OCSC win award for engineering consultancy on Luas Cross City
O’Connor Sutton Cronin are proud to have been announced the winners of The Public Sector Magazine, Excellence in Business Awards 2017 for Engineering Consultancy Transport, Luas Cross City Project.
The New Luas Cross City project serves a 5.6km long corridor from the Luas Green Line at its current terminus (St. Stephen’s Green) to the Iarnród Éireann Broombridge Station on the Maynooth railway line. The scheme links Dublin City Centre to Phibsborough and Cabra via Broadstone and Grangegorman and will provide a fast and reliable commuter service to the city centre, greatly enhancing the connectivity of the whole rail based public transport network. Passenger services commenced on 9th December 2017.
OCSC established a special team in-house to deliver our portion of the project and were responsible for the structural and building services design of the Main Depot, sanding shed, wash plant and sub-stations. Our Bridge Engineers designed the new top-down Broadstone Gate Bridge as well as the repairs to the old railway bridges at Cabra Road and the North Circular Road. Our Structural designers also designed the underground technical rooms at College Street and O’Connell Street as well as all 13 stations. Our drainage team have designed the public and private surface water and foul systems including major attenuation structures, relining of existing sewers and replacement of sections of the Bradogue River culvert. Our road and carriageway design teams have designed the reinstatement of the city streets and footpaths affected by the track slabs. Our public lighting teams have designed the areas of new lighting to be included in the works.
One of the most difficult aspects of the project has been the avoidance of existing buried services and we therefore created a special team to deal with the insertion of the required Luas ducting and track slab around these utilities.
OCSC have modelled the traffic aspects of the project and developed this into the completion of required documents for Dublin City Council.
Our involvement also included assessing the condition of O’Connell Bridge and designing the new track slab and road to respect this important piece of our heritage.
