Foundation Engineers Roger Bullivant Limited (RB) were successful in securing an extension to the existing Department of Engineering at Lincoln University. The extension was to include laboratories, workshops, a 500-seat lecture theatre, seminar rooms and office space.
As the site was part of the existing university, the piling system needed to take account of the surrounding environment. Therefore, minimal disturbance and speed of installation were key factors that needed consideration.
After consultation between RB, BAM and the Consulting Engineer the initial proposed foundation solution of continuous flight auger (CFA) piles was changed to driven precast concrete piles offering a quicker, more cost-effective system.
The project involved the installation of 343no 250mm² and 300mm² driven precast concrete piles to cater for loads of up to 400kN and 650kN respectively.
