When it comes to engineering, what happens below the surface is as important as what’s built on top. Every site has a unique history and set of properties which will determine the design of the proposed structure, the materials used and even the programme sequence. This history can become especially complex when working on brownfield sites or in urban or industrial areas. The presence of previous structures and proximity to industrial activity increases the risk of contaminated ground which must be assessed and dealt with before construction can continue.
