Proof · Case Study

Liebherr Australia — National Crane Depot, QLD

Liebherr needed a single facility to base their tower-crane division — office, parts and amenities — on a yard alongside live operations. We delivered seven modules joined into a 21×12m building, configured for scale at the QLD site.

FAQs

What everyone asks.

Quick answers on lead time, transport, installation, sizes and customisation. Need specifics? Give us a call

What's the typical lead time? +
Standard sizes (6×3, 9×3, 12×3) — 4 to 8 weeks from order, depending on production slot. Custom and multi-module builds — 8 to 14 weeks. We confirm your slot in the quote.
Do you deliver Australia-wide? +
Yes. We've delivered 889+ buildings across every state, with projects from the Pilbara to the Hunter Valley to inner Melbourne. Transport is itemised in your quote.
Can I customise the layout? +
Yes. Most orders include some customisation — door positions, internal walls, electrical, A/C, decking. We'll work to your floor plan or design one with you.
What sizes do you build? +
Our standard office range is eight sizes: 3x3, 4.8x3, 6x3, 9x3, 12x3, 12x6, 12x9, 12x12. We also build to custom dimensions and join modules into multi-room complexes — see the Liebherr depot above for a 7-module example.
How does transport work? +
We arrange road transport from our Australian facility to your site. Standard sizes ship as a single load; multi-module builds ship in stages and we coordinate with your site team for crane and placement.
What about installation? +
Turnkey buildings supply with installation: levelling, stair / decking install, services connection. The level of installation depends on the project — we'll scope it in the quote.
