From the Washington Business Journal, (11/15/11):
Nonprofit information technology contractor Mitre Corp. is apparently moving ahead with a plan first reported here in June to demolish a building adjacent to its headquarters in Tysons Corner and build anew.
Though a spokeswoman said that the company is not yet ready to discuss the project's timeline, a source with knowledge of the project confirmed that Mitre is moving ahead cautiously with the expansion of its headquarters in Tysons. It's being handled by real estate services company Jones Lang LaSalle, the source said.
