Can I use the same engineer across multiple stages of a project?

Yes, and it’s genuinely worth doing where practical — one engineer carrying design intent across your slab, retaining wall and any later extension means fewer handover gaps and a genuinely more consistent understanding of your site’s conditions.

There’s no requirement to use the same engineer throughout, but changing partway through often means paying for the new engineer to re-familiarise themselves with your site from scratch.
