Culvert Installation, Ballinasloe, Co. Galway
This Project involved installing a new precast concrete box culvert consisting of 9 units 2.1m x 1.8m totaling 18m in length. The culvert was laid adjacent to an existing culvert on the R358 station road, Ballinasloe. A road closure and diversion was put in place to facilitate the works which were carried out in two phases in order to maintain pedestrian access for residents. The river was dammed either side of the new culvert location and the water pumped out before excavation works commenced. Sheet piles were driven in order to support sides of the excavation while the culvert foundation base was prepared and units lifted into place with 90 ton hydraulic mobile crane. There was also numerous services contained within the road including a telecoms junction box, 2 x watermains and a foul sewer line all of which had to remain operational and protected during the works.
