In-House Engineering for Your Jurisdiction

The engineer who draws your unit works in the same building as the line that builds it. That is why the erection drawings describe the steel that is actually in the container.

Catalogue engineering fails at the border. A generic load case and a generic drawing do not satisfy a building authority that wants to see calculations for the wind speed, the seismic zone and the snow load at the actual site.

Our engineers prepare structural drawings, load calculations and stamped reports for your jurisdiction, engineered to AS/NZS, EN (CE) and the loads you specify — with material certificates and load-test reports supplied per order.

Because engineering and fabrication share a site, the erection drawings and the steel agree. Bolt holes are drilled to the drawing, members are marked to the drawing, and the crew on site builds from the same document.

Process

Every Stage End to End

Eight stages from first enquiry to a building standing on your site.

01 Site and code data

Wind speed, seismic zone, snow load, exposure category and the code your authority works to. Where you do not have them, we will say so rather than assume.

02 Concept and layout

The building or camp is laid out on the module grid, with circulation, stacking and extension considered from the start.

03 Structural design

Frames, connections and — for multi-storey work — the load path down to the foundation are designed as one system.

04 Load calculations

Calculations prepared against the specified loads, including the stacking case for two and three-storey camps.

05 Stamped reports

Reports prepared for your jurisdiction, so the package is something a building authority can review.

06 Fabrication drawings

Cutting and drilling data issued straight to the CNC lines, so the steel matches the drawing by construction, not by inspection.

07 Erection documentation

Erection drawings, member marking and a bolt and panel schedule produced for the crew who will actually build it.

08 Support through assembly

Engineers stay reachable while the building goes up, so a question is answered rather than guessed.

Why it matters

What This Changes for the Buyer

Approvable packages

Drawings and calculations prepared for your jurisdiction rather than generic catalogue sheets.

Drawings that match the steel

Engineering and fabrication in one building removes the gap where errors normally live.

Your own drawings accepted

Send what your architect or engineer has produced and we return a prefab version of it.

Documented materials

Material certificates and load-test reports supplied per order.

Buyer questions

In-House Engineering FAQ

What buyers want to know about how we work.

Which codes do you engineer to?

Structures are engineered to AS/NZS, EN (CE) and your specified wind and seismic loads, with material certificates and load-test reports supplied per order.

Can you work from our architect's drawings?

Yes. Send the architectural or structural drawings you have and our engineers return a prefab version with the connections, load calculations and packing detailed.

Do you provide stamped calculations?

Stamped reports are prepared for your jurisdiction as part of the engineering package.

What site data do you need to start?

Wind speed, seismic zone, snow load where relevant, exposure and the code your authority works to, plus the site dimensions.

What if we do not have the load data?

Tell us and we will identify what is missing rather than assuming a value. Anything not confirmed is flagged on the drawing.
