        (rig weight <2 tonne) should be considered. Rigs such as the M-Track or Belpile’s CFP
        rig would be suitable and provide more manoeuvrability.
        This will also allow all equipment movement to remain within the disturbance footprint.
    8. Provide tie between contiguous piles to maintain stability and allow excavation of lower
        platform.
        Local excavation using 5 tonne excavator.
        Stability analyses to assess requirements.
    9. Excavate lower platform with recommendations as for Step 6.
    10. Piling to retaining wall and structures on lower platform.
        Use of small rig (<2 tonne) is recommended. Rig to sit totally in cut.
        Where the finished floor level is above natural ground level, i.e., suspended floor, local
        preparation of a platform is recommended to suit small rig size. To minimise
        disturbance, cantilever construction is recommended for the structures in this area.
        Piling rig to be craned out on completion.

Reference to Figure 4 produced by Dr Philip Shaw highlights the locations of cut, fill and
retaining structures.

At each stage/step of development, it is recommended that the experienced on-site
geotechnical engineer provides certification of the stability.


We trust this meets the requirements of the mediation agreement. If there are any questions
on the above, please contact Jim Dixon of this office.
