This document is a design specification for an electrical switchgear roof structure as part of the Recirculating Aquaculture Upgrades project at the National Cold-Water Marine Aquaculture Center (NCWMAC) in Franklin, Maine, dated February 18, 2026.

The roof structure is designed to house electrical switchgear equipment and features overall dimensions of 8'-10" wide by 6'-0" tall. The structure includes a metal deck roof, 3x3 tube framing, and accommodates a 24"x36" unit with space reserved for a future unit. The plan view shows the layout with specific spacing measurements (8", 3'-0", 1'-6", 3'-0", 8" horizontal divisions and 2'-0" vertical sections), while the front elevation illustrates the metal deck, switchgear positioning, and tube framing configuration. Key material and construction requirements include: roof material matching the main building roof in thickness, color, and profile; sloped roof design to properly shed rain, snow, and ice; and painting of all steel columns and roof framing to match the existing building. The structure is designed to integrate seamlessly with the existing facility's architectural and structural standards.
