Slider Project

London City Airport – (BAM Nuttall)

CA Drillers worked with BAM Nuttall to deliver concrete cutting and sawing services for the airport’s development project. Our job required precise operations in challenging locations, which we achieved on time and with high-quality results, earning us to be shortlisted for an award by The International Association of Concrete Drillers & Sawers.

Due to tight schedule constraints centred around the piling contractor, a daily requirement existed for cutting 80 linear metres (600 mm / 700 mm deep). To meet this demanding timeline, we had to consider installing 40 metres of track at a time with two saws operating concurrently. This was achieved while working from a barge and implementing rigorous water management measures to contain the substantial amounts of water/slurry generated, as, for environmental reasons, it was imperative to prevent contamination of the water within The King George V Dock.

Our cut line was positioned 200mm above the water level, adding significant complexity, particularly since we had to cope with the constant motion of the working barge. Another challenge we faced was that the protective measures used had to be removable daily to accommodate the arrival of the night barge, which was tasked with lifting the cut concrete sections.

Our final solution involved the installation of a 150mm steel guttering system beneath the cut line. This system was installed in 20m sections in both directions, each with a very slight incline, leading into a specially designed container. The resulting waste water/slurry was then pumped into 1000-litre IBC containers located on the barge. These were removed each evening for recycling through a silt buster.
