Silver Spring Transit Center
Structural Evaluation of Superstructure
March 15, 2013

The SSTC is a cast‐in‐place (CIP), post‐tensioned reinforced concrete structure with two elevated structural levels and an at‐grade level. The facility is located at 8400 Colesville Road, Silver Spring, Maryland.

During construction, circa 2010, concerns were raised about the thickness of the elevated slabs and positioning of the post‐tensioning tendons.

In 2012, Montgomery County retained KCE, who in turn retained Wiss, Janney, Elstner Associates, Inc. (WJE), Walter P Moore and Associates, Inc. (WPM) and others to assess, as a team, the as‐designed and as‐built structure. The purpose of this report is to summarize KCE's evaluations.
