PSC C1GZ

Overview

The Product Service Code (PSC) is the federal government’s standardized taxonomy for classifying what is being procured so agencies can track, analyze, and report spending. PSCs are maintained through the PSC Manual and are used in federal contracting data reported to the Federal Procurement Data System (FPDS). ¹

PSC C1GZ denotes “Architect and Engineering–Construction: Other Warehouse Buildings.” It is used when the principal requirement is architect‑engineer (A‑E) services tied to construction of warehouse facilities that are not otherwise specified under a more granular storage/warehouse PSC. The designation supports consistent FPDS reporting of A‑E construction services for warehouse projects and falls under Category C1 (A‑E–Construction), distinguishing design-focused procurements from Y‑series construction and Z‑series sustainment. ¹

What this PSC covers

• A‑E services in support of constructing warehouse buildings not otherwise categorized under specific storage facility PSCs. ¹
• Use when the outcome is a constructed warehouse and the contract’s predominant requirement is A‑E work (design and related engineering) rather than construction execution. ¹
• Scope includes “other warehouse” facilities distinct from ammunition, fuel, food/grain, or open storage facilities, which have separate PSCs. ¹
• Applies to A‑E–construction efforts for general storage, distribution, or logistics warehouses that do not fit named subcategories. ¹
• Selection in FPDS should reflect the predominant service bought; C1GZ is chosen when A‑E–construction for a warehouse is the principal requirement. ¹
• For construction execution of similar projects, agencies would use the corresponding Y‑series code (e.g., Y1GZ). ¹

How this code aligns to related facility lifecycle PSCs

• Planning/design (A‑E–construction): C1GZ — architect and engineer services for warehouse construction requirements. ¹
• Build/construct: Y1GZ — construction of other warehouse buildings. ¹
• Maintain: Z1GZ — maintenance of other warehouse buildings. ¹
• Repair/alter: Z2GZ — repair or alteration of other warehouse buildings. ¹
• Operate: M1GZ — operation of other warehouse buildings. ¹
• Lease/rent: X1GZ — lease/rental of other warehouse buildings. ¹

Frequently asked questions

• What does PSC C1GZ represent?

  • PSC C1GZ identifies A‑E services in support of constructing “other warehouse buildings,” meaning warehouse facilities not covered by more specific storage/warehouse PSCs. It belongs to Category C1 (A‑E–Construction) in the PSC Manual and is used when design and related engineering are the predominant requirements. ¹

• How is C1GZ different from Y1GZ or Z1GZ?

  • C1GZ is for A‑E–construction services tied to warehouse construction; Y1GZ is for construction execution; Z1GZ and Z2GZ cover maintenance and repair/alteration, respectively. This separation helps agencies classify work by lifecycle phase for reporting and analysis. ¹

• Does the PSC Manual provide a NAICS crosswalk for C1GZ?

  • Not specified by official sources ¹. The PSC Manual defines PSC scopes but does not publish definitive NAICS mapping tables. Agencies typically infer NAICS based on the nature of A‑E services and the predominant work described in the solicitation and statement of work.

• Which NAICS codes commonly align with A‑E work for buildings?

  • Common A‑E classifications include Architectural Services (541310) and Engineering Services (541330). Historical federal guidance has associated these NAICS with A‑E examples for building projects, illustrating typical classification patterns for design-focused requirements. ²

• Where is the PSC captured in federal reporting, and is it visible in SAM.gov?

  • PSC is required in FPDS award reporting as data element 8A (“Product or Service Code”). In practice, PSC selections flow from contracting documentation into reporting systems. SAM.gov help materials also reference searching opportunities by NAICS or PSC, aiding market research and vendor discovery. ³
