Transportation Sector

CTLGroup-Qatar has extensive experience in the structural evaluation and innovative improvement of bridges, tunnels, underpasses and culverts. Our project expertise worldwide encompasses the entire lifecycle of bridges, from design optimization and construction innovation; to construction planning, material testing and troubleshooting during construction; to structural health monitoring; load testing to extreme in-service event analysis; to extending service life and rehabilitation of aging structures.

The firm also has a long history of bridge engineering improvement. Our signature services include the inspection and evaluation of cable-supported bridges, as well as cable damping and non-contacting cable force measurement. Additionally, we perform suspension bridge and tied-arch hanger force measurement and ultrasonic flaw detection for cable anchorages. One of our most noted projects, the Hale Boggs Memorial (Luling) Bridge, involved a complete stay-cable replacement for the 1,221 foot long bridge.

Our integrated consulting and laboratory testing services, as well as our multi-disciplinary approach to all projects, allow us to provide a vast range of solutions for both new and existing bridges alike. For the evaluation, maintenance and upgrade of existing bridges, we have provided:

Comprehensive nondestructive testing of post-tensioned and reinforced concrete
Field inspection and condition assessment
Failure analysis and investigation
Remote wireless structural health monitoring systems
Corrosion rate monitoring and service life assessment
Post-tensioning tendon inspection and rehabilitation
Service life modeling
Bridge Load Testing (both Static and Dynamic)
