The Environment Agency has said that work on the Adur tidal walls scheme in Shoreham by Sea is making good progress as a result of using silent sheet piling techniques.
Van Oord is using a Giken silent piling unit to press the piles into position, which is minimising disruption to local residents and keeping the work on track to finish by the end of the year.
According to the Environment Agency, equipment has proved to be key to working in the tight spaces between the Shoreham houseboats and the houses landside of the path.
The organisation has said that the work on the 7.2km defence structure was planned around the availability of the equipment. In total the scheme involves installed of a 2.5km sheet piled wall, along with 3km of flood embankments and 1km of concrete flood walls.
Van Oord has said that it has just completed another section of the wall with 1,176 11m-long sheet piles installed. “The work was complicated by being close to 40 houseboats along a stretch of 700m. However, we made sure to consult with stakeholders and houseboat owners keeping them informed on developments,” said a spokesperson for the contractor.
A spokesperson for the agency said: “We would like to thank everyone in Shoreham-by-Sea for their continued patience and support. More than two-thirds of the Shoreham Adur tidal walls flood defence scheme has now been completed. Having started construction in October 2016 we expect to finish by the end of this year.”
