Extension of the BedrettoLab has started

The BedrettoLab entered a new phase in November 2021 (see news article), in which the Lab is being extended to include a second testbed. The first step of the retrofitting has been completed, including the installation of electricity and lighting to 2900 TM (TM = tunnel meter).

In the following weeks, the ventilation ducts will be extended to 2900 TM and we will begin the first phase of cementing the tunnel passage. Then a series of boreholes will be drilled, one set for long term seismic monitoring and another for geologic exploration of the second testbed. These will be completed late Summer 2022. Afterwards, a second phase of construction will finalize the road extension to 3050 TM and complete additional safety reinforcements in the latter part of the tunnel.
