Shanco delivered a full groundworks package to enable the expansion of HMP Sudbury, for modular contractor ESS. The project included over 2km of services installed across the Category D prison site to support the overall expansion works. This scheme was part of the Ministry of Justice’s 20,000 places capital expansion programme, a critical national infrastructure project.
Planning and Coordination
The project also included foundations for the Rapid Deployment Cell block, generator bases and foundations for a new substation. EL1 clearance was required for all operatives, which Shanco maintains as a minimum for all of our workforce.
The installation process began with a number of preconstruction stage meetings with the client, M&E contractors and representatives from the Establishment to establish a clear route for the new services prior to work starting. After surveys, Shanco produced detailed site drawings aligned with the prison’s access, security and prisoner movement restrictions, supporting business as usual during the works.
Overcoming Challenges
As with all prison projects, there were numerous challenges that arose throughout delivery. During surveys, Shanco encountered existing services and culverts that were not identified in the preconstruction GPR survey. This required careful coordination with utility providers to reroute existing services and avoid disruptions to the Establishment’s operations.
We also identified asbestos in some of the working areas, necessitating specialised procedures and safety measures to contain and remove it according to the Control of Asbestos Regulations. The new service route crossed a mixture of soft and hard landscaped areas, including the main access road through the facility, meaning a carefully sequenced route was essential to ensure access was maintained 24/7.
Successful Project Completion
Despite the strict security restrictions and unique obstacles faced, the project team successfully completed the project on time. Through proactive planning, effective communication, and continual adherence to safety regulations, the site-wide installation was carried out to the client’s satisfaction.
Through proactive planning, effective communication, and adherence to safety regulations, the site-wide installation was carried out efficiently, ensuring minimal disruption to the prison’s daily operations. By adhering to the agreed-upon route and effectively managing unexpected obstacles, Shanco demonstrated their problem-solving expertise and commitment to meeting the project’s objectives, while maintaining high standards of quality and security.
