Fire protection design, coordinated and permit-ready

Life-safety systems are a design, not a submittal errand

Fire protection fails projects quietly: a sprinkler scope discovered late, a water supply that won't support the hydraulic calculation, an alarm design that fights the electrical set. Torch designs fire protection with the building instead of after it — hazard classification, water supply, and system layout resolved alongside the architectural, structural, and electrical work, so the life-safety package supports the permit instead of threatening it.

Scope and deliverables

· Fire sprinkler design — layout, hazard classification, and hydraulic calculations against the available water supply
· Fire alarm design — detection, notification, and the system documentation reviewers require
· Suppression design for special hazards, coordinated with the processes they protect
· Water-supply analysis — flow-test interpretation and the case for pumps or tanks where the supply falls short
· Fire protection sets delivered with the MEP package or standalone, coordinated against the building's structure and ceilings

Deliverables are permit-ready drawings and calculations, sealed through Apex Grid Engineering's licensed Professional Engineers where a seal is required, with plan-check responses handled by the design team.

Where the work concentrates

Change-of-use and tenant-improvement projects that trigger sprinkler requirements. Warehouses and storage occupancies, where classification drives everything. Multifamily, hospitality, and assembly work where life-safety systems are central to the permit. State coverage starts with fire protection engineering in Arizona.

How the design gets coordinated

Fire protection coordinates or it fails: sprinklers thread the same ceiling space as ducts, lights, and structure; the alarm ties into the electrical design; the hydraulic calculation depends on the civil team's water supply at the street. Torch designs fire protection in the same office as those disciplines, so head placement respects the ceiling plan, device locations respect the electrical layout, and the water-supply analysis starts from the actual utility data. Life-safety systems carry enough review scrutiny on their own — the design should never add coordination comments to code comments.

Common questions

Do I need fire sprinklers in my building?

It depends on occupancy, size, construction type, and the local amendments — which is why the answer is a code analysis, not a guess. Our answers library works through when sprinklers are required, and ADU projects have their own common case in our ADU sprinkler answer.

What is a hydraulic calculation?

The proof that the water supply — at its tested pressure and flow — can deliver what the sprinkler design demands at the most remote head. It is the calculation fire protection reviews are built around, and the reason water supply gets analyzed before layout, not after.

Who stamps the fire protection drawings?

All PE stamping is backed by Apex Grid Engineering, whose licensed Professional Engineers seal the work in the project state. Torch does not present itself as the licensed entity.
