Financing and Contracting

The IR£70 million design and construct contract was awarded by the Cork Corporation on behalf of the National Roads Authority. The NRA received financial assistance from the Cohesion Fund of the European Union.

In the early 90s, Ewbank Preece OhEocha (formerly DeLeuw Chadwick OhEocha, and later to become part of Mott MacDonald) supervised a major geotechnical investigation, conducted a hydraulic study of the river, and carried out an environmental impact study. Ewbank Preece OhEocha, in association with Symonds Travers Morgan, produced a conceptual design and tender documents for Cork Corporation on a design and construct format based on geometric and performance specification. Thirteen parties showed interest in the contract. From these, four consortia were selected and Cork Corporation made a final contract decision in December 1994. As is typical on a large-scale project of this type, the chosen contractor was a joint venture of Tarmac Walls JV, formed by Tarmac Construction, now a division of Carillion, and P.J. Walls (Civil) Ltd., part of Ireland's Walls Group. Subcontractors then handled many of the key tasks of construction.
