Mott MacDonald will design the scheme, which is the second-largest sea defence project in the country and will cover a 5km stretch from Clacton Pier to Holland Haven, protecting nearly 3,000 homes for the next 100 years.
Acting on behalf of Tendring District Council, Mott MacDonald wrote the project appraisal report that secured the £36m funding. This includes matched partnership funding from Tendring District Council and Essex County Council, as well as other contributors.
The consultancy is now providing detailed design of the scheme which includes 24 rock fishtail groyne structures and nearly 900,000 cubic metres of beach recharge.
The consultancy is also undertaking numerical modelling for the wave conditions and sediment movement and will be responsible for gaining planning consent, licence approvals and stakeholder engagement, as well as environmental assessments, ground investigation procurement and supervision and third-party funding.
Peter Phipps, Mott MacDonald’s project director, said: “The detailed design will incorporate sustainability as much as possible. The rock groynes will require excavation of the London clay platform to ensure stability and this material will be placed under the beach recharge to reduce on-site waste. The existing concrete and timber groynes on the frontage will also be reused or recycled where possible.”
Mott MacDonald’s design is due to be completed by 2014.
