Rotork are a manufacturer of gears, controls and actuators who have a world-leading factory located in Bath, which acts as the focal point for their worldwide operation. They purchased an old industrial building next to their existing factory in order to expand their business.

The old building had two floors and was previously used as a call centre. Next to the main building was an adjacent warehouse, connected on the east facade. The project brief was to refurbish the entire building and to replace the roof of the warehouse in order to increase the storage volume.

BJP were responsible for the full design of the M&E services. The design was extremely difficult. The roof of the main office building was unable to support the weight of any services, including pipework and cable tray. The ground floor of the building had an equipment testing area with a ceiling mounted crane system. Great care was needed to avoid any clashes with services. The entire office was to be cooled but VRF style air conditioning was unacceptable to the client.

BJP designed a system using floor mounted four-pipe fan coils for heating and cooling, wall mounted heat recovery units for ventilation and high level convection heaters in the warehouse. Power and data in the office areas was designed without the need for visually intrusive power poles despite the constraints on service runs. Specialist scene lighting was used in the boardroom. Detailed coordination of service runs was required to ensure that there was sufficient space and that services would be hidden wherever possible.

The server system for the new building was to act as the central point for Rotork’s entire operations worldwide. Because of the importance of the IT area close control of temperature and humidity was needed. An uninterruptable power supply was added to ensure the server would be kept running in the event of a power failure.

The building is located close to the river Avon. Although the risk of flooding was not thought to be significant the server had to be kept running even during a flood. The outdoor condensers were therefore raised to avoid any potential water damage. The power circuits were designed to allow a generator to be used to feed the server and associated close control units only.

In addition to the services outlined BJP designed the hot and cold water system, fire alarms, utilities and a ‘Red Wall’ perimeter security system.

BJP worked closely with the client and contractor during the construction period to ensure the building was delivered on time and on budget. At completion the previously decapitated building had been transformed into a stylish modern office and efficient storage facility.
