STATEMENT OF WORK (SOW)

Tankless Water Heaters Quarters 1 and Quarters 2

(Asset No. 10014643)

Nathaniel P. Reed Hobe Sound National Wildlife Refuge

Hobe Sound, Florida

Type of Service/Construction (NAICS): 238220 (Plumbing, Heating, and Air-Conditioning Contractors) PR Number: ______________________

Project Title: Quarters Water Heater Replacement and Conversion (Tankless)

1. General

1.1 Description. The U.S. Fish and Wildlife Service (USFWS), Nathaniel P. Reed Hobe Sound National Wildlife Refuge (Hobe Sound NWR), requires replacement of aging domestic hot water systems serving Quarters 1 and Quarters 2 on refuge property. The current water heaters are located in attic spaces and are beyond recommended replacement age.

1.2 Purpose/End Application. Provide safe, reliable, code-compliant domestic hot water service to Quarters 1 and Quarters 2 by replacing existing tank-type water heaters with tankless water heating systems (electric, unless otherwise approved), including any associated plumbing modifications and (as applicable) electrical panel/breaker work. The desired outcome is a functional system that meets household demand and reduces the risk of attic flooding through proper installation, secondary containment/drainage, and commissioning.

1.3 Contractor Qualifications. Contractor shall be a State of Florida licensed plumbing contractor and shall use properly licensed and supervised personnel. If electrical work is included, electrical work shall be performed by a State of Florida licensed electrical contractor (prime or subcontractor). Contractor shall demonstrate experience installing and commissioning residential tankless water heating systems and performing work in occupied residences.

1.4 Pre-Proposal Site Visit. A site visit is recommended to verify existing conditions, electrical panel capacity, attic access constraints, and hot water distribution configuration (including the suspected separate hot water service to the laundry room in Quarters 1). Coordinate the site visit with the Government Technical Coordinator.

2. Place of Performance and Period of Performance

2.1 Place of Performance. Work will be performed at Nathaniel P. Reed Hobe Sound National Wildlife Refuge Quarters:

13610 SE Federal Highway, Hobe Sound, FL 33455; and 13620 SE Federal Highway, Hobe Sound, FL 33455

2.2 Period of Performance. Anticipated period of performance is from Notice to Proceed (NTP) through completion within 45 calendar days. Contractor shall coordinate scheduled water shutoffs with occupants and the Government. The Government prefers minimal disruption and restoration of domestic hot water service the same day whenever practicable.

2.3 Normal duty hours are Monday through Friday 8:00 a.m. - 4:30 p.m. Contractor shall provide an after-hours emergency contact for active work periods.

3. Scope

3.1 General Scope. Contractor shall provide all labor, supervision, materials, equipment, tools, transportation, and incidentals to remove and properly dispose of existing domestic hot water systems and install new tankless domestic hot water systems serving Quarters 1 and Quarters 2, in locations approved by the Government. Contractor shall verify existing conditions and size/select equipment to meet performance requirements.

3.2 Quarters 1 Requirements. Contractor shall:

• Remove and dispose of the existing two (2) tank-type electric water heaters currently located in the attic.

• Provide and install a tankless domestic hot water system(s) capable of supplying hot water demand for the Quarters 1 residence and the laundry room.

• Verify and document the existing hot water distribution (including whether a separate heater serves the laundry room) and provide any required piping modifications to ensure all required areas are served.

• Install isolation/shutoff valves, unions, and service valves consistent with manufacturer requirements to support maintenance and descaling.

3.3 Quarters 2 Requirements. Contractor shall:

• Remove and dispose of the existing one (1) tank-type electric water heater currently located in the attic.

• Provide and install a tankless domestic hot water system capable of supplying hot water demand for the Quarters 2 residence.

• Install isolation/shutoff valves, unions, and service valves consistent with manufacturer requirements to support maintenance and descaling.

3.4 Electrical Work (Base or Option). The tankless systems will require electrical evaluation and may require new/modified breakers, conductors, and panel space. Contractor shall:

• Inspect the existing electrical service/panels for Quarters 1 and Quarters 2 and determine capacity for the proposed tankless system(s).

• Provide and install any required breakers, wiring, disconnects, and associated electrical components in accordance with the National Electrical Code (NEC) and applicable Florida codes.

• Coordinate outages with occupants and the Government.

3.5 Location Considerations. The Government is interested in evaluating relocation of water heaters from attic spaces to a first-floor/ground-level location where feasible to reduce flood risk and facilitate maintenance. Contractor shall evaluate feasible locations during the site visit and recommend an installation location(s). Any relocation, wall/finish work, or significant rerouting of piping beyond standard connections shall be proposed as a separate priced option unless otherwise directed by the Government.

3.6 Permits and Inspections. There are no permitting requirements.

3.7 Codes/Standards. All work shall comply with the most current applicable editions of: Florida Building Code; Florida Plumbing Code; National Electrical Code (NFPA 70); manufacturer installation instructions;

and all applicable safety standards.

3.8 Protection of Property and Occupants. Quarters may be occupied during work. Contractor shall protect all surfaces, maintain clear walkways, and control debris. Contractor shall isolate water and power safely, prevent water discharge into structures, and immediately address any active leaks.

Contractor shall remove all construction debris daily and restore the work areas to clean, safe conditions.

4. Deliverables and/or Delivery Schedule

4.1 Deliverables. Contractor shall provide the following, at a minimum:

• Pre-installation submittals (within 5 business days of award, prior to procurement/installation):

product data sheets/cut sheets for proposed tankless unit(s), accessories, and any required electrical components; proposed installation locations; and a brief work plan/schedule.

• Proof of licenses (plumbing; electrical if applicable) and insurance prior to mobilization.

• Pricing schedule clearly separating: (a) Base work; (b) Optional electrical modifications (if not included in base); (c) Optional permitting/inspection costs; (d) Optional relocation from attic to first-floor location; (e) Optional leak detection and/or automatic shutoff devices (if proposed).

• Commissioning/functional test results at completion: demonstrate hot water delivery at multiple fixtures, verify stable temperature control, and verify no leaks under operating pressure.

• Operations and Maintenance (O&M) information: manufacturer manuals, warranty documentation, and recommended maintenance/descaling procedure and schedule.

• As-built documentation at completion: final equipment list (manufacturer/model), final locations, and a short narrative of any piping/electrical changes made.

4.2 Schedule. Contractor shall coordinate installation dates with the Government and occupants.

Planned water shutoffs shall be communicated at least 48 hours in advance. Emergency shutoffs or schedule changes shall be communicated immediately.
