This project, though relatively small due to the limited erf size, was a challenge in that a vaulted roof with central gutter was required with the internal space requiring the vaults to be fully unobstructed.
Our solution was to use rolled steel angles to keep weight and costs down utilising reinforced concrete support columns and central gutter that stabilise the arch against lateral forces from external wind and inherent thrust from the arch shape.
