Hayes Higgins Partnership acted on the development of this 13 acre commercial development for Dunnes Stores anchor tenant as Civil Structural Engineers with responsibility for all siteworks, access roads and N52 access roundabout and associated works.

Hayes Higgins Partnership provided services as follows:

  1. Traffic Impact Analysis

  2. Road Safety Audit

  3. Highways Design

  4. Highways Structural Design

  5. Structural Design of 2,500m2 of piled bridge

  6. Supporting roundabout and approach road over peat

The site overlays 6.0m to 9.0m of peat and soft clays. The focus of our service was in determining the appropriate design for the paved areas designed to carry the vehicular traffic

In the carparking areas a system of super-loading the peat / clay is to be implemented to induce 500mm of settlements. Differential settlements are controlled by geogrid / geotextile composite reinforcement placed in capping layers.

A 300m long bridge was designed on piles to bridge a soft spot at the access roundabout. The bridge design incorporates a system of vertical and raking piles to resist horizontal pressures induced by settlements of adjoining developments which are supported on compressible peat and clays.
