PSC Z1LB: Maintenance of Highways, Roads, Streets, Bridges, and Railways — Active Federal SAM.gov Contracts & NAICS Crosswalk

Federal procurement intelligence, spending breakdown, NAICS/NIGP crosswalk, and contract capture guide for PSC Z1LB (Maintenance of Highways, Roads, Streets, Bridges, and Railways).

Product and Service Code (PSC) Z1LB — Maintenance of Highways, Roads, Streets, Bridges, and Railways — 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 $1.8 Billion annually under PSC Z1LB, with 290+ 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 Z1LB specifies the exact real property maint (z1) deliverable being purchased on the contract line item (CLIN). In federal solicitation architecture, PSC Z1LB is most frequently paired with Primary NAICS 237310 (Highway, Street, and Bridge Construction), which carries an SBA small business size standard of $45.0 Million. Major buying commands—led by Department of Defense (46% of spend), Department of the Interior (NPS/BLM) (28%), and Department of Agriculture (USFS) (18%)—use PSC Z1LB to categorize statements of work encompassing Asphalt Crack Sealing, Slurry Seal, Chip Seal & Pothole Patching on Federal Roads; Airfield Runway Rubber Removal, Joint Resealing & Airfield Striping; and Bridge Deck Washing, Scour Protection, Expansion Joint & Guardrail Maintenance. Understanding how contracting officers cross-walk PSC Z1LB with NAICS 237310 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 Z1LB utilize a mix of open-market SAM.gov solicitations and pre-competed contract vehicles such as FHWA / DoD. Depending on the acquisition threshold and market research results from Sources Sought notices, contracting officers frequently restrict PSC Z1LB 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 Z1LB 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 Z1LB maps directly to NIGP Commodity/Service Code 913-71 (Maintenance and Repair, Highway and Road (Including Asphalt Milling and Resurfacing)) used by state procurement portals, municipal purchasing departments, public universities, and K-12 school districts.
