Work on the first phase of the Madeira Terrace restoration may not be complete by next summer as hoped. A small number of the cast iron elements of the terrace have not passed initial stress testing, which means further tests are now being carried out. “The design [of the terrace] is quite robust, it’s just whether the material stands up to that. “We have had some issues with cast iron strengths not coming up to strength and that means further testing and potentially strengthening up of those items. The restored structure has been designed to be robust for at least 60 years, and hopefully far longer than that – assuming regular maintenance.
