LOPEZ, CAPITAL PROJECTS DIVISION MANAGER JEAN-MARC PETIT, DIRECTOR OF ENGINEERING AND TECHNICAL SERVICES Roger S. Bailey General Manager ISSUE On March 8, 2018, three bids were received for the construction of the Lafayette Sewer Renovations, Phase 12, District Project 8446 (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 April 5, 2018 Regular Board Meeting Agenda Packet- Page 80 of 164 Page 2 of 6 tenants. The Project consists of 8,800 feet of sewer replacement using open trench construction, pipe-bursting, and other trenchless methods. The majority of this Project is located within the City of Lafayette and several sites in the Town of Moraga, 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 February 22 and 27, 2018. Three sealed bids ranging from $2,742,234 to $3,288,000 were received and publicly opened on March 8, 2018. The Engineering and Technical Services Department conducted a technical and commercial review of the bids and determined that Precision Engineering, Inc. (Precision) is the lowest responsive and responsible bidder. References were provided for Precision and staff received 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, survey, administration and submittal review. Consultant survey will be used to supplement staff on an as-needed basis. Construction inspection will be performed by one of Central's San's consultant inspection service contracts. 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 Delaying or postponing the sewer replacement work is not recommended since several sites have been coordinated with the public, the City of Lafayette's upcoming paving plan, and sites based on the Riverwatch agreement. Another alternative would be to reject all bids, which is not recommended. FINANCIAL IMPACTS The total estimated Project cost is $4,033,600, 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 139 with a total estimated project budget of$4,111,000.
