    FAR 42.505—Postaward subcontractor conferences.

    Plain-English Summary

    FAR 42.505 addresses postaward subcontractor conferences and explains who is responsible for them, when the Government may participate, and the limits on Government involvement. It covers the prime contractor’s general duty to conduct these conferences, the ability of the prime contractor to invite Government representatives, the Government’s ability to request that a conference be initiated, and the need to include representatives from the relevant contract administration offices. It also sets strict boundaries for Government representatives by requiring recognition of the lack of privity between the Government and subcontractors, prohibiting actions that would alter or conflict with subcontract terms, and requiring that any direction or commitment affecting the prime contract or contractor be issued in writing by the contracting officer under the procedures of FAR 42.503-2. In practice, this section is meant to support coordination and communication without allowing the Government to bypass the prime contractor or create unauthorized obligations with subcontractors. It helps prevent confusion over authority, protects subcontract integrity, and ensures that any Government-driven changes are properly documented and routed through the contracting officer.

    Key Rules

    Prime leads subcontract conferences

    The prime contractor is generally responsible for conducting postaward conferences with subcontractors. This means the prime manages the meeting, agenda, and coordination unless the Government requests involvement.

    Government may participate by invitation

    The prime contractor may invite Government representatives to a subcontractor conference, and the Government may also request that the prime initiate one. Participation is therefore possible, but it is not a substitute for the prime’s responsibility to manage subcontractor communications.

    Invite contract administration offices

    The prime contractor should ensure that representatives from the involved contract administration offices are invited. This helps align the conference with the offices responsible for contract oversight and administration.

    No privity with subcontractors

    Government representatives must recognize that there is no privity of contract between the Government and subcontractors. As a result, they cannot treat subcontractors as if they were direct contractual counterparts to the Government.

    No inconsistent subcontract action

    Government representatives shall not take action that is inconsistent with or alters subcontracts. They may discuss issues, but they cannot direct changes that would modify subcontract terms or obligations outside proper channels.

    Written CO direction required

    Any change in direction or commitment affecting the prime contract or contractor that results from a subcontractor conference must be issued as written direction from the contracting officer to the prime contractor, following FAR 42.503-2. Oral understandings or informal commitments are not enough.

    Responsibilities

    Prime Contractor

    Generally conduct postaward conferences with subcontractors; invite Government representatives when appropriate; ensure representatives from involved contract administration offices are invited; manage subcontractor communications so that Government participation does not create unauthorized commitments or subcontract changes.

    Government Representatives

    Participate only within the limits of their authority; recognize the lack of privity with subcontractors; avoid actions that conflict with or alter subcontract terms; ensure any resulting direction or commitment affecting the prime contract or contractor is routed through the contracting officer in writing.

    Contracting Officer

    Issue any required changes in direction or commitments in writing to the prime contractor, using the process described in FAR 42.503-2; ensure that Government communications arising from the conference are properly authorized and documented.

    Contract Administration Offices

    Participate when invited and provide relevant administrative oversight or input related to the prime contract and associated subcontract performance issues.

    Practical Implications

    1

    This section keeps subcontractor conferences from becoming a backdoor way for the Government to direct subcontractors directly. Contractors should treat Government attendance as advisory/coordination support, not as a source of binding instructions to subs.

    2

    A common pitfall is informal Government guidance given during a conference that sounds like a directive. If it affects the prime contract or contractor, it must be converted into written contracting officer direction to the prime.

    3

    Prime contractors should be careful to invite the right contract administration personnel, especially when subcontract performance issues could affect schedule, quality, or compliance.

    4

    Government personnel should avoid language that could be interpreted as changing subcontract requirements or creating commitments to subcontractors, since that can lead to disputes or unauthorized commitments.

    5

    When a conference surfaces a needed change, the safe practice is to document the issue, route it through the prime contractor, and obtain formal written CO action rather than relying on meeting notes or verbal agreement.

    Official Regulatory Text

    (a) The prime contractor is generally responsible for conducting postaward conferences with subcontractors. However, the prime contractor may invite Government representatives to a conference with subcontractors, or the Government may request that the prime contractor initiate a conference with subcontractors. The prime contractor should ensure that representatives from involved contract administration offices are invited. (b) Government representatives- (1) Must recognize the lack of privity of contract between the Government and subcontractors; (2) Shall not take action that is inconsistent with or alters subcontracts; and (3) Shall ensure that any changes in direction or commitment affecting the prime contract or contractor resulting from a subcontractor conference are made by written direction of the contracting officer to the prime contractor in the same manner as described in 42.503-2 .
