Tennenbacherstraße Road bridge Freiburg im Breisgau

Cleanly wrapped

KREBS + KIEFER, on behalf of the Office for Parks, Gardens and Civil Engineering, carried out a building works inspection on the road bridge. As the next stage, the experts used a variant study to determine the most promising and most economical approach: a partial renewal of the superstructure and renovation of the existing retaining walls with sprayed concrete. The demolition scaffold was designed so as to protect the supply lines running along under the bridge. A protective sheet was used to shield the bridge surroundings against the dust and dirt, which inevitably occurred during the renovation of the abutment and retaining walls.</lp>

With strict planning and local construction supervision, KREBS + KIEFER managed to complete the work in the six weeks specified for the annual draining and cleaning of the commercial canal.
