TEAM2100 investigates structural condition of Thames flood defences
Detailed engineering and structural investigations into the condition of tidal flood defences in London and the Thames estuary are currently being carried out by TEAM2100, which includes engineering and programme management firm CH2MHill, construction partner Balfour Beatty and other specialist contractors.
The work is being carried out as part of the Environment Agency’s (EA) ten-year programme to refurbish and replace tidal flood defences in London and the Thames estuary. The EA said it inspects all defences in London and the Thames estuary at least annually and in most cases twice a year. However, to make the most efficient use of the ten-year work programme, more detailed investigations into the condition of some of these defences were needed.
This work, which began in March, will be largely complete by March 2016. The defences include the Thames Barrier and 350km of flood walls and embankments, smaller barriers, pumping stations and flood gates. This system of defences protects 1.25 million people and £200bn worth of property.
The EA said many of the defences are more than 30 years old, and in some cases 100-plus years old. The investigations will provide information about the condition of individual defences as well as about the system as a whole.
TEAM2100 is carrying out the first part of the EA's Thames Estuary 2100 Plan, which sets out how to manage tidal flood risk in the Thames estuary throughout the 21st century. It will improve tidal flood defences in London, Kent and Essex from 2015 to 2025.
