Steel frames and long span
Portal frames, trusses and transfer structures, where the clear span is the whole point of the building. We size the members, then we defend them at tender.
Structural engineering
Every beam bends.
We decide how much.
Steel, concrete and adaptive reuse for commercial buildings. From the first sketch to signed drawings.

What we are engaged to solve
Five things. We turn down work that is not one of them.
Concrete and post-tension
Flat plate, band beam and PT slabs. Fewer columns on the plate, and a slab depth the developer can live with.
Adaptive reuse and strengthening
Old fabric, new loads. We test what is already standing before we add anything to it.
Facade and secondary structure
Deflection limits the glazier can actually build to, agreed before the facade package goes out.
Peer review and expert witness
Independent review of somebody else's design, and evidence when a structure ends up in front of a tribunal. About a fifth of our work, and the reason the rest of it is careful.
The curve you never see
A cambered beam leaves the fabricator bent upward. Loaded, it settles flat. Get the number wrong and the finished floor tells everyone who walks on it.
Datum shown dashed. Vertical scale exaggerated.
-
Unloaded
The beam arrives from the fabricator with 42 mm cut into it, curving upward. Sitting on the trestles it looks wrong.
-
Dead load
Frame, slab, screed. The structure takes back roughly half the curve before anybody moves in.
-
In service
Fitout, people, plant. The beam reads level, and nobody ever knows it was bent.

They gave us the camber in week one and never moved it. Two years on, the floors in that building are dead flat.
Tell us what you are building
Send whatever drawings you have, even if it is a sketch. Within a week we will tell you whether the structure works, what it costs to engineer, and whether you need us at all.
That is with us
An engineer reads it, not a mailbox. If it is urgent, call the studio on the number to the left.
