RESCU PROGRAM: Gravity Pipeline Project

TBM Status Update – June 14, 2021

As of June 14, 2021, Salus tunneled 12,208 feet from its launch shaft and built  2,437 rings. Tunnel production towards the Front of Plant (FoP) project site continues, as the date for TBM break-in to the receiving shaft approaches. The Surge/Flow-Splitter shaft (SFS) element of the FoP project is serving as the TBM retrieval shaft before being repurposed to be part of the FoP project.

BBJV will perform demolition of a portion of the SFS Shaft wall, limited to the specific section where Salus will be breaking through. This demolition will reduce the extent of the concrete wall that the TBM will need to mine through to break in. The demolition work follows a planned approach to ensure safety of the break-in operation. 

Once partial wall demolition work is complete, BBJV will fill the SFS shaft with soil and water to allow Salus to mine into the SFS under safe conditions, like the mining conditions Salus has encountered over the 3.5 miles of mining completed so far.  

As Salus enters the final stretch of mining, BBJV is keeping up with its daily tunnel task force and check in meetings where the real-time TBM and mining parameters are discussed in detail.
