1.2 FAR Structure, System Architecture & Authority

1.2 FAR Structure, System Architecture & Authority

The Federal Acquisition Regulation (FAR) is the primary regulation used by all executive agencies in their acquisition of supplies and services with appropriated funds. Codified in Title 48 of the Code of Federal Regulations (CFR), Chapter 1, the FAR implements statutory procurement requirements and establishes uniform policies and procedures across the federal government.

Structural Organization of Title 48 CFR

The FAR is structured hierarchically to facilitate navigation across its 53 parts. The overall regulation is divided into 8 Subchapters (Subchapters A through H):

Decimal Numbering Convention

FAR citations follow a precise decimal numbering system. For example, in the citation FAR 1.602-3(c)(1):

• 1 represents the FAR Part (Part 1: Federal Acquisition Regulations System).
• .6 represents the Subpart (Subpart 1.6: Career Development, Contracting Authority, and Responsibilities).
• 02 represents the Section (Section 1.602: Contracting Officers).
• -3 represents the Subsection (Subsection 1.602-3: Ratification of unauthorized commitments).
• (c)(1) indicates paragraph (c) and subparagraph (1).

Agency FAR Supplements & Deviations

Individual executive agencies publish agency supplements to Title 48 CFR to implement agency-unique policies. Agency supplements reside in separate chapters of Title 48 (e.g., Chapter 2 for DFARS, Chapter 5 for GSAM, Chapter 8 for VAAR). Supplements cannot conflict with or weaken base FAR provisions unless a formal FAR Deviation is approved pursuant to FAR Subpart 1.4 (Individual Deviations affect one contract; Class Deviations affect multiple contracts across an agency).

Authority of the Contracting Officer (FAR 1.602)

Under FAR 1.602-1, Contracting Officers (COs) have authority to enter into, administer, or terminate contracts and make related determinations and findings. However, COs bind the Government only to the extent of the authority delegated to them through a formal written warrant (Standard Form 1402, Certificate of Appointment).

Contracting Officer Warrants (FAR 1.603)

Agency Heads select and appoint Contracting Officers based on education, experience, specialized training, and demonstrated business acumen. Warrants establish explicit dollar limits and functional boundaries:

• Micro-purchase Warrants: Limited to transactions at or below the micro-purchase threshold ($15,000 baseline).
• Simplified Acquisition Warrants: Limited to acquisitions up to the simplified acquisition threshold ($350,000 baseline, or up to $15 million for commercial products/services under FAR Subpart 13.5).
• Unlimited Warrants: Permit execution of contracts of any dollar value without ceiling constraints.

Delegable vs. Non-Delegable Authority

Certain statutory powers are vested exclusively in specific senior procurement officials:

• Non-Delegable Duties: Reserved strictly for the Agency Head or Head of Contracting Activity (HCA). Examples include approving class deviations affecting statutory rights, making specific national security determinations, or terminating contracts for convenience in extraordinary high-dollar statutory scenarios.
• Delegable Duties: Tasks that a Contracting Officer may delegate in writing to authorized representatives, such as designating a Contracting Officer's Representative (COR) to monitor technical performance or assigning administrative tasks to an Administrative Contracting Officer (ACO).

Baseline Financial Thresholds

Federal acquisition thresholds are established by statute and periodically adjusted for inflation under 41 U.S.C. 1908. Contracting Officers must apply the following core thresholds:

• Micro-purchase Threshold (MPT): Standard baseline is $15,000 for routine supplies/services. Statutory exceptions include $2,000 for construction (Wage Rate Requirements / Davis-Bacon Act), $2,500 for services (Service Contract Labor Standards), and higher thresholds for contingency operations ($25,000 domestic / $40,000 overseas).
• Simplified Acquisition Threshold (SAT): Standard baseline is $350,000 for routine acquisitions. Enables simplified acquisition procedures under FAR Part 13 and automatic small business set-asides. Commercial item simplified procedures allow up to $15,000,000 under FAR Subpart 13.5. Contingency thresholds expand to $1 million (domestic) and $2 million (overseas).

Unauthorized Commitments & Ratification (FAR 1.602-3)

An unauthorized commitment is defined as an agreement, obligation, or commitment made by a government representative who lacks the legal authority to enter into that agreement on behalf of the Government (e.g., an engineer directing a contractor to perform out-of-scope work without CO approval).

Because unauthorized commitments create non-binding obligations, contractors cannot be paid until the transaction is cured through formal ratification.

Mandatory 7-Part Ratification Criteria (FAR 1.602-3(c))

An unauthorized commitment may be ratified by an authorized ratifying official (typically the Head of the Contracting Activity) only when ALL of the following 7 conditions are satisfied:

1. Benefit Received: Supplies or services have been provided to and accepted by the Government, or the Government otherwise obtained a benefit from performance.
2. Authority Existed: The ratifying official had the authority to enter into a contractual commitment at the time the unauthorized commitment was made and currently possesses that authority.
3. Resulting Contract Proper: The resulting contract would otherwise have been proper if made by an authorized Contracting Officer.
4. Price Fair & Reasonable: The Contracting Officer reviewing the ratification determines the price to be fair and reasonable.
5. CO Recommends & Legal Concurs: The Contracting Officer recommends payment and legal counsel concurs with the legal sufficiency of the ratification.
6. Funds Available: Funds were available at the time the unauthorized commitment was made and remain currently available.
7. Proper Approval: The ratification is formally approved in accordance with agency procedures by the designated ratifying authority (typically the HCA).
