Case Study – Yeo Valley

Highbridge, Somerset


To meet the demand for further storage at their existing facility we were approached by the project managers to carry out a full structural engineering design service for a twin span high bay warehouse at the existing Yeo Valley Farms site at Highbridge in Somerset.


  • Recommend and design a foundation and floor slab solution for the new building
  • Design and detail the steelwork for a large twin span high bay warehouse
  • Design and detail the secondary steelwork to include a high level access walkway
  • Design and detail the storm and foul water drainage
  • External works
  • Attendances at site meetings


  • Piled foundations through a thick layer of soft silts and peat
  • Reinforced concrete pile caps below steel stanchions
  • Flared piles below the heavily loaded floor slab
  • Gas protection below the floors
  • Twin span steel portal frame with valley beams to reduce the number of internal columns
  • Suspended reinforced concrete super flat floors
  • Discharge consent for storm water flows
