TOOWOOMBA REGIONAL COUNCIL BUILDING CONTEXT

Navigating Toowoomba Regional Council Regulations

Structural engineering documentation is one part of the Queensland development and building-approval process.

1. Structural Engineer (RPEQ)

The engineer assesses structural loads, support conditions, existing construction and site constraints, then prepares the drawings, calculations, design certificate or technical report included in the agreed scope.

2. Private Building Certifier

The certifier assesses the building application, determines whether approval is required, establishes the inspection schedule and confirms the certificates and supporting documents needed. The structural engineer does not issue building approval.

3. Council & Planning Referral

Toowoomba Regional Council administers its planning scheme, property records and relevant local referrals. A town planner may be required where the proposal triggers planning assessment or needs interpretation beyond structural 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!

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

FAQ & ENGINEERING GUIDE

About Toowoomba Engineering

No. The engineer prepares structural design, assessment and supporting documentation. A licensed building certifier assesses the building application and determines approval and inspection requirements.

Professional engineering services carried out in or for Queensland generally need to be provided by, or under the appropriate supervision of, a Registered Professional Engineer of Queensland. The required engineering discipline and certification depend on the work.

It depends on the structure, available records and site conditions. New buildings, substantial retaining walls, filled sites, unusual foundations and sloping properties often require appropriate ground information. Ostanes does not provide soil testing but can use relevant geotechnical information in the structural design.

No. A structural engineer focuses on load-bearing behaviour and the structural concerns defined in the scope. Ostanes does not provide pest or termite services.
