Attach 2 - Drawings (26RA003).pdf

This is a structural engineering drawing document for building roof framing, specifically detailing modifications to an existing roof structure. The drawing provides comprehensive specifications for removing existing bracing, installing new horizontal bracing, and relocating structural elements to accommodate changes in the roof configuration.

The document specifies key construction requirements including: removal of existing horizontal cross-bracing located at the roof edge and replacement with new horizontal bracing relocated to the underside of the roof above; installation of new cross-bracing prior to removing existing bracing; and relocation of the south end of the brace requiring removal and reinstallation of a metal panel divider wall. The structural design must function as a unit during the structure's service life, with the contractor responsible for providing required engineering, layout, erection procedures addressing stability, weld procedures, surveying verification, tolerance evaluation, and thermal movement assessment. All shop drawings must reference the structural drawing number and be submitted in electronic format only. Welding requirements mandate current evidence of possession of minimum AWS D1 certifications, with all grooved welds requiring complete penetration and specified weld sizes. The document includes detailed steel material specifications, welding electrode requirements, and field measurement verification procedures. Contractor construction and erection must comply with OSHA requirements, and shop drawings require engineer approval before proceeding with corrective work. No specific contract vehicles, set-asides, federal agencies, response dates, or pricing terms are identified in this technical drawing document.
