Infrastructure worldwide can face a range of hazardous events, from earthquakes and hurricanes to fires and terrorist attacks—all of which can result in severe damage, or even structural collapse.
Severe structural damage and structural collapse present a high health and safety risk to the community around an affected infrastructure. Long-term closures resulting from severe damage can also present a high financial risk.
Monitoring, maintenance and repair
Our engineers can repair or strengthen structures to protect against hazardous events. And provide structural health monitoring to evaluate a structure's safety in the aftermath of an event—delivering the data needed to support rapid decision-making and structural repair.
Minimizing hazardous events
In cable-supported bridges, where the main structural elements—the stay cables—are highly exposed and vulnerable during hazardous events, our engineers can retrofit a range of measures to minimize the risk of hazards and special exposure:
DYNA Link anchor box installation at seismic zones to avoid cable slippage during earthquakes
Cable damping device application to prevent excessive and dangerous cable vibrations
Active and passive de-icing system installation to minimize the risk of falling ice and mitigate against iced cable galloping
Implementation of fire protection, anti-vandalism and anti-terrorist measures to protect cables from miscellaneous threats
Supporting new and existing assets
To minimize the risk—and protect new structures against hazardous events, our engineers can consult at the early design stage and tender phases to deliver, install and maintain safe, strong, and smart geotechnical and post-tensioning systems.
We can also retrofit systems to protect existing assets from hazardous events.
