Deliver and Enhance High Quality Efficient Services and Infrastructure
BACKGROUND
On January 14, 2020, Council awarded the Public Works Contract (Contract No. 2104A) for the Serra Substation Construction Project (Project) to the Newtron Group for the bid price of $4,987,510 plus a 10% contingency of $498,751 for a total authorized contract amount $5,486,261. The Serra Substation Construction Project is a rebuild of the existing substation, which has obsolete equipment nearing the end of its useful service life. The rebuild will allow Silicon Valley Power (SVP) to continue to provide service to customers while improving service reliability and system redundancy. Work includes replacing the existing single 16 MVA transformer bank and switchgear with two 20 MVA transformer banks, new switchgear, and control room that meets SVP's current standards. The site is physically constrained within the current lease of the property owner. The Public Works Contract consists of all required work to reconstruct the Serra Substation at the existing location along Lawrence Expressway.
On January 12, 2021, Council authorized the City Manager to execute Change Order No. 4 to add the replacement of the existing wood transmission poles with steel self-supporting transmission poles to mitigate field conflicts with new underground structures. Change Order No. 4 increased the authorized funding amount by $715,512 and additional contingency of $375,000 for a contract total not-to-exceed amount of $6,576,773.

The construction phase of the Project is at 75% of completion.
