HEUSTON SOUTH QUARTER, DUBLIN 8
START DATE: 2014 FINISH DATE:2016 CLIENT: Lloyds Bank/Green Property Ltd.
Cronin & Sutton Consulting were the civil/structural engineers for the recent remedial works carried out to the Heuston South Quarter development including Car Parking.
Construction works ceased on the site in 2006, when a significant portion of the site was excavated to formation level for a double level basement. The perimeter pile wall is approximately 13m in height and we devised an efficient and cost-effective scheme to increase the design life of this temporary element for a further 50 years by providing supplementary anchors.
The Receiver’s appointed the site also wanted to improve the aesthetic and appearance of the undeveloped portion of the site. Cronin & Sutton Consulting reviewed the ground profile of the site and the intermittent groundwater pumping that was underway since construction works ceased. A scheme was developed where a perimeter concrete wall would be constructed at the basement edge facing the undeveloped portion of the site. This would facilitate extensive landscaping works and an increase in the ground level. An efficient structure was devised to utilise the existing elements, and ensure that the site was ‘future-proofed’.
In many areas, it was necessary to construct basement retaining elements and foundation adjacent to pile walls that had been installed over eight years ago, and had become overgrown and submerged under groundwater. In some instances the walls where next to existing buildings.
We investigated the area thoroughly and developed efficient and buildable solutions that minimised disruption to the adjoining areas and utilised existing elements where at all possible.
