This project consists of an extension to the existing Brisbane Youth Detention Centre with the provision of mechanical services to five (5) buildings including Accommodation, Kitchen, Laundry, General Learning and Maintenance buildings. The construction works was carried out within a “live” correctional centre that continued to operate at full capacity during the ACDC extension. The mechanical services comprised of a combination of chilled water fan coil units, and DX systems to provide air conditioning as well as smoke exhaust control to the accommodation building. VAE were also contracted under the ACDC project to install the underground Chilled Water (CHW) ring main to the neighbouring New Youth Detention Centre (NYDC) project.
