DESIGN & TECHNICAL

---

 In-house engineering design is primarily provided by Australian Structural Engineers supported by other internal and external engineering professionals. ASE works closely with client’s engineers and staff to determine the most cost effective design to meet the client’s needs. He is able to design the foundations from first principles up or take existing designs and convert them to cost effective cast multi turn Screw Pile alternative designs. An agreed appropriate charge is only made if the client proceeds and uses the Pile East design with full certification on completion of the project. 

 The first release of a Multi Turn Screw Pile Helix some twelve years ago started the thinkers in the Piling Industry to explore and refine the Multi Turn Helix into what it is today.
After much discussion and analysis of how a Multi Turn reacts in various soil types and clear evidence of enhanced performance over traditional Single Turn Plate Helix in dense / very dense sands and clays, the theory has evolved as to “why it is so”. 

Pile East offers a broad range of testing for All Screw Piling Systems and has all the necessary equipment to conduct any of the tests chosen by the client. Tests include;

• Static Load Test – for the compression, tension (uplift) and lateral load testing of installed screw piles, in accordance with pile testing outlined in AUST/NZ Piling Standard AS/NZ 2159 using a series of large beams, hydraulic jacks and hold down piles.
• CAP WAP – Computer based compression test. Carried out by a 3rd party testing company who specialises in this form of pile testing. Pile East provides the necessary test piles, hold down piles and drop weight rig onsite to complete this test. This test allows for multiple pile testing within the same day.
• Integrity Testing – An alternate computer based test determining the integrity of the pile, using measurement or sound resonance to determine the load being applied to the steel shaft of this pile. Again carried out by a 3rd party testing company who specialises in this form of pile testing. Pile East provides the necessary test piles, with the testing company providing all other equipment. This test allows for multiple pile testing within the same day.
• Portable Tension / Lateral Load Test – The company uses a portable test rig which is capable of tension and lateral load tests up to 200 Kn (20 Tonne), the rig is certified and relates hydraulic pressure from the rig to Kn of load bearing applied. Engineers are free to design their own test regime using this equipment whereby loads are held and pile movement measured over any given time. This allows many piles to be tested within the same day and gives the engineer sound across-the-site data. Larger rigs may be developed to test higher loads than 200 Kn subject to negotiation with the manufacturer.

Analysis of results and advice on the various testing methods is available from Pile East engineering personnel.
