— Built Heritage Assessment

Redleaf Group was engaged by RMA Engineers to conduct a detailed cultural heritage assessment of the Charlton Stone Culvert, constructed ca. 1860s, beneath a decommissioned railway embankment at Charlton, Queensland. The assessment was performed in line with the Queensland Heritage Act 1992 and the Australia ICOMOS Burra Charter (2013) and included onsite inspections, structural and condition analysis, comparative heritage evaluation, and legislative compliance review. The stone culvert is a rare and intact example of early railway infrastructure, comprising bluestone blocks, brick arch roof, and convict-picked sandstone finishes, possibly associated with Queensland’s first chief railway engineer, Abraham Fitzgibbon.
