Securing a contract for a 5m diameter, 4m rise, helical staircase to be installed nearly 5,500km away from our Nottingham workshop in the tallest commercial building on Bermuda was quite a feat; building and installing it was quite another.
Tendering against both British and American metalwork companies our initial success was accomplished with our pro-active attitude to developing the architect’s design concepts and our confidence in engineering the structure.
The architect's specification was challenging; other than fixing points at the bottom and top, there was to be no additional structural support: Once installed there was to be no movement or deflection in the staircase.
Once the structural drawings were approved, the CANAL team fabricated the staircase in the works factory and tested it for movement before dismantling it piece by piece, packing it in crates and shipping it the 5,500km to Bermuda.
On site, the CANAL team had no time to enjoy the Bermudan sun, as piece by piece they reconstructed the feature staircase, welded it all in place to create the seamless masterpiece.
