Case Studies

centre:mk, Sunset Walk

Having built up extensive knowledge and experience in the retail sector by working on many projects of different scope and size at a number of UK shopping centres, Rolton Group were appointed by Princebuild Limited to provide multi-disciplinary engineering services for a multi-million-pound refresh project at centre:mk.

Our engineers provided mechanical, electrical and structural detailed design services for this project, comprising of the refurbishment of Sunset Walk, Acorn Walk, Silbury Arcade and Midsummer Arcade, creating a high-end shopping area within centre:mk, differentiating it from the rest of the centre.

This involved installing an all-new LED lighting scheme, including bespoke suspended hexagon luminaires throughout the malls, suspended sculptures within the high-level entrances, raising the ceilings and new “pause” seating areas throughout the mall spaces.

Modifications to the design of the ceilings have also allowed upgrades to the sprinkler system, fire detection and alarm system and CCTV. Additionally, new floor access chambers are to be installed to provide power and data for commercialisation units.

In terms of structural works, our engineers carried out onsite inspections at high ceiling level to verify and amend record information of the existing steel frame members. The existing frame was checked for capacity to support the new hanging sculptures at the North and South Sunset Walk entrances.

New steelwork was designed and detailed to support the new entrance doors and glazed canopies at the North and South Sunset Walk entrances, plus several entrances along Acorn Walk. As part of these works,

Rolton Group also provided the required steel members for the new Rimex-clad entrance frames, which required mid-air suspension whilst not affecting the existing shop fronts.

In terms of mechanical and electrical services, our engineers had the responsibility of designing a number of upgrades to the building services within the centre. New heat pump air curtain systems have been designed to replace the existing system to the four entrances. A new IP-based CCTV system has been designed with improved coverage. The fire detection and voice alarm systems have been designed to better comply with current standards.

Our engineers have also designed low voltage electrical distribution systems to provide electrical supplies to the new services from the four plant rooms and a cold water service to the new champagne bar. A new lighting control system has been designed to integrate with a new Build Management System (BMS). Lighting is to be supplied from a busbar trunking system, concealed above the ceilings.

Existing network infrastructure for gas and electricity was discovered and needed to be concealed within the existing ceiling, which posed a challenge. Designs for diverting these services was undertaken.
