In order to protect the proposed Preston Waste Transfer Station from a 1 in 200 year flood from the adjacent River Ribble the level of the site had to be raised by up to 3m. The increased loading from the 3m high platform was predicted to result in unacceptably large post construction settlements which would result in a serviceability failure.

Geotechnical design and risk management measures were provided by PaSCoE in the form of pre-fabricated geosynthetic vertical drains and soil surcharging to force the anticipated settlement to take place within a short time period

Continuous monitoring using settlement plates across the site was implemented to manage the consolidation process with all settlement being built out during the construction phase.
