PSC Y1KF

Overview

The Product Service Code (PSC) is the federal government’s standardized classification system for reporting products and services procured through federal contracts. PSC entries are used in systems such as FPDS and SAM to classify contract spend, enable reporting and analysis, and are maintained and published through the Product and Service Code Manual on Acquisition.gov.¹

PSC Y1KF — Construction Of Dredging Facilities — is the PSC descriptor used to classify contract actions where the predominant work is construction related to dredging facilities. The PSC Manual lists Y1KF as the official code label; the manual does not provide expanded scope language beyond the short descriptor, so additional detail on boundaries or exclusions is not specified by official sources.¹

Federal Register listings identify the broader dredging PSC family (examples: C1KF, M1KF, X1KF, Y1KF, Z1KF, Z2KF) and provide context for lifecycle distinctions among codes.²

Common procurement contexts

Civil works and navigation projects administered by the U.S. Army Corps of Engineers and other civil agencies frequently use Y1KF when the predominant contract deliverable is construction of dredging-related facilities; specific agency coding practice varies by solicitation and should be confirmed in the solicitation notice (agencies assign NAICS and PSC based on the predominant work).¹

Frequently asked questions

• Q: What is the definitive source for the Y1KF descriptor?
  A: The authoritative source is the Product and Service Code Manual on Acquisition.gov; Y1KF is listed there as “CONSTRUCTION OF DREDGING FACILITIES.” See the PSC manual for the official short descriptor.¹

• Q: Which NAICS is typically used with Y1KF?
  A: Agencies commonly pair Y1KF with NAICS 237990 (Other Heavy and Civil Engineering Construction), but the NAICS selected should be confirmed in each solicitation because NAICS assignment depends on the predominant construction work.¹

• Q: Does Y1KF cover maintenance dredging or operation of dredges?
  A: Y1KF’s label denotes construction activities; maintenance and operation are tracked under related PSCs such as Z1KF (maintenance) and M1KF (operation). The Federal Register listings explain the related PSC family distinctions.²
