About this file
This document consists of mechanical, HVAC, and demolition planning drawings for the Seattle Research Laboratories at the Seattle National Fisheries Research Center, Naval Station (NAVSTA) Fuget Sound, Seattle, Washington. The drawings were prepared by The NBBJ Group and Boulillon Christofferson & Schaefer.
The plans include a mechanical floor layout showing HVAC systems and piping configurations, a detailed HVAC plan for the dry lab on the first floor with labeled components and ductwork routing, and a mechanical room demolition plan. The supplementary photograph illustrates specific renovation work required in the mechanical room, including: increasing ductwork to 12 inches, demolishing the existing CR2 unit and replacing it with a Titus 1,500 CFM VAV box, retaining and reconnecting existing hot water heating supply and return lines, and cutting concrete to accommodate a new 14" x 18" duct. These technical drawings and specifications detail the mechanical systems modifications and demolition requirements for the laboratory facility renovation project.
