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).
