Client requirement
Overall seismic strengthening addressed torsional modes and excessive inter-storey displacement ratios in parts of a multi-storey podium.
Engineering challenge
Normal office use and rest periods had to be coordinated with extensive strengthening works and construction sequencing.
Technical approach
Anchor-reaction jacked piles, bonded steel, CFRP sheets and post-installed reinforcement were combined with overlapping work sequences.
Project value
The case demonstrates coordination of structural strengthening and construction in a public office building with continued-use requirements.
