Concourse CON_Tractel _Stamped_Calcs.pdf

This document is a comprehensive engineering design and calculation package for a CONCOURSE Building window washing equipment project prepared by Tractel Ltd.'s Swingstage Division for Denver Veterans Affairs (KIEWIT-TURNER JOINT VENTURE), located in Aurora, Colorado (Project No. 1-8C40, dated 22-Jan-14).

The package contains 79 sheets of detailed structural and mechanical calculations, specifications, and design documentation covering all major components of the suspended window washing system. Key components include: STD DAVIT Pedestal & Port Base, DAVIT Mast 5000, DAVIT Arm Support 5000, Monorail Track and Support, Powered Trolley, Rolling Outrigger with components, and Safety Line "TRAVSMART" Support. Design specifications establish a safety factor of 4 against failure (performance factor Φ = 1) for all equipment. Material standards include CAN/CSA G40.21 steel (Type 44W and 50W grades) with specified yield and tensile strengths, and ANSI/AWS D1.2-97 aluminium alloys (6061-T6 and 6351-T6). The calculations document detailed stress analysis for suspension loads of 1.25 kips with 8'-6" boom reach, including bearing capacity checks, weld sizing, bolt specifications, and component interactions. All major structural elements—including the mast pipe, pedestal configuration, boom extrusion, monorail track, and outrigger trolley assemblies—are analyzed for flexural strength, shear capacity, torsional properties, and combined stress conditions to ensure safe operation within specified load parameters.
