UNSPSC 73181002: Electro discharge machining EDM services

UNSPSC 73181002 Electro discharge machining EDM services is a Commodity code under which state and local governments procure precision machining and fabrication work for equipment repair, maintenance, and reconstruction across water treatment, transportation, and public facilities. The recent opportunities block shows minimal direct alignment with the code's EDM-specific scope; instead, the sourced solicitations span general machine shop services, equipment fabrication, water utility infrastructure rebuild, and specialty fabrication needs that fall outside traditional EDM work (wire erosion, cavity sinking, or precision electrode machining). The most concrete match appears in precision machine shop term contracts where milling, boring, bushing, turning, welding, and fabrication of specialty items for pump and motor repair are solicited on an as-needed basis. Issuing bodies include water authorities, county governments, transit authorities, and municipal departments seeking contractor capability to handle multiple machining disciplines at their own facilities or off-site vendor shops. Water and wastewater utilities appear most active, followed by county public works and transportation authorities managing fleet and infrastructure equipment.

Geographic activity centers in Georgia and Florida based on recent postings. The Macon Water Authority (Georgia) issued a sealed bid for gravity thickener and clarifier rebuild at Rocky Creek WRF (due October 20, 2026), and DeKalb County issued solicitations for machine shop services and IT/low-voltage infrastructure reconstruction (bids June–July 2026). Palm Beach County Board of County Commissioners posted an IFB for off-site precision machine shop services supporting water and wastewater facilities across five county locations, with a 12-month term and estimated $188,750 expenditure (bid due June 24, 2026). The Orange County Transportation Authority (California) solicited quotes for a Scotchman 50-ton ironworker fabrication machine under RFQ 250358, delivery and installation at Santa Ana Maintenance Base (bid due June 2, 2026, estimated $35,772). The City of Atlanta issued a separate tire repair and disposal IFB unrelated to EDM scope. The code shows light to moderate state and local activity concentrated in utility and transportation authority procurement rather than specialist EDM firms; general machine shop and fabrication capability appears more commonly solicited than electro-discharge machining specifically.
