This is a technical specification document for a Sedimentation Mixer manufactured by WesTech, submitted in support of the City of Bradenton's Invitation to Bid #26-027NT for the rehabilitation of Sedimentation Basin and Flocculator No. 2 at the Bradenton Water Treatment Plant located at 5600 Natalie Way E, Bradenton, Florida. The procurement requires removal, disassembly, modification, coating, and reinstallation of two existing sedimentation basin mixer systems with new WesTech gearbox assemblies as part of comprehensive basin rehabilitation work. Bids were due April 7, 2026, at 2:30 p.m., with a non-mandatory pre-proposal meeting held on March 20, 2026, at 10:00 a.m. at the project site and a question submission deadline of March 27, 2026, at 5:00 p.m. The construction must achieve substantial completion within 150 calendar days from the Notice to Proceed, with liquidated damages assessed at $500 per calendar day for any delays beyond this timeline.

Bidders must demonstrate relevant experience completing at least two similar projects involving concrete repair and high-performance coatings, with at least one project valued at not less than $500,000 within the past ten years. A 5% bid bond is required for all bids submitted electronically through the OpenGov procurement portal, with performance and payment bonds equal to 100% of the contract amount required for bids of $200,000 or more. Licensed general contractors are eligible to bid with permitted subcontracting up to 50% of the contract price with prior written approval. Contractors must maintain commercial general liability insurance of $1,000,000 per occurrence, workers' compensation insurance at statutory limits, and business auto coverage with the City named as additional insured. While no specific contract value is disclosed, the $500,000 minimum project experience requirement suggests a substantial contract value likely exceeding $1,000,000 based on the comprehensive scope and 150-day construction schedule.
