Tunnel Boring Machine (TBM)

Miss Chelsea
SAK Construction’s TBM, Miss Chelsea is on the move, headed NNE, grinding through 1700+ feet of bedrock, going where no one has gone before.
Interesting boring job.


operator conveyance
Drive to work, ride the man-basket down into the hole, fire up the TBM. How is the machine moved forward? What protective gear does the operator wear? At the moment it’s a horizontal short walk (100+ feet) from the tunnel entrance to Ms. Chelsea. Later on it’ll be longer. Bike to work? What is the lighting like in there? Any chance of a live video feed?

I am on the road to understanding black and white photography.
