The Transportation Security Administration (TSA) has awarded Siemens [SI] a potential $468.6 million contract through Feb. 2014 to maintain an Integrated Logistics Support program to sustain the agency’s security equipment–excluding Explosives Detection Systems–at the nation’s Category IV through Category X airports. The base period of the contract runs until Jan. 31, 2010, and then contains four one-year options. Siemens has been doing the maintenance work on checkpoint X-Ray systems, explosive trace detectors, and walk-through portal screening systems since March 2005 when it unseated Boeing [BA], which had been doing the work since June 2002 (TR2, March 9, 2005). Siemens has received about $530 million under its original contract. Some of those funds include work the company will be continuing under an extension that runs into Feb. 2010 for warehousing. The new contract doesn’t include the warehousing work, which will be competed as a small business set aside for an award early next year. Other work Siemens will be doing under the new contract, which goes into effect Sept. 30, is program management, performance based logistics services, TSA Service Response Center services, and associated information technology infrastructure.
