Prince Consort Hotel

TRSC was engaged by Redcape Hospitality Pty Ltd in early 2025 under OPUS programme 010 to investigate masonry cracking on the boundary wall at 245-247 Brunswick Street and assess basement moisture conditions across the heritage-listed Prince Consort Hotel. The engagement was structured as a proactive asset management investigation rather than a reactive failure response. TRSC commenced with a visual condition survey and a before-you-dig assessment of the site frontage, identifying high-voltage cabling, medium-pressure gas main, and telecommunications infrastructure adjacent to the affected boundary. Investigation methodology included GPR scanning to locate reinforcement and embedded services, half-cell potential mapping to assess corrosion probability in concrete elements, masonry capacity calculations using historical material properties calibrated to the 1888 construction era, out-of-plane bending capacity assessment against AS 3700-2018, and earthquake loading verification under AS 1170.4-2007. Investigation findings established that the observed cracking was attributable to differential foundation movement rather than load-induced structural inadequacy, and that the unreinforced masonry walls met current out-of-plane bending capacity requirements when assessed against measured material properties. A targeted remediation design using Heli-Fix stainless steel ties was developed as a heritage-compatible strengthening method that avoids visible alteration to the protected facade, and a visual monitoring protocol was established to track wall behaviour during the ongoing refurbishment programme. RPEQ Form 15 certification was issued. The remediation cost was a fraction of the conservative wall replacement that would have been the default outcome of a less rigorous investigation.
