Engineer of Record

When a Project Needs a Stamp, Not a Firm

Many projects stall not because the engineering is hard, but because the design team doesn't have a licensed P.Eng who can take responsibility for the electrical scope. RHEM fills that gap.

📝

EOR for Contractors

Your install team knows what they're doing. You just need someone licensed to sign the drawings so the permit gets approved.

We review contractor-prepared designs, ask the right questions, make any required modifications, and stamp drawings for permit submission. We're not here to redo your work. We're here to stand behind it professionally.

Solar PV systems where the installer needs stamped drawings for ESA / building permit

EV charging installations requiring electrical permit drawings

BESS systems requiring structural and electrical P.Eng review

Generator and standby power installations

Industrial electrical modifications above 750V

What's Required from You

Complete design package, site photos, load calculations, equipment specifications, and the installer's willingness to address any deficiencies we identify.

🏗

EOR for Developers & GCs

Development projects that need an independent electrical P.Eng without the overhead of a full MEP firm on retainer.

We embed as the electrical EOR for your project: attending design meetings, reviewing shop drawings, responding to RFIs, and conducting site reviews at key milestones. Flexible engagement structures from fixed-fee to hourly retainer.

Multi-family residential electrical service design

Commercial tenant improvement electrical

Industrial facility expansions and modifications

Renewable energy projects requiring independent review

Peer review of designs prepared by others

Typical Engagement

Monthly retainer from $2,500 for ongoing projects, or milestone-based fees for defined scopes. Initial consultation always free.

Why EOR Matters

A P.Eng stamp isn't just paperwork.

In every Canadian province, electrical systems above a certain complexity require a licensed professional engineer to take legal responsibility for the design. Without it, permits get rejected, insurance may be void, and if something goes wrong, liability falls on the contractor or owner, not an engineer who isn't there.

EOR RESPONSIBILITY INCLUDES

Design correctness, code compliance, safety, constructability, and professional liability for the life of the installation.

WHEN YOU NEED AN EOR

Building permits, utility interconnection applications, ESA registration, insurance requirements, or any project with public safety implications.

Opening the Gates

Stuck Projects. Cleared.

Between a good idea and a working system stand a row of gates: utility queues, permit offices, inspection bodies, and regulators who need the right documents before they'll move. We know how each one works, what they actually want to see, and how to get through without losing months.

🔗

Utility Interconnection

The utility's interconnection queue is where solar and storage projects go to wait, sometimes for years. We prepare the technical package (SLD, protection relay settings, site plan, load calculations) that moves your application from the back of the queue to approved.

🏛

Permits & Municipal Approvals

Building permits, electrical permits, ESA inspection, zoning variances. We prepare drawings and documentation to the standard each authority actually accepts, not a generic package that gets kicked back on the first review.

📋

Incentive Pre-Qualification

Federal and provincial programs (ITC, saveONenergy, CleanBC, TIER) have technical eligibility requirements buried in their program guides. We document the technical case that confirms your project qualifies before you apply, so the money isn't at risk after the work is done.

The Gates We Open

Every clean energy and electrical project runs into at least one of these. Most run into several. None of them are impossible: but they all require the right documentation, the right contacts, and the experience to know what each gatekeeper actually needs.

🔋 IESO / Grid Operator

Market registration, connection impact assessment responses, technical requirements for behind-the-meter and grid-export BESS.

🏗 Authority Having Jurisdiction

The AHJ can approve or kill a project on a technicality. We speak their language: stamped drawings, code citations, and a clear technical record they can sign off on.

💰 Incentive Administrators

NRCan, provincial energy offices, and utility DSM teams all have technical reviewers. We prepare the measurement and verification documentation that gets claims paid.

🏢 Landlords & Property Owners

Tenant-side improvements need landlord sign-off. We prepare the technical summary and risk briefing that gives property owners enough confidence to say yes.
