Seattle Tunnel Partners
Seattle Tunnel Partners finished disassembling Bertha and have concluded the damage the machine sustained is more extensive than previously thought.
The latest inspection of the Alaskan Way Viaduct found additional ground settlement, wider cracks and two new cracks on columns near the area where the Seattle Tunnel Partners are working to fix Bertha, the giant tunnel boring machine that is supposed to dig the highway tunnel to replace the viaduct along Seattle’s waterfront.
Workers at the Seattle tunnel project have started pulling pieces of the broken tunnel machine called Bertha to the surface for repairs.
Bertha is on the move.
The manager for the troubled Alaskan Way Viaduct replacement project told lawmakers Thursday that the state and the contractor are still battling over tens of millions of dollars in repairs dating back to 2012, but even if the contractor declares bankruptcy tomorrow, the project could still be completed.
A new highway tunnel through downtown Seattle won’t be open until August 2017, about 20 months behind schedule, state transportation officials said Monday.
State transportation officials gave Seattle Tunnel Partners the OK on Tuesday to resume excavation on a pit being dug to reach and repair Bertha, the broken tunneling machine.
An effort to repair the giant tunneling machine stuck under downtown Seattle is going more slowly than expected.
The new tunnel would allow workers to dig up and repair the now-stuck boring machine
It seems that everything connected with the effort to dig a highway tunnel under downtown Seattle is big — from the tunneling machine that stopped working last December, to a large plywood wall planned to shield neighbors from the noise of repairing the machine.
