PWP Building Services were contracted by A.S Watson/ Superdrug on their new 500,000 sq ft (45,000m2) southern distribution centre in Dunstable, Bedfordshire, working alongside fit-out Project Managers sbh.uk.
The first task was to upgrade and extend electrical services. From the two megawatt feed and main switch already supplied, PWP extended the main panel, added a number of outgoing ways, automatic changeover equipment and a one-megawatt standby generator.
The enhanced main panel was used to feed power to 7,000m of lighting busbar, 2,600 high frequency fluorescent lights, complete with automatic aisle lighting with microwave motion detection sensors and 328 Metal Halide highbay lights. In keeping with their commitment to the environment, the Metal Halide lights were fitted with automatic detectors so they operate only when there is insufficient natural daylight, and gas fired warm air warehouse heating was installed with full trend BEMS controls and monitoring; both energy-saving features.
Other equipment and systems installed included 200 PA speakers, supplies for battery charging, sprinkler pump house supply and various installations specified by the client including vehicle wash, fuel island pumps salvage area services and comfort cooling to the existing offices.
