Project
Commentary
|
|
|
|
| |
The
combination of the Jet Grouting and JetCurtain Grouting techniques, which
were proposed by Forasol as a variant to the base project (diaphragm wall
casting), proved to be in interesting solution.
|
|
| |
|
|
| |
In
effect, we were able to reduce nuisance to adjacent urban structures by
reducing vibrations and truck traffic. Additionally, our solution enabled
us to work directly adjacent to nearby structures without the risk of structural
damage.
|
|
| |
|
|
|
|
| |
Finally,
our solution resulted in a significant cost reduction for the foundation
solution, and met the construction timelines imposed by the client. |
