LOPEZ, CAPITAL PROJECTS DIVISION MANAGER JEAN-MARC PETIT, DIRECTOR OF ENGINEERING AND TECHNICAL SERVICES Roger S. Bailey General Manager ISSUE On February 1, 2018, three bids were received for the construction of the Walnut Creek Sewer Renovations, Phase 12, District Project 8435 (Project). The Board of Directors (Board) must award the contract or reject bids within 50 days of the bid opening. BACKGROUND The Project is part of the ongoing sewer renovation within the Collection System Program of the Capital Improvement Budget (CI B)to replace or rehabilitate deteriorated sewer infrastructure that is in poor condition. This work is coordinated with local jurisdictions, cities, utilities, and private property owners and February 15, 2018 Regular Board Meeting Agenda Packet- Page 15 of 77 Page 2 of 7 tenants. The original Project scope of work included replacement or rehabilitation of approximately 8,500 feet of sewer mains, primarily 6-inch clay sewers, construction of manholes, and other related work within public rights-of-way and easements.An additional 500 feet of sewer replacement was included in the Project based on urgent needs, such as the Ygnacio Valley Road site and other nearby critical sites identified under the Collection System Sewer Renovation - Phase 1, District Project (DP) 8451. The current Project consists of 9,000 feet of sewer replacement using open trench construction, pipe-bursting, and other trenchless methods. The majority of this Project is located within the unincorporated area of Walnut Creek, several sites in the City of Walnut Creek, and one site in unincorporated Alamo, as shown in Attachment 1. Central San staff prepared the plans and specifications for the Project. The Engineer's estimate for construction is $3,200,000. This Project was advertised on January 19 and 24, 2018. Three sealed bids ranging from $3,380,975 to $3,658,455 were received and publicly opened on February 1, 2018. The Engineering and Technical Services Department conducted a technical and commercial review of the bids and determined that California Trenchless, Inc. (CTI) is the lowest responsive and responsible bidder. CTI has worked for Central San in the past and new references were provided with satisfactory feedback. A summary of bids received is shown in Attachment 2. Central San will administer the construction contract and provide construction management, resident engineering, inspection, survey, administration and submittal review. Consultant inspection will be used to supplement staff on an as-needed basis. CEQA: Staff has concluded that this Project is exempt from CEQA under Central San CEQA Guidelines Section 15302, because it involves replacement of existing facilities at substantially 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 it can be seen with certainty that there is no possibility that the activity in question 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 distance involved, and Central San's mitigating construction specifications. These specifications are standardized general and special conditions that are made part of the Project bid documents to address environmental considerations, such as protecting trees and riparian areas, as well as compliance 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. ALTERNATIVES/CONSIDERATIONS Reject all bids, which is not recommended. Delaying or postponing the sewer replacement work is not recommended since several sites have been coordinated with the public and Contra Costa County's upcoming 2018 paving plan. FINANCIAL IMPACTS The total estimated Project cost is $4,550,000, including planning, design, bid price, contingency, construction management, and consultant costs as detailed in Attachment 3. This Project is included in Fiscal Year(FY) 2017-2018 Cl B on page 130 with a total estimated project budget of$4,100,000. The Collection System Sewer Renovation - Phase 1, DP 8451, is on page 142 with an estimated budget of $500,000. The project scopes and budgets will be combined; therefore, a transfer of$450,000 will be completed under the General Manager's delegated authority for the Capital Improvements Program.
