Take their word for it?

David Dise, Director, Department of General Services at Montgomery County, MD, says “It (the Silver Spring Transit Center) will absolutely be safe”. ( http://wamu.org/news/13/11/20/repairs_on_long_delayed_silver_spring_transit_center_could_be_done_next_year )

So do private consultants hired by Montgomery County and WMATA.

Of course they do.

Do you accept the opinions of those who have a "history" on the project and are paid by Montgomery County, WMATA or anyone else who has a “history” on the project?

I don’t. Give me an independent opinion from an expert(s) who doesn't have a "history" with the project and who is not paid by Montgomery County, WMATA or any of the other "players" in the project so far.
