONNECTION WITH A HAMMER. THIS WILL ALSO REMOVE CERAMIC

FERRULE. DO NOT DAMAGE THREADS ON PIN.

NOTES:

1. FOR BURIED PIPE-TO-CABLE CONNECTIONS, THE DIRECT PIN BRAZE CONNECTION (NOT

THE THREADED STUD) SHALL BE USED ALONG WITH A ROYSTON HANDY CAP) OR EQUAL.
