UNSPSC 31101906: Aluminum investment casting

Aluminum object cast from investment molds

UNSPSC 31101906 Aluminum investment casting is a Commodity code that in state and local procurement currently captures pump repair, maintenance, and parts replacement services rather than the manufacturing or casting of aluminum components. The City of Atlanta Department of Watershed Management issued a multi-step sealed bid solicitation in May 2026 for comprehensive pump service across nine classifications—vertical turbine, horizontal split case, submersible, centrifugal, vertical chopper, progressing cavity, piston-type positive displacement, Watson Marlow, and vacuum and hydraulic pumps—that reveals the actual buying pattern under this code designation. Vendors must demonstrate full-service capability including parts procurement, installation, disassembly, inspection, repair to OEM standards, reassembly, startup, and detailed reporting, with personnel certified in pump shaft alignment, welding, and confined-space entry. Successful bidders require a functional machine shop, field service equipment, and the ability to supply 90 percent of required parts within 24 hours and the remaining 10 percent within 72 hours under a one-year parts and labor warranty. The code has seen limited recent state and local activity; the Atlanta opportunity represents the primary documented solicitation under this UNSPSC designation in the current cycle.

The Atlanta procurement, issued by a municipal water utility as an IFB with a May 29, 2026 response deadline, indicates activity concentrated in Georgia. The solicitation includes a pre-solicitation conference and prequalification phase prior to formal bidding, with no disclosed set-aside or incumbent preferences. Vendors must own or access a machine shop and provide their own tools and safety equipment, with travel and facility inspection costs borne by the vendor. Watson Marlow work requires manufacturer-certified distributor status, and Xylem-brand Flygt pumps require Xylem certification. The contract terms offer a five percent early-payment discount for invoice settlement within ten days, otherwise net 30. No contract ceiling or award value is disclosed in the available documentation. The code's narrow recent activity and the mismatch between its nominal scope (aluminum investment casting) and the actual work being solicited (pump service and repair) suggest either misclassification in the purchasing system or minimal use of this code for its intended purpose in state and local procurement.
