West Coast Highway Joint Manhole & Valve Adjustments (Project No. 24R09) – Notice of Completion for Contract No. 9417-1 ABSTRACT:
On January 9, 2024, the City Council awarded Contract No. 9417-1 for the West Coast Highway Joint Manhole & Valve Adjustments project to R.J. Noble Company. The project lowered and raised manholes and valve boxes for both the City of Newport Beach and the Orange County Sanitation District, and was performed in conjunction with the pavement rehabilitation by Caltrans along West Coast Highway between Jamboree Road and the Santa Ana River bridge. The work is now complete and staff requests City Council acceptance and close out of the contract.
RECOMMENDATION:
a) Accept the completed work and authorize the City Clerk to file a Notice of Completion for the project.

The final total contract amount was $1,020,426.22, which was approximately 10.6% higher than the original bid amount. This cost increase was primarily due to a need to modify the construction trucks and equipment to reduce the back-up alarm noise because of the required night work next to residential areas; additional slip cans installed at City water valve boxes; further concrete improvements along West Coast Highway; as well as OC San and other outside agencies requesting additional facilities grade adjustments.
A summary of the project schedule milestones is as follows:

December 5, 2024
The long period between lowering manholes/valves at the start of the project and raising them again at the end of the project was due to the duration of the pavement rehabilitation work performed by Caltrans. Facilities were lowered in March and April of 2024 and raised in October through December of 2024.
