Supporting line: Commercial plumbing fitouts across Brisbane, plumbed to work on day one and still be serviceable in year ten
A commercial plumbing fit out covers the water, drainage and gas work inside a tenancy, from rough-in through to fit-off and compliance sign-off. The difference from general plumbing is load and consequence. A house has one shower running at a time. An office floor, a gym or a busy cafe draws from several fixtures at once, and the pipework has to be sized for that peak before the walls close up.
Undersizing is the most common regret we see, and lining hides it.
Commercial fit out contractors size for simultaneous demand and plan isolation so one tenancy can be worked on without shutting the building down.
We take the hydraulic scope from rough-in to fit-off: cold and hot water reticulation, sanitary drainage, floor wastes, tempering valves, backflow prevention and gas rough-in and certification. Commercial kitchen fit out work adds trade waste, grease arrestor connections and stainless fixtures that live under real heat and hours.
Set-out is where most of the value sits. We coordinate fixture positions and heights against joinery and shopfitter drawings before rough-in starts. We work alongside the head contractor and the site supervisor for the whole program. Architects’ drawings get checked as they change, not only at inspection points. Where a drawing conflicts with the build, we raise it at set-out stage, while the fix is still a drawing revision.
One point of contact from tender to handover, including as-builts and certificates for your asset register.
We check the hydraulic drawings against the real build before pricing, then set out plainly what we supply and what stays with the client.
Fixture positions and heights are marked against joinery drawings, carpenters nog out for grab rails and wall-hung pans, and every wall is photographed before sheeting.
Pipework sized for peak demand goes in, with isolation at tenancy and room level so future work never shuts down the whole site.
Fixtures go on, systems are tested and certified, and the compliance paperwork lands with you before the doors open.
We do. Trade waste and backflow approvals go through Queensland Urban Utilities, and plumbing work is certified against AS 3500 and the Queensland Plumbing and Wastewater Code. Get your compliance signed off in stages rather than as one certificate at handover. A single sign-off at the end gives you nothing to act on if something failed early.
The hydraulic program is set by the build sequence. Rough-in has to land before wall lining and screeds, so a delayed frame or a late slab penetration moves everything behind it. On a small cafe or retail fitout the plumbing may be a few weeks across two visits. Warehouse and medical fitouts in Brisbane run in stages over months.
Trade waste and grease management drive most of it. A restaurant fitout in Brisbane needing a new arrestor and floor waste upgrades sits well above one connecting to existing infrastructure. Fixture count and how far services travel from the riser move it too. We price from drawings and a site inspection, never from a phone description.
Night and weekend work is normal on occupied sites, because a live tenancy can't lose water on a trading day. We stage isolation and cap off so the floors above and the businesses beside you keep running while your section is out. Access and induction requirements get agreed with the site supervisor first.
Refits in existing buildings trigger current standards. A like-for-like replacement can still require a floor waste where none existed,
Once lining goes on, pipe sizing and isolation are locked in for the life of the tenancy. Send your drawings through and we’ll flag what needs sizing up before it disappears behind a wall. Call us today.
