Reston-based contractor Serco last week made leadership changes, bringing in new executives from contracting giants Science Applications International Corp. and Computer Sciences Corp.

The company named Gary Shankman, formerly chief financial officer of SAIC’s defense solutions group, to serve as its CFO. Chris Sullivan, former chief information officer of CSC’s North American Public Sector, was named CIO.

Both SAIC and CSC have been making significant organizational changes — SAIC to prepare for a split of its company and CSC to reverse serious financial losses.

Serco also appointed Candy Curtin senior vice president of its human resources department and Jim Orndorff vice president of Serco’s intelligence business unit. Curtin had been interim head of the human resources department for the past year and has been with Serco for more than 12 years.

Orndorff joins from SAIC, where he was senior vice president and chief technology officer for the company’s cyber and intelligence business areas.

SRA cries foul in Army award

The Government Accountability Office last month denied a protest filed by Fairfax-based SRA International against an Army contract awarded to McLean-based Science Applications International Corp.

SRA’s proposal had been deemed technically unacceptable to win the contract — which provides technology operations and security services for the National Guard Bureau — because its facility plan did not meet minimum antiterrorism standards, creating what the government deemed a “significant risk,” according to the GAO decision. Though both companies had offered discounted rates from the fixed contract vehicle price, SAIC offered deeper discounts, the report added.

In its protest, SRA refuted the judgment about its facility and challenged the price SAIC offered.

GAO rejects Agile Defense protest

The GAO also shot down a protest filed by Fairfax-based Agile Defense against an Air Force award to Rockville-based Federal IT Consulting for executive airlift communications network support services.

The decision, made in November but released last month, rejected Agile’s “numerous arguments” that the Air Force erred in its decision. In particular, the Air Force found that Agile’s proposal did not provide enough personnel to meet the requirement for around-the-clock staffing at Joint Base Andrews.

“We have considered all of Agile’s arguments and find that the Air Force reasonably concluded that Agile failed to provide adequate staffing to meet the requirement,” the GAO wrote.
