construction problems with the silver spring transit center became public in march 2013. 
Concrete issues at the Silver Spring Transit Center - The Washington Post

I began this blog in october 2013. in a post dated august 2014 I said:
"Much of the media's (print, TV, radio, internet) coverage of this story has revolved around politics--Republicans blame Democrats, etc. However, the SSTC isn't a story about politics. 

• The SSTC is a story about serious failures in design and construction of a public work. 
• The SSTC is a story about how government has wasted taxpayer money. (53% of the funding for the SSTC are federal funds, meaning ALL taxpayers, from coast to coast, are paying for this seriously flawed lemon. 11% are MD funds and the remaining 36% are Montgomery County funds.)
• The SSTC is a story about public safety for those who will use it--if it ever opens.
• The SSTC is a story about government accountability in protecting the public's investment and their safety.
• The SSTC is a story about how government deviated from the tried and true, competitive methods for selecting a contractor (bids) and for selecting a design engineer and a concrete inspector and tester (multiple firms competing for the project).

The REAL story of the SSTC has yet to be told in the hundreds of media reports over the past year and a half. The real story of how and why Montgomery County selected the SSTC's contractor/builder, the design engineer and the concrete inspector/tester and special quality inspector has not been made pubic."
