Mammoet Demonstrates its ABC’s

Mammoet has successfully delivered on a first-of-its-kind project in Western Canada. The safe lift, transport, and placement of a bridge structure took place at the end of May 2017 in Edmonton for Supreme Group. The structure weighs 385mt and measures 57.25m long and 11.4m wide with a height of 4.3m.

First Accelerated Bridge Construction in Western Canada

The ABC approach, or Accelerated Bridge Construction method, was used. This allowed for the structure to be assembled away from the bridge foundations and in a controlled, but small, construction area. ABC is safer and more efficient than conventional bridge construction: it removes hazards associated with working near traffic and eliminates the need for working at heights. It minimizes congestion and traffic delays that would be associated with traditional construction methods.

 Three cranes navigated the small construction site to lift the bridge structure and set it on 24 lines of Self Propelled Modular Transporter (SPMT) for transport and placement. A short execution window between 10 pm and 9 am was given, during which the road was closed to allow for safe passage of the SPMT. A smooth, swift operation moved the bridge structure into place and set it on its abutments within the allotted time. Subsequently, the road was opened again, ready for morning  traffic.
