UNSPSC 31102311: Brass plaster mold casting

Brass object cast from plaster molds

UNSPSC 31102311 Brass plaster mold casting, a Commodity code, shows minimal relevant recent activity in state and local procurement. The most recent opportunity posted under this code — a May 2026 pre-advertisement notice from the City of Atlanta Department of Watershed Management — solicits comprehensive repair, maintenance, installation, and parts replacement services for nine classifications of industrial pumps across municipal water management facilities. This work falls squarely within pump service and parts supply, not brass plaster mold casting. The mismatch suggests either a cataloging error in the state and local system or a limited-activity code that does not reflect the substantive procurement happening under its nominal scope.

The Atlanta opportunity, published May 8, 2026 with a prequalification deadline of May 29, 2026, is structured as a multi-step sealed bid process (prequalification followed by an Invitation for Bid) covering nine pump groups — including Vertical Turbine, Horizontal Split Case, Submersible, Centrifugal, Vertical Chopper, Progressing Cavity, Piston Type Positive Displacement, Watson Marlow, and Vacuum and Hydraulic Pumps. Vendors must demonstrate certified machine shop access, field service capability, and personnel trained in pump shaft alignment, welding, confined space entry, and OEM-standard repair. The City requires 90 percent parts availability within 24 hours and one-year warranties on all work, with no disclosed award floor or ceiling. This appears to be the only recent state and local opportunity traceable to the brass plaster mold casting code in the available source material, suggesting the code sees little active use for its nominal commodity or has been incorrectly tagged for unrelated pump-service work.
