These are detailed HVAC (Heating, Ventilation, and Air Conditioning) engineering design drawings for the upper deck house of the Dredge Yaquina, a vessel likely operated by the U.S. Army Corps of Engineers. The drawings, labeled with engineering document numbers F107243 and Y-3878-18, provide comprehensive technical schematics for the upper deck HVAC system, including multiple sections and elevation views.

The technical drawings include intricate details of various spaces such as the Officer Mess, Crew Mess, Incinerator Room, Exercise Room, Fan Room, Galley, and Emergency Generator Room. The documents show precise measurements, airflow rates (in CFM - cubic feet per minute), ductwork configurations, equipment placement, and material specifications. The drawings cover multiple deck levels and include detailed notes about equipment installation, material requirements, and specific technical configurations for the vessel's ventilation and climate control systems.
