RFI : Deaerator (DA) Tank Replacement

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.

3. Requested Information

3.1 System Recommendations

• Tank construction materials and expected lifespan

• Redundancy considerations for healthcare environments

• Recommended deaerator configuration

• Guaranteed oxygen removal performance (ppb)

• Operating pressure and temperature ranges

• Storage Volume and effective hold time

• Turndown capability

• Materials and Construction of proposed DA Tank

• Controls and Instrumentation

3.2 Compliance & System Standards

• ASME Boiler and Pressure Vessel Code compliance

• National Board Inspection Code (NBIC) considerations

• Applicable state and local boiler/mechanical codes

• OSHA requirements for installation and operation

3.3 System Interface & Utility Requirements

• Steam and condensate return integration requirements

• Water quality considerations and chemical treatment coordination

• Venting and exhaust requirements

• Blowdown and drainage requirements

• Electrical service requirements

• Control system integration with existing plant systems

3.4 Installation Requirements

• Expected construction duration

• Phasing requirements to maintain boiler operation

• Rigging and access constraints within existing energy plant

• Measures for safety, noise control, and operational continuity

3.5 Service & Long-Term Maintenance

• Warranty periods and coverage levels

• Recommended preventative maintenance (PM) programs

• Spare parts availability and lead times

• Expected lifecycle of system components

3.6 Budgetary Information

Provide rough order-of-magnitude pricing for:

• Engineering and design fees

• DA tank equipment

• Pumps, controls, and accessories

• Installation labor

• Piping and mechanical modifications

• Electrical and controls integration

• Temporary system provisions (if required)

• Commissioning and startup

All pricing should be structured to support immediate replacement.

4. Vendor Site Visits

• Review of existing DA tank and boiler plant

• Inspection of feedwater, condensate return, and piping systems

• Evaluation of mechanical room layout and access

• Identification of rigging and installation constraints

• Assessment of phasing limitations and operational risks

Target Date for completed initial site visits: 5/1/2026

Contacts for coordination: Zeb Barnette, Jonathan Pernell

5. Response Format

• Company information and primary contacts

• Relevant experience with boiler plant / DA tank systems (healthcare preferred)

• Credentials, licensing, and mechanical/engineering capabilities

• Recommended system approach and configuration

• Technical literature or product data sheets

• Lead times for equipment and mobilization

• Installation approach and phasing plan

• Maintenance and service offerings

• Preferred site visit dates

• Budgetary pricing (design, labor, equipment, etc.)
