SUMMARY:

Approval of the contract for Pre-Construction Phase Services for the John Wayne Airport Terminal Electrical Distribution Upgrades Project will modernize John Wayne Airport's Terminal complex electrical distribution system, which includes replacing aging switchgear and unit substations, providing provision for future microgrid/load shedding controls and monitoring system and modifying emergency distribution systems.

BACKGROUND INFORMATION:

John Wayne Airport (JWA), located approximately 35 miles south of Los Angeles, between the cities of Costa Mesa, Irvine and Newport Beach, is owned and operated by the County of Orange (County) and is the only commercial service airport in Orange County. JWA’s service area includes more than three million people within the 34 cities and unincorporated areas of Orange County. In 2022, approximately 11.3 million passengers were served.

The proposed JWA Terminal Electrical Distribution Upgrades Project (Project) proposes to replace the aging main terminal medium-voltage switchgear and the five unit substations - one in Terminal A, two in Terminal B, one in Parking A2 and one in Parking B2, which have over 20 years of use and are ending their design life. The 12 kilovolt distribution for the terminals will be re-fed from the new switchgear to the unit substations. In addition, the existing emergency systems will be upgraded to replace old air traffic service (ATS) in Terminals A and B and to separate emergency (life safety) loads from other loads per California Electrical Code Article 700.5(D) in Terminal A, Terminal B, Parking A2 and Parking B2, which currently have emergency power systems and ATS serving a combination of emergency and standby loads

On April 4, 2023, OC Public Works issued a Request for Proposal (RFP) for Construction Manager At- Risk Pre-Construction Services (Services) the Project. The RFP was advertised in several industry publications and on the County online bid system. One proposal was received and deemed responsive. The evaluation panel composed of members from OC Public Works scored the responsive proposal. See Attachment C for Memorandum of Recommendation and Evaluation Ranking Summary.
