Granville Health System

Request for Information (RFI)

Deaerator (DA) Tank Replacement - Central Energy Plant

1. Purpose

Granville Health System is issuing this Request for Information (RFI) to qualified mechanical contractors, boiler system specialists, and engineering firms regarding the replacement of the existing Deaerator (DA) tank system serving the hospital's central energy plant.

Objectives of this RFI include:

Coordinate on-site vendor assessments with GHS representatives

Obtain engineering recommendations for replacement of the existing DA tank system

Understand installation requirements, phasing impacts, and operational considerations

Gather budgetary pricing to support immediate replacement.

This RFI is for planning and information only. No award will be made solely from this request.

2. Project Scope

Granville Health System intends to replace the existing DA tank, including evaluation and coordination with the current boiler plant.

Scope may include:

Replacement of existing Deaerator (DA) tank

Evaluation and replacement of feedwater pumps (if required)

Associated piping, valves, and controls

Integration with existing boiler systems (two main boilers)

Electrical and control system upgrades (as needed)

Structural support, pad, or rigging considerations

Insulation and system commissioning

The DA Tank currently supports a closed-loop boiler feedwater system serving the hospital campus and returning to the central energy plant.
