Throughout their career Institution members must continue to study and demonstrate professional development so that their knowledge and skills remain up to date.

It gives an overview of when a structural engineer may be needed, and of the value they can bring to your project. • Chapter 2 introduces relevant regulations. • Chapter 3 gives project advice tailored to a number of scenarios. • Chapter 4 gives advice on engaging a structural engineer.
