NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION (NOAA)

STATEMENT OF WORK (SOW) FOR ROOF AND HVAC REPLACEMENT

1.0 GENERAL

1.1 BACKGROUND

The National Weather Service (NWS) Eastern Region (ER) has a requirement for Roof and HVAC Replacement.

The NWS ER provides critical weather forecasts and warnings for the eastern portion of the United States, including adjacent waters and ocean areas, for the protection of life and property and the enhancement of the national economy. This Weather Forecast Office (WFO) site is used to make timely meteorological observations which aids in this effort. This location operates 24x7 with staffing and critical equipment.

New roof and HVAC equipment installations are necessary to prevent asset failures that could result in downtime, safety issues, and operational shutdowns. Focus is on preventing water intrusion from the exterior and lack of proper cooling to critical electronic equipment.

The existing roofs have a layer of Ethylene-Propylene-Diene-Monomer (EPDM) synthetic rubber membrane atop 4” rigid insulation board, ½” firestop board, and then a vapor barrier. Also, these flat roofs were over-sprayed with an ArmorThane elastomeric spray coating in past attempts to seal leaks.

The existing HVAC equipment to be replaced with brand name or equal specifications are as follows:

Quantity (2): Condensing Units ,12.5-ton cooling capacity (ACU-1, ACU-2)

● TRANE model TTA150E400AA

Quantity (2): Air Handling Units, 10-ton cooling capacity (AC-1, AC-2)

● TRANE model MCC10

Quantity (1): Condensing Unit, 10-ton cooling capacity (ACU-3)

● TRANE model TTA120E400AA

Quantity (1): Air Handling Unit, 6-ton cooling capacity (AC-3)

● TRANE model MCC06

1.2 SCOPE

1.2.1 The scope of work is to replace two (2) existing flat roofing systems with new roofing systems, replace three (3) existing Air Handling Units (AHUs) and three (3) existing Condensing Units with new units of the same capacity, replace all exterior ductwork, clean all interior ductwork, re-balance each HVAC System using a certified air balance company employing TAB certified technician(s), and verify system operation.

Work includes demolition and total removal of approximately 5,760 sq ft of an existing flat roofing system down to the metal deck at the WFO, and approximately 500 sq ft similarly at the adjacent Diesel Driven Generator (DDG)/Storage Building. The existing WFO HVAC equipment will be replaced in kind with new HVAC equipment. Both buildings will remain completely functional and must be fully protected at all times during the construction work. All ingress/egress to facility and

April 14, 2026 Rev.0 Page 1 of 21 pedestrian walkways must be maintained with overhead protection when construction is occurring at/over these areas. All interior duct cleaning and re-balancing of HVAC systems will be performed within a 24x7 office environment.

The building will remain completely operational with staff during this work. All employees, visitors, building interiors and Government equipment must be fully protected at all times during this construction work.

1.3 OBJECTIVE

The purpose of this contract is to replace existing roofs and HVAC equipment (air handling and condensing units) that are beyond their life expectancy. A planned replacement is necessary to prevent: (a) outside environmental conditions from entering the building per industry standards and (b) overheating of the facility in the event of catastrophic HVAC equipment failure.

The new roofing system must be 100% reliable and warranted by the roofing manufacturer for a minimum of twenty (20) years. The roofing work accounts for roughly 56% of this requirement.

The HVAC work must include new Air Handling and Condensing Units, exterior duct replacements, interior duct cleaning, and rebalancing of the system in order to provide conditioned air to the building per industry standards. The HVAC work accounts for roughly 44% of this requirement.
