Advanced Substructures are unique in the Western Australian
construction industry.

Our 60 years Structural Engineering experience enables faster, cheaper, bigger and safer substructures. Our designs feature in 20 successful

projects including National Excellence in Construction Award winners.

Here are some of the advantages of our designs.

Value and Speed

Our evolution of top-down construction returns maximum value and speed for our clients. The 2017 MBA National Award winner for Best Commercial Building (under $100 million) Cockburn Gateway Shopping City Stage 3 in Success used our design to deliver the entire project 25% cheaper with a 4 month time advantage over conventional techniques.

Safety from Risk


We provide the detail design of the highest risk elements (piling, footings, post-tensioning, and joints) that other Engineering firms leave to Builders. This detail gap is one of the major causes of the cracking, leakage and other substructure failures common to projects in Perth, such as seen at Elizabeth Quay Towers. We bridge that design gap.     


We extend boundary to boundary with minimised internal columns giving more parking, storage and other areas to meet planning and project requirements. Our four level deep Subi XO basement delivered all functions despite restrictions from surrounding basements and roads.

Wet Sites


We have extensive experience with creating dry substructures on wet sites. This includes in up to 8 metres of water for the State Theatre Centre of WA, recognised as the Best Overall Project in the National Engineers Australia Excellence Awards for the year of completion.

Documentation and Quality


Our documentation enables first-time teams to build directly from the plans. Our 2019 East Perth project (Skye One Seven Apartments) delivered the project in 60 weeks ahead of the 75 projected with cost savings of $620,000 on a budget of $13.6 million using a first-time builder. We are 100% locally based and back our designs with on-site Quality Assurance and monitoring.

Heritage Integration


We eliminate sheet piling and outdated retention systems, and make safe construction near Heritage sites possible. Church House is a National Excellence Award winner that was built within 100 millimetres of the oldest brick building in Perth, The Deanery, through the use of our techniques.

State of the Art Techniques


Our techniques have been subject of 2019 Masterclasses for both the Concrete Institute of Australia and Engineers Australia. They are recognised as the best in the industry and continue to develop.


New Dimensions

We enable revolutionary use of substructure areas. A 2020 Concept Design commissioned for the redevelopment of the East Perth Girl’s School features three levels of substructure with a skylit top commercial level inserted into the undercroft of the Heritage listed building. Our techniques make these new functions and possibilities a reality.

Clay Sites  


Current industry practices for treating and preventing clay movement are difficult and costly. Our Patented solutions will protect you from the risk of damage, permanently remediate cracks and prevent the requirements for expensive building maintenance.
