Falls Church-based government contractor DynCorp International said it is relocating its corporate headquarters to Tysons Corner, where it will consolidate multiple offices.

The company has four offices in Northern Virginia, including two in Alexandria. About 180 employees from the facilities are set to move into the new headquarters at 1700 Old Meadow Road, near the intersection of Route 123 and the Capital Beltway.

The move comes after months of weighing a new headquarters location, said Steven F. Gaffney, DynCorp’s chief executive. He said the budget pressures created by sequestration and temporary budgets pushed the contractor to consider a whole range of options, from Texas to North Carolina to Huntsville, Ala.

Indeed, about 80 percent of the company’s back-office functions — and more than 1,000 employees — are already in Texas, said Gaffney.

Still, he said DynCorp saw an advantage to staying in the D.C. area.

“All our peers are” here, he said. “Being part of the herd, being part of the Northern Virginia/D.C. area is important to us, and we’re closer to our customers.”

Still, he said about three dozen jobs now in Northern Virginia will likely move to Texas to consolidate some of the company’s back-office functions.

He said DynCorp plans to move into the entire Tysons Corner building and renovate it, including adding external company signage. The contractor expects to open the new headquarters by Jan. 1.

DynCorp went private more than three years ago when it was purchased by Cerberus Capital Management. Gaffney became chief executive soon after.

In recent months, the company has restructured to focus more of its effort on winning work with foreign companies. The contractor moved from five business units to three: Dyn­Aviation, which will focus in areas such as aircraft maintenance and modifications; DynLogistics, which will encompass work such as training and security; and DynGlobal, a new unit meant to move the company into more international work.
