- Design and construct of the electrical and dry fire package
- Installation of 2x 1000kVA substations and associated infrastructure
- 500kVA Generator installation and associated infrastructure and Switchboards
- UPS Installation for backup of critical security and comms equipment within all new buildings
- Light and Power installation including associated DBs and sitewide underground infrastructure
- 2x new 1600A MSBs
- PFC Equipment
- KNX Lighting control with sitewide override from New Main control room
- Dry fire detection and BOWS including incorporation of existing system to new system.
- Stage 1 Included the fit out of an existing building on site to house inmates whilst works to construct the new buildings took place.
- Stage 2 involved the demolition of six existing cottages and re-diversion of services to allow the construction stage to proceed. This involved the design and construct of three new 48 bed minimum security blocks, 1x segregation unit and a new multipurpose wing. Also involved during this stage was the complete design and construct of the new gatehouse building and associated infrastructure including HV works and generator installations for the new supply infrastructure for the entire centre.
- Stage 3 of the build resulted in the demolition and re-diversion of services of the last four cottages to make way for the new construction to proceed. This stage consisted of the design and construct of the two new 48 bed medium security blocks and the demolition of the old gatehouse building to make way for the design and construct of a new reception/admin building in its place. The overall design also allows for the infrastructure for four future blocks to be built and connected.
- Construction was undertaken in and around an operational prison, creating many challenges as work could not impact prison security. Due to new infrastructure, many LV and HV shutdowns were required, resulting in the detailed design of critical equipment to ensure a smooth transition from old infrastructure to the new network. Kerfoot spent many months co-ordinating with services including security, CCTV and access control. This involved interaction with all major stakeholders of OMMPCC and co-ordination with the John Morony and Dillwynia facilities which also share the site. All works required the approval of the Governor prior to being able to proceed.
