How Much Does a Structural Engineer Charge in Ottawa?

A big part of the costs that come with the job of a structural engineer has to do with the complexity of the project. 

For instance, basement structural projects will definitely cost more because it requires foundational assessment and repair. Of course, it goes without saying that commercial projects are costlier than residential ones, as well.

To know some of the estimated costs of common structural engineering services, we researched some national averages and put them in the table below.

Residential project$680 – $8,500 (depending on complexity, size, location, and job type)
$170 – $350 per hour
Structural engineer inspection$400 up
Structural engineer report$2,000 up
Load-bearing walls$700

Please note that inspections, assessments, consultations, and reports could vary per structural engineer. It’s still best to inquire about the costs of different services before getting them for a project.

Customer Reviews

Impressive, professional, very courteous

“Sam was such a pleasure to work with. We had an urgent and unexpected need for an engineering report. He made time for us immediately and turned his full report around so quickly. We were so grateful. I happened to spend several hours with him as he completed his site visit and research. He’s an impressive professional and very courteous. He’s both a PEng and a Ph.D. We priced out three engineers and he was the most reasonably priced, too.

All in all, I can’t recommend Sam enough.” – Elena Aptowitzer

The epitome of professionalism

We had Sam at our commercial property to inspect the beginnings of a hole under our parking structure. As it was an urgent safety matter, he came as soon as he could and was the epitome of professionalism. The assessment and report were thorough, and he turned everything around to us in a timely manner.

We highly recommend using OSES for any of your structural engineering needs! Thank you, Sam!” – fncaringsociety
