NASA awarded Computer Sciences Corp. [CSC] a $30.4 million contract extension for work at Johnson Space Center, and options may bolster that to $55.4 million, adding to what may total $342.8 million thus far.

CSC will work on the Center Operations Support Services contract.

The new order, which begins April 1, has a base period of six months followed by five one-month options.

It extends a CSC Applied Technology Division contract.

Exercise of the five one-month options would bring the total potential value to $55.4 million for this latest installment.

CSC has held the contract for five years. The six-month extension and the options would bring the total value of the contract to $342.8 million throughout the nearly six-year period.

The contract includes operations support activities at Johnson’s Sonny Carter Training Facility and Ellington Field. It involves support in maintenance and operations, grounds, custodial, transportation, logistics, property and equipment, construction, engineering and environmental areas.

Major subcontractors include Anadarko Industries, LLC, of Houston and Lynx, Ltd., of Las Cruces, N.M.
