Mt Eden Main Works Description 2.1 Overview of Works
The main works involve construction along several active work fronts concurrently within the Mt Eden area at any one time, to enable the redevelopment of Mt Eden Station and establish the CRL tie-ins to the NAL. Works will be carried out in a staged fashion. The construction staging and methodologies are described in greater detail in the CEMP. Within the main works area, there are already other works occurring in accordance with the Mt Eden Enabling Works (OPW60350039) and Normanby Road Early Works (OPW60351423) outline plan packages. This ITA EMP has been prepared to address the entire main works area including works in the CRL and KiwiRail designations as outlined in Figure 2.1.

Ground improvements, in the form of deep soil mixing (contiguous piling and grout injection), within the NAL corridor between Mt Eden Road Bridge and Normanby Road; Bulk excavations and construction of retaining walls along the NAL to provide for the rail trenches and installation of new tracks. The excavation will encounter basalt, which will be removed via rock-breaking and blasting. In places, softer ground conditions are anticipated to be encountered, which may require the use of sheet piles; | Mt Eden Main Works
