1.0 SCOPE and BACKGROUND

Naval Facilities Engineering and Expeditionary Warfare Center (NAVFAC EXWC) has a requirement to replace an aging fleet of trailers based on current mission and support requirements. NAVFAC EXWC has documented requirements to address shortcomings of the current fleet that at a minimum comply with Military (MIL) and Society of American Engineer (SAE) standards for tactical and commercial trailers. Compliance to these government and non-government standards introduces commonality with other military, Department of Defense (DOD), and civilian trailers, allowing fleet and joint operations to utilize the capabilities to their fullest. The trailers will also support operational readiness and functionality in austere conditions.

Engineering structural analysis.

Prior to all testing, the OEM Vendor/contractor may provide dimensional and material design data on the provisions and their surrounding structure. This data will be used to perform a structural analysis of the provisions. In lieu of providing the required design information, the contractor can perform a structural analysis and provide the results of the analysis for review and concurrence.

Either the required data or the contractor's structural analysis results should be provided at least 90 days prior to scheduled provision testing. The purpose of the structural analysis is to assess the risk of testing, thereby reducing the number of failures or possibly eliminating the test in acceptable cases. This will result in lower overall acquisition costs to materiel developers.

Removal or relocation of mechanically attached (non-welded, non-riveted, etc.) components with common tools, requiring not more than 1 man-hour total to remove, relocate and tie down, and not more than 1 man-hour total to return the vehicle to its original, as opposed to reduced, configuration; shall be acceptable.

a. The self-mobility of the vehicle shall not be affected by reducing its configuration. Tie downs for removed or relocated equipment shall be furnished.

b. For Trailers, the rated capacity of the axles and suspension system shall be not less than 1.25 times the load imposed on each by the curb weight of the trailer.

c. The vehicle shall be transportable as described above without any other special provisions and without any shoring unless unavoidable without significant alteration to the vehicle.

d. The vehicle shall not be delivered to the Government in its reduced configuration.
