RECOMMENDATION
Recommendation
It is recommended that the City Council adopt a resolution awarding a construction contract to Seton Pacific Construction of San Francisco, California for the Antoinette Lane Underground Utility District Project, Phase 1 (Project No. st1702a) in an amount not to exceed $2,019,667, authorizing a total construction budget of $ 2,221,634, and approving Budget Amendment Number 19.049.
Body
BACKGROUND/DISCUSSION
The Antoinette Underground Utility District phase 1 project will move the overhead power and communication utilities along the frontage of the planned Community Civic Center Campus and Police Department to an underground trench in Antoinette Lane. The City Council adopted Ordinance 1540-2017 on July 26, 2017 to formally establish the underground district in accordance with California Public Utilities Commission (CPUC) Rule 20A. This ordinance specifies that the City will serve as the Lead Agent responsible for coordinating the project with PG&E, AT&T, Comcast, and Wave Broadband (Utilities), leading the design development, and contracting to complete the joint trench construction.
The District boundaries encompass the two-block extent of Antoinette Lane. However, during design development, it became evident that it would be infeasible to complete the southern block before the developer of the 988 El Camino Real housing project completes a major rerouting of underground utilities from within its property. Therefore, the City’s undergrounding project has been separated into two phases to allow the northern block to proceed ahead of the Community and Civic Center Campus construction. The City may schedule the Phase 2 work after the developer’s utility work is complete.
The City engaged Bellecci & Associates, Inc. to prepare the construction plans and specifications. The designer worked closely with PG&E, AT&T, Comcast, and Wave Broadband and the 988 El Camino Real developer to ensure the design will serve all parties. After reviewing the final design, Wave Broadband opted not to place new underground facilities in the Phase 1 project, but still intends to participate in the Phase 2 project. The designer coordinated with the utilities to develop the construction cost allocation, known as the Form B. Rule 20A specifies that the undergrounding costs are allocated among all the parties to the project, i.e., for phase 1 this is PG&E, AT&T, Comcast, and the City. Rule 20A allows the City to invoice the other parties for one-half of their Form B commitments upon the City’s award of the construction contract award and for the remaining amounts upon the City’s acceptance of contract work.
Staff advertised a notice inviting bids for the project on February 26, 2019, and March 5, 2019. On March 26, 2019, staff received four (4) bids in response. The lowest responsive bid was Seton Pacific Construction of San Francisco, California who staff finds to be a responsible bidder. Staff has verified the low bidder’s current contractor’s license with the California State Licensing Board and finds it to be in good standing. In accordance with Public Contracts Code §20166, public works contracts are ordinarily awarded to the lowest responsible bidder whose bid is responsive to the solicitation.
The following is a summary of all bids received:
Base Bid Amount
Seton Pacific Construction of San Francisco, California $2,019,667
Mitchell Engineering of San Francisco, California $2,140,179
Tennyson Electric, Inc. of Livermore, California $2,177,238
St. Francis Electric, LLC of San Leandro, California $2,180,740
The Engineer’s estimate is $ 2,218,122.
The project budget is:
Seton Pacific Construction Contract $2,019,667
Construction Contingency (10%) $ 201,967
Total Project Budget $2,221,634
The construction contingency will be used for any additional costs related to design changes during the construction operations. Costs for these potential change orders will be allocated among the parties in proportion to their benefits.
There are no Disadvantaged Business Enterprise (DBE) requirements for this contract since no federal funds are being utilized on the project. The project is categorically exempt from California Environment Quality Act (CEQA) requirements in accordance with 14 CCR 15302(d) which exempts conversion of overhead electric utility distribution system facilities to underground.
FISCAL IMPACT
In the City of South San Francisco’s Fiscal Year 2018-19 Capital Improvement Program (CIP) Project No. st1702, this project is funded by the general fund, Measure W fund, and the Rule 20A fund. Budget Amendment 19.049 will replace Measure W funds with Infrastructure reserves and appropriate an additional $1 million in Rule 20A funds that are eligible for reimbursement for the project from PG&E Rule 20A allocations for South San Francisco to provide sufficient fund allocation to cover the contract cost.
The Rule 20A fund represents the reimbursement to the City for the utilities’ shares of the costs as defined in the Form B. PG&E will draw its costs from the work credits it has allocated to the City. As of the latest allocation on June 30, 2018, the City has accumulated a balance of a little over $6,780,000 in work credits. The other utilities will pay their cost reimbursements to the City directly from their budgets.
CONCLUSION
Awarding the construction contract to Seton Pacific Construction of San Francisco, California, for the Antoinette Lane Underground Utility District Project, Phase 1 will construct the underground joint trench with conduits, vaults, and boxes such that PG&E, AT&T, Comcast, and will relocate their overhead facilities underground and Wave Broadband will remove its overhead facilities in according with CPUC Rule 20A. Staff recommends that the City Council approve Budget Amendment 19.049, appropriating $1,000,000 in Rule 20A funds and replacing Measure W funding source with Infrastructure Reserves and amending the Fiscal Year 2018-19 Capital Improvement Program.
