About this file

These documents are construction bid documents for the City of Ann Arbor's Water Treatment Plant (WTP) Flocculation 4/5 Gallery Improvements project, issued on October 7, 2025, with RFP Number 25-48 and Project Number 160804. The project involves improvements to the flocculation basins and gallery, specifically focusing on Flocculation Basins No. 4 and 5, with detailed plans for demolition, piping modifications, and drive system replacements. The bid package includes comprehensive technical drawings covering site layout, demolition plans, process details, and piping configurations, with work areas clearly defined on the site layout and specific components like drive shafts, floor drains, and wall penetrations detailed in the technical drawings.

The project scope includes replacing drive components such as sprockets, chains, bearings, and shafts, installing new drain piping with flexible couplings, and performing necessary concrete wall penetrations. The technical specifications indicate precise requirements for material treatments, such as blasting and recoating cast iron grates, removing corrosion from embedded materials, and installing new pipe supports with specific attachment methods. The drawings are prepared by Fishbeck, an engineering consulting firm located in Grand Rapids, Michigan, and provide extensive technical details to guide the construction and renovation process for the water treatment plant's flocculation gallery.
