Remember this building where you used to dash in to catch the train?
It's now buzzing, not with train passengers, but contractors preparing to build the City Rail Link tunnels.
Contractors Downer NZ and Soletanche Bachy (DSBJV) are doing the work inside the Britomart Transport Centre building (the former Chief Post Office) in Lower Queen Street in preparation for the cut and cover works to build the CRL twin tunnels from the outer platforms at Britomart.
It's a heritage building (read the history here) so crews are being meticulous to ensure heritage values are preserved and are working with heritage advisors.
Since the temporary station entrance opened at the back of the building, the original Queen Street entrance and building has been off limits.
Here's a sneak look of what is happening inside at the moment.
This includes deconstruction and demolition work and removal of the floor.
You can also see time-lapse videos of the construction inside the CPO
This video explains the work being done:
Outside in Lower Queen Street, those big 10m high red silos dominate the landscape.
Read here what part these silos are playing in the tunnel excavation.
