The Sorting Office, Cardiff Lane

The Sorting Office, Cardiff Lane

The Sorting Office is located in Dublin’s North Lotts and Grand Canal Dock Strategic Development Zone, a regenerated city quarter which is home to a number of international technology companies such as Facebook and Google.

The development - being undertaken by Marlet Property Group - includes the construction of 56 residential units, 12,000 sq ft of retail space and 202,000 sq ft of office space across 7 storeys plus a basement.

The Sorting Office, Cardiff Lane

Our Role

The Sorting Office development site was considerably contaminated due to former uses of the dock area. The design solution, detailed by the engineer, involved the installation of a 1m wide diaphragm cut off wall to attenuate the contamination on site in order to prevent migration off site, potentially negatively impacting the nearby River Liffey.

Ayesa value engineered a bespoke design solution to reduce the construction programme and costs of constructing the cut off wall, detailing a cement-bentonite cut off wall which could be constructed using standard CFA piling techniques in a secant arrangement. Detailed testing and compliance inspections ensured the scheme was completed to the highest standards, with the required permeability and depths achieved to ensure the contamination is attenuated on site over the design life of the scheme.
