Warehouses and distribution. Storage cubic without moving the building.
3PLs, distribution centres, and inventory-heavy operations across Ontario. The typical scope in this vertical is storage mezzanines — recovering 4,000 to 25,000 sqft of usable deck above the floor, sized to actual pallet load, with stair access that doesn't trip an occupant-load review.
Cubic recovery, not square-footage shuffling.
The pattern is consistent in this vertical: clear height is unused, floor space is full, and the operation needs another 5,000 – 15,000 sqft of usable deck without expanding the building. The structural mezzanine is the standard answer; what differs from project to project is load class, deck choice, and how the stair access integrates with rack lines and forklift paths.
Common scopes
- Storage mezzanines — single or multi-tier; sized to pallet weight at full density, not the catalogue average.
- Multi-tier mezzanines — for buildings with 24 ft+ clear height, two or three stacked decks recover the most cubic.
- Work platforms — for shipping / receiving stations and supervisor decks where people occupy the deck.
- Mezzanine access stairs — sized to occupant load; second-stair threshold checked at site measure.
- Egress staircases — when the deck triggers a fresh OBC §3.4 review.
What changes vs. retail / office buildings
- Slab capacity — purpose-built warehouse slabs handle the column loads. Converted retail or office buildings often don't, and that's a site-measure verification before we draw anything.
- Forklift access patterns — turning radius around stair towers, pallet-drop locations, and rack-aisle alignment all sit on the drawing before fabrication starts.
- 24/7 operations — install windows are constrained to specific shutdown blocks. We coordinate to those blocks, not around them.
- Rack-line interaction — mezzanines that share floor space with selective racking need the rack column line and the mezz column line on the same drawing; surprises here are the costliest install delays.
