All designs and engineering services must comply with the following standards: American Society of Civil Engineers (ASCE) guidelines California Code of Regulations (CCR), Title 22 - Environmental Health National Pollutant Discharge Elimination System (NPDES) permit requirements American National Standards Institute (ANSI) specifications Uniform Plumbing Code (UPC) National Fire Protection Association (NFPA) safety guidelines Local and state environmental regulations 2.3 Design Deliverables The project deliverables include: Preliminary Design Report: Drawings, specifications, and cost estimates. Final Design Documents: Detailed engineering plans and technical specifications. Construction Documents: Comprehensive bidding information and contractor instructions. Permitting and Agency Coordination: Required documentation for regulatory compliance. Operation and Maintenance Manual: Detailed guidelines for all newly installed equipment. 3. Service Requirements The selected firm must provide the following services: Site Evaluations: Survey and assess existing conditions. Coordination Meetings: Engage regularly with City staff and stakeholders. Public Outreach: Facilitate meetings and communications as needed. Environmental Compliance: Secure necessary permits and ensure regulatory adherence. Grant Assistance: Support in preparing grant applications, if applicable. Technical Support: Provide expertise and guidance throughout the construction phase. 4. Delivery Requirements Key deadlines and formats for project deliverables are as follows: Submission Formats: All deliverables must be provided in both hard copy and electronic formats. Preliminary Design Report: Due within 8 weeks of contract initiation. Final Design Documents: Due within 16 weeks of Preliminary Design Report approval. Construction Documents: Due no less than 4 weeks before construction commencement. Progress Reports: Provided bi-weekly, detailing completed tasks and upcoming milestones. 5. Conclusion This Scope of Work outlines the requirements for the Headworks and Influent Metering Improvements Project. The City of Lompoc seeks proposals from qualified firms capable of delivering superior services that align with the outlined specifications. All submissions should demonstrate expertise, attention to detail, and commitment to delivering high-quality results. 3.2. Major Tasks 1.1 Influent Meter Improvements Review the condition of existing influent metering systems. Evaluate two potential options: Improve influent flow monitoring and sampling along Floradale Avenue. Install a new metering station closer to or within the plant Headworks. 1.2 Headworks Improvements Replace influent sluice gate and actuator, ensuring proper seating and sealing functionality. Install three new bar screens (2 active + 1 redundancy). Replace the interior traveling bridge crane and crane system to allow access to hatch screening debris bins or equipment. Rehabilitate concrete influent channels for manual stop gates, enabling bar screen isolation. Apply polyurethane coatings to influent channels and install channel covers (instead of grating) to minimize odors. Develop a bypass pumping plan for continuous influent screening during headworks construction. Design an odor control system (for hydrogen sulfide) to capture air from covered channels and stage the odor control unit outside adjacent to the Headworks building. Improve the flow monitoring equipment for better accuracy and replace existing clamp-on meters downstream of the pump station. Install a new pH meter downstream of bar screens to prevent sampling ragging or fouling. Evaluate the current building facilities' condition and location, proposing recommendations for renovation or new construction. Items to address include: Remove and replace the built-up roof system. Fully replace the building air handling system (supply and exhaust) to maintain active air exchange and reduce hydrogen sulfide odors. Patch stucco, replace doors, and paint the building's interior and exterior. Recommend a non-slip concrete flooring coating for both levels to reduce fall risks. 2. Deliverables 2.1 Project Schedule Submit an initial project schedule, estimating timelines for influent metering and building assessment reports (90 days), as well as design durations for the influent metering, building improvements, and headworks upgrades. 2.2 Reports Evaluation of Influent Metering Alternatives: Evaluate whether to upgrade existing meters or relocate metering structures closer to the wastewater plant. Building Condition Assessment: Analyze the current condition and recommend improvements. 2.3 Final Report Incorporate all feedback for the influent metering alternatives and condition assessment into a final report with recommendations. Address comments provided by City of Lompoc management and staff. 2.4 Design Deliverables Preliminary Design Report: Provide a letter summarizing design features, including: Influent metering Building improvements Headworks upgrades (sluice gate replacement, channel improvements, bar screens, odor treatment) 30% Design Submittal: Include preliminary drawings, equipment specifications, and cost estimates. 60% Design Submittal: Incorporate feedback from the 30% review and provide updated drawings, specifications, and construction cost estimates. 90% Design Submittal: Incorporate feedback from the 60% review and provide nearly final design drawings, specifications, and cost estimates. Final Design Submittal: Address feedback from the 90% review and provide complete design drawings and specifications. 3. Submittal Format Documents: All deliverables must be submitted in hard copy and Adobe PDF formats. Drawings: Include CAD files (latest version). Letters, Studies, and Reports: Submit in MS Word format. Cost Estimates: Provide in MS Excel format. 4. Ownership of Work The City shall own all work produced for this project. The consultant must provide all deliverables upon request. The City will supply any available CAD files, GIS background files, or aerial photos. However, the consultant is responsible for verifying the accuracy and completeness of all information. Schedule Following City Council authorization, the City of Lompoc will enter into an agreement with the successful Consultant. This authorization is anticipated to occur after proposal submissions. After a written Notice to Proceed is issued by the City, the Consultant's work shall commence within 30 days. The Notice to Proceed will specify: The work to be completed. A schedule for completing the work. The Consultant shall prepare a Project Delivery Schedule aligned with the overall project timeline. This schedule must clearly identify the duration, beginning dates, and completion dates for all significant tasks. The schedule should be structured based on the tasks outlined in the resource allocation matrix included in this Request for Proposal. Documentation The Consultant must: Furnish the City with original certificates and amendatory endorsements for all required coverages. Ensure all certificates and endorsements are approved by the City before beginning Consulting Services. Provide certified copies of policies upon the City's request.
