PSC Z1PZ: Maintenance of Other Utilities — Active Federal SAM.gov Contracts & NAICS Crosswalk

Federal procurement intelligence, spending breakdown, NAICS/NIGP crosswalk, and contract capture guide for PSC Z1PZ (Maintenance of Other Utilities).

Product and Service Code (PSC) Z1PZ — Maintenance of Other Utilities — is an official federal procurement classification within Portfolio Z — Maintenance, Repair, and Alteration of Real Property managed by the General Services Administration (GSA) under the Federal Procurement Data System (FPDS) Product and Service Codes Manual. Across federal agencies, contracting officers obligate approximately $1.9 Billion annually under PSC Z1PZ, with 210+ Bids active solicitations, pre-solicitation notices, and task order RFQs circulating on SAM.gov and agency e-Buy portals. While a 6-digit NAICS code defines a contractor's overall industry and Small Business Administration (SBA) size standard, PSC Z1PZ specifies the exact real property maint (z1) deliverable being purchased on the contract line item (CLIN). In federal solicitation architecture, PSC Z1PZ is most frequently paired with Primary NAICS 237130 (Power and Communication Line and Related Structures Construction), which carries an SBA small business size standard of $45.0 Million. Major buying commands—led by Department of Defense (58% of spend), Department of Energy (22%), and Department of Veterans Affairs (11%)—use PSC Z1PZ to categorize statements of work encompassing High-Voltage Substation Transformer Testing, Switchgear Preventive Maintenance; Central Steam & Chilled Water Distribution Pipe Insulation & Valve Servicing; and Solar Array Cleaning, Inverter Servicing & Microgrid Battery Maintenance. Understanding how contracting officers cross-walk PSC Z1PZ with NAICS 237130 is critical because many agencies filter dynamic small business searches, GSA e-Buy distributions, and historical FPDS incumbent spend analyses by PSC rather than NAICS alone. Procurement teams issuing awards under PSC Z1PZ utilize a mix of open-market SAM.gov solicitations and pre-competed contract vehicles such as DoD / DOE. Depending on the acquisition threshold and market research results from Sources Sought notices, contracting officers frequently restrict PSC Z1PZ competitions to certified small businesses—including 8(a) Business Development participants, Service-Disabled Veteran-Owned Small Businesses (SDVOSB), Women-Owned Small Businesses (WOSB), and HUBZone firms. Offerors responding to PSC Z1PZ RFPs must demonstrate strict compliance with applicable FAR and DFARS clauses, deliverable quality standards, and supply-chain or labor regulations. For contractors expanding across both federal and state/local (SLED) markets, PSC Z1PZ maps directly to NIGP Commodity/Service Code 936-25 (Electrical, Substation, and Standby Power Generation Equipment Maintenance/Repair) used by state procurement portals, municipal purchasing departments, public universities, and K-12 school districts.
