Form 12 & Form 15 Certification FAQs for Yeronga Projects
Q1: What’s the difference between Form 12 and Form 15?
Form 15 certifies a design (like a slab or patio), while Form 12 confirms the completed work matches the certified design. Both are often needed for approval.
Q2: Do I need a Form 15 if my builder designed the carport?
Yes—if the structure is not pre-engineered, it must be certified by an RPEQ engineer before it can be approved by a certifier.
Q3: How fast can you issue a Form 15 in Yeronga?
We can usually inspect and certify within 2–3 business days, depending on the job. Let us know your timeline—we’ll do our best to meet it.
Q4: Can you inspect completed works and issue Form 12?
Yes. We often inspect completed retaining walls, decks or extensions to confirm they were built as per the approved design.
Q5: Do you service Yeronga suburbs like Woodridge, Waterford or Beenleigh?
Absolutely—we service the entire Yeronga region and surrounding areas.
