Does every concrete project need a structural engineer?

Not every project — genuinely small, non-structural work (a garden path, a small shed base below relevant thresholds) may not require formal engineering, while structural work like a house slab genuinely always does.

The dividing line is generally whether the work is structural and what specific loads or compliance thresholds apply, not project size alone — a small but structurally significant element can still need engineering input.

If you’re unsure whether your specific project needs engineering, your contractor or a building surveyor can quickly clarify this based on your project’s actual scope, rather than guessing.
