Client: Dunbar Garden Centre
BHC Ltd. was appointed as the main contractor for one of Scotland’s newest garden centres. Work began on the five-acre site in 2012 and was completed during the summer of 2013. The award-winning garden centre has five main departments including the unique glass building which is used to house a restaurant. Other features of the Dunbar Garden Centre include a water storage tank, silo and biomass boiler.
The garden centre is comprised of 4 portal frame type buildings with a specialised glazed coffee house and a curved roof entrance area. The main double portal sections of the building will be split into mainly open retail space, internal glasshouse, office and dry goods store.
Works began with initial groundworks over the entire 21, 000 sqm site. This included removing the existing ground cover, machining over the area for a cut and fill exercise, and importing hardcore as required. Followed by the supply and lay of 100 mm type 1 working platform over the areas designated for the building, road & carpark and turning areas.
Once initial groundworks were complete and the pad and wall foundations were in place, BHC Ltd could begin erecting the structural steel for the main section of the building – a 54 m x 42 m double portal frame building. All steelwork used within the garden centre was shot-blasted to SA 2.5 and primed with 75 microns zinc phosphate primer. The south elevation of the main building was clad with horizontal larch cladding.
The glazed coffee house area of the building was supplied and erected by Smiemans Projecten. The 350 sqm uses specialist insulated glass to ensure that the temperature could be adjusted depending on the weather. With a maximum height of 9 m, the coffee house area feels spacious even when at maximum capacity.
As the main contractor, BHC Ltd was responsible for forming access into the site including carpark, walkways & paving and a turning circle for deliveries.
Ground floor slab to the full building footprint, incorporating the screening yard was prepared to receive up fill sub base, complete with 1200 visqueen and 80 mm insulation. This was followed by a sub-base and screeds to suit the underfloor heating requirements. Areas without the underfloor heating consisted of C35 concrete. Lastly, a floor hardener and power float finish as used to ensure a high-quality finish to the floor.
