Is concrete being poured at the SSTC? Who knows? It’s been
over a month since the media reported what’s going on at the SSTC.
It’s cold; temperatures are in the 30s. We know from the KCE
and WDP reports that the SSTC’s concrete strength and cracking problems are due
in part to improper handling (adding water) and curing (lack of heat) in cold
temperatures. We also know that concrete inspection and testing were not performed
in accordance with the SSTC's construction documents and standard industry
practice. (KCE’s report “Silver Spring Transit Center Structural Evaluation of
Superstructure with Exhibits” and WDP’s report “WMATA Report - EVALUATION OF
SILVER SPRING TRANSIT CENTER” can be viewed and downloaded at http://www6.montgomerycountymd.gov/mcgtmpl.asp?url=/content/DGS/DBDC/RegionalProjectPages/SilverSpringProjects/sstc.asp
)
The media are our eyes and ears. We won’t know if they’re
pouring concrete at the SSTC if the media doesn’t report it. We won’t know if
it’s the same concrete subcontractor(s), general contractor (Foulger-Pratt) and concrete
inspection and testing firm (Balter) that did the job before.
We won’t know what measures have been taken this time to assure that the
concrete is mixed, transported, handled, placed and cured correctly. We won’t
know if it’s being done right this time.
C’mon, media, report this story!
