Fire System Engineering for New Builds and Retrofits
Total Group supports fire system engineering for new construction, system upgrades and retrofit projects. The work can cover fire protection system design coordination, system layout, hydraulic calculations and equipment selection, with the project scope shaped around the facility, existing conditions and available project information.
Fire system engineering scope
- Fire protection system design and layout support.
- Hydraulic calculations for water-based fire protection designs where included in the agreed scope.
- Equipment selection support for the proposed system.
- Coordination with architects, contractors and facility managers.
- Support for new installations, upgrades and retrofits.
Engineering support is different from inspection, testing, maintenance and installation. A project may need one or several of these activities. Confirm whether the request concerns a new system, a change to an existing system, project design documents, construction coordination or support after installation.
What the design work is intended to address
A fire protection design connects the building, its use and its fire protection equipment. Layout work considers where system components are placed and how they fit the building and other services. Hydraulic calculations assess the water-flow requirements for a water-based design. Equipment selection considers the proposed application and the information available for the project.
These tasks do not replace the project’s approval process. The applicable building and fire code, referenced standards, permit conditions and authority having jurisdiction (AHJ) requirements depend on the location and project. Canadian standards provide technical purposes for particular activities, but a standard’s name alone does not establish the edition or legal requirement that applies to a facility.
Code, standards and approval context
Alberta provides a useful example of why the project location matters. The Alberta government lists the National Fire Code – 2023 Alberta Edition, second printing, as the fire code in force on its current fire codes and standards page. Alberta also explains that Fire STANDATA may provide province-wide variances, interpretations or general advice, and that the code year affects how those documents are used. Requirements in another province or territory should be checked separately.
For fire alarm work, Alberta’s official existing-system interpretation distinguishes installation, inspection and testing, and verification. It identifies CAN/ULC-S524 for installation, CAN/ULC-S536 for inspection and testing, and CAN/ULC-S537 for verification. The applicable code and referenced standard edition must be confirmed for the project. Similar care is needed when a fire system design interfaces with fire alarm functions, building services or other life-safety systems.
Where legislation, the AHJ, the permit or the project requires professional engineering work, a qualified professional engineer or other permitted design authority must be involved. Alberta’s engineering regulator, APEGA, publishes requirements for authenticating professional work products. Total Group can discuss the project support available, but this page does not represent that Total Group provides a P.Eng., professional engineer seal, stamp or design authority for every project.
When to arrange engineering support
Contact the team early when a new building is being planned, an occupancy or process is changing, an existing system is being upgraded, or a retrofit must fit around existing services. Engineering input may also help when a contractor needs design information, when an owner is comparing equipment options, or when existing drawings and field conditions do not match.
Design work should be coordinated with the owner, architect, contractor, facility manager and AHJ as applicable. The owner remains responsible for providing accurate project information, identifying the intended use and occupancy, disclosing known hazards or changes, and confirming the approvals and professional sign-off required for the jurisdiction. A design document or calculation by itself does not prove that the completed system is adequate, approved or ready for service.
What to prepare for an inquiry
- Project location: Province or territory, municipality and site address.
- Project stage: New construction, upgrade, retrofit, tenant improvement or existing-system review.
- Facility information: Building use, occupancy, areas affected and known changes to processes, storage or equipment.
- Available documents: Architectural or mechanical drawings, existing fire protection drawings, specifications, equipment schedules, prior calculations and approval comments.
- Existing conditions: System type, water-supply information, known deficiencies, prior modifications and interfaces with fire alarm or other building systems.
- Project contacts: Owner or facility contact, architect, contractor, consultant and AHJ contact where available.
Share the project documents and the decision you need to make. Total Group can review the information, discuss the requested engineering scope and identify what additional professional, code or AHJ input may be needed.
Discuss your fire system engineering requirements
Send Total Group your project location, system type, drawings and requested deliverables. The team can confirm the available project support and the information needed to define the work. For related fire protection services, visit the Fire Services hub.
