A structural engineer, as the name stands, is an engineer who specialises in the structure of buildings. They determine the strength and durability of a structure – i.e a building – and are a key professional in the construction process. They’re able to assess the safety of a building and renovation projects will provide specifications and calculations for the design, as well as suggesting building materials. There are many types of structural engineer with experience of working on a huge variety of structures. For a home renovation or inspection, you’ll need to hire a structural engineer with experience of residential work. Your engineer is likely to be a member of either the Institution of Structural Engineers (IStructE) or the Institution of Civil Engineers.
