An engineering atelier · Est. MMXXVI
Calculations, drawings & estimates, crafted for civil engineers.
Five discipline wings, thirteen interactive studios and 435+ design calculations — sketch a frame and get a dimensioned drawing, drive a truck over a bridge, drain a retaining wall, drive a pile to set. Everything runs in your browser and exports to Excel, PDF and CAD.

“Engineering is the art of modelling materials we do not wholly understand, into shapes we cannot precisely analyse, so as to withstand forces we cannot properly assess, in such a way that the public has no reason to suspect the extent of our ignorance.”— attributed to Dr A. R. Dykes, 1946
