Rock Foundations (Gibraltar) were engaged to provide a ground engineering solution for a complex arrangement of new foundations for the proposed extension to the Gibraltar Law Courts as well as providing a means by which the existing structure could be underpinned.
All of the works had to carried out in manner which would be sympathetic to the existing historic building and cause minimal disruption to the ongoing, day-to-day activities of the institution. Access to the site was extremely difficult which meant that any proposals could only include the use of restricted access plant and machinery.
One of the many challenging issues faced during this project was a high water table which influenced the design for the piling works. A number of techniques were employed to deal with the logistical and geotechnical difficulties during the piling phase, the primary pile being a 300mm SFA pile. Despite the restrictions and the complications the works were completed within budget and within the programme timeframe.
In order to complete the works to the required standards Rock Foundations's specialist teams employed a Klemm 701 for piling with a Kitten Rig for the underpinning.
