The dispute
An adjoining owner of a heritage masonry building alleged that structural cracking and movement were caused by basement excavation on the neighbouring development. The developer engaged our Registered Building Practitioner and structural engineer to assess causation and the pre-existing condition of the heritage fabric.
Matter: Adjoining owner claim against developer, VCAT
Our expert's findings
Comparison of the dilapidation survey with current crack mapping showed the majority of cracking pre-dated the works and was consistent with long-term reactive clay movement under AS 2870. New cracks were limited, hairline, and within tolerable serviceability limits under AS 3700. Vibration monitoring records were within DIN 4150 thresholds throughout the excavation programme.
Outcome
The expert report and supporting monitoring data were served on the claimant prior to the joint conclave. The claim was withdrawn before substantive hearing, with no compensation payable.
Frequently asked questions
Was vibration data relied on?
Yes — continuous monitoring from the pre-works baseline to post-excavation was compared against DIN 4150-3 limits for sensitive structures.
Did pre-existing condition matter?
Critically. The dilapidation survey allowed clear separation of pre-existing damage from any movement attributable to the new works.
