PSC Y1LB: Construction 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 Y1LB (Construction of Highways, Roads, Streets, Bridges, and Railways).

Product and Service Code (PSC) Y1LB — Construction of Highways, Roads, Streets, Bridges, and Railways — is an official federal procurement classification within Portfolio Y — Construction of Structures and Facilities 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 $4.6 Billion annually under PSC Y1LB, with 360+ 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 Y1LB specifies the exact construction (heavy civil) deliverable being purchased on the contract line item (CLIN). In federal solicitation architecture, PSC Y1LB 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 Transportation (FHWA) (42% of spend), U.S. Army Corps of Engineers (USACE) (34%), and Department of the Interior (NPS/BLM) (15%)—use PSC Y1LB to categorize statements of work encompassing Federal Lands Highway Division (FLHD) Roadway Paving, Grading & Bridge Replacement; Military Base Heavy Tank Trails, Perimeter Patrol Roads & Overpass Structures; and Airfield Runways, Taxiways, Concrete Aprons & Arresting Gear Foundations. Understanding how contracting officers cross-walk PSC Y1LB 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 Y1LB utilize a mix of open-market SAM.gov solicitations and pre-competed contract vehicles such as FHWA / USACE. Depending on the acquisition threshold and market research results from Sources Sought notices, contracting officers frequently restrict PSC Y1LB 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 Y1LB 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 Y1LB maps directly to NIGP Commodity/Service Code 913-27 (Construction, Highway, Road, Street, and Alley) used by state procurement portals, municipal purchasing departments, public universities, and K-12 school districts. InTandem's automated government contracting platform continuously monitors live SAM.gov notices tagged with PSC Y1LB alongside matching state and local NIGP 913-27 bids, enabling capture teams to uncover hidden opportunities and generate compliant proposals faster.
