PSC Y1GA

Overview

The Product Service Code (PSC) system is a government-wide taxonomy used in federal procurement to classify what is purchased across contracts and awards; PSCs populate FPDS data fields, support spend analysis, and are governed by the PSC Manual on Acquisition.GOV. The PSC Y1GA designates construction of ammunition storage buildings and is recorded on contract actions when the predominant effort is the construction of facilities used to store ammunition and related munitions-storage structures. Typical use includes new-build magazines, igloo-style earth-covered storage, and associated site improvements required to support secure munitions stockpiles. Agencies select a PSC that best represents the primary product or service for an FPDS action; construction actions whose main purpose is ammunition-storage building construction should be reported under Y1GA. ¹

What this PSC covers

• Ammunition-storage facility construction and associated site works. ¹
• Earth-covered magazines and igloo-type storage structures. ¹
• Above-ground and below-grade munition magazine construction. ¹
• Associated utilities and site improvements required for ammunition storage. ¹
• New-build storage buildings for governmental munitions stockpiles. ¹

How FPDS records and uses this PSC

Agencies are instructed in the PSC Manual to select the PSC that represents the predominant product or service for an FPDS action; therefore, construction contracts primarily for ammunition-storage buildings should be reported under Y1GA. ¹

FPDS tools (ezSearch / FPDS portals) enable filtering and reporting by PSC so users can locate historical obligations, solicitations, and award records tied to a PSC such as Y1GA. ²

Frequently asked questions

• When should a contract be coded to Y1GA rather than another construction PSC?
  If the predominant scope is construction of buildings dedicated to ammunition or munitions storage (including magazines or igloo-style earth-covered magazines), code the action to Y1GA. The PSC Manual requires selection based on the predominant product or service reported in FPDS. ¹

• Which NAICS codes apply to projects coded under Y1GA?
  The PSC Manual does not publish an authoritative NAICS crosswalk for every PSC; NAICS pairing is determined case-by-case by reporting agencies and solicitation language. Not specified by official sources ¹.

• Is repair, alteration, or maintenance of ammunition storage covered by Y1GA?
  No. Repair, alteration, or maintenance actions are assigned maintenance/repair PSCs (for example, Z1GA for maintenance of ammunition storage buildings) rather than the construction PSC Y1GA. The PSC Manual separates construction (Category Y) from maintenance/repair (Category Z). ¹

• Where can historical awards and solicitations coded to Y1GA be searched?
  FPDS ezSearch and related FPDS portals provide contract-level search and reporting by PSC; filter results by the PSC code to find award history and obligations tied to Y1GA. ²
