Impact
Gave the data center team monitored response information and alerts to help guide follow-up during nearby drilling.
Challenge
Drilling for possible subsurface voids outside the data center called for tracking changes in the building’s measured response.
STRAAM approach
STRAAM collected baseline and continuous acceleration readings with five triaxial sensors from November 30 to December 2, 2012, using a 0.24 g alarm threshold.
Result
Small response changes were recorded at the monitored locations. The work provided information about those locations but did not determine whether voids were present elsewhere on the site.
