Shohet, 202/366-0652, Contracting Officer Robert Spratling, 202/366-0571 The Federal Railroad Administration (FRA) intends to negotiate on a sole source basis with the Association of American Railroads (AAR), the award of Modification 4 to Task Order No. 102 under subject contract. Subject modification will extend the period of performance an additional 3 years, from February 5, 1995, to March 31, 1998, and provide for an additional 15,500 person hours of effort. The AAR is to provide services in support of the development of experimental design and full scale field tests in the areas of track buckling safety assessments, track resistance characterization, and continuous welded rail technology. The tests are to be performed using the facility for Accelerated Service Testing/High Tonnage Test Loop and other tracks located at the Transportation Test Center (TTC), Pueblo, Colorado. These tests are to be done in conjunction with other tests already under contract with the AAR. The AAR is the only known source capable of meeting all the Government's minimum requirements for this effort. This is not a competitive procurement and no solicitation is available. (0003)
