Jacobs Engineering Group Inc., Pasadena, Calif., has signed a contract with Amtrak to provide program-management and construction-management services for more than 100 infrastructure improvement projects at over 360 locations across the U.S. The contract could possibly exceed $560 million and is being funded through the American Recovery and Reinvestment Act. Jacobs will oversee in part or in full the design and construction of projects such as maintenance facility upgrades, bridge replacements, track work, security enhancements and station improvements. Amtrak spokesman Steve Kulm says the contract, which does not include “higher-speed” corridors, calls for all projects to be completed by Feb. 17, 2011.
