Does a factory certificate replace a Victorian building permit?
No. Clarify what the certificate covers: a product, a quality system or particular work. The project still needs its applicable approvals and site-specific design. Ask the relevant building surveyor what evidence must accompany the permit application and how offsite stages will be assessed. Do this before manufacture makes the work difficult to inspect or expensive to change.

Have the relevant building surveyor establish the edition and any transitional provisions for the project. BPC identifies Victoria’s NCC 2025 adoption from 1 May 2026 and describes a discretion for some substantially progressed earlier designs. A supplier’s older standard drawing or handbook does not establish that discretion. Record the accepted basis before comparing certificates, engineering and production drawings.

Check the product identity, current status, referenced technical documents and every condition or limitation against the proposed use. CodeMark supports the requirements specified by the certificate; it does not certify unrelated site works or any configuration using a similar product name. Ask the surveyor to confirm acceptance for this project, particularly if the certificate refers to an earlier NCC edition.

Verify the exact model and licence in the official product database and obtain the relevant scope information. WaterMark requirements apply to products within the scheme, not simply to a supplier as a whole. Have the licensed plumbing practitioner check the specified products before ordering and installation. Keep the model record with the procurement schedule so a visually similar substitute is not accepted without review.

Its origin alone does not answer the question. The responsible assessor needs evidence that is appropriate to the product, the intended use and the applicable requirements, with the full report and limitations available. Map the report to the specified assembly and installation rather than relying on a cover-page badge. Resolve any additional assessment before ordering material that the project may be unable to use.

Agree the inspection and evidence plan before production, including who must review each stage and what may not be concealed until that review occurs. Photographs should identify the module, location, date and drawing revision, but they are only part of the agreed record. Confirm the surveyor’s requirements directly; a supplier’s photo folder should not be assumed to replace an inspection that is required.

Name the responsible designer and receiving contractor in an interface schedule. Record the survey datum, dimensions, tolerances, loads, fixing points and service locations that must agree before manufacture and before delivery. Require discrepancies to return to the responsible engineer or designer. The owner needs evidence that these interfaces were coordinated; this checklist is not a substitute for their structural or installation design.
Link to this answer · 07Can a factory replace an unavailable product with one described as equivalent?
Require a documented substitution review before the change is made. Compare the performance, dimensions, installation requirements and supporting evidence with the approved design, including effects on connected systems. The responsible designer or assessor must determine what approval or updated documents are needed. A matching appearance or lower cost does not settle fire, moisture, structural, energy or warranty compatibility.

Identify and photograph the damage against the module record, notify the responsible parties and keep it out of the acceptance sign-off until assessed. Obtain the appropriate technical assessment and a documented repair scope where needed, then retain the inspection and repair evidence. Allocate responsibility under the contract and insurance arrangements. Cosmetic patching alone should not close a question about hidden or structural damage.
Link to this answer · 09How can the owner verify that the delivered building matches the approved prefab specification?
Use a reconciled schedule of module identities, installed product models, accepted changes, site inspections and completion documents. Include the final drawings and the evidence for site-made connections and weatherproofing interfaces. Mark outstanding items and their owners. This links the factory package to the installed building, allowing the owner and future maintenance team to identify what was supplied and which documents apply.
