Construction Contract 1 involves:
Decommissioning and later restoring the former Central Post Office station building
Constructing a ‘temporary station facility’ to the rear of the CPO, constructing two rail tunnels under the CPO and through Lower Queen Street to the eastern ‘stub’ of the Commercial Bay site and from the western ‘stub’ of the Commercial Bay site to Customs Street. Construction Contract 1 commenced during July 2016 with construction of the temporary station concourse and accommodation facility.
As part of CRL Construction Contract 1, the Britomart Transport Centre, situated within the former Central Post Office, was decommissioned to enable CRL tunnel portals to be constructed below.
The current 'dead end' at Britomart will be superseded by east and west bound tunnels, completing the current rail network.
The CPO Building was designed by Claude Paton and government architect John Campbell and originally opened in 1912.
As part of CRL works the CPO will be fully restored and reinstated to its former glory.
Construction Contract 2 included pipe jacking a new stormwater main along the eastern side of Albert Street, between Swanson and Wellesley Streets and strengthening of the Orakei Sewer Main across Albert Street.
To enable the pipe jack and cut and cover tunnel works, the diversion or relocation of many essential utility services along Albert, Victoria, Swanson and Wellesley Streets was required.
This includes stormwater pipes, electricity supply cables, telecommunications cables, gas pipes, sewer pipes and any other service conduit that needs to be safely relocated. Utility diversion is a significant body of work which commenced during December 2015. Pipe jacking and cut & cover tunnel construction began during Quarter 4, 2016.
The main body of work under Construction Contract 2 is the construction of twin cut and cover tunnels along Albert Street from Customs Street to Wyndham Street.
The tunnels will be constructed using the bottom-up construction method where a deep trench up to 18 metres deep is excavated and the tunnel constructed through it, then carefully back-filled and the surface reinstated. You can see more about the construction methods used
