Both height and width access issues addressed with appropriate equipment and short pile segments

Residential and Commercial Projects

Both height and width access issues addressed with appropriate equipment  and short pilesegments

Federation Square Lift –

Problems :   Limited Access – Contaminated Soils

Solution – Small machine , 6 metres of segmented screw piles to bedrock . Contaminated material $15K to remove .

Harbourtown Shopping Centre

Escalator and Suspended Walkway Additions

Problem – Very limited access, Shopping Complex open all hours, Contaminated Fill, 30 metre long Piles

Solution – Small Excavator ,Segmented screw piles in 3 metre sections to bedrock.

Adelaide Living Beaches – Pumping Station

Problem- Shallow water table, collapsing sands , corrosion , lateral

Solution – Large diameter heavy gauge  screw piles , founding on dense sands at depth.

Australia Post Sorting Centre - Essendon

Design Problems: up to 6 metres of contaminated fill , including building rubble – 800 piles  in total

Solution – Segmented screw piles installed to bedrock.

Heller St Townhouses

Problem – Contaminated Fill from 80 year old Tip Site , lateral loads imposed on structure

Solution – Large Capacity Segmented raking screw piles in 6 metre sections to bedrock tied to band beams.

Cranbourne Botannical Gardens-

Problem – Significant Lateral Loads ( Wind ) , Shallow water table and collapsing soils

Solution – raking screw piles in 3 metre sections with pile cap

Factory Complex - Wirraway Dve , Port Melbourne

Problem – Collapsing Soils , High Water Table , Narrow and variable band of founding strata for high line loads

Solution – Extensive Static load testing of piles with CPT logs used for design. Closely spaced screw piles in shallow beams with twin helix design.
