UNSPSC 31101908: Zinc investment casting

Zinc object cast from investment molds

UNSPSC 31101908 Zinc investment casting is a Commodity code that in state and local procurement practice covers precision metal castings used in equipment components, though recent solicitation activity under this code does not reflect traditional zinc casting work. The City of Atlanta Department of Watershed Management posted a Pre-Advertisement Notice (Solicitation Number PE66062NONST2026000000372) on May 8, 2026, tagged to this code, for comprehensive pump repair, maintenance, installation, and parts replacement services across nine pump classifications—Vertical Turbine, Horizontal Split Case, Submersible, Centrifugal, Vertical Chopper, Progressing Cavity, Piston Type Positive Displacement, Watson Marlow, and Vacuum and Hydraulic pumps. The scope requires qualified vendors to provide full-service support including procurement, disassembly, detailed inspection, transportation, OEM-standard repair, reassembly, startup services, and photographic documentation. Vendors must own or have access to a functional machine shop, field service equipment, and personnel certified in pump shaft alignment, welding, and machinist work, with confined space entry training. All work must meet OSHA standards, lockout/tag out procedures, and manufacturer safety requirements. This is a single recent opportunity from a municipal water utility in Georgia, with response deadline May 29, 2026, structured as a multi-step sealed bid process with prequalification preceding an Invitation for Bid. The code shows little relevant recent activity aligned with zinc investment casting as typically understood; the tagged opportunity involves field pump service rather than precision casting manufacture or supply.
