Skeleton Steel Frame – Building Permit & Engineering Certification
If your project requires a Building Permit, we can assist you in obtaining the necessary engineering certification and footing plans. To provide you with a site-specific Engineering Certificate and Footing Plan, there is a fee of $550. Below are the steps required to proceed:
- Purchase the Frame – Complete the purchase and payment for your steel frame.
- Provide Property Details – Share the property address and specify where on the site the frame/s will be located.
- Architectural Drawings or Concept Plan – Provide drawings with location of windows, doors & internal walls.
- Soil Report (if required) – For an accurate footing plan, a soil report is necessary.
- If you already have a soil report, please send it to us, and we will forward it to our engineer.
- If you need a soil report, we can arrange for our geotechnical technician to visit your site (Victoria only). Additional fees will apply based on your location. For projects outside Victoria, you will need to arrange the soil report independently.
- Engineering Calculations – We will engage our engineer to perform the required calculations.
- Processing Time – Please allow 1-2 weeks for the engineer to complete the documentation.
- Documentation Issued – Once finalized, we will provide you with the following:
- Structural Documentation
- Structural Drawings
- Computations & Certification
Once you receive the documentation from us, the next step is to engage an architect (if you haven’t already) and a building surveyor to proceed with your project.
For any questions or to begin the process, feel free to contact us!
