St. Mary’s College, Knockbeg, Carlow

This project involves the extension and refurbishment of Knockbeg College, an historical school campus on the border between Carlow and Laois. Established in 1793 the school is the oldest Catholic post primary school for boys in Ireland. The project includes the construction of some 2,440m2 of new build, some 2,590m2 of refurbishment and the demolition of some 1,200m2 modern extensions to the various Protected Structures. The project budget includes an allowance of approximately €2.1m for the conservation, refurbishment and alternation of 4 No. protected structures including the 1780’s Knockbeg House, a 1800’s extension to Knockbeg House, a 1900’s three storey block and a 1960’s Building.

The work included significant investigation and due diligence in the existing structure including material analysis and structural assessment. Due to the age and scale of the site significant resources were applied to site investigation, CCTV surveying and GPR / Utility mapping. The project also included dry rot treatment strengthening of existing floors and roofs. The development of a new priority controlled site access junction and new car parking area for up to 50 cars is also included. The drainage strategy is based around sustainable principles incorporating permeable paving, infiltration devices and attenuation with outfall to arterial drainage. The project also involves the construction of fire water retention tanks, ball courts and play area.
