Arla Foods Warehouse Extension – Westbury, Bath

JPG were appointed as consulting engineers for a phased redevelopment and extension to the existing Westbury Dairy in Wiltshire.

Phase 1 involved internal modification to adapt the existing processing area with the provision of new internal drainage within the existing building. Also under this Phase, and to facilitate the Phase 2 works, new external plant rooms and two-storey substation buildings were constructed. These buildings were supported on traditional spread foundations. The existing silos were required to be relocated and constructed on new piled foundations. Significant external galvanised steel pipe gantries were constructed to allow both building services and process services to be distributed.

Phase 2 comprised an extension to create a new butter manufacturing facility incorporating a process hall, packaging area and cold store. In the process area, due to the need to support and distribute significant services, a steel truss roof was chosen allowing all services to be placed above the hygienic ceiling line. Significant below ground stainless steel drainage was provided to suit the client’s bespoke layout, which formed part of the effluent system. Ground slabs were laid to falls – again to suit the client’s process layout.

Over the packaging area long steel span steel cellular beams were chosen to support the first floor plant room. This enabled the area to be column free to aid the automated packaging machine layout below.

The cold store was designed to support high bay racking for the distribution of products.
