CITY COUNCIL REGULAR MEETING AGENDA PACKET

Page 2 of 3 No. 24278. On December 19, 2023, City Council increased the authorization for change orders and the project’s contingency by $100,000 to a total of $182,000. This increased authorization was required due to changes in the work at Meadowlark Park caused by unanticipated field conditions. Construction began in October 2023 and was completed in May 2024. DISCUSSION As part of the annual sewer maintenance program to address sewer lines and structures needing replacement or rehabilitation, this project removed and replaced 572 linear feet of 8- inch sewer line and 269 linear feet of 10-inch sewer line, installed 329 linear feet of 18-inch sewer line, replaced 69 linear feet of sewer laterals, installed four sewer manholes, and reconstructed three manhole inverts. The project also removed one sewer manhole, 12 linear feet of 6-inch sewer line, and 215 linear of 18-inch sewer line, abandoned 1,142 linear feet of 8-inch sewer line, and modified sewer manholes along Rose Avenue to divert sewer flows from the current west-to-east system to an existing system to run east-to-west. During the construction of the project, the City’s on-call materials testing firm, Geocon Consultants, Inc., provided materials testing and inspection services for $3,432. The City’s archeological consultant, Alta Archaeological Consulting, LLC (Alta) provided monitoring services within project areas where there was a potential to encounter cultural resources. The project required additional services from Alta beyond the original contract amount due to extended limits of excavation after uncovering unmarked dry utilities requiring additional trenching, which increased the new total anticipated amount to $24,345. All work performed by Golden State Construction & Utility, Inc. has been reviewed and verified by the City Engineer to meet the City’s approved plans and specifications and has been completed to the satisfaction of the Director of Public Works. Staff recommends the City Council accept the work, authorize the City Clerk to file a Notice of Completion, authorize the release of retention 30 days after recordation, and approve the contract amendment with Alta Archaeological Consulting LLC. The contract with Alta will be closed out after the contract amendment has been processed. EQUITY AND SUSTAINABILITY Staff followed the City Procurement Policy for purchasing procedures as these types of repairs are routine matters of City business. OUTREACH Construction notices were sent to residents and businesses adjacent to project locations.
