Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the solicitation for pump replacement and repair services.

• Pumping Solution: The chilled water solution is City of Ames water with a corrosion inhibitor, not a glycol solution.
• Timeframes: The timeframes specified in the Statement of Work are expected. Contractors may explain reasons for inability to meet timeframes for Contracting Officer consideration.
• Inertia Pad: The existing inertia pads are 4" concrete housekeeping pads with steel frames and are to be reused. Steel pump skid bases are tack welded to the inertia pad frame and bolted into the concrete pad.
• Pump/Motor Brand: The new pump and motor for #2 may be a different brand, provided it meets the same pumping specifications and performance as existing pumps in a horizontal skid configuration.
• Alternative Pump Option: An add option will be included for three new motors and pumps on skids with specifications and performance matching existing pumps in a horizontal configuration. These do not need to be the same manufacturer.
• Pump Configuration: Only horizontal split-case pump and motor assemblies will be considered.
• Past Performer: Hutcheson Engineering has performed pump repairs for the facility in the past.

These clarifications provide specific details on materials, equipment, and configuration requirements, which may impact proposal preparation and pricing. The potential for an add option for three new pumps/motors is also noted.
