UNSPSC 31101806: Aluminum shell mold casting

Aluminum object cast from shell molds

UNSPSC 31101806 Aluminum shell mold casting (Commodity) covers metalworking and foundry production, but the recent state and local activity under this code does not reflect aluminum casting work. The City of Atlanta Department of Watershed Management posted a multi-step sealed bid process in May 2026 for pump repair, maintenance, installation, and parts replacement services—work that falls outside aluminum shell mold casting scope. The solicitation calls for full-service support across nine pump classifications, including Vertical Turbine, Horizontal Split Case, Submersible, Centrifugal, Vertical Chopper, Progressing Cavity, Piston Type Positive Displacement, Watson Marlow, and Vacuum and Hydraulic Pumps. Qualified vendors must own or have full access to a functional machine shop, field service equipment, and personnel certified in pump shaft alignment, welding, and machinist work, with training in permit-required confined space entry. All work must meet OEM standards, OSHA requirements, and applicable safety codes. The code shows minimal relevant recent activity for aluminum foundry work; the single recent opportunity posted under this code number is unrelated to the commodity's nominal scope.

The Atlanta Department of Watershed Management issued the pump repair and parts solicitation with a prequalification phase preceding an Invitation for Bid (IFB), with a submission deadline of May 29, 2026. The jurisdiction requires vendors to supply 90 percent of parts within 24 hours and the remaining 10 percent within 72 hours, provide one-year warranties on parts and services, and submit itemized annual purchase reports. Watson Marlow pump work must be performed by manufacturer-certified distributors, and Xylem (Flygt) pump work must be performed by Xylem manufacturer-certified distributors. No set-aside designations were identified, and the City reserves the right to increase or decrease quantities and is under no obligation to award to a single bidder or commit to a minimum contract amount. No award value or budget range was disclosed. Business development professionals evaluating this code should recognize that recent state and local posting activity under UNSPSC 31101806 does not align with aluminum foundry casting procurement.
