PSC Y1LB

Overview

The Product Service Code (PSC) system is a government-wide taxonomy that classifies products and services in federal procurements to standardize reporting, analysis, and spend-tracking across systems such as FPDS and SAM; the PSC Manual maintained by GSA/FAS documents code definitions and management procedures.¹

The PSC Y1LB is described in the PSC Manual as “Construction of Highways, Roads, Streets, Bridges, and Railways” and explicitly includes resurfacing. Agencies use Y1LB to record the predominant construction activity on contract actions reported in FPDS (data element 8A).¹

What this PSC covers

• Heavy civil roadway construction (new alignments and full‑depth construction)
• Bridge construction and major bridge replacement
• Railbed and railway structure construction
• Street and local road construction within public right‑of‑way
• Resurfacing, milling, and pavement rehabilitation
• Associated site work directly tied to roadway/rail construction (grading, drainage)
• Major structure demolition needed for replacement or new construction

FPDS reporting and usage

Agencies record the PSC in FPDS data element 8A and are instructed to select the PSC that represents the predominant product or service for the contract action; environmental attributes are captured separately in data element 8L. FPDS search and reporting tools allow filtering or reporting by PSC code to analyze spend and awards by “what” was bought.²

NAICS mapping (clarification)

The PSC Manual provides code definitions and category alignments but does not mandate a single fixed NAICS mapping for each PSC in the narrative code list. Where agencies pair PSCs with NAICS on solicitations or awards, NAICS selection is reported in FPDS as a separate data element and may vary by procurement. Not specified by official sources.¹

Frequently asked questions

• How is Y1LB selected on an award record? The PSC is entered in FPDS data element 8A and should reflect the predominant construction activity of the award. If multiple activities exist, select the PSC representing the primary scope by dollar value or effort.¹

• Does Y1LB cover resurfacing and pavement rehabilitation? Yes. The PSC Manual explicitly lists “Includes: Resurfacing” for Y1LB, so resurfacing and similar pavement rehabilitation activities are encompassed.¹

• Are specific NAICS codes required when using Y1LB? The PSC Manual defines the service code but does not assign a mandatory NAICS mapping within the narrative code list; NAICS is reported separately in FPDS and may differ by procurement. Not specified by official sources.¹

• Where can searches for awards by PSC be performed? FPDS provides search and reporting features that permit filtering awards by PSC and NAICS; consult FPDS help and user guidance for search techniques and report configuration.²
