LOPEZ, CAPITAL PROJECTS DIVISION MANAGER JEAN-MARC PETIT, DIRECTOR OF ENGINEERING AND TECHNICAL SERVICES Roger S. Bailey General Manager ISSUE The Board must award the contract or reject bids within 50 days of the bid opening.Authorization is required for the General Manager to execute the Contract Documents subject to submittal requirements and include up to a 15-percent contingency. Board authorization is also required to execute an amendment to a professional engineering services agreement for an amount greater than $200,000. BACKGROUND The Emergency Sludge Loadout Facility(ESLF)is located within the wastewater treatment plant in Martinez and is used for emergency storage and truck loading of dewatered sludge in case the incinerators are unavailable.The ESLF Upgrades, District Project(DP)7348A(ESLF Project)will install new isolation and modulating gates on the sludge silos, make improvements to other mechanical and controls systems, and upgrade the odor control and ventilation systems.The work under this project will increase operational reliability and flexibility for emergency solids handling.A map showing the location of the ESLF Project is included as Attachment 1. The ESLF Project is the first of three construction contracts as part of the Solids Handling Facility Improvements, DP 7348 (Solids Project).These three separate contracts include the ESLF Project, the Sludge Blending Tank Repairs, DP 6172, and the Solids Project.The Sludge Blending Tank Repairs and ESLF Project are being constructed ahead of the Solids Project to ensure that the sludge bending tank and ESLF is fully functional and available for use during the construction of the Solids Project, which is scheduled to begin around June of 2020. The Engineer's estimate for construction of the ESLF Project was$2,300,000.This project was advertised on April 26 and May 1, 2019.Three sealed bids were received and publicly opened on May 30, 2019.The Engineering Department conducted a technical and commercial review of the bids and determined that Auburn Constructors, LLC is the lowest responsive and responsible bidder with a total bid amount of$2,150,300.A summary of bids received is shown in Attachment 2. Black&Veatch Corporation (B&V)designed the ESLF Project as part of the larger Solids Project design effort. Staff recommends amending the existing professional engineering services agreement with B&V to include design engineering support services during the construction phase.The additional engineering services will include submittal review and design response services,field verification, and asset management record documentation.A$220,000 cost ceiling has been negotiated with B&V to provide these services, which includes a cost of$45,000 to update the record drawings and asset information for the entire facility.The asset and drawing documentation will be incorporated in the Cityworks and GeoPortal systems(online database access for staff). Central San staff will administer the construction contract and provide contract management and administration. Construction inspection will be done by one of Central San's existing consultant inspection services agreements. In addition, staff will be coordinating and managing the solids disposal under a separate contract with Lystek International Inc. (Lystek)as a pilot effort during the commission of the ESLF Project. Lystek is a organic materials and recovery firm with experience working with wastewater municipalities for solids waste process management in an environmentally safe manner and located at the Fairfield Suisun Sewer District. CEQA Staff has concluded that this project is exempt from CEQA under Central San's CEQA Guidelines Section 15301, since it involves minor alterations to existing public facilities involving no expansion of use, and CEQA Guidelines Section 15302, since it involves replacement of existing public facilities at the same location and with the same purpose.Approval of this project will establish the Board's independent finding that this project is exempt from CEQA. ALTERNATIVES/CONSIDERATIONS The Solids Project is a two to three year construction effort and highly complex. Several critical equipment and processes will be offline and coordinated for the construction of replacement systems including, but not limited to, the incinerator controls, air pollution control equipment, dewatering equipment, and new electrical and controls infrastructure in the Solids Conditioning Building. Staff recommends upgrading the ESLF before commencing the Solids Project to provide a loading system that can be used more on a daily basis in case of issues that could arise during the Solids Project. The Board may elect to reject all bids and provide another alternative. FINANCIAL IMPACTS The total estimated costs for constructing this project is$3,548,000,which includes planning, design, construction contract, contingency, and construction management costs as shown in Attachment 3. The ESLF Project is being funded by the Solids Project under a sub-account,which has adequate budget for the ESLF Project construction phase. No transfer of funds will be required.The Solids Project is listed under the Fiscal Year(FY)2019-20 Budget on page 182 with a FY 2019-20 project budget of$6,550,000. COMMITTEE RECOMMENDATION The Engineering and Operations Committee reviewed this matter at the June 4, 2019 meeting 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$2,150,300 for the construction of the Emergency Sludge Loadout Facility Upgrades, District Project 7348A,to Auburn Constructors, LLC, the lowest responsive bidder; 3.Authorize the General Manager to amend the existing professional engineering services agreement with Black&Veatch Corporation to include construction services in the amount of$220,000; and 4.Authorize the General Manager to execute the Contract Documents subject to submittal requirements and include up to a 15- percent contingency.
