The construction of the Port Botany Expansion project meant the contractor had to fulfil stringent design criteria, specified operational loadings and complex geo-technical conditions that combined to demande a high level of innovative design and modelling.
A number of cutting edge design solutions were developed during the design phase that was integral to the overall success of the project. These included:
•    Improved counterfort design;
•    Iterative soil-structure design;
•    Vibro-compaction methodology;
•    Continuous cope beam design;
•    Seismic design solution;
•    Radial precast yard methodology;
•    Patented tie bar system;
•    Concrete mix design;
•    Integrated temporary works design;
•    Counterfort movement transporters and barge. 
The innovations established by the Baulderstone management team in delivering the Port Botany Expansion project have demonstrated the very best of the industry’s skills in delivering this demanding project.
