DISCUSSION The Lift Station 7 and Lift Station 8 Ventilation and Lighting Improvements Project will address the necessary repairs to the ventilation and lighting systems at the two stations that have exceeded their design life. The project includes the removal and replacement of all the existing ventilation equipment and upgrading the equipment to current standards, including new ducting, fans and control panels. The systems will be connected to the City's existing SCADA system to allow for remote monitoring. The lighting systems within the station wet wells will be replaced, and various other non- functioning light fixtures will also be replaced throughout the remainder of both stations. Additionally, the air monitoring systems that screen for hazardous gases and oxygen levels withing the station that are required to allow personnel access will be replaced. Bids Sealed bids for this project were opened on February 9, 2021. A total of three bids were received, ranging from $1,020,000 to $1,536,000. The lowest bid was submitted by WestCal Design and Build, Inc. of Union City, California, in the amount of$1,020,000 (see Attachment 2 for the bid summary). This is approximately 7 percent lower than the Engineer's Estimate of$1.1 million. The bid documents were found to be in order and past work performed by WestCal was verified to be satisfactory. Staff recommends award of the construction contract to WestCal Design and Build, Inc. for $1,020,000. Consultant Services The project designer, TJC and Associates, Inc., will be providing construction support services to review shop drawings, responses to requests for information, and periodic inspections. TJCAA's mechanical subcontractor, Schaaf and Wheeler, will review the mechanical components of the project and provide site inspections. See Attachment 3 for the professional services agreement and scope of work with TJCAA. Under another existing on-call contract with the City, Tesco Controls, Inc. will be providing SCADA control integration between the new ventilation systems and the existing SCADA system, which is used to operate the City's sewer system. The work shall include updates to SCADA control panels, field work and software programming. Budget The project was identified to be completed as part of the Repair and Replacement Program and no project or funding was identified in the Capital Improvement Program. After the completion of the 30 percent design, the project cost far exceeded original expectations and it was determined that the project needed to be publicly bid as a Capital Improvement Project. The anticipated total expenditure for this project is $1,332,937, including a construction contingency of$153,000 and $87,350 in construction support services (to be provided by various consultants as outlined), leaving a project shortfall of$1,260,350 (see Attachment 1). Staff recommends the allocation of$1,260,350 from the Sewer Replacement Fund (Fund 431). The funding and anticipated project expenditures are further detailed in Attachment 1. Page 3of4
