Structural Design & Calculations

Most domestic projects fail Building Control not because the idea is wrong, but because the structural evidence is thin. When you remove a load-bearing wall, add a storey or cut a new opening, the load that used to travel down through that wall has to be caught and carried somewhere else. Our job is to prove, on paper, that the new path works: the beam is the right size and grade, the padstone spreads the load without crushing the masonry beneath it, the bearing length is adequate, and the deflection stays within the limit that keeps finishes from cracking (typically span/360 for brittle finishes).

A complete package from us shows the loads gathered from roof, floors and walls above; the member chosen (a UB, UC, RSJ, flitch or timber section) with its section properties; the connection and bearing detail; and the code clause behind each check, referenced to the relevant Eurocode part and its UK National Annex. Where the ground is involved, foundation and underpinning design follows the same discipline. That is what lets your builder price and build with confidence, and what lets Building Control approve without a string of queries.

We size in steel, reinforced concrete, masonry and timber, and we coordinate with your architect's drawings so the structure and the design intent agree before anything is priced on site. If the drawings change, the calculations change with them, that is normal, and we would rather revise once than have a beam turn up that no longer fits.
