The buildings of the Wald-|
egg Provincial Vocational School (Lower Austria) are currently under a thorough
Parts of the new building complexes have to be cut into the slope, which re-
quires slope protection measures
These measures are carried out in form of bored pile walls with anchoring at one or two levels. The pile
diameter is 90 cm and the pile lengths up to 18 m.
BGG Consult was commissio-
ned by the contractor with consulting regarding the opti-
mization of the foundation
system on the one hand, and with the detailed design of the slope protection measu-
res on the other hand.
The latter included earth statical analyses as well as the dimensioning and the design of the bored pile walls.
and Building Pit Protection for Construction Phases 1 and 2:
In close cooperation with the technicians of the contractor, a concept with non-reinforced bored piles was
developed for the foundation of the structure, which replaced the originally planned underpinning by means
of jet grouting.
For the protection towards the existing building, jet grouting was also omitted and a tangent pile wall
established. Thus, all special heavy construction could be carried out with one system.
By this value engineering, a technical optimization was done with namable cost benefits for the client as
well as for the contractor.
