Bridgwater Tidal Barrier
KGAL has been retained by AtkinsRéalis (AR) to prepare the detailed mechanical design of the two new
vertical lift wheel gates (i.e. gates ütted with rollers to permit movement under hydrostatic load) that
will form the physical moveable ýood defence elements of the overall Bridgwater Tidal Barrier structure
design being prepared by AR on behalf of the Environment Agency.
Our scope of design work also includes the detailed design of the mechanical and electrical winch hoisting systems for the gates and the preparation of the functional
outline design of the Motor Control Centres (MCCs) for the winches. In addition, we have been asked to prepare the detailed design of the wheeled stoplog systems to
enable the gates to be isolated for both initial installation and future maintenance activities. Further to this, we have also designed a dedicated powered winching
system to enable trolley-mounted stoplogs to be stored in a building that will provide protection and the ability to maintain the stoplogs.
Tilbury Lock receives ICE Award
The Tilbury Dual Function Lock Gates project has been
honoured with the Institution of Civil Engineers (ICE) East of
England Team Achievement Merit Award, for outstanding
service to civil engineering.
Acting as sub-consultants to Jacobs, KGAL completed the detailed design of the 220 tonne mitre gates
that were common to the three installed positions (inner, middle and outer gates). In the case of the outer
gates, we also provided the design of a dedicated sill support 8shot bolt9 and top level 8reverse head9
propping system, enabling the gates to be deployed to resist a ýood tide.
Chair of the ICE East of England Regional Committee, Peter Lawton, said the judges were 8particularly
impressed by the project team’s outstanding collaboration during very complex operations, often with limited
historic data and tight time constraints.’ The team were commended for exceptional planning, technical and
communication skills, delivering eûective solutions safely and sustainably under pressure.
He added everyone had 9dug deep and worked really hard on teamwork to ensure the success of the project
which was a ‘shining example’ of civil engineering at its finest.9
