Challenging Piling Projects

This recorded webinar investigates the construction of two challenging piling projects at the Sydney Airport Metro Station and the Bridge over the Macquarie River at Dubbo NSW.
Piling for the Sydney Airport Metro Station
Presenter: Stephen Harkin – Wagstaff Piling.
This case study will present the installation of bored concrete piles in the basement of station boxes for the new airport metro rail line. The presentation will include discussion on installing deep, large-diameter, heavily reinforced bored concrete piles in a 20m deep basement and the challenges of concrete quality & delivery. Pile load and integrity testing results will be discussed along with innovative construction processes introduced to streamline the installation process and ensure the quality of the final product.
Piling for the Bridge over Macquarie River, Dubbo NSW
Presenter: Daniel van Beek – Wagstaff Piling
Concrete filled, driven steel tube piles were selected as the piling for the new Bridge over the Macquarie River at Dubbo NSW. Wagstaff Piling were engaged to install, splice and test drive steel tubes for this major Transport for New South Wales regional project. This case study will present on the construction challenges involved in installing up to 58m long steel tubes both, on land, and in the river. It will discuss splice welding of steel tubes, dynamic pile load testing with different size pile driving hammers, sheet piling and concrete filling.
