PSC N028

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies goods and services for procurement reporting in systems such as FPDS and SAM; the PSC Manual on Acquisition.gov is the official source for PSC entries and guidance.¹

PSC N028 — Installation of Equipment- Engines, Turbines, and Components identifies acquisitions for on-site placement, mechanical mounting, setup, or reinstallation of engines, turbines, and their components. The PSC Manual records the entry title and category but does not provide task-level definitions or an exhaustive scope; contracting documents and statements of work define detailed requirements for specific procurements.¹

Observed FPDS pairings (optional)

FPDS award records show practical pairings where PSC N028 appears alongside construction and mechanical industry NAICS such as NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors). These FPDS examples reflect how agencies report awarded actions and do not constitute a prescriptive crosswalk in the PSC Manual.²

Frequently asked questions

• What exactly is a PSC and where is it used?
  A PSC is a four-character code used to classify products and services reported in federal procurement systems (FPDS, SAM). The PSC Manual on Acquisition.gov provides the official list of PSC entries and is the controlling reference for PSC assignments.¹

• What does PSC N028 cover in practice?
  PSC N028 names installations involving engines, turbines, and their components. The manual entry is a title-level classification; contract SOWs/specifications define the detailed scope and tasks for each procurement.¹

• Which agencies commonly use PSC N028?
  FPDS records indicate use by Department of Defense civil engineering and facility organizations (for example NAVFAC) and other agencies when contracting installation or reinstallation of engines and turbines in facilities or systems.²

• How do NAICS and PSC relate for a single requirement?
  PSC and NAICS serve complementary reporting roles: PSC classifies the product or service type while NAICS identifies the industry or business activity. The PSC Manual does not mandate a single PSC→NAICS mapping; award records in FPDS show commonly observed pairings such as NAICS 238220 with PSC N028 as practical examples.¹
