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!

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!

What services does Ostanes Engineering offer?

Ostanes Engineering provides structural engineering design, project management, structural inspections, ancillary structures certification, retrospective approvals, and forensic engineering. We work with residential, commercial, and industrial projects across Australia to ensure compliance, safety, and durability.

Retrospective certification is required when a structure has been built without prior approval. Our engineers assess the existing structure to ensure it meets Australian Building Standards, and we help obtain the necessary approvals for compliance. This is essential for Class 10 shed conversions, home renovations, and commercial structures.

Converting a Class 10 shed (non-habitable) into a Class 1 dwelling (residential use) requires structural modifications, insulation upgrades, and compliance with fire safety standards. Ostanes Engineering provides retrospective certification, extension engineering design, and council approval guidance to ensure a legal and safe conversion.

Forensic engineering involves the investigation of structural failures, defects, and material issues. This service is essential for insurance damage reports, legal disputes, and compliance cases. Our experts conduct on-site inspections and testing to identify the root cause of failures and recommend certified remedial solutions.

Yes, a pre-purchase structural inspection helps identify hidden defects, foundation issues, and wall crack movement that could lead to costly repairs. Our team provides detailed engineering reports to help buyers make informed decisions before finalizing their purchase.

Ancillary structures like carports, decks, patios, verandahs, swimming pools, and retaining walls must comply with Australian structural and safety regulations. Ostanes Engineering ensures these structures meet all required load-bearing, wind resistance, and Form 15 compliance standards.

A dilapidation report documents the existing condition of nearby structures before and after construction or demolition work. This protects builders and property owners from potential damage claims. Ostanes Engineering provides comprehensive pre- and post-construction condition reports for legal and council protection.

We provide expert engineering reports for Queensland Building and Construction Commission (QBCC) and Queensland Civil and Administrative Tribunal (QCAT) investigations. Our forensic engineering investigations assist in cases involving compliance disputes, roof defects, and structural failures.

As a proudly Australian-owned and operated company, Ostanes Engineering understands local building regulations across Queensland. We offer tailored structural design solutions that ensure compliance with Australian Standards (AS 1684, AS 3600, AS 4100, AS 4678, AS 1926, and AS 4055).

You can contact Ostanes Engineering via our website, email, or phone to discuss your project needs, request a structural inspection, or get a detailed quote. Our team will guide you through the next steps to ensure a smooth and efficient process.
