Science Applications International Corp. is warning state regulators that it might have to lay off about 83 employees in Bethesda if a federal contract is not renewed, the state said Tuesday.

The McLean, Va.-based government contractor, best known as SAIC, told the state that the contract involves information technology work for the National Institutes of Health. The layoffs would occur Oct. 28, according to the notice sent to the Maryland Department of Labor, Licensing and Regulation.

SAIC confirmed the information Tuesday but declined to comment further.
