Lord Hills Bridge

The contract was part of the Crossrail Project and involved the stabilization of the ground underneath the Lord Hills Bridge.

This involved the replacement of the existing ground with a weak concrete mix, to a depth of 13.0m on one side of the bridge, with a compression slab anchored by two contiguous piled walls at the other. The majority of the work was required directly underneath the existing bridge, which had an available headroom of just 5.1m.

The piles constructed were 1200mm diameter to 13m, 1050mm diameter to 17m, and 900mm and 600mm diameter up to 13.0m.

The contract was best suited to the Martello MP5000 series rig, but as this had a headroom limitation of 6.0m, Martello proposed a redesign of the existing rig and equipment to enable it to work in 5.0m of headroom, but nevertheless to drill 1200mm diameter piles to 13.0m. From initial placement of the order, Martello carried out the design, fabrication and modification work in less than 6 weeks.

The Lord Hills Bridge project involved;

• 134 no. 1200mm ground stabilization piles to 13.0m
• 56 no. 1050mm diameter contiguous wall piles (fully reinforced to a depth of 17.0m)
• 101 no. 900mm diameter secant piles for ground stabilization
• 220 no. 600mm diameter secant piles for ground stabilization
• The contract was undertaken with a very tight programme period of 10 weeks and was delivered ahead of programme
