ECI M8, Cashel Mitchelstown

CASE STUDY

The Cashel to Mitchelstown project, awarded to Sisk and our JV partners is the first Early Contractor Involvement (ECI) scheme in Ireland. ECIs were part of an initiative arising from Sir John Egan’s work on the New Engineering Contract (NEC) to improve contracts and involve contractors earlier in the tendering process.

The scheme comprises the design and construction of approximately 37km of dual carriageway together with various drainage culverts and drainage systems, four interchanges, side roads, link roads and accommodation roads. The structures comprise 19 overbridges, 12 underbridges, six river crossings, seven accommodation bridges, one rail crossing of the Waterford to Limerick line and 34 PCC box culverts.

The earthworks were designed as a balanced cut and fill operation, utilising all the suitable material from major cuttings to form the required embankments throughout the project. The project was a 50:50 joint venture with Roadbridge Ltd.
