OCSC was appointed by Meath County Council to oversee the planning, design and construction supervision of the R158 Regional Road. The route runs north to south through the county linking the three urban settlements of Trim, Summerhill and Kilcock. The route is 21 kilometres in length and the reconstruction and realignment included a further 8 kilometre of local tie ins included an extended section of the R156 regional route south of Summerhill. Given the scale of the scheme, the road moves through a number of character types from rural to urban throughout its length.
OCSC specified a large area topographical survey for the scheme followed by a detailed Site Investigation Contract. OCSC undertook the Constraints Study, Route Selection and Part 8 planning for the scheme. This was followed by a significant land acquisition process involving over 170 landowners. This level of land acquisition required extensive public consultation by OCSC staff. Two separate CPO hearings were held for Phase I & II of the scheme.
The project included three river bridges across the Knightsbrook River at Knightsbrook, Dangan and Clonmahon. There were a number of extensive archaeological excavation carried out in parallel with the construction of the new scheme.
OCSC prepared the contract documents for both phases of the project and acted as The Engineer on each phase. The total construction value of the project was in excess of €35 million.
