Tunnels
Helped avoid major cracking of adjacent structures and kept construction movements within tight tolerances during the Central Artery/Tunnel construction.
Transit
Provided instrumentation and monitoring during demolition to safeguard buildings and utilities surrounding the site.
Wind
Tested over 1,000 samples in-house and completed over 4,000 tests within the client's required schedule.
Bridges
Designed an emergency instrumentation plan and mobilized a monitoring system to ensure timely reopening of the bridge.
