Wind-load engineering done properly.

Cardinia Shire is in AS 1170.2 wind Region A2, with most suburban blocks falling in terrain category 2.5. We calculate the ultimate design wind speed at ~41 m/s and engineer post size, footing depth and roof fastener spacing to that load. The engineer’s certificate is issued at quote stage and travels with the building permit application. Cardinia Shire building surveyors check it at frame stage — if there’s no engineer’s certificate, the inspection fails.

Colorbond colours we keep in stock.

The five most common roof colours across Cardinia growth-corridor estates — Monument, Basalt, Woodland Grey, Wallaby, Manor Red — we keep in stock and can usually build within standard lead time. Less common colours (Surfmist, Cottage Green, Headland, Heritage Red, Indian Red, Dune) typically add 1–2 weeks lead time but no price premium.

Lead time.

From site visit to finished carport, typical timelines:

• Site visit + fixed quote: 7 days
• Contract signed, deposit, permit lodged: 1 week
• Building permit issued: 2–4 weeks (private surveyor)
• Planning permit (if needed): add 4–10 weeks
• Steel ordered, crew booked: 2–3 weeks
• Build duration: 3–7 working days incl. footing cure
• Final inspection + handover: 1 week

So a straightforward Cardinia Lakes single carport — site visit to handover — is typically about 5–6 weeks. Heritage Overlay or planning-permit jobs add 4–10 weeks at the council end.
