Construction Schedule and Impact

How will vibrations from tunnel construction be managed?

Covers the vibration impact of tunnel construction, whether the tunnel boring machine (TBM) could damage nearby buildings, and whether vibrations will affect your foundation.

In general, the depth of the tunnel and construction method in rock mean that vibration would not be noticeable at the surface. For construction of the shafts, ALCOSAN and its designers will include specific requirements in the contract documents to prevent vibratory impacts to existing structures as well as monitor ground movement and vibration.
