LOPEZ, CAPITAL PROJECTS DIVISION MANAGER JEAN-MARC PETIT, DIRECTOR OF ENGINEERING AND TECHNICAL SERVICES ISSUE The Board of Directors (Board) must award the contract or reject bids within 50 days of the bid opening. The General Manager also needs authorization to execute the Contract Documents subject to submittal requirements including up to a 15-percent contingency. BACKGROUND The Walnut Creek Sewer Renovations, Phase 15, District Project 8465 (Project) is part of the Collection System Program of the Capital Improvement Budget (Cl B). Its aim is to replace or rehabilitate deteriorated sewer infrastructure at the end of its useful life and in poor condition. The construction work is coordinated with local jurisdictions, cities, utilities, private property owners, and tenants. I n the midst of the novel coronavirus (COVI D-19), Central San continues construction activities as an essential service and infrastructure provider under guidelines provided by Contra Costa Health Services, Occupational Safety and Health Administration, state and federal agencies. Several sites in this Project include work on private properties and public rights-of-way. The construction contract includes strict provisions to mitigate the spread of COVID-19, such as personal protective equipment, handwashing June 1, 2021 EOPS Regular Committee Meeting Agenda Packet- Page 3 of 10 Page 2 of 6 stations, and other safety items, practices, and procedures as guidelines stricken or lessen. The Project will replace or rehabilitate approximately 9,300 feet of small 6-to 8-inch diameter sewer mains, utility access holes, and other work within public rights-of-way and private easements. Central San staff prepared the plans and specifications for the Project. Construction methods primarily include open trench, pipe bursting, and cured-in-place pipe. Attachment 1 provides an overview map of all the site locations. The Engineer's estimate for construction was $4,000,000. Central San advertised this Project on May 4 and 11, 2021. Central San received seven bids ranging from $3,117,488 to $4,698,191 and publicly opened them on May 25, 2021. The Capital Projects Division conducted a technical and commercial review of the bids and determined that Basset Engineering (Basset) is the lowest responsive and responsible bidder with a total bid amount of$3,117,488. Basset is a new general contractor to Central San, and references were provided and verified by staff. Basset has completed similar work in the San Francisco BayArea and is listed as a pre-qualified sewer contractor for the San Francisco Public Utility District. Attachment 2 supplies a summary of the bids received. Central San will administer the construction contract and provide construction management, resident engineering, survey, administration, and submittal review. Central San has engaged a consultant under an existing agreement to provide inspection services. CEQA Staff has concluded that this Project is exempt from CEQA under Central San CEQA Guidelines Section 15302. It involves the replacement of existing facilities at the same locations and with the same purpose and level of activity as the facilities being replaced.Any capacity increases are for non-growth inducing, wet weather purposes. The Project also is exempt under Central San CEQA Guidelines Section 15061(b)(3), since there is no possibility that the Project may have a significant effect on the environment. This certainty is based on Central San's experience with numerous sewer construction projects of this nature, the relatively short distances involved, and Central San's mitigating construction specifications. These specifications are standardized general and special conditions in the Project bid documents to address environmental considerations, such as protecting trees and riparian areas. They comply with applicable federal, state, county, district, municipal and local laws, ordinances, orders, and regulations. Approval of this Project will establish the Board's independent finding that this Project is exempt from CEQA. ALT ERNAT IVES/CONSIDERAT IONS 1. Delay or postpone the work. Staff has coordinated the Project with private property owners, the public, utilities and cities, and does not recommend this option. 2. Reject all bids. Staff does not recommend this either. FINANCIAL IMPACTS The total estimated Project cost is $4.68 million. The cost includes planning, design, bid price, contingency, construction management, and consultant costs as detailed in Attachment 3. The Project budget is also shown on page 219 of Central San's Fiscal Year 2021-22 Budget at$5.4 million. Staff recommends a 15-percent contract contingency on this Project. The contingency would cover additional urgently needed repairs or replacement of nearby sewers and the risks associated with renovation work. Presently, staff does not foresee any added budgetary impact on this Project due to COVI D-19.

I nitial Project letters were sent in the summer of 2020 informing residents of the design work. Throughout the course of design, staff addressed email and phone inquiries about the Project and conducted face-to-face outreach with several easement homeowners. Due to COVI D-19, staff was creative in preparing residents for construction. In place of a public meeting, staff supplied a video presentation on the Central San website.Additionally, the public was encouraged to reach out with any other questions or concerns. To date, all questions and concerns received have been answered and addressed.
