Five weeks after completing Kirtling Street shaft base slab pour, the Camfaud Special Projects team was back at the bottom of a 50 metre deep shaft, this time at Carnwath Road, repeating the exercise. Our customer at Carnwath Road was BMB jv; BAM Nuttall, Morgan Sindall and Balfour Beatty, and the concrete was supplied by Hanson Concrete.
The Carnwath Road shaft is narrower than that at Kirtling Street and so there was slightly less concrete in the slab. However, in terms of resources needed to carry out the pour safely and successfully, it was very similar.
Camfaud supplied three concrete pumps, one placing boom, high pressure delivery pipeline and ancillary equipment. As with Kirtling Street, we provided two shifts of Thames Tideway inducted, CPCS qualified operators working round the clock over a full weekend to complete the pour.
