PSC C1DA

Overview

The Product Service Code (PSC) is a governmentwide taxonomy that classifies the products and services the U.S. federal government buys, enabling consistent reporting, analysis, and visibility of contracting spend. PSCs are maintained through the Product and Service Codes Manual and are used in systems such as the Federal Procurement Data System (FPDS) to record “what” was purchased on each contract action. ¹

PSC C1DA is defined in the PSC Manual under Category C1 (Architect and Engineering – Construction) as “Architect and Engineering – Construction: Hospitals and Infirmaries.” Agencies use this code when the principal purpose of the action is architect‑engineer services associated with constructing hospital or infirmary facilities. ¹

• G2X — PSC Y1DA (Construction of Hospitals and Infirmaries)
• G2X — PSC Z2DA (Repair or Alteration of Hospitals and Infirmaries)

What this PSC covers

• Architect and engineering services for the construction of hospital and infirmary facilities, as categorized under C1 Architect and Engineering – Construction. ¹
• Hospital/infirmary facility type specifically, distinct from laboratories and clinics (C1DB) and other hospital buildings (C1DZ). ¹
• Use with A‑E efforts tied to construction; construction execution itself is typically coded under Y1DA, and repair/alteration work under Z2DA. ¹
• Lease/rental of hospital or infirmary facilities is represented separately by X1DA. ¹
• Detailed inclusions, exclusions, deliverables, or required disciplines beyond the title are not specified by official sources. ²

Coding notes from the PSC Manual

• One PSC is reported per FPDS contract action; select the code based on the predominant product or service acquired for that action. ¹
• PSC C1 (including C1DA) reflects architect‑engineer services for construction; Category C2 covers architect‑engineer “General” services not tied to construction (e.g., C211–C223). ¹
• Environmental attributes are recorded separately in FPDS (data element 8L) and do not change the PSC selection. ¹

Frequently asked questions

• What does PSC C1DA mean?
  C1DA is the PSC for architect and engineering services associated with construction of hospitals and infirmaries. It sits within Category C1 (Architect and Engineering – Construction) and is used when the primary purpose is A‑E work for these healthcare facilities. ¹

• How is C1DA different from Y1DA and Z2DA?
  C1DA covers A‑E services tied to construction. Y1DA covers the construction of hospitals/infirmaries, while Z2DA covers repair or alteration of those facilities. These are separate PSCs for distinct lifecycle phases. ¹

• Does C1DA mandate specific NAICS codes?
  No. PSC and NAICS are separate data elements; agencies identify the applicable PSC and NAICS independently for each action. DFARS PGI guidance shows PSC (Block 7b) and NAICS (Block 7c) captured separately for acquisition planning and reporting. ³

• Are detailed inclusions or exclusions for C1DA (e.g., deliverables, disciplines) defined?
  Not specified by official sources beyond the title and category placement in the PSC Manual. Adjacent facility types such as C1DB and C1DZ, and related lifecycle PSCs like Y1DA and Z2DA, are listed separately. ²

• Is C1DA limited to healthcare‑focused agencies?
  No. PSCs are governmentwide classification codes and are used by any awarding agency when applicable, with reporting in FPDS based on the predominant product or service. ¹
