Computer Sciences Corp. has started working again on the $628 million Air Force Expeditionary Combat Support System task order awarded in September 2006.

A protest over the award by IBM Global Service in November 2006 halted the work. The Government Accountability Office recently upheld the Air Force’s selection of CSC to furnish information technology services to help the Air Force upgrade its global supply chain.

GAO informed the integrator of its decision to reject the IBM protest on March 1, said Caroline Longanecker, a CSC spokeswoman.

Under the task order, CSC will provide business process redesign for logistics and a commercial enterprise resource planning implementation.

The ERP implementation seeks to merge base level and wholesale logistics systems and deliver substantial net-savings to the Air Force, according to DOD.

The ECSS Program Office in the 754th Electronic Systems Group will manage the work in collaboration with the Air Force Logistics Transformation Office at Wright Patterson Air Force Base, Ohio.

In addition, CSC said it will build a new facility in Greene County, Ohio, that will add more than 400 new full-time jobs.

CSC currently has more than 200 employees at another facility in Greene County for other work with the Air Force.

CSC of El Segundo, Calif., has about 77,000 employees and annual sales of $14.7 billion in 2006. The company ranks No. 5 on Washington Technology’s 2006 Top 100 list of the largest federal IT contractors.
