Knights Brown has been appointed underneath a two level design & construct contract for the £29.4m Poole Bridge to Starvation Hill flood defence scheme.
The infrastructure has been designed no longer simply to give protection to the realm from tidal flooding but in addition to make stronger its long-term regeneration.
Delivered in partnership with Bournemouth, Christchurch & Poole (BCP) Council and South West Flood & Coastal, the scheme will supply 1.5km of continuing flood defences alongside the jap aspect of Holes Bay.
Development starts this month at the stretch between Holes Bay Trail and Lifeboat Quay), the place the peak of the pathways will probably be raised to two.65 metres AOD (above ordnance datum – or above sea stage in previous cash) through upgrading embankments and rock revetments.
Paintings at the stretch between the RNLI automobile park and Poole Bridge is because of get started within the autumn and can contain a three.6-metre AOD metal tubular and sheet-piled wall with flood gates. Each zones will take roughly 18 months to finish.
Because of salt marsh and dirt flat ecosystems that make stronger wintering wading birds and wildfowl, Holes Bay is designated as a Wetland of Global Significance (underneath the Ramsar conference), Particular Coverage Space and Web site of Particular Clinical Passion. To give protection to marine natural world a bubble curtain will probably be put in to verify any sediment disturbed whilst paintings is underway is successfully contained. An ecological engineering methodology that includes pole and pontoon hulas will probably be put in at key places to extend marine biodiversity.
Matt Hosey, head of flood and coastal erosion possibility control at BCP Council, stated: “For years, it used to be expected that the continued regeneration from Poole Bridge to Starvation Hill would lead to complete flood defences. On the other hand, contemporary tendencies have simplest delivered them alongside remoted sections, leaving important gaps. This incomplete protection exposes the broader space to tidal flooding, a possibility that can building up in frequency and severity because of local weather alternate. South West Flood & Coastal has been actively progressing the supply of this crucial, primary and complicated flood defence scheme, securing considerable investment contributions from Setting Company Grant in Assist and BCP Council Strategic CIL [community infrastructure levy]. Thru early contractor involvement, Knights Brown has contributed to improving the scheme’s buildability, shortening the development programme and value-engineering prices, all whilst aiming to scale back environmental affects.”
Knights Brown divisional director Mike Criminal stated: “Our in depth revel in in coastal and marine civil engineering extends throughout southern England and Wales. This comprises tasks such because the North Portsea scheme the place 1.9km of flood defences are recently underneath building; a 1.2km concrete confronted, stepped apron and sheet pile toe wall simply finished at Mumbles, South Wales; and the Falklands Jetty improve at Marchwood Port in Southampton.”
