Lands on the critical path
A Geotechnical Investigation in Quebec covers the following. Boreholes and test pits to characterise soil stratigraphy, bearing capacity, groundwater elevation and settlement risk, with foundation recommendations and excavation guidance.
On land acquisitions, redevelopment sites, additions, and any deal where a foundation or below-grade structure is part of the plan. In Quebec the statutory backdrop is the Environment Quality Act (EQA, ss. 31.51–31.53 (cessation of a designated activity)), administered by Ministère de l'Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs.
Envirolor models this report at $7,600–$39,900 in Quebec on a flagged 50,000 sf industrial asset, with a 27-day turnaround. The regional cost index of 0.95 and a 2-day scheduling penalty on intrusive work are both applied. Cost scales with floor area at an elasticity of 0.30, so a building twice the size is not twice the fee.
Where deals break on this report: Rig mobilisation to a remote or constrained site, and the discovery of fill that turns a routine foundation into a piled one after the price is already agreed.
Sequencing matters more than price here. This is a stage-two report: it cannot be engaged until the stage-one findings exist, so it lands on the critical path in full. In Quebec, ceasing a designated industrial or commercial activity compels a characterisation study within six months — a statutory Phase II with no discretion — and a change of use on a listed site triggers the same obligation.
Envirolor facts
- Geotechnical Investigation is a tier-2 report in the Envirolor catalogue.
- Quebec applies a cost index of 0.95 and a 2-day scheduling penalty to intrusive work.
- Filing route in Quebec: Characterisation study and, where contamination exceeds criteria, a rehabilitation plan and notice on title.
How these figures were produced
- Modelled — Derived arithmetically from observed inputs using the published method; not a market quote.
- Baseline seed — A documented starting estimate awaiting first observation. Treat as an order-of-magnitude figure only.
02Scope of work
What the consultant actually does
Boreholes and test pits to characterise soil stratigraphy, bearing capacity, groundwater elevation and settlement risk, with foundation recommendations and excavation guidance.
Where it goes wrong: Rig mobilisation to a remote or constrained site, and the discovery of fill that turns a routine foundation into a piled one after the price is already agreed.

Scope fits
| Report | Status | Cost band | Days | Lands |
|---|---|---|---|---|
| Roof / envelopeA 41-year-old roof is usually the largest single line in the reserve table; a dedicated review turns a range into a number. | Recommended | $2,400–$10,500 | 13 | Day 13 |
| DSS / hazmatA 1985 building is pre-ban construction: the survey is legally required before any renovation or demolition is tendered, and the abatement number belongs in the purchase price. | Required | $2,700–$12,400 | 15 | Day 15 |
| Phase I ESAEvery lender on a commercial file requires a Phase I addressed to it with reliance, dated within six months of funding. | Required | $2,100–$5,200 | 16 | Day 16 |
| BCA / PCAThe lender's reserve requirement is set off the BCA's capital table, so it is a funding condition, not a nice-to-have. | Required | $3,300–$13,300 | 19 | Day 19 |
Out of scope, and why
- Phase II ESA — No area of potential environmental concern was flagged, so the Phase I should close without sampling. If it does not, add roughly the Phase II band to both cost and calendar.
- Geotech — An existing building with a known grading history rarely needs a geotech at acquisition; add one before any addition.
- Elevator — No elevating devices in the asset.

Scope of work
1. Roof and Building Envelope Review — Recommended
Roof-level inspection with core cuts where warranted, moisture scanning, flashing and parapet review, and an envelope assessment covering cladding, sealants and glazing, with remaining service life and replacement cost.
$2,400–$10,500 · engage day 0 · draft day 13
2. Designated Substance and Hazardous Materials Survey — Required
Bulk sampling and laboratory analysis for asbestos-containing materials, lead, mercury, silica and other designated substances, producing the inventory that must be handed to any contractor before demolition or renovation.
$2,700–$12,400 · engage day 0 · draft day 15
3. Phase I Environmental Site Assessment — Required
Records review (fire insurance plans, aerial photography, title, environmental registries), a site reconnaissance visit, and interviews with the owner, occupants and the municipality. The deliverable identifies areas of potential environmental concern (APECs) and states whether intrusive investigation is warranted.
$2,100–$5,200 · engage day 0 · draft day 16
4. Building Condition Assessment — Required
A walk-through of structure, envelope, roofing, mechanical, electrical, vertical transportation, life safety and site works, followed by an immediate-repair list and a capital reserve table projecting replacement costs over the study period.
$3,300–$13,300 · engage day 0 · draft day 19
Verdict
This scope runs 3 required and 1 discretionary report, for a modelled $10,500–$41,400 and a 24-day critical path from engagement to a reviewed set of drafts.
Against the 45-day condition period entered, that leaves 21 days of slack — enough to absorb one lab delay, not two.
No area of potential environmental concern was flagged, so the base case is a Phase I that closes clean. If it does not, the Phase II adds roughly 30 days and the sampling band to this answer.

04Questions
How much does a Geotech cost in Quebec?
$7,600–$39,900 on a flagged 50,000 sf industrial asset, modelled by Envirolor from published cost bands with a 0.95 regional index applied. Smaller assets sit below the band; the fee does not scale one-for-one with area.
How long does it take in Quebec?
27 calendar days from engagement to draft, including the 2-day Quebec scheduling penalty applied in full to intrusive work.
What forces this report in Quebec?
Ceasing a designated industrial or commercial activity compels a characterisation study within six months — a statutory Phase II with no discretion — and a change of use on a listed site triggers the same obligation.
