Restricted access piling rig installation automatically promotes the use of screw piles as the most cost effective and time efficient piling solution available

This has again been demonstrated through the successful design and installation of 985kN/460kN (ultimate) compression/tension screwpiles at Wesley College redevelopment works.  In 2016 Screwpile Australia has again been selected to provide a cost effective piling solution.  Installation torques were estimated to be up to 200,000Nm so access for a 35t excavator was needed.  Screwpile Australia is the only screw piling company in Western Australia that has a QA calibrated 200,000Nm pendulum rotary powerhead and Torquatron monitor.

Limited site height & width restrictions made machine access challenging for Screwpile Australia's Operations Manager Andrew Gordon and installation needed to occur next to existing walls for new foundations.  The location was full of existing underground service so care and location accuracy for the screw piles was critical.  The experienced and committed screw piling installation team of Matt and Andy made sure installation was in accordance with Screwpile Australia's ISO-9001 QA project management procedures.

Foundation Engineering’s senior design engineer, Ali Bataghva, provided a design solution that addressed the induced pile moment forces due to existing wall and services locations.  The overall design was cost effective and on budget for the builder.

Back in 2008 Screwpile Australia installed a number of 400kN compression piles in challenging locations at Wesley over existing walls as the image below shows.

Foundation Engineering Group management extends their appreciation to the builder Cooktown and RD Constructions for the close working relationship in ensuring a successful outcome for all parties concerned.  We look forward to the opportunity in working with you in the near future.
