Engineering That Moves Projects Forward

52 services across engineering, environmental, and health & safety. P.Eng licensed in Ontario, delivering across Canada: solar, electrical, power systems, BESS, lighting, environmental assessments, and safety programs.

Engineering That Gets Projects Unstuck

Too many good projects stall, not because the technology doesn't work or the numbers don't pencil out, but because the engineering, permitting, safety, and utility documentation wasn't in place.

RHEM exists to remove those gates. Our founding engineers bring hands-on experience across 2.58 GW of solar and power systems projects. We deliver P.Eng sealed drawings, power studies, safety programs, and interconnection packages that move projects from concept to commissioning without the overhead of a large firm.

Every engagement is treated the same: professional quality, transparent pricing, honest timelines, and a named engineer you can actually talk to.

Not a Large Firm. Not a Solo Practitioner. Something Better.

🎯

Focused Specialization

52 services across engineering, environmental, and safety, selected deliberately because they interconnect. The arc flash study informs the LOTO procedures. The solar design informs the electrical service sizing. The Phase I ESA informs the site remediation plan. You don't have to brief three firms on the same project.

💬

Direct Engineer Access

You communicate directly with the engineer doing the work, not a project manager relaying messages. Questions get answered the same day. Site conditions that change get incorporated without a change-order process that takes a week.

📐

Transparent Pricing

Tiered pricing with honest upfront estimates. No surprises. No hidden fees for "additional coordination" that should have been in scope. The estimating tool on this site exists because we believe you should know roughly what you're committing to before you sign anything.

🛠

Industry-Standard Tools

HelioScope, PVsyst, ETAP, DIALux, RETScreen, AutoCAD. The same tools used by the largest engineering firms. Results that pass utility review, AHJ scrutiny, and financing due diligence.

🛡

Safety Built In

Safety documentation isn't offered as an upsell. It's integrated into every EoR and construction-phase engagement. If we're signing drawings, we're also helping make sure the people installing them can do it safely and legally.

🌐

Pan-Canadian Delivery

Remote-first practice with tools and relationships across all provinces. Ontario, BC, Alberta, and beyond. We track provincial code differences, rebate program changes, and utility interconnection requirements so you don't have to.

From First Contact to Stamped Deliverables

1
Free Feasibility (Solar) or 15-min Scoping Call
Start with our free solar feasibility tool or book a 15-minute call. We'll understand your project, identify the right services, and give you a realistic estimate, no obligation. We'll also tell you honestly if your project isn't a good fit.
2
Scope of Work & Proposal
We send a clear, itemized scope of work and fixed-price quote. No hourly rate mystery. You know what you're getting and what you're paying before you commit.
3
Data Collection & Site Assessment
We collect the data we need: utility information, building documents, equipment data, site access. Drone surveys for solar projects. We minimize back-and-forth by being specific about what we need and when.
4
Engineering & Production
The actual work: modelling, analysis, calculations, drawing production. You're updated at key milestones, not kept in the dark. Preliminary results shared before final deliverables for your review.
5
Review Cycle & P.Eng Seal
Your review cycle(s) are built into the scope. Comments incorporated efficiently. When everything is right, the P.Eng seal goes on and deliverables are issued.
6
Construction Support & Closeout
RFI responses, field questions, utility coordination, commissioning witness, all included in Standard and Premium tiers. The relationship doesn't end when drawings are issued.
