Our experienced engineers deliver practical, code-compliant solutions tailored to your facility, ensuring safety, quality, and reliable project execution.
Using BIM, Autodesk Revit, AutoCAD Plant 3D, HYDRAtec, AutoSPRINK, and AFT Fathom, we create coordinated 3D designs, accurate hydraulic models, and efficient system layouts.
Working closely with clients, consultants, and contractors, we provide transparent communication, coordinated engineering, and on-time project delivery.
Proper fire alarm and suppression system design ensures fast fire detection, effective suppression, and compliance with safety standards—protecting lives, assets, and property.
We strictly follow NFPA, ULC, and local codes. Our team uses advanced 3D modeling and hydraulic calculations to verify system performance and compliance before installation.
NFPA 20 requires that a listed fire pump must produce at least 65% of its total rated head when operating at 150% of rated capacity, and the shutoff (churn) head cannot exceed 140% of rated pressure. The performance curve is a basic design constraint — a fire pump system designer must select a pump/driver combination that can meet both ends of that curve, not just the rated duty point.
NFPA 20 allows for testing (and thus design) for a reduced maximum flow condition where the water supply truly cannot provide 150% of the rated pump flow – the system is tested at the maximum flow the supply can actually provide. The implication is that a limited water supply does not disqualify a design but it must be explicitly reflected in the engineering documentation rather than assuming full-curve performance is feasible.
NFPA 20 calls for a weekly run test of diesel-driven fire pump engines with a minimum run timer of at least 30-minutes, enough time for the engine to reach normal running temperature. This is important at the design stage because the ventilation, cooling and exhaust systems for the pump room will all need to be sized for a full 30-minute run under load, rather than a brief start-up cycle.
NFPA 20 requires that the motor current be verified for a minimum of 30 minutes during testing to ensure that the motor is operating within its rated limits over a period of time and not just at startup — a consideration that affects how electrical engineering coordination (breaker sizing,
thermal protection settings) should be documented in the design package.
NFPA 20 recognises the vertical shaft turbine type pump as a distinct equipment category to be used where the water supply is below the pump, i.e. drafting from an underground reservoir. Other pump types share the same 140% shutoff head limitation, but the engineering issues of submergence depth, column length, and suction conditions are unique to this configuration and do not carry over directly from a horizontal split-case pump design.
