CH2M Hill chosen for £300m Thames Estuary Asset Management Programme

The Environment Agency has chosen CH2M Hill ahead of Jacobs to maintain and improve flood defences along the River Thames under the £300m Thames Estuary Asset Management Programme.

Balfour Beatty is CH2M Hill’s delivery partner for the contract, along with specialist suppliers Critigen, Hunton Engineering Ltd, KGAL and Qualter Hall.

The contract is for the first 10 years of a 100 year programme developed by the Environment Agency to protect London and the Thames estuary from tidal flooding up to 2100.

CH2M HIll will plan and deliver investigation, design, capital maintenance, refurbishment and replacement works on existing tidal flood defence assets along the 170km length of the Thames estuary.

The contract represents one of the world’s largest flood risk management programmes.

The Thames estuary tidal flood defence system extends from Teddington in West London through to Sheerness and Shoeburyness in Kent and Essex, protecting 1.25m people and £200bn worth of property and is formed from over 3,500 different assets, including the iconic Thames Barrier.

The suppliers will form an integrated delivery team with the Environment Agency to carry out the work.

The race for the deal was whittled down to two in September after Costain, Mace and Morgan Sindall teams were among the contractors to lose out.

CH2M HILL’s managing director for Europe, Mark Thurston, said: “This project is a vital piece of infrastructure that fits closely with our other major programmes in London, including Thames Tideway Tunnel, Crossrail and High Speed 2.

“Not only will this programme help maintain London as a globally competitive city, it also provides a significant boost to the British engineering sector and the creation of long-term employment in the UK jobs market, with the project requiring skilled engineers throughout the planning, investigation, maintenance and refurbishment works of the next 10 years.”

The deal is a filip for CH2M Hill which announced in September it would shed 5 per cent of its global workforce.

Programme capital works:

Major refurbishment works of fixed assets, such as tidal walls and embankments;

Refurbishing works of active assets (including major flood barriers)

New assets such as pumping stations;

Capital renewals and replacements;

Packages of major or complex maintenance works, such as repairing long lengths or fixed flood defence walls or subsidence of earth embankments.
