RIVER DARGLE SITE VISIT

Aug 23, 2016

Dublin GEO has been working on the design of flood protection measures as part of the River Dargle Flood Defence Scheme in Bray, Co. Wicklow since 2014, with the overall contract value of the works designed by ByrneLooby at €4m. Approximately 1000 properties are at risk of flooding from the River Dargle and extreme tide events in the downstream tidal area of Bray. The basic principle behind the proposed flood defence scheme is containment by means of physical defences and undertaking works to the river channel to provide a hydraulically efficient solution within the existing constraints.

ByrneLooby has designed a variety of solutions to achieve the level of protection required by the EIS along 3.5km of the river. This includes embankments, sheet pile walls, reinforced concrete walls, soil nailed slopes, scour protection and dredging of the river channel.

With the works planned for completion in Autumn 2016, Dublin GEO recently organised a group site walkover. This event was attended by 12 engineers from the Dublin office who undertook a 3km walk along the riverbanks. As well as the completed works mentioned above, ongoing works seen on the day included sheet piling, installation of tie-back anchors, installation of rip-rap, construction of precast beams and construction of masonry cladding. All agreed that the experience was very worthwhile.
