FAR 47.305-15—Loading responsibilities of contractors.
Plain-English Summary
FAR 47.305-15 addresses who is responsible for loading, blocking, and bracing rail shipments and when the government must require special shipment instructions in solicitations and contracts. It covers two main topics: first, the contractor’s duty to load carload shipments in accordance with standards published by the Association of American Railroads (AAR); and second, the contracting officer’s duty to include the clause at 52.247-58 when supplies may move in rail carload lots. It also covers the separate situation where the supplies, safety concerns, environmental concerns, or transportability issues require special securing methods or a special mode or vehicle, in which case the solicitation must include detailed specifications coordinated with the transportation office. In practice, this section is about preventing damage, accidents, and shipping disputes by making sure rail freight is properly prepared and that unusual shipment requirements are clearly written into the procurement up front. It matters to both contractors and contracting officers because it allocates responsibility for safe rail loading and ensures the contract documents match the actual transportation needs of the supplies.
Key Rules
Contractor loads rail shipments
Contractors are responsible for loading, blocking, and bracing carload shipments in accordance with the standards published by the Association of American Railroads. This means the contractor must follow the applicable rail freight securing standards rather than relying on informal or ad hoc methods.
Include rail loading clause
When supplies may be shipped in carload lots by rail, the contracting officer must insert the clause at 52.247-58, Loading, Blocking, and Bracing of Freight Car Shipments. The clause puts the loading responsibility and related expectations into the contract.
Use detailed specs for special needs
If the supplies or shipment conditions require special securing methods because of safety, environmental, or transportability factors, the contracting officer must include detailed specifications in the solicitation. Those specifications must be coordinated with the transportation office.
Special mode or vehicle requirements
If only a special mode of transportation or a particular type of vehicle is appropriate, the solicitation must clearly state that requirement. This ensures offerors understand the actual shipping constraints before pricing and performance begin.
Responsibilities
Contractor
Load, block, and brace carload rail shipments in accordance with AAR standards and comply with any special securing methods or transportation requirements stated in the contract.
Contracting Officer
Insert clause 52.247-58 when supplies may be shipped in carload lots by rail, and include detailed, transportation-office-coordinated specifications when special securing methods or special transportation modes/vehicles are required.
Transportation Office
Coordinate on detailed shipment specifications when special methods, safety considerations, environmental concerns, or transportability issues require more than standard rail loading practices.
Practical Implications
Contractors should expect to bear the operational burden for proper rail loading unless the solicitation says otherwise, so they need to know and follow the applicable AAR standards.
Contracting officers should identify rail shipment potential early; if carload rail shipping is possible, the clause must be included at solicitation and contract stage, not added later as an afterthought.
If the item is unusually heavy, fragile, hazardous, oversized, or otherwise transportability-sensitive, standard loading language may be insufficient and detailed specs are needed to avoid damage or safety incidents.
A common pitfall is assuming generic freight language covers special securing needs; this section requires tailored instructions when the shipment’s characteristics demand them.
Failure to coordinate with the transportation office can lead to incomplete or impractical shipment requirements, disputes over responsibility, and increased risk of cargo damage or transportation delays.
