KGAL to help protect London from flooding for the next decade

Thames BarrierIn November 2012, after extensive research and public consultation, The Environment Agency published recommendations for managing flood risk through London and the Thames estuary (TEAM 2100: Thames Estuary Asset Management). The visionary 80+ year plan was broken down into phases. The first phase (TEP1 ­ covering the next 7-10 years) was put to tender earlier this year.

Against strong competition from four other contenders, the work has now been awarded to a delivery partner led by CH2M and comprising KGAL, Balfour Beatty, Qualter Hall, Critigen and Hunton Engineering.

We specialise in the structural, mechanical, electrical and hydraulic engineering design for water control and already have considerable local knowledge and engineering experience of the River Thames eastern barriers at Barking, Dartford, Tilbury and the Canvey Island defences (as well as tidal surge barriers elsewhere).

The scheme sees the provision and delivery of a programme of capital investment and improvement works for flood defence assets (both fixed and active) across the Thames estuary. We'll be focusing on the active assets: flood barriers and other structures with moveable gates, outfalls and pumping stations.

Working with the Environment Agency as part of the integrated delivery team, we anticipate our role extending to the management and design of those active assets in terms of replacement and / or refurbishment.

Speaking after the consortium’s kick off meeting in London, KGAL director Dave Griffiths said “We’re hugely impressed by the track record and expertise of consortium colleagues; we know many of their engineers personally and of the projects they’ve undertaken individually or with us as collaborators. I’m sure our own previous work for EA, and the synergy within this new delivery team, will have had a part to play when the Agency evaluated the competing proposals”. 

The Thames estuary tidal floodplain forms a corridor which passes through London, North Kent and South Essex. The at-risk region hosts I.25m residents plus commuters, tourists and visitors, plus physical assets comprising institutional, commercial, cultural, civic and heritage sites. The river estuary, grazing marshes, saltmarshes, mudflats and meadows also support a range of wildlife including year round residents as well as winter visitors.

Bryan Harvey, CH2M's global operations director, gives more detail about the TEAM2100 project in this interview with WET News (Feb 2016).
