Quay Quarter Tower, Sydney – conservation, life extension and upgrade using live digital twinning
Bibliographic record
Abstract
This article describes the feasibility studies, investigations, analysis, structural health monitoring, digital twinning, and structural adequacy verification of the repurposed 50-storey Quay Quarter Tower in Sydney, Australia. The design life of the retained building was extended by 50 years with minimum structural intervention. The adaptive reuse increased the net lettable area from 45 000m2 to 90 000m2. The 45-year-old retained components provided structural integrity for the accelerated construction programme and 80% of the lateral strength and stiffness with minimum intervention for the upgraded building. The digital twinning technology facilitated safe and speedy construction and conserved 12 079t of embodied carbon, with a carbon footprint for the gross internal area of 247kgCO2e/m2. The innovative engineering processes enabled the client, AMP, to achieve its aspirations for a unique world-class commercial building using a comprehensive approach to reducing embodied and operational carbon.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
