Common questions

Electrical engineering questions for this scope.

Which services are the strongest fit?

The strongest fit is commercial and contractor-led electrical design: multifamily, commercial tenant improvements, EV charging, service upgrades, generator/ATS work, and design-build permit packages.

Are small permit support jobs still accepted?

Yes, when they fit the schedule and technical scope, but this site is primarily positioned for commercial, multifamily, and contractor/developer projects.

Can multiple states be supported?

Yes. PNW Electrical Engineering is licensed for electrical engineering support in Washington, Oregon, Idaho, and Nevada.

How are fees handled?

Most appropriate projects can be reviewed for a fixed-fee proposal with clear deliverables, exclusions, schedule, and permit review response assumptions.
