PSC M1BC

Overview

The Product Service Code (PSC) system standardizes classification of goods and services used across U.S. federal procurement records. PSC codes are the primary labels in FPDS and SAM award and opportunity records that describe what the government is buying; the PSC Manual on Acquisition.gov is the authoritative maintenance and guidance source for the codes. ¹

PSC code M1BC is a facility-based operation code used to identify contracts that provide continuous operational support for radar and navigational facilities. Typical assignments include watch‑standing, real‑time signal collection and distribution, control‑room operations, and coordination with air/space traffic or mission control; agencies commonly apply M1BC to task orders and service contracts where operation — not repair or procurement — is the primary deliverable. ²

What this PSC covers

• Operation of radar stations and surveillance arrays, including watch‑standing and systems monitoring.
• Operation of navigational aids, beaconing systems, and associated control‑room functions for air, maritime, or space facilities.
• Real‑time signal and telemetry collection, processing, formatting, and distribution to downstream consumers.
• On‑site operational staffing, shift scheduling, continuity of operations, and readiness reporting.
• Coordination with air/space traffic control, mission control centers, and other operational stakeholders for reporting and tasking.
• Facility access coordination and operational security activities directly tied to continuous operation.

Related NAICS and PSC codes

The Z‑series PSCs (for example, Z1BC) cover maintenance and repair activities that are distinct from operational services captured by M1BC. NAICS classifications such as 517810 may appear on solicitations or awards when the underlying industry sector aligns with telecommunications or signal‑processing support, but NAICS and PSC serve different reporting roles (industry vs. product/service).

How agencies typically record and use M1BC

Agencies tag operational contracts and task orders with M1BC when the contract’s primary deliverable is the continuous operation, monitoring, or watch‑standing of radar or navigation sites. DoD organizations and civilian agencies have used this PSC for perimeter radar operations, air‑traffic facility operations, telemetry/range support, and comparable mission‑operations tasking; FPDS award records illustrate common agency practice. ²

Frequently asked questions

• Q: Which procurements use PSC M1BC?
  A: Contracts funding ongoing operation, monitoring, or watch‑standing of radar and navigational facilities are commonly coded as M1BC. Typical examples in FPDS include DoD and civilian operational support task orders that deliver continuous facility operations and personnel services. ²

• Q: Does M1BC cover repairs and equipment maintenance?
  A: No. Maintenance and repair activities are normally reported under maintenance PSCs (Z‑series); the PSC Manual separates operation (M‑series) from maintenance (Z‑series), so routine sustainment or depot repair is generally not coded as M1BC. ¹

• Q: How should contracting officers decide when to use M1BC in FPDS/SAM?
  A: Use M1BC when the primary contract deliverable is facility operation (personnel/operations services) rather than equipment acquisition or standalone maintenance. If the contract’s primary purpose is sustainment/repair, select the appropriate Z‑series maintenance PSC instead. ²
