Our scope of works was to provide drawings for additional roof members at Marylebone underground station in central London.
Unlike many new build projects where we work with theoretical dimensions & sizes, this was a retrofit contract to some much older metal work. We therefore had to be furnished with the original roof drawings to design the new members around. To ensure that the existing roof was not damaged, all new steelwork had to have neoprene isolation at any contact area and to reduce the weight applied to the existing structure. New members were supplied in a mix of mild steel & aluminium as per the client requirements.
