Structural engineering

The structure should be the easy part.

Residential and commercial structural engineering across Ontario. Inspections, drawings, load calcs and permit support — handled by a P.Eng with nine years stamping Ontario builds.

Structural Inspections

Pre-purchase, pre-renovation, insurance-driven, and post-incident inspections. Plain-English findings with a clear recommendation.

Renovation & Addition Drawings

New beam runs, opened-up walls, second-storey additions, structural retrofits. Stamped and detailed for your contractor.

Load Calculations

Snow, wind, seismic and live-load calcs for additions, decks, roof loads, equipment mounts, and accessory structures.

Permit Support

Drawings packaged the way Ontario building officials want them. We know the quirks in 40+ municipalities.

Commercial Work

Tenant fit-outs, change-of-use, mezzanines, mechanical equipment supports. Smaller commercial done well.

Site Visits

On-site within the week for most of Barrie, Muskoka, Simcoe and the GTA. We come and look — drawings get better.

Fixed scope. Real timelines. No drift.

We quote on the call. Drawings start the week your engagement letter is signed. If the project changes, we requote — no hidden hours.
