Cork Prison Development

PUNCH Consulting Engineers have been retained by PJ Hegarty & Sons Limited as their Civil and Structural Engineers for the Design & Build Contract for the new €35M Cork Prison development. Construction work has now commenced on the development on the greenfield site at Rathmore Road, adjacent to the existing Cork prison. Upon completion in 2015 it will be the largest ever single investment in the prison estate.

The purpose of the development is to accommodate  a daily average of 275 prisoners  with a potential for a maximum  capacity of 310 prisoners  catering mainly for prisoners from the Cork, Kerry and Waterford areas as well as transfer prisoners from other prisons. The gross floor area of all buildings will be circa 15,072 sq. metres on a site of circa 2.64 hectares.  The secure facilities within the Development will be bounded by a circa 7.2 metre high perimeter security wall.  The buildings within the development will be one, two and three-stories high.
The development comprises of:

  • 169 Secure residential accommodation for prisoners
  • Educational, workshops, training services and ancillary facilities
  • Visiting facilities
  • Control centre
  • 7.2m high perimeter security wall as well as security fences and security surveillance and lighting systems
  • 199 parking spaces for visitors and staff (including disabled persons’ spaces) as well as 12 prison van spaces
  • Ancillary support structures and service buildings including electricity sub- stations
  • Infrastructural roads and services 

The civil engineering works include all surface and foul water drainage networks, all external roads and car parks. The engineering designs incorporate cost saving value engineering such as the elimination of part of a pumped storm water network by incorporation of a gravity drainage system, reuse and recycling of graded excavated materials in roads, carparks and paved areas.

Other sustainable measures incorporated into the engineering design include the use of SUDs and on-site attenuation of surface water run-off to minimise the impact on the existing city infrastructure. These sustainable measures are all included to compliment the BREEAM design.

The buildings are being designed and constructed using a combination of load bearing insulated precast twin-walls panels combined with masonry and steel framed supporting structure with precast floor plates and a large portal framed hipped steel roof structure.
