Rented rig gives piling firm the edge

A rented Klemm 702-2 drill rig from Skelair International has helped Norfolk-based Piling & Drilling to meet the demands of a recent restricted access piling scheme in Cambridge without the need to invest in the necessary equipment.

The project formed part of groundworks for a new build extension to student accommodation at Emmanuel College’s Janus House. Continuous flight auger (CFA) piling was specified, but access at the site was extremely restricted. While Piling & Drilling has its own fleet of rigs, these could not operate at the maximum available height within the basement of Janus House, so the company turned to Skelair to find a flexible rental solution.

“Piling is an expanding area for us but it doesn’t make commercial sense at this stage to have a wide range of machines in-house,” says Piling & Drilling project manager Karl Connell. “Restricted access was the main challenge at Janus House and Skelair were able to provide a reliable and competitive rig in the Klemm 702-2.

“Our competitors could not achieve the same operating heights as us with the Klemm 702-2 without removing slabs, which would have incurred an additional four weeks preparation time on site and associated costs. This gave us a distinct advantage and helped us win the job.”

With a floor-to-ceiling height of just 2.55m, the Klemm 702-2 was able to keep within this by operating at 2.5m. The rig allowed the contractor to install the 450mm piles without the need for a winch.
