UNSPSC 73151500: Assembly services

UNSPSC 73151500 Assembly services, a Class code, encompasses factory assembly and testing of water treatment equipment components, potable water distribution apparatus, and specialized industrial valve and flow control assemblies for municipal utilities. State and local governments procure pre-assembled flow controllers, butterfly valves, venturi meters, and related piping components ready for installation at water treatment plants, wastewater facilities, and distribution infrastructure. The code covers complete factory assembly operations, pressure testing to accuracy standards (typically ±0.5 percent of actual flow), and the supply of assembled equipment paired with operation and maintenance documentation. Issuing bodies are primarily municipal water and wastewater utilities and city procurement offices acting on behalf of water departments; school districts and county governments occasionally procure through interlocal purchasing agreements when bundled with municipal contracts.

Recent activity concentrates in Texas. The City of Lubbock, Texas, issued ITB 26-19653-YB on May 12, 2026, with a response deadline of May 27, 2026, seeking a factory-assembled 16-inch venturi-type flow controller and AWWA C504-compliant butterfly valve assembly for the North Water Treatment Plant, with components constructed to ASTM A536 Grade 65-45-12 cast iron specifications and Type 316 stainless steel throat liners, factory-tested to ±0.5 percent accuracy, and fitted within a 46.5-inch maximum space envelope. The City of Philadelphia posted a micro purchase solicitation (B2626859) on April 10, 2026, for OVA Storage, due April 24, 2026, capped at $43,000 with no line-item detail in the available source material; the geographic and commodity scope diverges from the Lubbock water treatment assembly work and reflects minimal relevant activity under the code in that jurisdiction. Lubbock's ITB included a local preference provision allowing local bidders within five percent of the lowest bid consideration if deemed to offer better combined value and economic development benefit, though the preference applies only to contracts under $500,000. The Lubbock procurement is open to all qualified vendors meeting specifications; no set-aside or restricted-competition designations apply.
