From existing-condition investigations, load calculations and capacity planning to permit drawings, tender support and construction coordination. ETEM develops electrical systems around the building, the code and the way the project will actually be delivered.
Motor controls, disconnects and feeders sized from the mechanical equipment data, so electrical and mechanical requirements match on site.
50+ municipal facilities
Fire alarm design, emergency and exit lighting upgrades and power distribution across community centres, fire stations, arenas and recreation complexes, with P.Eng.-stamped permit drawings.
Key systems: LED conversion, Lighting controls, OBC SB-10
Interior and exterior lighting redesign across school board facilities, with occupancy and daylight sensors and energy-code compliance.
400–4,000 A service entrance design
Utility metering configurations, transformer sizing, switchgear specification and coordination with Toronto Hydro, Alectra and Hydro One connection processes.
Drawings, site conditions, occupancy, operating issues and owner priorities are reviewed first.
System options, design criteria, preliminary loads and major space requirements are set early.
Layouts, schedules and risers are developed with the architecture and issued for permit.
Tender questions, submittals, RFIs and site issues are answered within the agreed scope.
No. ESA states that plan review is not a substitute for Professional Engineer design. The engineer remains responsible for the engineering documents within the professional scope.
Yes. ESA's current guidance says a single-line diagram is required in every plan-review submission. The package also needs the current submittal form and supporting information for the project type.
Common triggers include obsolete or unsupported equipment, recurring deficiencies, renovation or change-of-use work, poor replacement-part availability, capacity limitations and interface changes. Start with an engineering assessment rather than a product selection.
Connected load is the sum of all equipment nameplate ratings. Demand load applies CEC demand factors to reflect that not all equipment runs at the same time. Service entrance sizing uses the demand load.
Not always. A load calculation shows whether the existing service and panel have capacity, and an electric vehicle energy management system (EVEMS) under CEC Section 86 can share that capacity among chargers.
Yes. They can be reviewed within the same life-safety capital project because access, phasing, emergency power and permit coordination may overlap. They remain separate systems with their own requirements.
