What is piling?

Andrew, Site Engineer. Hi, I’m Andrew. I’m working on the Reservoir Level Crossing Removal Project. Piling is when we dig vertically into the ground. We drop in a steel cage reinforcement and concrete into the hole, and that forms the foundations of our super structure. So the piling rig has an auger head. Depending on the soil conditions that we experience they’ll change the auger head, and that just attaches to the rig and drills down. So at Reservoir, we’re doing the traditional grouped piles, but we’re also doing monopoles which are these giant 2.1 metre diameter single piles, and these single piles sit underneath each bridge pier. The benefits of monopiling versus a group of piles is that we save space, it saves time, and particularly where we’re working in this live rail live traffic environment we need as much space as possible. We’d like to thank everyone for their patience and we’re all looking forward to see the bridge come together in a couple of months.
