Most initial responses are within 24 hours. Timeframes for delivery of outputs (like compliance documentation or SEDs) depend on the complexity of the request, but typically within 3–5 working days from when all required documents are received and the service is requested.

Many of our services are provided at no cost as part of our partnership with our supply partners. If a request requires an engineered slab design, we’ll let you know upfront and get your approval before proceeding. When your project needs an SED (Specific Engineering Design) for a SuperSlab foundation, here’s what you can generally expect: Standard residential SED designs (single storey, typical builds) Usually completed within 3–5 working days Indicative fees start around $750 + GST, depending on floor area and specifics. More complex or bespoke designs (e.g. two storey homes, or additional geotechnical coordination) Typically completed within 4–6 working days Indicative fees from $1050 + GST. Express turnaround options Available by arrangement, with faster delivery times and adjusted fees. Pricing is scaled by floor area For example, simpler SED jobs often start around $3.75 + GST per m², with more involved projects at higher rates. Site inspections & PS4 certification In-person inspections typically range from $700–$950 + GST, depending on location. Virtual inspection options are also available, generally starting from $550 + GST. We’ll always provide a tailored quote for your project rather than publishing a fixed price list because exact fees vary depending on project size, site conditions, turnaround times, and complexity, ensuring you know your precise costs before proceeding.
