Jackson Civil Engineering picked up two of the Environment Agency’s prestigious Project Excellence Awards at a ceremony held last month.
The first was for the Lower Tame Flood Risk Management Scheme which won the Innovation category. On this project, almost 7km of new flood defences were built to help reduce flood risk to 2,095 homes and businesses in the Lower Tame area.
Innovations on the project included the use of hollow recycled plastic copings, Bentonite slurry cut-off walls, innovative non-return valves and alternative blind-spot systems on construction plant. The judges however, were most impressed by the collaborative working practices amongst the project team which led to these innovative solutions being implemented. The team used a wide range of innovations on the project, going beyond best practice and first time uses.
The second win was for the Kennett Tunnel Inspection project which won the ‘Managing Health, Safety and Environmental Risk’ category. The Kennett Tunnel forms part of the Ely Ouse to Essex Transfer Scheme. This scheme transfers river water from the Norfolk Fens that would otherwise discharge to sea, to the Essex reservoirs supplying water to Chelmsford and Colchester.
The 20km concrete tunnel, built in 1972, has very restricted access which requires a full drain of the entire system before inspections can be carried out. Not only is this practice very disruptive, there is also a significant safety risk associated with putting people down into the underground tunnel.
Instead, the project team used a remotely operated vehicle (ROV) which was able to safely inspect the tunnel and access shafts without the need to send people in. This method was also trialled in 1998, but unfortunately was deemed unviable due to poor visibility. With improved technology, this time round the ROV inspection produced clear results. The project team successfully demonstrated that future inspections of the tunnel can be done with an ROV, eliminating the health and safety risk of this task, and also avoiding the need for a costly drain down of the 20km system.
In addition to these two wins, Jackson had a number of its projects nominated as finalists in the various categories.
Jeremy Walker, Environment Agency Board Member said: “Once again the high standard of entries made the judging task very challenging. The wide range and sheer quality of projects has been very impressive. The increasing evidence of solid and effective partnership working provides great confidence for how we need to operate in the future. Congratulations to all the teams.”
