Turbo Blower No. 6

The City of Bend invites Sealed Bids for the Turbo Blower No. 6 Project, Project No. 1SW01. The project consists of furnishing, installing, and commissioning a sixth 400-horsepower dual-core APG-Neuros turbo blower in Blower Building 32B at the Bend Water Reclamation Facility. The building was originally constructed with space reserved for a sixth turbo blower as part of a planned future expansion.

The installation of a sixth turbo blower will utilize the space originally reserved for future expansion and will provide additional aeration capacity and operational redundancy to support current and projected treatment needs.

Bend City Council approved an exemption to expressly specify and require the Contractor to procure and supply an APG-Neuros brand turbo blower for this Project on October 7, 2026, pursuant to Oregon Revised Statutes 279C.345.

The Engineer's estimate is **$914,000 to $1,059,000**.

Work associated with this installation includes relocating the adjacent air handling tank and associated piping and utilities, as necessary, to provide adequate space, access, and operational clearances for the new equipment. Structural improvements include the design and construction of a reinforced concrete equipment pad to support the turbo blower and accommodate operational and maintenance loads.

Mechanical work includes installation of all process piping, supports, fittings, valves, and appurtenances required to integrate the new turbo blower into the existing aeration system. Electrical work includes all required electrical studies, power distribution equipment, conduit, wiring, disconnects, grounding, and control wiring necessary for a complete and operational installation.

The Contractor shall furnish and install all field wiring and communications infrastructure required for blower monitoring and control. Programming, PLC integration, SCADA modifications, and associated control system configuration will be performed by the City.

The Project also includes all associated modifications, testing, startup, and commissioning activities necessary to deliver a complete, fully functional, and reliable blower installation.
