The inspection of the façade was completed from mobile scaffolding towers and via rope access. MEnD’s Principal Engineer Liam Holloway completed representative drops via rope access to conduct direct inspection of the typical and atypical defects.
The extent of deterioration was quantified and the risk to the structure considered in conjunction with Hocking Heritage Studio and the consulting structural engineer. A 5-year maintenance and refurbishment strategy was developed for the city. Based on the findings from the investigation.
