Engineering & compliance

A shelter is only as good as the certification behind it.

Wind region governs the structural design of every structure you erect on site. Our most common dome sizes are engineered to carry frame certifications for Wind Region C and D, the cyclonic and severe-cyclonic classifications that cover most of WA's north. Tell us where it's going and we'll confirm the wind region it sits in.

AS/NZS 1170.2 Regional wind classification
A
Non-cyclonic. Perth, the Wheatbelt, the Goldfields.
B
Intermediate. The transition band inland of the coast.
C
Cyclonic. The Gascoyne, the Pilbara and the Kimberley.
D
Severe cyclonic. The exposed north-west coastal strip.

Certification to a region is the baseline: a generic certificate for the dome design, not an assessment of your site. Where a site sits in exposed terrain, on unusual ground, or carries loads the standard design doesn't anticipate, we can arrange site-specific engineering, including weight ballast calculations, so the installation is signed off for the ground it's actually standing on. For Region C and D sites we strongly recommend it. Site-specific engineering is an optional add-on, quoted separately from the standard package.

Standard

Certification you can hand to your client

Our most common dome sizes come with a generic certificate for their wind region rating. It doesn't assess your site, so for Region C and D sites we strongly recommend site-specific engineering.

Optional add-on

Site-specific engineering

Where your site needs it, we can arrange engineering worked to your exact coordinates, terrain and loading, including weight ballast calculations. Quoted as an add-on, not included as standard.

Dome shelters

Covered workspace, spanned between two rows of containers.

A galvanised steel frame carrying a tensioned dome tarp bridges the gap between two shipping container walls, turning the empty space between the containers into a sheltered workshop, laydown area or storage bay. No shed slab, no long build program, and it can be taken down and moved when the work moves.

What a turnkey package covers

  • The domeStrong & durable galvanised steel framing and an industrial-grade dome tarp. Our most common sizes are certified with the tarp fitted up to Wind Region B. In Regions C and D the frame is certified and the tarp must come off when a cyclone alert is issued.
  • The containersSupplied as part of the package, or we design around the units already on your site.
  • TransportDelivery to site is part of the package, coordinated so it lands when the crew does.
  • InstallationContainers set, dome erected and everything secured in a single mobilisation.
  • CertificationThe generic wind region certificate where your dome model carries one, handed over once the job is paid in full, ready for your site records.
Dome widths Width is the clear span between the two container rows
  • 6m
  • 8m
  • 10m
  • 12m
  • 14m
  • 16m
  • Custom sizes

Every width is available in a dome built to suit either 20ft or 40ft shipping containers, so the length of the covered area follows the containers you are spanning. Anything outside the standard range is built to order.

Extras we fit at install

Specified with the dome and done in the same visit, rather than booked as a second mobilisation.

Engineering

Site-specific certification

Certification worked to your exact coordinates, terrain and loading. Strongly recommended for Region C and D sites.

Engineering

Ballast calculations

Weight and anchoring worked out properly for the ground you're on.

Groundworks

Precast concrete footings

Supplied to lift the containers clear of the ground and sit them level. For ground clearance and, to a lesser extent, levelling.

Electrical

Workshop lighting

Lighting runs installed through the dome so the bay is usable from day one.

Fabrication

Removable end walls

Tarp end walls on custom-fabricated pulley systems, opened by one person.

Branding

Custom vinyl signage

Cut vinyl logos applied to new containers and container builds supplied by us.

Logistics

Relocation

Dismantle, transport and re-install when the work moves to the next site.

Service

Maintenance

Dome tarp inspection, repair and replacement over the life of the shelter.

Modified shipping containers

Site buildings that arrive finished and land on the pad.

We modify shipping containers into the buildings a mine or exploration site actually runs on, built by our fabrication partner, delivered complete, and available to buy or lease. On the Cue job we upgraded the containers to high cube and reconfigured the ablutions, both as variations to the same job.

20ft / 40ft · GP or HC

Site offices

Insulated and lined, windows and secure door, power and data rough-in, air conditioning, and floor plans split to the number of rooms you need.

20ft / 40ft · GP or HC

Crib rooms

Kitchen fit-out, bench and sink, seating for the crew size, insulation and air conditioning sized for the conditions you're working in.

ABK · self-contained

Ablution blocks

Toilets, showers and hot water in a sealed, self-contained unit. Toilet-to-shower split configured to the crew, not fixed to a catalogue layout.

Remote camps

Accommodation units

Sleeping quarters built for exploration and remote-site rosters, insulated and air conditioned for sustained use away from a camp.

Secure storage

Workshops & stores

Shelving, benches, lighting and security hardware fitted out so consumables and tooling have a locked, dust-sealed home on site.

Built to brief

Custom builds

Get in touch to discuss what you need and we'll spec, price and build it.

Modification, not selection

If the standard unit isn't right, we change the unit.

On a recent exploration job the client needed more headroom than the standard shell gave them and a different wet-area split. We upgraded the container from general purpose to high cube and reconfigured the ablution block from four toilets to three toilets and a shower. Both changes were priced into the original quote rather than raised as a variation after delivery.

Commercial terms

Three ways to hold the same asset.

Domes and modified containers are available on all three terms. Tell us the scope once and we'll price it every way, so the decision is a commercial one rather than a second round of quoting.

Purchase

Outright

Supply, transport and install, and the asset is yours.

  • Best where the site or the workshop is a long-term fixture
  • Certification documentation transfers with the asset
  • Relocation and maintenance available later as separate scopes

Lease

Fixed term

Hire for a defined term, sized to the length of the project.

  • Suits exploration programmes and contract-length work
  • We deliver, install, and remove at the end of the term
  • Term extensions handled without re-mobilising

Rent-to-own

Hire to purchase

Hire payments contribute toward owning the unit outright.

  • For work that may well outlast the original programme
  • Keeps the up-front number down without closing off ownership
  • Terms set at quote stage, in writing

Commercial terms only. Nothing here is financial or tax advice. Take your own advice on how a purchase, lease or rent-to-own arrangement sits with your accounting treatment.

How it works

From first call to handover.

Six steps, in order. Most of the work sits in steps two and three. Get the scope and the site right and the rest is scheduling.

  1. 01

    Request a quote

    Call us or send an enquiry. Location, rough timeframe and what you need the shelter or building for is enough to get started. You don't need a specification written yet.

    Need: site location · timeframe · intended use

  2. 02

    Scope of works

    We work through it with you: clear span, length and height for the dome; container type, count and fit-out; what's already on site and what we're supplying; and what has to happen underneath, such as hardstand, footings and power.

    Helps: site photos · a pin on a map · any existing container details

  3. 03

    Site and wind region check

    We confirm the wind region for your coordinates and whether a generic certificate applies. For Region C and D sites we strongly recommend site-specific engineering and ballast calculations, quoted as an add-on. This is settled before you get a price, not after.

    Output: region confirmed · engineering path decided

  4. 04

    Proposal

    One quote for supply, transport and installation, with the price locked in once paid in full. It's priced for purchase, lease and rent-to-own so you can compare, with the estimated lead time and inclusions confirmed in writing.

    Output: written quote · three commercial options · estimated lead time

  5. 05

    Delivery and installation

    Containers placed on precast footings, dome erected and everything secured. Every extra you specified, such as lighting, signage and end wall systems, is finished in the same mobilisation.

    On site: install crew · all extras in one visit

  6. 06

    Handover

    You get the generic wind region certificate where your dome model carries one, plus any site-specific engineering you added, a walk-through of the installation, and a direct contact for maintenance, relocation or adding to it later.

    Output: generic wind region certificate · handover walk-through · ongoing contact

Scope
Supply and install

Covered yard space, manufacturing client

This client needed a covered working and storage space at their facility. We supplied both the containers and the dome, set the containers to the span required, and installed the shelter over them. Completed in the same fortnight as the Cue job.

Scope of works

  • 01Supply of shipping containers
  • 02Supply of dome shelter
  • 03Positioning of containers to the required span
  • 04Installation of the dome shelter

Why a dome

A metropolitan yard with a hardstand already in place. The dome turned unused hardstand into covered, usable floor area without a shed build, and the containers carrying it double as secure storage on both sides of the span.

Common questions

Before you call.

Do I need a concrete slab?
No. Container dome shelters are designed to sit on the containers themselves, so a prepared, level hardstand is usually all that's required. We don't pour slabs or footings. We do supply precast concrete footings, which lift the containers clear of the ground and can assist in sitting them level.
Can the shelter be moved later?
Yes, and that's much of the point. The dome dismantles, travels with the containers, and re-installs at the next site. Relocation is quoted as its own scope, and the certification is reviewed against the new site's wind region before it goes back up.
What certification do we receive?
Our most common dome sizes come with a generic wind region certificate: tarp fitted up to Region B, frame only in Regions C and D. Your invoice states whether your dome model carries one. Site-specific engineering is an optional add-on.
Do you supply the containers, or can we use ours?
Either. Most turnkey packages include the containers so the whole scope sits with us, but we're equally happy to design the dome around units already on your site. We'll need the type, condition and dimensions to check they suit.
How far out do you deliver?
Across Western Australia, including remote mining and exploration sites. Interstate delivery is available on request. Tell us the location and we'll price the transport leg with the rest of the job.
What size domes do you offer?
Widths of 6m, 8m, 10m, 12m, 14m and 16m, with custom sizes built to order. The width is the clear span between the two container rows, and each width comes in a version to suit either 20ft or 40ft containers, so the length of the covered area follows the containers you are spanning.
What's the lead time?
Typically 2 to 4 weeks, depending on the size of the dome, the container fit-out and whether the site needs site-specific engineering. We confirm an estimated lead time in writing with the quote.
