Our Role
ByrneLooby redesigned the foundations to a combination of bored piles and cfa piles. The slip lined casings were designed out by carefully assessing the loads and movements on the underlying Crossrail tunnels and limiting the additional load on the tunnels to the maximum surcharge allowance. One area immediately above the Crossrail tunnels was designed with low density fill to reduce the applied loads.
Close collaboration with the Crossrail engineers ensured that the resulting design was approved by Crossrail, with significant cost and programme savings compared to the original foundation design.
