CDr EENI RAL SAN BOARD OF •' �J POSITION PAPER CENTRAL CONTRA COSTA SANITARY DISTRICT � � • MEETING DATE: MAY8, 2023 SUBJECT: REVIEW DRAFT POSITION PAPER TO AWARD A CONSTRUCTION CONTRACT IN THE AMOUNT OF $5,888,730 TO DEVANEY ENGINEERING, INC., THE LOWEST RESPONSIVE AND RESPONSIBLE BIDDER FOR THE PLEASANT HILL SEWER RENOVATIONS, PHASE 2, DISTRICT PROJECT 5991; AND FIND THAT THE PROJECT IS EXEMPT FROM THE CALIFORNIA ENVIRONMENTAL QUALITYACT (CEQA) SUBMITTED BY: INITIATING DEPARTMENT: JASON FITCH, ASSOCIATE ENGINEER ENGINEERING AND TECHNICAL SERVICES - CAPITAL PROJECTS REVIEWED BY: SASHA MESTETSKY, SENIOR ENGINEER EDGAR J. LOPEZ, PROVISIONAL 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. Authorization is also required for the General Manager to execute the Contract Documents subject to submittal requirements. BACKGROUND The Pleasant Hill Sewer Renovations, Phase 2, District Project 5991 (Project) is part of the ongoing sewer renovation within the Capital Improvement Budget (CI B) and Collection System Program aimed to replace or rehabilitate deteriorated sewer infrastructure that is at the end of its useful life and in poor condition. The Project has been coordinated with other improvements being completed by the Contra Costa Water District and the City of Pleasant Hill's paving plans, as well as other utilities, businesses, private property owners, and tenants. This Project will replace or rehabilitate approximately 8,700 feet of small diameter sewers, maintenance access structures, and other related sewer 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, horizontal directional drilling, pilot tube guided boring, and cured -in -place pipe rehabilitation. An overview map of all site locations is shown in Attachment 1. May 8, 2023 EOPS Regular Committee Meeting Agenda Packet - Page 11 of 25 Page 2 of 10 The Engineer's estimate for construction is $4,700,000. This Project was advertised on April 10 and April 17, 2023. Five sealed bids ranging from $5,888,730 to $6,788,000 were received and publicly opened on April 27, 2023. The Capital Projects Division conducted a technical and commercial review of the bids and determined that Devaney Engineering, Inc. is the lowest responsive and responsible bidder with a total bid amount of $5,888,730. 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 inspection will be performed by one of Central 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 Central San staff has coordinated the Project with the City of Pleasant Hill, Contra Costa Water District, private property owners, businesses, nearby residents, and utilities. Delaying or postponing the sewer work is not recommended. The public sewers are in need of replacement and due to the City's paving plans, the proposed timeline is recommended by staff. The planning effort for this Project has been in the Cl B for several years and has been difficult to coordinate due to the below industry standards for the existing utilities and paving in the neighborhood. Performing this work along with the other agencies is cost effective for all parties and reduces public impacts to the residents. FINANCIAL IMPACTS The total estimated project cost is $7,958,000 which includes planning, design, bid price, additive bid items, contingency, construction management, and consultant costs as detailed in Attachment 3. This Project is included on page 203 of Central San's Fiscal Year 2022-2023 Budget, and the construction will be funded by the Collection System Sewer Renovation, Phase 2 on page 225. There is adequate funding for the Project. Staff is recommending a 10 percent contingency on this Project since additional work may be added to urgently repair or replace nearby sewers and to cover any expenses due to unknown conditions and changes associated with renovation work. May 8, 2023 EOPS Regular Committee Meeting Agenda Packet - Page 12 of 25 Page 3 of 10 COMMUNITY OUTREACH Central San staff did extensive homeowner outreach to prepare residents for the upcoming construction work. Initial project letters were sent in the Fall of 2022 informing residents of the design work. Throughout the course of design, staff addressed email and phone inquiries regarding the Project and conducted in - person outreach with several easement homeowners. The public was also invited to a public workshop that was held at the Pleasant Hill Senior Center on April 5, 2023 to address any questions or concerns regarding the Project. Additionally, the public was encouraged to reach out with any additional questions or concerns they may have. To date, all questions and concerns received have been answered and addressed. COMMITTEE RECOMMENDATION The Engineering and Operations Committee reviewed this matter at its meeting on May 8, 2023, and recommended RECOMMENDED BOARD ACTION Staff recommends the following: 1. Find that the Project is exempt from CEQA; 2. Award a construction contract in the amount of $5,888,730 to Devaney Engineering, Inc., the lowest responsive and responsible bidder, for the construction of the Pleasant Hill Sewer Renovations, Phase 2, District Project 5991; and 3.

This project has deeper excavations and added complexity compared to previous projects. Engineer's estimate is $400. Devaney Engineering, Ines bid is $540 and average of all bidders is $580. 35% increase from Engineer's estimate is also due to higher costs of materials and labor, and inflation over the past few years.
