DKGV 1161220 Repair Condensate Pipe Pier XRS Attachment 2 Pipe Drawing.pdf

This is a technical drawing/specification document for pier structural repairs and modifications at an NW Tank facility. The document provides detailed engineering plans for replacing and upgrading piping support systems and seismic bracing components.

The project requires the contractor to repair or replace a 3" condensate pipe section, remove a 3/4" low point drain valve and associated piping, and replace existing vertical hangers and components with equivalent 316 stainless steel (SS) components. The work includes installation of seismic sway, traverse, and longitudinal 316 stainless steel bracing near the same locations as the vertical hangers. All bracing materials must be 316 SS. Key specifications include post-installed adhesive anchors with varying ultimate tension and shear strengths depending on embedment depth and size (ranging from 1.5" to 3.5" embedment depths, with ultimate tension loads from 2,880 to 14,900 lbs and ultimate shear loads from 2,025 to 10,890 lbs). The contractor must perform pier scanning prior to installation to determine anchorage requirements, use qualified welding procedures per ASME standards, perform hydrostatic testing of repaired piping per code requirements, and verify all piping work meets applicable standards. The document includes detailed installation notes, manufacturer instructions for adhesive anchors, and reference specifications for materials and installation procedures. No response dates, award dates, pricing, or federal agency information is provided in this technical specification document.
