Statement of Work National Oceanic and Atmospheric Administration (NOAA)

National Marine Fisheries Service (NMFS) Northwest Fisheries Science Center (NWFSC)

Montlake Laboratory Room 246E Chemical Fume Hood and Exhaust System

1. Organization. The Northwest Fisheries Science Center (NWFSC) is a marine research organization owned and operated by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Marine Fisheries Service (NMFS). NWFSC has five (5) major campuses in Washington and Oregon, with its regional headquarters located in Seattle, WA.

2. Project Location. The project described in this Statement of Work (SOW) is in the East Building on the Montlake Laboratory Campus located at 2725 Montlake Blvd. East, Seattle, WA 98112. This site is a multi-building campus supporting marine research and housing more than 240 staff. The facility includes various laboratories, workshops, office spaces, and conference rooms across structures built from 1931 to 2007. The East Building on Montlake Campus was constructed in the late 1960’s. NWFSC completed the HVAC upgrades in FY25. While there are many changes the ductwork in the building, the exhaust stacks servicing fume hoods have not changed. See Figure 1 of Exhibit A for the original exhaust fume hood near room 246E.

2.1. Lab 246E is on the second floor in the East Building. Photos 1 and 7 of Exhibit B show the interior of this space. The cabinets and countertop on the east wall will be cleared by the Government to accommodate the new fume hood installation. Photos 3 to 5 of Exhibit B show the available electrical panel and utility chase outside the Lab 246E entry door in the hallway.

Photos 6 and 6 of Exhibit B show typical rooftop exhaust stack, penetration platform, and electrical power.

3. Project Objective. The purpose of this project is to furnish, install, integrate, test, and commission a floor-mounted chemical fume hood and exhaust system capable of safely capturing and exhausting methylene chloride, flammable solvents, and corrosive chemical vapors in a laboratory environment. The system shall be fully operational, capable of demonstrating compliance through testing and commissioning, and suitable for continuous use in a federally operated research laboratory. All work shall meet applicable federal, state, and local requirements. If none exist, all work shall meet industry standards (i.e., IMC Section 510 Hazardous Exhaust System).

4. PERFORMANCE REQUIREMENTS. The Contractor shall provide a complete, integrated system that meets all functional, safety, and operational requirements defined herein.

The Contractor is solely responsible for field verification of all conditions necessary to complete the work, design, engineering, material selection, installation, coordination, testing, and commissioning necessary to achieve the required performance outcomes. The Contractor shall furnish all labor, supervision, materials, equipment, tools, transportation, and incidental services necessary to complete the work unless specifically identified as Government-furnished in this

SOW.

4.1. System Performance. The system shall:

4.3.5. Be designed to prevent creation of ignition hazards (e.g., static charge accumulation associated with non-metal components) and unsafe chemical interactions.

4.3.6. Discharge exhaust in a manner that prevents re-entrainment into occupied areas or building air intakes.

4.3.7. Maintain structural integrity under continuous operation and environmental exposure.

4.3.8. Be designed to prevent accumulation of liquid condensate or chemical residue that could impair system performance or create a safety hazard.

4.3.9. Be designed to permit routine inspection, maintenance, and replacement of major system components without requiring demolition of permanent building construction.

The exhaust system shall be designed to minimize pressure losses and excessive velocity while maintaining the required containment performance.

4.4. Electrical and Static Control. The system shall:

4.4.1. Integrate safely with existing building electrical systems.

4.4.2. Comply with applicable electrical codes and standards.
