Form 15 (RPEQ compliance certificate, Qld)
Form 15 is the Queensland Compliance Certificate for Building Design or Specification, signed and stamped by an RPEQ certifying an engineered design complies.
Ask Chalkline about this →Form 15 is the Queensland Compliance Certificate for Building Design or Specification: a statutory building form on which a competent person certifies that a building design or specification complies with the relevant building standards. For engineering designs it is signed and stamped by an RPEQ (Registered Professional Engineer of Queensland) who prepared or reviewed the design (verified 2026-05-24, Business Queensland).
What it does:
- The author of a design certifies on a Form 15 that their design or specification complies with the Building Code and relevant standards.
- The building certifier relies on Form 15 certificates to be satisfied that specialist parts of the design (structural, fire, hydraulic) comply, without re-checking the engineering.
Who signs it: for engineering aspects, an RPEQ stamps and signs the design documentation and completes the Form 15, and carries the professional and legal responsibility for that certification (verified 2026-05-24, BPEQ). Other competent persons may sign a Form 15 for non-engineering design aspects within their competence.
Form 15 vs Form 16:
- Form 15 certifies the design complies (design stage).
- Form 16 certifies the work was inspected or built to comply (construction stage).
For a Qld builder: collect the Form 15s for the engineered elements of the job (footings and slab, steel, trusses, fire systems) from the relevant RPEQ, because the certifier will want them. A missing or wrong Form 15 holds up certification, so make sure the form matches the design actually built and chase a revised Form 15 if the design changed.
Also known as: Form 15 compliance certificate, design compliance certificate (Qld).
