Dawnus Construction were awarded Phase 3 of the West Rhyl Coastal Defence Scheme as part of the major upgrade to the town’s sea defences to protect the 1700 properties against flooding by Denbighshire Country Council.

The £5.45m scheme comprised of an extension and improvements for the existing promenade with enhanced public realm, pedestrian and cycle routes and the construction of primary and secondary defence walls.  Due to the coastal works encroaching on to the existing beach by approximately 40 meters, some of the work activities were carried out under tidal conditions, with controlled assessments to all beach and tidal works.

The flood defence is 470 meters in length and required standard protection designed for a 1 in 200 year storm with an allowance for 50 years of climate change.

The initial design was for a stepped revetment construction but was rejected by the Welsh Government for funding and a new design was approved using Marshalls Civils and Drainage Redi-Rock modular walling blocks.

The construction of the coastal project has now been completed with the flood walls being successfully tested during the storms and high tides of November/December 2015.

The project has since been shortlisted for an ICE Wales Award
