 Piletech worked closely with Transfield Worley's design team from an early stage, enabling us to optimise a piling package that integrated well with the overall design. Piletech screw piles were chosen as a proven solution that had worked well on the site in the past, allowing fast installation with minimal vibration, allowing the plant's operations to continue unaffected.

 Over 400 piles were installed within an 80m x 30m construction platform - on programme and on budget, giving Transfield Worley the successful start to their construction programme that they needed. This was delivered in the lead-up to the Christmas period in an operational facility which demanded close attention to health and safety protocols, high levels of compliance, and close liaison with the client to ensure the project was delivered smoothly.

Transfield's Project Manager for the Mangahewa Development, Mark Hatch, commented on Piletech's performance, noting "They did an outstanding job for us on site installing over 400 piles and pile collars in 6 weeks. HSE performance was good and we were impressed with the commitment of the Piletech project management, engineering and site teams to delivering the piling ahead of programme. It has put the project in a good position for the next phase."
