Steria was appointed to assess the existing portal frame structure of an office and commercial unit in Suffolk. The brief focused on reviewing the structure’s capacity to support upgraded roof insulation panels and new roof coverings as part of an energy efficiency improvement programme.

Our engineers carried out a detailed inspection of the existing frame and evaluated the current roof loadings to determine whether the existing coverings could be retained or would require full replacement. Structural implications were carefully analysed to ensure the proposed upgrades could be safely accommodated without compromising the integrity of the building.

The resulting recommendations provided a clear strategy for upgrading the roof system in line with current design standards, allowing the client to move forward confidently with a sustainable and compliant refurbishment.
