HMP Liverpool is a Category B Victorian prison comprising of 8no wings, with capacity to incarcerate up to 1,370 inmates.
Whilst individual parts of the prison had undergone some form of refurbishment since the original construction, the typical standard was poor and required upgrade to meet the current MOJ and NOMS standards.
Hensall were employed on behalf of ISG to complete the specialist design, installation and commissioning of all Mechanical & Electrical services as necessary during the total refurbishment of all 8no wings, inclusive of their associated plant areas.
Works completed include the de-commissioning of all M&E systems to allow the refurbishment works to commence, subsequently followed by the installation of new systems to serve the prisoner and staff areas. Mechanical systems installed include sanitary systems, LTHW heating systems & ventilation systems, all of which are controlled and monitored by dedicated building management systems to ensure efficient operation. Electrical systems installed include LV distribution, small power, lighting, data, general alarms, fire alarms, CCTV, AV, tamper alarms, and lighting protection.
Although all works were completed within temporarily decanted wings, our project team had to work closely with the main contractors management team and prison staff to ensure works could be completed in a safe and efficient manner. Prior to commencement of the project, our team were faced with the challenge of carrying out surveys within various live prisoner environments.
