Preliminary estimates of the cost of providing various services to the Thornton Hall site were prepared as part of the site evaluation process which was carried out by engineering consultants prior to the decision to purchase the site. The report estimated the cost of providing various services, such as mains water, foul sewer, and power including gas and electricity to the site at approximately €8.5 million.
On the question of road access, the existing road serving the site has been assessed as adequate by the engineers engaged to carry out the site evaluation. However, they recommended some improvements to and upgrading of the road which is currently being examined by a team of technical consultants appointed by the Prison Service. Consultation will take place with the appropriate authorities in due course.
