Structural Engineering Challenges for Sinking Foundations in Brisbane

In Brisbane, shallow footings or uncompacted fill can cause underlying reactive clays to shrink severely, especially during prolonged drought. This leads to significant foundation subsidence in older properties. The structural integrity of these buildings can be compromised, necessitating precise mapping through level surveys and geotechnical data as outlined in AS2870-2011, which ensures effective underpinning solutions are determined.

Streamlined Approvals with Brisbane City Council

Subsidence investigation report

Level survey analysis

Underpinning engineering drawings

This documentation is essential to guarantee compliance for residential foundation repairs under Brisbane City Council’s jurisdiction.

Ostanes carried out a structural integrity inspection in our home: Dr Shoja was very knowledgeable and thorough. He explained everything he was looking at and why; as well as given us lots of practical advice which was related to structural integrity and otherwise.

Ostanes were great right from the outset - they responded very promptly even on the weekend and we had the inspection and structural engineering report within two days of first contacting them. The admin staff and engineer were both very friendly, helpful and communicative - we'd be happy to use them again. Thank you!

Response from the owner:Thank you so much, Rebecca! We’re really glad we could assist you quickly and that your experience with both our admin team and engineer was a positive one. We always aim to make the process smooth, clear, and timely, so it’s wonderful to hear that reflected in your feedback. We truly appreciate your kind words and would be more than happy to help you again anytime. 𝐓𝐡𝐚𝐧𝐤 𝐲𝐨𝐮 𝐟𝐨𝐫 𝐜𝐡𝐨𝐨𝐬𝐢𝐧𝐠 𝐎𝐬𝐭𝐚𝐧𝐞𝐬 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠!

Ostanes have been fantastic to deal with from start to finish. Prompt turnaround times, great correspondence and advice. A small project for a Home Builder for a bathroom extension was made easy by their engineering know how and support every step of the way. Would highly recommend. Thanks to the whole team!

Response from the owner:Thank you, Adrian! We’re glad we could support your project with clear advice and quick turnaround. We appreciate the recommendation and look forward to helping again anytime! 𝐎𝐬𝐭𝐚𝐧𝐞𝐬 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠

We had a underpinning company quote us $10,000+ to fix an issue with our house foundation. I wanted to get a 2nd opinion and that of a structural engineer because i didn't want to pay for something i didn't need. Shoja was very knowledgeable and thorough. He checked our entire house for structural issues and concluded that the house was fine and didn't need underpinning!! They also don't carry put work that they recommend to avoid conflict of interest. I am so glad we found them, it has saved us tens of thousands of dollar of unnecessary work

Response from the owner:Lisan, we’re really pleased we could help you get a clear and independent assessment. Dr. Shoja was happy to take the time to check everything thoroughly, and it’s great to hear the outcome saved you from unnecessary work and expense. If you ever need guidance again, we’re here to help anytime! 𝐎𝐬𝐭𝐚𝐧𝐞𝐬 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠

Shoja really saved my skin with such a quick turnaround. I was buying a house and had some concerns about a crack in the render. He went next day and got me the report 2 hours later. The sellers agent met him there and Shoja abstained from telling him any unnecessary information. I would 100% use their services again and recommend them to anybody.

Response from the owner:Thank you for sharing your experience! We're so glad Dr. Shoja could assist you quickly and effectively during such an important decision. Providing fast, discreet, and professional service is what we strive for, especially in time-sensitive situations like yours. We truly appreciate your recommendation and look forward to supporting you again whenever needed!
