Attachment B - DWS Valves.xlsx

This is a materials list attachment (Attachment B - DWS Valves.xlsx) that itemizes approximately 31 isolation shutoff valves required for installation across multiple buildings at the Rocky Mountain Regional VA Medical Center. The spreadsheet details valve locations by building (A, B, D, E, F, G, H, K, L, and Connector), system type (domestic cold water [DCW], domestic hot water [DHW], and domestic hot water recirculation [DHWR]), material composition (primarily copper and stainless steel 316), and pipe sizes ranging from 1-1/2 inches to 8 inches in diameter. Most valves are designated for new installation ("Add Valve"), with one valve noted as already in place (Building L, row 25), and several identified with specific comments regarding building feeds and kitchen supply lines.

The attachment serves as a reference inventory for contractors responding to solicitation 36C25926R0057, with a notation that contractors must verify quantities and specifications. This list corresponds to the Statement of Work scope requiring contractors to install pre-built pipe sections with integrated shutoff valves using ice plug isolation techniques at an appropriate cleanliness level for domestic water supply systems. The valve specifications include grooved couplings or flange connections as appropriate, with pipe insulation required post-installation.
