Over a four year construction period we are providing significant works under a variety of challenging conditions:
- Variable ground conditions - ranging from soft peat to volcanic tuff and basalt.
- Dealing with high water table and considerable ground water flow.
- Installing large diameter pipes in urban streets with large traffic volumes.
- Locating, supporting and/or diverting underground and overhead services.
- Managing the large volume of materials (spoil and aggregate) carted in and out of the congested site.
