Location: Dublin, Ireland
The Four Courts is a nationally significant historic building in Dublin, requiring sensitive engineering interventions to protect both structural integrity and heritage value. McFarland Consulting Ltd were appointed to undertake a structural assessment of an intermediate reinforced concrete slab and to implement measures to manage ongoing deterioration risks.
MCL carried out a detailed structural assessment of the slab to establish its condition and performance. To support ongoing evaluation of structural behaviour, wireless remotely accessed crack monitoring sensors were installed at key locations. These sensors enabled continuous monitoring of crack activity, with data reviewed and reported on at regular intervals.
In addition to monitoring, MCL designed and installed a hybrid sacrificial anode cathodic protection system to provide corrosion protection to reinforced concrete supports located within the dome structure. The system was selected to suit the sensitive environment and to minimise visual and physical impact on the historic fabric of the building.
The combination of structural assessment, continuous monitoring and targeted corrosion protection provided a robust, long-term approach to managing deterioration risks. The works have supported informed decision-making and contributed to the continued preservation and safe use of this important heritage asset.
