N17/N18 Gort To Tuam PPP Scheme

The Challenge

The N17 N18 Gort To Tuam PPP Scheme was separated into 3 sections, North, Middle and South.

The Rathmorrissy Interchange is the largest on the contract linking the M6 Galway to Dublin motorway and M17/M18 Gort to Tuam motorway. The roundabout itself is almost 1 km in circumference and was a very complicated and challenging aspect to the contract.

Another feature of the project was Annagh Hill Interchange, located at Annagh hill on N63. The interchange consists  4 roundabouts and approximately 4km of a road network.

The Solution

Roadstone was contracted to lay CBGM, Base, Binder and Wearing Course on both the North and Middle sections including all side roads on the Tuam By-Pass and Rathmorrissy interchange.

 

Locations

Tuam By-Pass                                                   4.1km

N17/N18 mainline                                           30km

Rathmorrissy circulatory carriageway        1km

Rathmorrissy slip roads (12no.)                    9km

Annagh Hill Interchange                                4 roundabouts+ 4km road network

Side Roads                                                         25

Safe T Certification award

In November 2016 Roadstone Contracts was awarded the highest Safe T rating possible. The audit was carried out on this project, and is a testament to the team working on the project.

 

Takeaways

Communication is key

Advanced planning and programming is vital

Dealing with issues quickly and effectively builds confidence

Quality and quality control are a key part of any large contract
