This project was very challenging as the old infastructure had to stay in operation whilst installation was carried out as a majority of this was buried.

As the ground was contaminated screwpiling was the only option as no spoil is produced during installation.

As screwpiling is carried out using excavators it makes this a lower risk to overturning which was also favoured on this project.

This method also allows good and fast manoeuvrability around site as some locations were 100 meters from each other causing no damage due to rubber tracks.
