This is a Design Report Chapter document supporting the City of Lompoc's solicitation for the Headworks and Influent Meter Improvements Project at its Regional Wastewater Reclamation Plant in Santa Barbara County, California. The project encompasses comprehensive design and engineering services for critical wastewater treatment infrastructure upgrades, including replacement of the 1974 influent gate and actuator, installation of three new bar screens, rehabilitation of concrete influent channels, development of a bypass pumping plan, and implementation of an odor control system. The scope of work requires the selected engineering consultant to perform detailed facility assessments, conduct hydraulic modeling, develop facility layout designs, specify equipment, and create integration plans. Deliverables include preliminary and final design documents, construction documents, and an operation and maintenance manual. A mandatory pre-bid job walk is scheduled for May 14, 2025, with proposals due by June 30, 2025, at 3:00 pm. All proposals will remain valid for 90 calendar days after the bid opening. The City will award the contract to the most responsive and responsible bidder based on comprehensive evaluation of technical capabilities and proposed approach.

Compensation will be based on approved actual time and materials, not to exceed an agreed-upon "Not-to-Exceed Fee," with progress-based payments contingent on task completion. The selected consultant must maintain $1,000,000 in Errors and Omissions Professional Insurance, along with general liability, automobile liability, and worker's compensation coverage. Previous master planning efforts, including a 2002 master plan by Kennedy/Jenks Consultants and a 2005 design report by Brown and Caldwell, identified the infrastructure upgrade needs at this facility. While specific budget details are not definitively stated in the procurement, previous design reports estimated total project costs ranging from approximately $300,000 to over $41 million for various plant improvement scenarios. The facility currently serves approximately 9,000 sewer connections with an Average Dry Weather Flow capacity of 5.0 MGD. The contract represents part of a phased modernization approach for the Regional Water Reclamation Plant. No explicit set-aside designations for disadvantaged enterprises are specified in the procurement.
