Contracts

Time and Materials(T&M)

A contract type where the government pays for labor at fixed hourly rates and materials at cost, with a ceiling on total obligation.

Overview

A Time and Materials (T&M) contract compensates the contractor based on actual labor hours at specified hourly rates plus the cost of materials. A ceiling price limits the government's total obligation. T&M contracts transfer cost risk to the government because the final price depends on actual hours and materials used. They are used when scope cannot be defined sufficiently for a fixed-price contract.

Why It Matters in GovCon

T&M contracts offer flexibility when requirements are uncertain but carry oversight burden for the government. FAR restricts T&M use — it is appropriate only when no other contract type is suitable. Proposals must include labor categories, hourly rates, and material handling. Contractors must maintain timekeeping and documentation to support billing.

Key Details

  • Labor Rates: Each labor category has a fixed hourly rate including burden; no separate fee on labor.
  • Materials: Reimbursed at cost; may include a materials handling fee (typically a few percent).
  • Ceiling: The contract specifies a ceiling price that cannot be exceeded without modification.
  • FAR 16.601: T&M contracts require a ceiling and adequate government surveillance.
  • Restrictions: Cannot be used when work can be defined for fixed price; inappropriate for long-term or large acquisitions.
  • Audit: Timekeeping and materials documentation are subject to audit.
