Undeslung MSS Heubach

HOW TO DEMOLISH OLD AND BUILD NEW BRIDGE USING THE SAME EQUIPMENT?
🏗 ♻ Replacement of Heubach viaduct using the same Movable Scaffolding System for Span by Span demolition and new construction.
#Engineering #Sustainability #productivity
✅ The Heubach valley bridge consists of two parallel structures, which were demolished and rebuilt in two construction phases.
Demolition of the old bridge and the construction of the new Heubach bridge was awarded by Die Autobahn to the contractor Implenia .

Due to constant succession Strukturas team accumulated more than 50 years of bridge building equipment engineering legacy.
On behalf of it our engineers developed bridge deck demolition or replacement method using Movable Scaffolding System - MSS.
It's cost saving, productive and sustainable methodology developed by Strukturas:
- Minimal intervention to existing infrastructure.
- Using MSS for demolition allows the bridge crossing traffic to remain open throughout all of the demolishing and new construction period.
- The MSS could be assembled on the ground and later could be lifted with 4 strand jacks.
- After finished demolition MSS could be lowered with 4 strand jacks on the ground for safe and productive MSS dismantling.
- The challenging MSS installation conditions can be carried out by professional site crew from Strukturas.
- After the demolition this same MSS could also be used for the construction of the bridge deck. This approach saves time and resources, making the construction process more efficient.
The engineering challenge is to avoid an overloading of the superstructure during the demolition and to ensure a safe load transfer within the load capacity of the MSS.
