The Dartford Creek flood Barrier forms part of an extensive flood protection scheme providing protection to around 2000 residential properties and over 750 commercial properties in and around Dartford.
The Environment Agency appointed Halcrow to carry out an evaluation of the whole scheme including appraisal of the Health & Safety, Environmental, Economic and Operational needs of the flood barrier structure to justify a minimum further 25 years period of protection.
Halcrow nominated KGAL as specialist sub-consultant to evaluate the operating system for the existing twin leaf, vertical lift gate barrier.
Each gate leaf weighs around 150 tonnes and is suspended on synchronised roller chains, lifted and lowered by electro-hydraulic winches.
