PSC Z1AB

Overview

The Product Service Code (PSC) system is a governmentwide taxonomy used to classify goods and services procured by the U.S. federal government for reporting, analysis, and contract management; PSC entries are recorded in FPDS/SAM and are governed by the PSC Manual maintained on acquisition.gov. ¹

The PSC entry Z1AB — Maintenance of Conference Space and Facilities — appears in the PSC Manual under Category Z (Maintenance, Repair, Alteration of Structures/Facilities) and is listed as a service-code category within the Z1 family. The manual provides the code label and its placement but does not supply an expanded task list or detailed scope for the entry; therefore specific inclusions and exclusions are not defined in the published manual. ¹

What this PSC covers

• Maintenance of conference space and facilities — label as listed in the PSC Manual. ¹
• Building-systems upkeep associated with conference spaces — Not specified by official sources. ¹
• Interior facility services for meeting/auditorium areas (for example, lighting and seating upkeep) — Not specified by official sources. ¹
• Preventive maintenance and routine facility inspections for conference-related spaces — Not specified by official sources. ¹
• Ancillary support areas related to conference functions (lobbies, breakout rooms) — Not specified by official sources. ¹

Related NAICS and PSC codes

Official PSC-to-NAICS crosswalk entries and detailed NAICS pairings for Z1AB are maintained in the PSC Manual spreadsheets; the manual text does not present a single canonical NAICS mapping for every PSC entry, and the printed code list omits detailed crosswalk rows for some service codes. For neighboring PSC entries, the manual lists related codes such as Z2AB (Repair or Alteration of Conference Space and Facilities) and X1AB (Lease/Rental of Conference Space and Facilities). Not specified by official sources for a single canonical NAICS mapping in the main manual text. ¹

Acquisition notes

• Selection rule: PSC codes should reflect the predominant product or service for the contract action; use the code that represents the principal effort when multiple goods or services are present in a single award. This FPDS guidance applies when determining whether to report Z1AB for a procurement whose primary effort is conference-space maintenance. ¹
• Distinction from adjacent PSCs: Z1AB (maintenance) is listed separately from Z2AB (repair/alteration) and X1AB (lease/rental), indicating different procurement intents; the PSC Manual organizes these as distinct service-code entries. ¹

Frequently asked questions

• Q: When is Z1AB appropriate instead of Z2AB or X1AB?
  A: Use Z1AB when maintenance activities are the primary contract requirement; choose Z2AB for repair or alteration projects and X1AB for lease or rental of conference space. The manual distinguishes these as separate PSC entries. ¹

• Q: Does the PSC Manual define specific tasks included under Z1AB?
  A: The manual lists the code title but does not provide an itemized task list or explicit inclusion/exclusion criteria for the code; detailed activities are not specified by the published manual. ¹

• Q: How should an acquisition with mixed facility work (conference rooms plus offices) be coded?
  A: FPDS/PSC guidance requires reporting the predominant product or service. If conference-space maintenance represents the primary scope and dollar value, report Z1AB; otherwise select the PSC that reflects the dominant work. ¹
