Other Structures

Towers, Wind Turbines & More

CDI has felled hundreds of tall, slender, steel structures, including guyed towers up to 2,000’ tall, free-standing towers up to 600’ tall and wind turbines almost 600′ tall, under a variety of site and structural-condition circumstances on six continents.

CDI’s engineered preparation for and remote explosives felling of such structures are more cost-effective than dismantling as they eliminate schedule and cost uncertainty for crew/crane standby due to elevated winds which often delay dismantling operations. Explosives felling is far safer than mechanical tripping or pulling structures over with cables as the risk to workers using such operations is eliminated.

Whether tall structures are in pristine condition or have been condemned due to weathering, fatigue or damage due to structural failure, impact or thermal events, CDI’s remote felling techniques can dramatically mitigate risk to workers. Our operations require a minimum of structural modification to damaged structures, near grade, in a matter of hours to put them on the ground safely.

Where insurance companies are involved, CDI’s work can be designed to mitigate the loss by protecting foundations for re-use. CDI’s plan can also be designed to preserve artifacts, as necessary, to facilitate post-demolition analysis and investigations into the cause of the original event.
