Structural Alterations:
This project involved adding an additional lightweight steel frame single-storey roof extension on to an existing building. Although the existing building appeared to look similar to the front elevation, it had in fact been constructed in two stages, with the original building constructed at the turn of the 20th Century, with timber floor planks spanning between rolled steel beams supported on cast iron columns and external masonry walls. The left-hand half of the building was a more recent addition reinforced structure with masonry façade to match the original building.
Back analysis was required on the RC structure, intrusive investigation was carried out to establish original reinforcement to enable this. Similarly, investigation and analysis was carried out on the cast iron columns, steel and masonry structure to the original half of the building.
