The Florida Keys Aqueduct Authority is soliciting electronic bids through e-Builder for the Marathon Highway Crossing Improvements, Phase I project in Monroe County, Florida, with bids due November 19, 2026 at 2:00 p.m. local time. The mandatory prebid meeting was scheduled for October 28, 2026 at 2:00 p.m. via Microsoft Teams. No set-aside or local-vendor preference applies. The authority encourages Minority and Women Business Enterprise subcontracting but does not establish a formal set-aside, and the contractor must self-perform at least 60 percent of the total work value.

The scope covers furnishing all labor, materials, equipment, and incidentals to install approximately 270 linear feet of new 8-inch, 6-inch, and 2-inch underground watermains. Materials include C-900 PVC, DR-11 HDPE, and Schedule 80 PVC with ductile iron fittings and appurtenances. Work also includes tapping sleeves, gate valves, connections to existing 6-inch and 12-inch watermains, testing and commissioning, temporary traffic control, environmental protection, tree protection and replacement, and full restoration of disturbed areas. Drawings and specifications are available through Demand Star, the authority's website, or e-Builder's Bid Portal.

The source does not name a contract value. Substantial completion is required within 120 calendar days of the Notice to Proceed, with final completion 30 calendar days later, and construction must begin within ten calendar days of that notice. Liquidated damages are $1,000.00 per calendar day for missing substantial completion. Bidders must submit 5 percent bid security by certified check, cashier's check, or bid bond. For contracts exceeding $200,000, separate performance and payment bonds equal to 100 percent of the contract price are required. Contracts of $200,000 or less may follow alternative bonding procedures involving retainage.
