About this file

Written by GovTribe AI · Sep 26, 2025

This document is a comprehensive bid set for the City of Oklahoma City Water Utilities Trust, specifically for Filter Pipe Gallery Improvements at the Draper Water Treatment Plant. The project (Project No. WT-0295) involves extensive renovations to the existing filter pipe gallery, including removing and replacing drain pipes, Dresser couplings, concrete pipe supports, pipe support hangers, and concrete flume support hangers. The improvements also include HVAC modifications such as installing new supply and exhaust fans, gas-fired unit heaters, and lighting upgrades. The project will involve coating existing pipes, repairing concrete supports, and upgrading electrical systems, with work to be performed in the Filter Building Pipe Gallery.

The bid documents indicate this is an "Issue for Bid" set, suggesting the project is currently in the procurement phase. The scope encompasses electrical, mechanical, and civil work, with detailed specifications for equipment replacement and system upgrades. While specific budget details are not explicitly stated, the comprehensive nature of the improvements suggests a significant capital investment. The project appears to be funded through the Oklahoma City Water Utilities Trust, with work focused on maintaining and modernizing critical infrastructure at the Draper Water Treatment Plant. The bid set includes extensive technical details, equipment schedules, floor plans, electrical and HVAC diagrams, and specific requirements for demolition, installation, and system integration.
