NE WRF Influent Building Floor Repair

The City of Clearwater, Florida is requesting bids on demolition and replacement of grating systems at the Northeast Water Reclamation Facility's influent building under IFB 25-0004-UT, with bids due August 27, 2026.

The scope includes demolition of existing grating over channels in the influent headworks building through the splitter box and installation of new grating with associated structural supports. Work encompasses five primary phases: grating replacement at the influent box, mechanical screen influent channels, grit vortex system influent channels, odor control system flanges and piping, and covered fiberglass reinforced plastic (FRP) grating and aluminum beams between the influent building and splitter box. The contractor must field-verify all existing conditions, as not all conditions are captured in the drawings, and an engineer's site visit will identify specific members requiring replacement. The facility must remain in continuous operation during construction; the contractor is responsible for temporary utilities, pumping, and coordination with plant maintenance activities. The contract duration is 365 days.

The bid structure comprises twelve base lump-sum line items covering mobilization, demolition and disposal, 316 stainless steel structural framing, plank FRP grating, aluminum access hatches, molded FRP grating, miscellaneous aluminum framing, aluminum railings, and odor control modifications, plus unit-price items for epoxy coating and concrete repairs. Three additive alternates address downstream channel work. All materials must be new and unused from reputable manufacturers. The contractor must submit a Construction Phasing Plan and Maintenance of Plant Operations Plan prior to commencing work, obtain all required permits, provide insurance and bonds, and furnish a color video of existing site conditions. A one-year warranty period commences upon substantial completion. Payment is monthly based on percentage of completion for lump-sum items and per unit for measured items, with mobilization disbursed incrementally as work progresses. The contractor bears all costs for water usage, temporary facilities, equipment relocation, weather protection, and restoration of damaged adjacent property.
