PSC Z1BA

Overview

The Product Service Code (PSC) system is a four‑character taxonomy used across U.S. federal procurement to classify the specific products and services purchased by agencies. PSCs are the principal coding element in FPDS and SAM reporting, support spend analysis and category‑management alignment, and are maintained via the governmentwide PSC management process and manual.¹

PSC Z1BA — Maintenance of Air Traffic Control Towers — is the PSC label used to report contract actions whose predominant effort is the maintenance of air traffic control tower facilities. Official FPDS records show Z1BA applied to FAA and other agency actions for tower‑related maintenance and sustainment work; task‑level detail beyond the PSC label is recorded through contract descriptions, line items, and award records rather than a separate public code definition document.²

What this PSC covers

• Air traffic control tower facility maintenance
• Tower structural upkeep and exterior repairs
• Interior facility maintenance and finishes
• Building systems (electrical, lighting, HVAC) serving towers
• Support for tower‑related facilities sustainment

Detailed task‑level inclusions and exclusions are defined in solicitation documents and contract line items; the PSC label itself is a reporting classification. Not specified by official sources ³.

Related NAICS and PSC codes

Type	Code	Descriptor
PSC	Z1BA	Maintenance of Air Traffic Control Towers
PSC	Z2BA	Repair or Alteration of Air Traffic Control Towers
PSC	Z1BC	Maintenance of Radar and Navigational Facilities
NAICS	236220	Commercial and Institutional Building Construction

Mappings between Z1BA and specific NAICS codes are determined by the procuring agency at award level and are reflected in FPDS award records.²

Reporting and usage context

Agencies record PSCs on FPDS data elements to indicate the predominant product or service procured; PSC Z1BA is used where tower maintenance represents the primary effort reported on a contract line or award. The PSC label informs spend analysis, category‑management alignment, and reporting but does not by itself prescribe technical requirements or standards for tower maintenance — those appear in solicitations, statements of work, and agency‑specific facility standards.²

Frequently asked questions

• Q: What specific tasks are required under PSC Z1BA?

  • A: The PSC is a reporting classification and does not list line‑item tasks. Specific tasks (structural repair, HVAC service, electrical work, etc.) are defined in the solicitation statement of work or task order; the PSC identifies the predominant category of the award. Not specified by official sources ³.

• Q: Which NAICS codes commonly appear with Z1BA awards?

  • A: FPDS award records commonly pair tower maintenance PSCs with construction and building NAICS codes such as 236220 (Commercial and Institutional Building Construction); the exact NAICS selection depends on the nature of the work defined in the solicitation and award documents.²

• Q: Where can I find authoritative PSC lists and current code status?

  • A: Governmentwide PSC resources, the PSC Manual and updates, and the official PSC selection tools are the authoritative sources for current PSC lists and status; contracting professionals commonly use the PSC Tool and FPDS for code selection and verification.¹

• Q: Does Z1BA include maintenance of tower‑mounted navigational or electronic equipment?

  • A: Z1BA refers to maintenance of the tower facility itself. Maintenance of specialized navigational or electronic equipment may be reported under other PSCs (for example, Z1BC for radar / navigational facilities) depending on the predominant effort and how contract line items are defined.²
