This is a drawings file supporting Orange County, Florida's sealed Invitation for Bids (Y26-725) for the Orange County Landfill Class I Cell 9-12 Phase 2 Closure project. The project comprises two distinct components: Part A involves regulatory-required landfill closure of portions of Cell 9-12 that have reached design grades, including sequential closure operations, earthwork balancing, installation of 40-mil LLDPE geomembrane, composite drainage net placement, landfill gas transmission piping modifications, and stormwater structure construction (estimated at $44,054,100); Part B addresses electrical and mechanical improvements to the leachate collection system serving Bays 8-13 (valued at $1,519,900). Electronic bids must be submitted through the OpenGov e-Procurement Platform by 4:00 PM EST on Thursday, April 9, 2026, with a question submission deadline of Friday, March 13, 2026 at 4:00 PM EST. A non-mandatory virtual pre-bid meeting is scheduled for February 9, 2026 at 10:00 AM. Work must commence within 14 days of Notice to Proceed, with Substantial Completion required within 670 consecutive calendar days and Final Completion within 730 consecutive calendar days.

Respondents must demonstrate completion of at least three landfill closure projects of 30 acres or more within the past ten years, with at least one project located in Florida, and documented experience with earthwork balancing, geomembrane installation, and leachate collection system work. The combined estimated project value totals approximately $45.6 million, with contract award based on the lowest responsive and responsible bidder subject to Board of County Commissioners approval. A Service Disabled Veteran Business Enterprise (SDVBE) preference applies, offering discounts ranging from 8 percent for bids up to $100,000 down to 3 percent for bids exceeding $5,000,000. All bids exceeding $100,000 require bid bonds equal to at least 10 percent of the total estimated contract amount, with performance and payment bonds equal to the full contract amount required upon award. Mobilization costs are capped at 5 percent of the base bid total, and retainage is set at 5 percent of progress payments for contracts exceeding $200,000. The County will pay for County-imposed permits, licenses, and fees; contractors must obtain all state, federal, and other local agency permits at their own expense. Contractors must coordinate with the County's active landfill gas collection operator, existing operations staff, and regulatory agency inspectors throughout the project duration, including a 12-week maintenance period following substantial completion.
