Working from a number of 2D CAD drawings from the Architect and Engineer we constructed a concept model in 3D in order to highlight some areas that needed further discussion and agreement on. As there were 2 different finishes on the staircase - Portland Stone on the lower section and Timber on he top, it was vital that the core steel structure made allowances for the different depths on finishes to maintain an equal rise throughout the finished staircase.
Once confirmation was received to proceed, a full set of fabrication drawings were created and approved.
