The project includes a bypass of Waterford City in the southeast of
Ireland and a network of other connecting roads. In total there is
22.6 km of dual carriageway, and 16.2 km of single carriageway
links and side roads. The project includes a 465 metre long dual
carriageway cable-stayed bridge over the River Suir (with a 230m
main span), plus a number of major viaduct and grade separated
interchange structures totalling over 50 bridges.
Mott MacDonald was involved from a very early stage of the project
and was appointed to carry out an initial feasibility study in
1996. Our role has subsequently included Constraints Studies, Route
Selection, Environmental Impact Assessment (EIA), Toll Studies,
Navigation Studies, and Geotechnical Investigations as well as
Statutory Oral Hearings and Sworn Public Inquiries for Compulsory
Purchase Orders (CPO), EIA, Bridge Order, and Toll Order. The
approval of the project was followed by contract document
preparation as a PPP project, tender assessments, and
administration of the contract including assessment of the PPP
Company’s design & construction submissions. We also provided a
dedicated Site Monitoring team during construction and we are still
providing some advice during the Operation and Maintenance
Key Success Factors:
The scale of the project and its successful delivery in the face of
many significant challenges.
- The development, guidance and management of the project from
concept through alternatives, statutory processes, procurement, and
- Dealing with the discovery of Viking remains and the need to
find a new route around the designated national monument site in
Woodstown was a significant part of the project resulting in
partitioning of the main contract and simultaneous route selection
and statutory process to find a new route.
- The number scale and complexity of structures on the scheme
including the longest span bridge in the country.
