This was a new build structure of around 40 tonnes. That’s fairly lightweight for a building of this size and only a single story. That said, the structure was complicated by having a double pitched roof and being curved on plan.
Our Tekla 3D modelling and drawing software allows our team to detail structures with great accuracy. We can order curved sections to be made exactly as required from CNC files, which makes fabrication quicker and ensures the final site erection goes very smoothly.
Accurate setting out and installation of the column holding down bolts is critical – especially so with a structure this complex. Again, our drawing software ties this process into the design from the start and we are able to issue very good setting out information to the groundworks contractor.

This was another vertical extension, in Farringdon, central London.
We supplied and erected a two story extension on top of a building that was already three stories high. As the building had to have its roof removed to do the works, the main contractor had to put a full scaffold lid on it making it very difficult to erect the frame with a mobile crane.
Instead, we were provided with a hoist to get all the steel sections to roof level, and we erected the frame using Genie lifts and gantry frames for the heavier sections.
On the same contract, we supplied and fitted an unusual cantilevered staircase from the basement level to ground floor.
The stair flight was formed of continuous 20mm steel plate treads and risers with non-slip nosing strip slots milled into the treads.
The whole stair cantilevered off a concrete wall, a stud wall was built a few inches in front of it to hide the fixing points, and the treads and risers were fully welded together.
As there was some welding and grinding involved in the fitting process, the stair was painted on site.
