Excavation Barrie

Before a bucket touches a Barrie lot, several clocks have to run out: at least five business days for utility locates, about five more for a City right-of-way permit, and whatever a conservation authority needs if the lot is regulated. Excavation in Barrie is governed less by the ground than by the paperwork that has to clear before a bucket touches it, and by the rules on where the soil goes afterward.

We are a design-build firm, and on our projects excavation is one part of the site work rather than a stand-alone trade. Our owner, Rene Ouellet Jr., oversees site preparation, excavation and foundations. Much of the site work our own pages describe is on rural and cottage-country lots, where the job is clearing, rock, a well and a septic bed. Inside Barrie, with municipal services in the street and neighbours a few metres away, the order of operations changes, and this page walks through it.

The City’s grading bulletin for residential projects lists when a grade plan has to be submitted: for infill houses, for detached secondary dwelling units, for additions over 37.2 m², and for any project where excavation, other than pier footings, comes within 1.2 metres of a property line. That last trigger is the one that catches Barrie lots.

Barrie’s zoning by-law sets a 1.2 metre minimum side yard in its R1 to R4 single-detached zones, and its smaller zones allow lots as narrow as 10 to 12 metres. A house built to the minimum side yard puts its foundation wall right at the distance where the trigger sits, so a basement dug on a tight lot almost always reaches it. On an infill lot the question is already answered, because infill houses need a grade plan regardless.

The grade plan has to come from a professional engineer, a certified engineering technologist, an Ontario land surveyor or an architect. It shows existing and proposed grades, the swales that carry water and which way they slope, where the sump pump discharges, and the underside of footing, top of foundation wall, known high water table and finished floor elevations. In other words, it fixes how deep the excavation goes before the excavation starts. In 2026 Barrie charges $579.43 for a grading review on projects outside site plan, condominium or subdivision review.

That is why we do not quote a depth from the curb. The footing elevation on an approved grade plan is the number the dig is built to.

On our own projects the dig is scheduled from the permit backward, not from the excavator’s availability forward. The sequence on a Barrie lot looks like this: settle the zoning and the applicable law questions, have the grade plan drawn, file the building permit, apply for the ROWA permit and request locates so both land before the date, then excavate to the approved footing elevation and move straight to the foundation.

Doing it as one team matters most at the hand-offs, and a Barrie infill dig has more of them than a rural one. The person who reads the grade plan is the person who books the machine and the person who checks the footing elevations before concrete. On our sites that is Rene Ouellet Jr., who brings decades of hands-on experience to site preparation, excavation and foundations. Our own build process lists the site work stage plainly: lot clearing, blasting where there is rock, excavation, septic, well, driveway and foundation. Inside Barrie, with water and sewer in the street, the well and septic usually drop off that list and the right-of-way work takes their place.

The nearest finished projects on our Our Work page are two 2018 homes in Oro-Medonte, The Carlyle MKIII and The Bayview, the second with a slab-on-grade walkout. Our office and model home are in Innisfil, at 1942 Commerce Park Drive.
