PSC C1HA

Overview

The federal Product and Service Code (PSC) system categorizes what the U.S. government buys so agencies can track, analyze, and report spending across procurement systems. PSCs are reported on contract actions to indicate “what was bought” and are governed by the Product and Service Codes Manual maintained on Acquisition.gov. ¹
PSC C1HA identifies architect-and-engineer (A/E) services related to construction for Government‑Owned, Contractor‑Operated (GOCO) research and development facilities. It is applied when the predominant requirement is A/E–construction scope (for example, planning, design, and related professional services) for GOCO R&D facilities, as distinguished from construction execution or other lifecycle activities coded elsewhere. ¹

What this PSC covers

• Facility planning, programming, and design services for GOCO R&D campuses and buildings where A/E–construction scope is the predominant requirement. ¹
• Multidisciplinary architectural and engineering design deliverables (drawings, specifications) across structural, mechanical, electrical, and fire protection systems. ³
• Geotechnical studies, surveying, and mapping that are incidental to and integrated with real property design activities. ³
• Cost estimating, value engineering, and other professional A/E services performed in support of construction documents. ³
• Construction‑phase A/E services such as submittal reviews and site visits associated with GOCO R&D facility projects. ³
• Use C1HB when the facility is Government‑Owned, Government‑Operated (GOGO) rather than GOCO; use Y1HA, Z1HA, or Z2HA when construction, maintenance, or repair/alteration is the predominant need. ¹

Acquisition method for C1HA-coded work

A/E services are acquired under Qualifications‑Based Selection (Brooks Act), with public announcement (for example, SF 330), evaluation of qualifications, and negotiation with the most highly qualified firm. When A/E services predominate—even alongside other services—the procedures in FAR Subpart 36.6 apply. ⁴

Frequently asked questions

• What does PSC C1HA signify?
  It denotes architect‑and‑engineering services related to construction for Government‑Owned, Contractor‑Operated research and development facilities. It is part of the Category C (A/E Services) family and specifically the C1 (A/E–Construction) series. ¹

• When should C1HA be used instead of Y1HA?
  Use C1HA when the requirement is for A/E professional services tied to construction (planning, design, incidental services). Use Y1HA when the requirement is construction execution. Both are distinct codes within the PSC Manual. ¹

• How are architect‑engineer services under C1HA procured?
  Agencies follow FAR Subpart 36.6 (Brooks Act), announcing requirements, evaluating SF 330 qualifications, and negotiating with the top‑ranked firm at fair and reasonable prices. ⁴

• Which NAICS codes are prescribed for C1HA?
  The PSC Manual defines PSCs but does not prescribe specific NAICS codes for each PSC. Not specified by official sources ⁶.

• What is a GOCO R&D facility in this context?
  GOCO refers to facilities owned by the federal government but operated by a contractor, a model widely used for Department of Energy national laboratories. This context explains the GOCO designation within C1HA. ⁵
