Thames Tideway has just published it’s August 2018 video update. It includes, at around the 3 mins 25 second mark, time-lapse footage of the Kirtling Street shaft base slab pour.
The pour, the biggest on the whole Tideway project, was carried out by Camfaud for the Tideway Central contractor Flo jv, a joint venture between Ferrovial and Laing O’Rourke. The concrete was supplied by London Concrete from their nearby Battersea plant.
Camfaud supplied three high pressure concrete pumps, three placing booms, pipeline and ancillary equipment to place approximately 3,350 cubic metres of concrete at the bottom of the 50 metre deep shaft. Two shifts of Camfaud operators worked round the clock for 60 hours to complete this concrete pumping marathon.
This pour follows on from the work that we did a few years ago on the Lee Tunnel project that was highlighted recently in the first episode of the BBC2 tv documentary The Five Billion Pound Super Sewer.
