Kingerlee are currently progressing with the construction of a new quadrangle for Pembroke College, Oxford. The project consists of five new buildings and the refurbishment of a Grade ll listed existing building which provide 102 new bedrooms, lecture theatre, kitchen, cafe and seminar rooms linked to the existing Chapel Quadrangle. The new development is linked across Brewer Street via a bridge.
During the sub structure works significant archaeological excavations are being undertaken, the site has uncovered medieval tenement settlements along with a tannery and brewery dating back to the 13th century.

Alongside the archaeology we are currently boring approximately 100no secant piles to form retaining walls for the basement construction along with 400no bearing piles for the structure. The piling rig is a Soilmec SF-50, weighing 40 T when fully operational; the continuous flight auger system is a centrally fed through the auger to place the concrete under high pressure. Its motor is capable of driving a 900mm auger to a depth of 25m.
Works on site are due for completion for the new academic year 2012/13.
