FAQs – Structural Engineer Manchester

For any work that changes the load-bearing structure—such as wall removal, RSJ installation, loft conversions or extensions—Building Control will usually require structural calculations prepared by a qualified engineer.

Costs depend on span, loads, complexity and whether a site visit is needed. See the Costs section above for typical starting fees, then send your plans for a fixed quote.

We check the existing structure, design beams/lintels/foundations, specify restraints and connections, and supply Building Control-ready calculations and drawings for your builder.

Architects handle layouts and planning; engineers design the structure that makes the design safe and buildable. Many Manchester projects need both—we collaborate with your architect.

Most small projects (e.g., wall removals/RSJ) can be turned around within 24–72 hours once we have the information we need.

Often no. We can quote from drawings and photos. We’ll advise if a visit helps.
