Working with Scottish Prison Service (SPS) and its design team of TPS Consult and Morgan Sindall Group company Baker Hicks, Morgan Sindall Construction fully developed the initial scheme concept on a design and build basis and the new facilities were constructed over three phases.
The 72-week first phase provided a new regimes facility comprising kitchen, laundry, workshops, classrooms and ancillary services as well as a new energy centre. This was followed by the delivery of an exemplar 284-cell houseblock accommodating double, buddy and disabled cells and staff quarters as well as a new health centre, prison reception and gymnasium.
The programme was completed with the handover of a new visitor centre and an estates and stores building featuring offices, storage and welfare services.
Specialist services included sophisticated fire detection and alarms, mechanical ventilation and heating, plus water services. Tamper-proof and vandal resistant power, data and lighting were also installed in prisoner occupied areas.
A Monodraught Windcatcher balanced flue system was installed to provide natural ventilation. This reduced operational and maintenance costs by removing the need for an extensive air conditioning system.
HMP Perth was the first prison to use an innovative ‘flat-pack’ precast concrete superstructure reducing the potential for on-site waste. Using such a technique for the four-storey houseblock provided more flexibility than a conventional modular system, which ultimately led to a cost saving of approximately £500,000.
- Due to working within the constraints of the existing prison boundary, ‘bubble’ sites were created to isolate the works from the live prison
- Ensure the phasing strategy met the security needs of the prison
- Completing projects on time within strict operating hours and access restrictions
- Dealing with the discovery of human remains on the site through close collaboration with archaeological consultants.
