Case study
Case study: Residential extension on shrinkable clay, Shropshire
JNM Engineering was appointed to design the foundations for a two-storey rear extension on a property with shrinkable clay subsoil and mature trees nearby. We interpreted the ground investigation report, assessed tree influence zones, and produced a piled foundation design with structural calculations for building regulations submission.
Outcome
Building regulations approval granted without revision. Piled solution avoided costly underpinning of the existing structure. Client saved three weeks compared to their previous engineer's estimate.
