LOPEZ, CAPITAL PROJECTS DIVISION MANAGER GREG NORBY, DEPUTY GENERAL MANAGER ROGER S. BAILEY, GENERAL MANAGER 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 Environmental Laboratory building (Lab) is located within the Martinez campus and is a critical and specialty facility used every day by staff for permitting, regulatory compliance, and process control. From December 2022 to March of 2023, the Lab roof replacement and building seismic upgrades were completed under the Laboratory Roof and Seismic Upgrades Project. While the floor was identified as requiring replacement due to poor condition caused by a deficient moisture barrier, the roofing and seismic upgrades were completed first to keep the Lab operational during construction, minimize impact on staff, and protect high value and sensitive equipment. The Laboratory Floor Replacement, District Project 100008 (Project) will replace the original flooring built in the early 2000's with an upgraded moisture system to prevent delamination from the concrete August 14, 2023 EOPS Regular Committee Meeting Agenda Packet - Page 8 of 64 Page 2 of 10 subsurface. Attachment 1 shows the project location. The Lab is not expected to be closed during the replacement work. Calpo, Hom and Dong Architects, Inc. (CH&D) prepared the plans and specifications for the Project. The Engineer's estimate for construction is $250,000. This Project was advertised on June 26 and July 1, 2023. Three bids ranging from $246,800 to $275,700 were received and publicly opened on July 21, 2023. The Capital Projects Division conducted a technical and commercial review of the bids and determined that S D M Construction is the lowest responsive and responsible bidder. A summary of bids received is shown in Attachment 2. Central San will administer the construction contract and provide construction management, administration, and submittal review. CH&D will provide technical assistance on an as -needed basis. Upon award, the General Manager will execute the Contract Documents subject to submittal requirements. 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. Approval of this Project will establish the Board's independent finding that this Project is exempt from CEQA. ALTERNATIVES/CONSIDERATIONS An alternative would be to reject all bids. This is not recommended as the reflooring plans have been designed to allow the Lab to remain operational throughout construction and the existing system is deficient. I n time, the flooring could be a safety or tripping hazard as it continues to delaminate. FINANCIAL IMPACTS The total estimated project cost is $389,000 including design, bid price, contingency, construction management, consultant costs, equipment purchase, workspace modifications as detailed in Attachment 3. The replacement work is included in the Fiscal Year 2023-24 District Budget, shown on page 257 with a total budget of $1,450,000 million. To date $1,296,000 million has been spent to complete the roof replacement and building seismic upgrades. As part of the project, Central San will also replace laboratory equipment at the end of its useful life ($50,000). Furthermore, the project will pay for conversion of a copy machine area into two new office spaces using Central San's furniture vendor. Since these project costs will be included, a total of $1,685,000 million will be needed to complete the entire scope for the Lab. A balance of $235,000 is required to fund the Project and will be transferred under the General Manager's delegated authority ($500,000 maximum) in the Capital Improvement Program for individual project budgets. The transfer will be from the Capital I mprovement Budget Contingency account which has adequate funds. COMMITTEE RECOMMENDATION The Engineering and Operations Committee reviewed this matter at its August 14, 2023 meeting and recommended RECOMMENDED BOARD ACTION Staff recommends the following: 1. Find that the Project is exempt from CEQA; and August 14, 2023 EOPS Regular Committee Meeting Agenda Packet - Page 9 of 64 Page 3 of 10 2.
