[7] The new rail trench and associated sunken station were to be constructed with up to 16m deep diaphragm walls using specially imported cranes and specialists.

This was required due to the unstable, water-logged soils and the need to avoid settlement damage to close by buildings.

The procedure to construct the 1 km of trench (with finished depth of up to 8m) involved multiple temporary shifts of the railway line and of various associated roads, and was called the most difficult part of the DART railway development programme in Auckland.

[10] Wet ground conditions had also forced a redesign of the trench methods, and delayed the project start by six months.
