Coogee Chemicals Pipe Bridge

Project Owner – Coogee  Chemicals
Client – WBHO Civil
Date – Sept 2013

Working closely with engineers Pritchard Francis screwpiles were able to be incorporated into a foundation design for pipe bridge over a railway line for Coogee Chemicals at their loading facility south of Fremantle. Due to the very large design impact loads that the foundation had to withstand and the restricted area available, raked screwpiles were a good solution saving large volumes of concrete and reinforcement what would normally had been required.

Pilewest engaged Probedrill to undertake a CPT probe to a depth of 12m in each foundation base allowing a very accurate existing soil profile to be used in the screwpile design. This ensured that the screwpiles were founded at the correct level and the required installation torques were achieved.

Working within a very small corridor Pilewest was able to install 12 raked screwpiles in each foundation quickly and efficiently without disrupting scheduled rail services and operations.

Mondarra Gas Storage Facility

Location- Dongara, Western Australia
Client – Enerflex Process Pty Ltd
Date – February 2012

Working closely with Enerflex Pilewest was able to install over 550 piles in 4 days allowing a 140 man camp to be commissioned and operational within 3 months. Screwpiles were the preferred foundation solution to allow the project to be installed to such a tight timeframe with the additional benefit that they can be easily removed at the end of the project life.

Macedon Construction Camp

Location  – Onslow, Western Australia
Project Owner – BHP Billiton
ECPM – Technip
Client – OTOC Australia
Date – August 2011

Pilewest designed, supplied, installed and tested screwpiles foundations for the new 350-man new construction camp for the Macedon Gas Project, including, kitchen refuge and associated service buildings.

Pilewest undertook additional geotechnical investigation across the site to determine the existing ground conditions to enable an optimum screwpile design. Design of a new bolted adjustable top fixing bracket enabled fast and easy installation.
