Here’s what’s happening with the CRL Downer NZ and Soletanche Bachy JV construction around the former Chief Post Office (Britomart) building
C1 bulk excavation works continue in the trenches within the Chief Post Office (CPO) building and within Lower Queen Street in preparation for upcoming tunnel box construction works.
The northern trench within the CPO building is now excavated down to 6m and the temporary concrete floor has been constructed for the upcoming mid-level propping installation.
The corbels (the mid-level propping sits on these) have been installed along the trench walls and installation of the walers (steel beams) running along the edge of the walls is underway.
Once the excavation of the very eastern end of the northern trench (what was the station toilet block) is complete, the installation of the struts across the trench will commence.
In the southern trench within the CPO building, bulk excavation continues as does the demolition of the remaining columns and of the old pedestrian underpass.

Down below deck in the station B2 platform level we have cut through the existing wall between the station and back of house where enabling works continue.
