Representative engagements.

A four-storey walk-up complex presented with spalling concrete to balcony soffits and slab edges, and recurring leaks from planters over habitable rooms.

Investigation confirmed carbonation-driven reinforcement corrosion and failed planter membranes. A remedial design and specification covered concrete repair, cathodic-risk detailing at exposed edges, and full membrane replacement with revised falls and drainage.

The works were tendered competitively and delivered under an AS 4000 contract with independent superintendency through to practical completion and defects liability.

An owners corporation sought a definitive account of façade condition after fragments of render were found at ground level.

Inspection from elevated work platforms, with targeted opening-up, mapped delaminated render, corroded lintels and displaced masonry ties across the elevations. Each defect was photographed, located and classified by severity.

The report gave the committee a prioritised, costed pathway: immediate make-safe items, a staged façade rectification scope, and a monitoring regime for the balance.

A trafficable podium over commercial tenancies had leaked through successive patch repairs, with damage claims mounting below.

Diagnostic testing traced water paths to terminated membrane edges and failed movement joints rather than the field of the membrane. The remedial design replaced the system as a whole — membrane, joints, drainage and trafficable finishes — rather than repeating localised repairs.

A detailed specification and tender process gave the owners comparable prices and a warrantable outcome.

Timber-framed balconies showed deflection and decay, and glass balustrades did not comply with current loading and height requirements.

Assessment established which elements could be retained and which required replacement, with a rectification design bringing balustrades into compliance with the NCC and relevant Australian Standards.

Works were staged to keep residents in place, administered under contract with progressive inspection and certification.

Proceedings concerning widespread defects in a recently completed apartment building required an independent expert account of cause, responsibility boundaries and rectification cost drivers.

The building was inspected, the defect population organised into a Scott schedule, and an expert report prepared in accordance with the Expert Witness Code of Conduct, including a report in response to opposing expert evidence.

The structured schedule let the parties narrow the genuinely contested items and resolve the balance.
