A shop sized to the work, not a catalog width.
Engineered MegaDome workshop and maintenance buildings for fleets, dealers, mines and contractors — bay layout, clear height and crane support planned around how your shop actually runs, built by one Ontario team.

Clear height, clear span, no columns in the way.
A workshop building has to clear the tallest unit that rolls through the door, give a technician room to work around it, and — if the job calls for it — carry a crane or hoist overhead. The clear-span frame means bay width isn't broken up by columns, so the layout is set by your equipment and workflow rather than a structural grid.
- →Eave height and arch rise set to your tallest lift point plus clearance
- →Crane or hoist support engineered from the frame or on independent runway columns
- →Drive-through or dead-end bays, or a mix, based on what actually needs to turn around
- →Membrane warranty terms confirmed in the issued documents
Bay Layout Sized to the Work
Bay count and width driven by how many units need service at once and how they queue — not a stock footprint.
Clear-Span, Crane-Ready
No internal columns to work around, with crane or hoist support engineered from the frame or on independent runway columns.
Built for Year-Round Shops
Insulation, radiant heat and unit heater options sized to keep the bay usable through an Ontario winter.
Ventilation Planned for the Work Done Inside
General air changes plus dedicated exhaust and welding fume extraction where the shop's work calls for it.
How many bays, and what kind, before how big.
Bay count and configuration come from how the shop actually operates, not a target square footage. These are the inputs we work through before a layout is drawn:
- →Number of bays and whether units are serviced simultaneously or queued
- →Drive-through versus dead-end bays, based on unit length and turnaround time
- →Tallest equipment, lift type and maximum lift height
- →Crane or hoist capacity, hook height and duty cycle, if required
- →Dedicated bays for welding, wash-down, parts or tire work
- →Office, mezzanine or parts storage carved out of the shop footprint
Send those details and we'll come back with a bay layout, a foundation approach and a preliminary budget range. Preliminary figures are for budgeting only — final pricing follows engineering, site conditions and the configuration you select.

Drive-through bays save time on long trucks, trailers and equipment because nothing backs out through the same door it entered — useful where turnaround speed matters more than end-wall cost. Dead-end bays cost less per bay and let you close off the back for a parts room, mezzanine or storage. Most multi-bay shops mix both, matched to what actually needs to pass straight through.
A shop that's actually usable in February.
A workshop that only works in summer isn't a workshop — it's a garage with a season. Radiant tube heat is common in fabric shops because it warms the floor and equipment directly, so heat recovers quickly after a bay door cycles open. Unit heaters suit smaller or less-frequently-opened spaces. Ventilation is sized separately from heating: general air changes for occupied space, plus dedicated exhaust and welding fume extraction where that work happens in the shop. Insulation levels are matched to how the building is heated and how the doors get used through the day.
- →Radiant tube or unit heater systems specified to bay use
- →General ventilation plus dedicated exhaust/welding extraction where needed
- →Insulation package matched to door-cycle frequency and heating method
- →Translucent membrane brings in daylight, reducing daytime lighting load
Crane and hoist support
Lighter-duty hoists and jib cranes can often be engineered directly into the fabric frame. Heavier-capacity bridge cranes are typically supported on independent runway columns set inside the clear span, isolated from the building envelope so crane loads don't transfer into the roof structure. Tell us the crane capacity, span, hook height and duty cycle, and we'll engineer the support method to match.
What goes in before the walls close up.
Lighting & power distribution
High-bay LED lighting sized to task areas, plus panel and circuit layout for tool drops, welders and shop equipment planned with your electrical trade.
Compressed air & fluid runs
Air line and fluid-service routing planned into the building layout before slab and wall are closed in, not retrofitted after.
Slab, pit & drainage intent
Slab thickness set to the loads it carries, with inspection pits, trench drains or fluid containment designed into the concrete package where the service model calls for them.
Insulation package
Wall and roof insulation levels matched to how the shop is actually heated and how often doors cycle through the day.
If a pit, trench drain or specific fluid-containment detail is part of your service model, it has to be designed into the slab before concrete is poured. Tell us early and it's built into the foundation package rather than retrofitted later.
Different fleets, different shop needs.
Mining and aggregate operators
Heavy equipment maintenance shops built to clear haul trucks and loaders, with crane support for engine and component work.
Trucking fleets and equipment dealers
Multi-bay service shops sized to fleet throughput, with drive-through bays for trailers and long combinations.
Agriculture operators
Equipment repair and winter storage shops sized to combines, sprayers and implements, insulated for cold-weather work.
Construction contractors and municipal yards
Fleet maintenance and equipment shops attached to a yard, sized around what rolls through on a given contract or service route.
Send us these and we'll come back with numbers.
