About this service

Most homes don't need an engineer, but some do: large custom homes, garden and secondary suites, and service upgrades where the utility or the municipality asks for stamped drawings.

We prepare load calculations and drawings that show exactly what's being added and how the existing service supports it, whether that's a 200 A to 400 A upgrade, a detached garden suite, EV chargers, solar or a standby generator with transfer switch.

Drawings are kept practical and buildable so your electrician can work from them directly, and we turn them around quickly so the permit isn't what holds the project up.

What we design

When a home needs stamped electrical drawings, usually for a large custom build, a garden suite or a service upgrade, we prepare them quickly and in a form your electrician can build from.

Custom homes, garden suites and service upgrades

Homeowners and builders in Edmonton call us when a project needs more than a standard permit: a garden or basement suite on an existing service, a large custom home, a heat pump or EV charger addition, or a service upgrade. We calculate the load, confirm what the existing service can carry and lay out exactly what needs to change.

Our sealed drawings give your electrician and the permit office a clear scope, and help you avoid discovering a needed service upgrade halfway through construction.

We provide electrical engineering services in Edmonton, St. Albert, Sherwood Park, Spruce Grove, Stony Plain, Leduc, Beaumont and Fort Saskatchewan, and take on projects anywhere in Alberta. Start a project or call 780-919-9696.
