Action on Award of a Public Works Contract for the Laurelwood Junction Transmission Line Extension Project to Henkels & McCoy West, LLC, for a Not-to-Exceed Amount of $883,183, Inclusive of a 15% Contingency, Funded by the Laurelwood Substation Capital Improvement Project (CIP No. 2443) Budget

Summary

The City of Santa Clara is awarding a public works contract for the Laurelwood Junction Transmission Line Extension Project (CIP No. 2443) to Henkels & McCoy West, LLC, for a not-to-exceed amount of $883,183, which includes a 15% contingency. This project involves the extension of a transmission line, including excavation, installation of new structure foundations (P0553, P0554), framing of steel poles, and the stringing and termination of new 715 ACCR “Stilt” conductors. It also includes transferring existing 954 AAC “Magnolia” conductors and removing an existing transmission structure (KCC 20).

Key aspects of the work include comprehensive site preparation, landscaping restoration, traffic control, and strict environmental and archaeological monitoring. All ground disturbance requires archaeological and Tribal monitoring, with specific excavation methods and allowances totaling $250,000 for potential archaeological discoveries and unforeseen work. The contractor must complete the work within 80 working days from the Notice to Proceed, with liquidated damages of $2,800 per day for unexcused delays. Special handling and 3M training are required for ACCR conductor installation, and extensive coordination for de-energization of transmission lines is mandated, with notice periods up to 90 days for complex outages.

Citizen Impact

This project will modernize and extend the city's electrical transmission infrastructure, enhancing reliability and capacity. Residents may experience temporary traffic disruptions and noise during construction, particularly during excavation and overhead line work, but traffic control plans will be implemented. The project also ensures the protection of cultural resources through dedicated monitoring during ground disturbance.
