PSC C1JA

Overview

The Product Service Code (PSC) is a governmentwide taxonomy the U.S. federal government uses to classify what is being purchased so spending can be tracked, analyzed, and reported. PSCs are captured on contract actions in FPDS and governed through the PSC Manual maintained on Acquisition.gov. ¹

PSC C1JA identifies architect-and-engineer (A-E) services in support of construction for museums and exhibition buildings. Agencies use C1JA on contract actions where the predominant requirement is A-E for constructing these facilities; related life-cycle activities (construction, operations, maintenance, repair/alteration, leasing) have distinct companion PSCs. ¹

What this PSC covers

• A-E services to support construction of museum and exhibition buildings. ¹
• Use when the principal requirement is A-E design or related services tied to constructing museum/exhibit facilities; the actual building construction is coded under Y1JA. ¹
• Not for operations; operations of museum/exhibit buildings use M1JA. ¹
• Not for routine maintenance or repair/alteration; use Z1JA for maintenance and Z2JA for repair/alteration. ¹
• Not for lease/rental of facilities; lease/rental uses X1JA. ¹
• Not for exhibit design that is not a building (e.g., portable or stand-alone exhibits); use C1PB. ¹
• Additional inclusions/exclusions beyond the descriptor: Not specified by official sources. ²

Related NAICS and PSC codes

Per PSC Manual definitions. ¹

Lifecycle companion PSCs for museum/exhibit facilities

• Purchase of completed museum/exhibit buildings: E1JA. ¹
• Lease/Rental of museum/exhibit buildings: X1JA. ¹
• Construction (new work): Y1JA. ¹
• Maintenance (recurring): Z1JA. ¹
• Repair or Alteration (non-recurring improvements): Z2JA. ¹
• Operations (facility operations services): M1JA. ¹

FPDS coding notes (selection logic)

• PSC reflects the predominant product or service of the action; choose the code that best matches the principal purpose of the buy. ¹
• Environmental attributes, when applicable, are reported separately in FPDS element 8L; building-related services may be marked “environmentally preferable,” per manual guidance. ¹

Frequently asked questions

• What is PSC C1JA?

  • It is the PSC for architect-and-engineer services supporting construction of museums and exhibition buildings. It is distinct from construction, maintenance, and operations codes for the same facility type. ¹

• How does C1JA differ from Y1JA or Z2JA?

  • C1JA covers A-E services tied to construction; Y1JA is used for the construction itself; Z2JA is for repair or alteration work after construction. Each represents a different life-cycle phase. ¹

• Are specific NAICS codes mandated for C1JA?

  • NAICS selection and the applicable size standard are identified in the solicitation; PSC does not set the NAICS. FAR 52.204-8 requires the NAICS and size standard to be stated in the solicitation. ³

• Does the PSC Manual list detailed includes/excludes for C1JA?

  • The manual provides the descriptor “Architect and Engineering- Construction: Museums and Exhibition Buildings” but does not enumerate additional includes/excludes for this code. Not specified by official sources. ²

• Are environmental attributes reported for C1JA actions?

  • FPDS collects environmental attributes in data element 8L. For services, agencies may indicate “environmentally preferable” where appropriate; the manual provides definitions and examples for reporting. ¹
