Project Speciality

Standards of Process Considered: 1. Fabrication CADmep 2015 for 3D modeling 2. LOD 400 for modeling 3. Equipment, fitting, fixture modeling was based on cut-sheet/submittals, depending on BIM requirements Pipe Material - Copper, Steel Sheet Metal Requirement Specifications - Duct less that 17” in width or depth constructed with S&D connectors- Duct 17” & greater constructed with IMCOR TDC connectors- Standard length for duct with IMCOR TDC connectors was 56 ¼”, constructed on coil line- Standard length for duct with S&D connectors was 59”, constructed on coil line- Cut length duct was drawn as straight Cut (2xL)- Reducing transitions consisted of 2” extension in and out for TDC - Square to round transitions required Ward J connector on square end with 1 ½” throat- Rectangular elbow over 45 degrees required turning vanes

Our scope of work for the project included 1. 3D BIM Model Creation for Sheet Metal, Mechanical Piping including Hanger/Support, Equipment Modeling and Associated Fittings Sheet Metal 3D ModelA. Apron Level - Sector S02, 03, 04, 05, 06, 07 & 12B. Passenger Level - Sector S01, 02, 03, 04, 05, 06 & 07C. Roof-Sector S02, 03, 04, 05, 06 & 07 Mechanical Piping 3D ModelD. M1-2-001 SiteE. Apron Level - Sector S02, 03, 04, 05, 06, 07 & 12F. Passenger Level - Sector S01, 02, 03, 06, 07 & 12G. Roof - Sector S032. Clash Coordination with other trades - Basic Coordination was done by us and other trade coordination was done as per the clash report provided by the client. We run clashes in Naviswork and created “viewpoints” to identify individual clashes and resolve clashes as suggested by the client . 3. Preparation of Shop Drawing/2D Drawings for Sheet Metal & Mechanical Piping showing annotations, dimensions & tagging. 4. BOQ (Mechanical QTO) - Detailed QTO generated from clash free 3D model 5. As-Built Model & Drawings Input Data - Engineered/Permit Drawing Set

Challenge - 1. Missing Information - Missing Duct Size, Duct size mismatch (48x24 branch out from 72x20 main), Revised Size for Connection when 120X36 branch got connected with 200 X30 duct (Apron Level Area 1) Requested client to review and advise for the Solution -resize and provide the revised size for connection Challenge - 2. Space Constrain - Duct clash with wall due to space constrain, Duct Clash with Ceiling due to Space Constrain, Sleeve Clash with Structure due to Space Constrain (Slabe Penet) We took client suggestion and used our expertise for resolving the matter Solution -
