(TPSS) and Tie Breaker Station (TBS) buildings and are
continuing to connect these facilities with communication and
power cables to the guideway and stations.
• East Stations – Continue roofing, escalator installation, and
electrical and plumbing and set rail ties and track through the
stations. Reston Station platform paver installation is ongoing and
Loudoun Gateway and Ashburn Stations vault structural steel
welding and painting continues.

Alkali Silica Reaction (ASR) Issue
• Universal Concrete Products (UCP) fabricated the At
Grade Station Precast Concrete Elements:
On May 16 the US Department of Justice unsealed a Qui
Tam complaint against UCP. The complaint contains a
previously unknown allegation that UCP used a concrete
aggregate that does not meet the specified alkali-silica
reaction requirements. This reaction can be deleterious to
the service life of concrete structures.
CRC has been notified that it must address this issue.
The Project is working with its engineering consultants to
investigate and determine if this is an actual concern.
