PSC Y1GB

Overview

The Product Service Code (PSC) framework is a four‑character, governmentwide taxonomy used to classify the products and services acquired by federal agencies for reporting, analysis, and spend management in systems such as FPDS and SAM; the codes and management procedures are maintained in the PSC Manual on acquisition.gov. PSC Y1GB — Construction of Food or Grain Storage Buildings — is the official PSC short‑title used to record contract actions whose predominant deliverable is the construction of structures intended primarily to store foodstuffs or grain. The PSC Manual provides the short‑title descriptor and administrative guidance, but it does not itemize detailed technical scope, contractor work breakdowns, or a single mandatory NAICS crosswalk for every PSC code; those specifics are determined from procurement scope and supporting crosswalk documents. ¹

What this PSC covers

• Construction of food or grain storage buildings (PSC Y1GB). ¹
• Erection of enclosed bulk‑storage structures. Not specified by official sources. ¹
• Installation of silo, bin, or hopper structural systems. Not specified by official sources. ¹
• Ancillary structural work integral to a storage building (foundations, walls, roof). Not specified by official sources. ¹
• New construction projects where the primary purpose is storage of foodstuffs or grain. Not specified by official sources. ¹

Crosswalks and assignment notes

• PSC assignment principle: select the PSC that best describes the predominant product or service being purchased for the contract line item; a single contract may carry multiple PSCs across line items and FPDS records the applicable PSC for each line item. ¹
• The PSC Manual provides management guidance, activation and end‑date spreadsheets, and category‑management alignments. Specific technical scope, NAICS applicability, and detailed crosswalks are handled in supporting PSC‑management documentation rather than in the short descriptor alone. Contracting officers should use procurement scope, statement of work, and available crosswalk resources to determine appropriate PSC and NAICS coding. ¹

Frequently asked questions

• Q: When should PSC Y1GB be used on a contract action?
  A: Use PSC Y1GB when the predominant deliverable is construction of buildings intended primarily for storing food or grain. Line‑item coding should reflect the main work scope; supporting documentation and the PSC Manual guide selection. ¹

• Q: Is there an official NAICS mapped to PSC Y1GB?
  A: The PSC Manual provides descriptions and management tools but does not publish a single mandatory NAICS mapping inside the short descriptor. Determine NAICS applicability from the procurement scope and available crosswalks or supporting PSC documentation. ¹

• Q: What is the maintenance counterpart for construction PSCs like Y1GB?
  A: Maintenance and repair activities typically use the Z‑series PSCs. For food or grain storage buildings, the maintenance counterpart is PSC Z1GB; consult the PSC Manual for family‑level guidance. ¹
