Fairfax County delivered inaccurate information in a resolution passed Monday urging the commonwealth to consider putting multibillion-dollar rail project out to bid, according to a group of contractors vying to build the track.

A motion before the county’s Board of Supervisors alleged Dulles Transit Partners slashed design features and provided suspect cost estimates — driven by “excessively high rates of profit” — for the Dulles Corridor Metrorail project. A scaled-back version of the resolution passed that night, asking the state “to seriously weigh the option” of seeking other proposals.
