New light industrial units on a greenfield site within the existing business park for a developer on a difficult site adjacent to a railway and with an ordinary watercourse passing through the site. BDI designed the steel portal frames and foundations for the two new industrial units as well as retaining walls along a boundary, below ground drainage and hard works serving the site. BDI also designed a diversion for the watercourse as part of the development to ensure that the new development could encompass the full useable area of site.
