Book review: Design trails: Adventures of a structural engineer

This month's letters concern Category 3 checks, subsidence on shrinkable soils and seismic design of residential structures.

Drawing on their project experience, Alice Berry, Sahil Limbu and Heleni Pantelidou share tips on how to ensure that modern methods of construction deliver carbon savings.

This month, Ron Slade has chosen a sketch by Ameet Mistry as the winner of The Drawing Board.
