Drawing - Mechanical PartB.pdf

These are mechanical engineering drawings for HVAC and piping systems prepared by the US Army Corps of Engineers. The document set includes seven sheets (M-121 through M-213) depicting first, second, and third floor plans for mechanical HVAC and piping installations across multiple building areas (A, B, C, and D).

The drawings contain detailed mechanical specifications including ductwork layouts, fan coil unit (FCU) locations, refrigerant piping configurations, condensate drain lines, and equipment connections. Key mechanical systems shown include HVAC first, second, and third floor plans for Areas C and D, mechanical piping plans for first, second, and third floors across Areas A and B, with keynote legends and general notes addressing ductwork standards per SMACNA, manual balance dampers, thermostat controls, ductwork transitions, and condensate drainage requirements. The sheets are marked with field annotations and include references to refrigerant piping sizes and specifications. All drawings are prepared for the US Army Corps of Engineers and are not construction documents but rather design/planning documents subject to field coordination with other building disciplines.
