    FAR 45.501Prime contractor alternate locations.

    Plain-English Summary

    FAR 45.501 addresses how the Government can evaluate a prime contractor’s management of Government property when that property is not physically located at the prime contractor’s own facility. Specifically, it covers the property administrator assigned to the prime contract and that administrator’s ability to request support property administration from another contract administration office. The purpose is to make sure Government property held at subcontractors or other alternate locations is properly accounted for, safeguarded, and managed even when the prime contractor does not directly control the site. In practice, this section recognizes that property oversight may require local or specialized support from another office with access to the location where the property is actually being used or stored. It is a coordination rule, not a substantive property-management standard by itself, but it is important because it helps the Government verify compliance across dispersed supply chains and off-site performance locations.

    Key Rules

    Support may be requested

    The property administrator assigned to the prime contract may ask another contract administration office for support property administration. This is discretionary authority, used when additional help is needed to evaluate the prime contractor’s property management.

    Applies to off-site property

    The support is specifically for property located at subcontractors and other alternate locations. The focus is on Government property that is outside the prime contractor’s immediate premises but still under the prime contractor’s management responsibility.

    Purpose is evaluation

    The requested support is for evaluating the prime contractor’s management of the property. The section is about oversight and assessment, not about transferring ownership or changing the prime contractor’s underlying responsibility for the property.

    Coordination across offices

    The rule contemplates cooperation between the assigned property administrator and another contract administration office. This allows the Government to use the office best positioned to observe or inspect the alternate location.

    Responsibilities

    Property Administrator assigned to the prime contract

    May determine that support is needed and request assistance from another contract administration office to evaluate the prime contractor’s management of Government property at subcontractor or alternate locations.

    Another Contract Administration Office

    Provides support property administration when requested, helping assess the condition, control, accountability, and management of property located away from the prime contractor’s own site.

    Prime Contractor

    Must continue to manage Government property at subcontractors and alternate locations in accordance with contract requirements and be prepared for Government evaluation at those locations.

    Subcontractor or Alternate Location Holder

    Must allow the property oversight process to occur as required by the contract flowdown and site arrangements, including access and information needed for evaluation when applicable.

    Practical Implications

    1

    This section matters when Government property is dispersed across multiple sites, because the assigned property administrator may not be able to verify control and accountability without local support.

    2

    Contractors should expect that property at subcontractors or alternate locations may be reviewed by a different administration office than the one assigned to the prime contract.

    3

    A common pitfall is assuming off-site property is outside Government oversight; it is still subject to evaluation, and weak flowdown controls can create compliance problems.

    4

    Another risk is poor coordination between the prime contractor and subcontractor sites, which can lead to incomplete records, delayed inspections, or unresolved discrepancies.

    5

    For contracting officers and property administrators, the practical takeaway is to plan early for site access, reporting lines, and support administration needs when property will be held away from the prime contractor’s main facility.

    Official Regulatory Text

    The property administrator assigned to the prime contract may request support property administration from another contract administration office, for purposes of evaluating prime contractor management of property located at subcontractors and alternate locations.
