Case Study

York Development – Installation of Caisson Shafts

V J Donegan & Co Ltd was engaged to undertake the critical installation of three caisson shafts as part of a major development in York. These shafts, measuring between 2.1m and 9m in diameter and reaching depths of up to 11m, form the foundation of the site’s drainage and pumping station infrastructure.

The high-water table in the area posed significant challenges, requiring careful planning and innovative techniques to ensure successful project delivery.
