OCSC were appointed by The Turf Club to undertake the redesign of the R413 regional road at The Curragh County Kildare. The road was to be realigned over a length of approximately 1 kilometre in order to accommodate the redevelopment of the Curragh Racecourse along with new hotel and stand facilities. The works included the design and site supervision of the 1 km of single carriageway approximately 1.0 km in length along with boundary treatment to adjoining lands. The carriageway was provided with kerbs, footpaths, cycle paths, line markings, signage and guard rails, together with the full range of services and utilities, including foul and surface water drainage, water main and telecoms.
The scheme included a significant length of tunnel beneath the new road – 35 metres in length. This reinforced concrete tunnel with headwalls and underpass (11.5 x 35 metres) was designed to allow access from the stables to the curtilage of the racecourse. Given that the tunnel was to accommodate thoroughbred racehorses worth sometimes many millions of euro, the detailing of the tunnel and approaches were of critical importance. As the tunnel was the first of its type in Ireland OCSC had to carry out extensive research included research in a number of international racecourses in order to ensure that the appropriate structure was provided.
OCSC provided all civil, structural, environmental and transportation engineering services for the development from preplanning meetings with the planning authority through to detailed design, contract documentation and site supervision.
