About this file
This document is a mechanical floor plan set for a construction project showing both demolition and new work phases. The plan is drawn at a scale of 1/4" = 1'-0" and includes detailed layouts of mechanical systems, equipment, and piping installations within a building space.
The demolition plan (C1) identifies existing mechanical systems, refrigerant piping, and components scheduled for removal, including concrete drain routes and wall penetrations requiring sealing. The new work plan (A1) shows the proposed mechanical layout with new HVAC equipment placement, refrigerant piping systems, ductwork, and associated infrastructure. Key elements depicted include multiple air conditioning units (ACCU-1 through ACCU-4), distribution systems (DSS-1 through DSS-4), duct fittings (DF-1), and existing trees and shrubs to be preserved. The keynotes section provides specifications for refrigerant piping installation, concrete drain routing, exterior wall sealing, ductwork configuration, air conditioning unit placement, and equipment maintenance requirements. The plan includes a legend identifying symbols for refrigerant piping and pipe turning direction, with a graphic scale provided for reference. The drawing was last modified on 6/11/2026 and is filed under drawing number M-101.
