Heritage Building Assessment

Heritage buildings require investigation approaches that preserve original fabric while delivering definitive technical data. SiteOps specialises in non-destructive investigation of heritage-listed structures — using GPR, LiDAR, and thermography to understand structures without invasive testing.

We work routinely without original drawings, assessing materials that have never been formally characterised — sandstone, limestone, lime mortar, wrought iron, early steel, and pre-standard reinforced concrete. Our approach starts with the presumption that original fabric is valuable and intervention should be minimal.

SiteOps provides heritage asset owners with a seamless journey from investigation through to remediation recommendations and long-term monitoring. 3D LiDAR scanning produces complete as-built documentation where none exists, providing the geometric basis for all subsequent technical analysis.

Heritage investigation demands particular expertise in interpreting construction systems, material behaviour, and deterioration mechanisms that differ fundamentally from modern construction. Lime mortar acts differently from cement mortar. Wrought iron corrodes differently from modern steel. Early concrete was mixed and placed differently from today. SiteOps brings this knowledge to every heritage investigation.

Heritage projects also carry an approvals dimension that ordinary investigations do not. For buildings on the Queensland Heritage Register, any work touching significant fabric needs approval before it happens, so SiteOps prepares a Heritage Investigation Method Statement that sets out exactly what will be done, where, and how the fabric will be protected and reinstated. We coordinate with heritage advisors and conservation architects so the investigation aligns with the building Conservation Management Plan and the Burra Charter principle of minimum intervention.

The output is designed to serve the whole heritage lifecycle. A 3D LiDAR scan becomes the permanent measured record of the asset, useful for conservation planning, adaptive reuse design, insurance, and disaster recovery. Material characterisation tells the engineer what they are actually working with so repairs use compatible, reversible materials rather than modern products that can accelerate decay. Long-term monitoring then protects the building through nearby development or as known movement is tracked over the seasons, giving custodians evidence-based confidence in how the structure is performing.
