PSC Z1DA

Overview

The Product Service Code (PSC) system is the federal government’s standardized taxonomy for categorizing goods and services procured through contracts and task orders. PSC codes are recorded in procurement records (FPDS and SAM) to enable consistent tracking, reporting, and analysis of government spending; the PSC Manual documents the codes, labels, and management guidance for code selection and maintenance. The code Z1DA is in Category Z (Maintenance, Repair, Alteration of Structures/Facilities), under Z1 (Maintenance of Structures and Facilities), and is titled “Maintenance of Hospitals and Infirmaries.” The PSC Manual is the authoritative source for the code name and placement in the Z1 family.¹

Coding guidance (optional)

• Select the PSC that describes the predominant service or product on the contract action; PSC is entered in FPDS data element 8A. The PSC Manual emphasizes choosing the code that best represents the “what” purchased when multiple products/services appear on an action.¹
• PSCs are mapped into government-wide spend categories for category management; facility- and construction-related PSCs reside in the Facilities & Construction government-wide category. For category-level alignment and mapping details, consult the Government‑wide PSC Category Alignment materials.³

Frequently asked questions

• How should an acquisition team decide when to use Z1DA versus Z2DA?

  Choose the code that reflects the predominant contract objective: Z1DA is a maintenance code while Z2DA covers repair or alteration actions. Assign the PSC that best matches the primary work and dollar value recorded in FPDS element 8A, per PSC Manual guidance.¹

• Which federal systems report and surface contract actions using PSCs like Z1DA?

  Contract actions and awards that include PSCs are reported in FPDS and are searchable in SAM.gov contract data. SAM.gov provides help pages explaining how to search and filter by PSC or NAICS for notices and awards.²

• Are there standard NAICS codes tied to Z1DA?

  The PSC Manual lists PSCs and descriptors but does not prescribe a single NAICS mapping for Z1DA; NAICS selection is case specific and shown on individual solicitations and awards. Not specified by official sources ¹.

• Can a single contract include Z1DA and other PSCs?

  Yes. Contracts often include multiple products and services; agencies should assign the PSC that represents the predominant product or service dollar value for the action, per the PSC Manual.¹
