Plumbing Estimating Softwarefor Ottawa Contractors
If you're bidding plumbing in Ottawa, the gap between a job that nets margin and one that doesn't usually comes down to underestimating fitting counts — and how you handle heavy snowfall requires robust snow removal planning. Drop a plan set in, walk away for 10 minutes, come back to a priced bid you can defend.
What Ottawa does to a plumbing bid
Cold winters with heavy snow, warm humid summers. Toronto, Montreal, Ottawa region.. Temperatures swing -15°C to 30°C (5°F to 86°F), rainfall runs 800-1000mm (31-39 inches), and inspectors here are working off OBC/NBCC Part 9. None of that shows up on a plan symbol legend — but it changes your fastener schedule, your waste factor, and whether the building department signs off on the rough.

Things that bite Ottawa plumbers on the rough
Field-level notes for plumbing work in Continental (Canada) conditions — anchored to OBC/NBCC Part 9.
Watch-out specific to this market
Underestimating fitting counts. In Ottawa that gets worse because heavy snowfall requires robust snow removal planning, and OBC/NBCC Part 9 (frost line 1.2–1.8 m, R-60 attic, EnerGuide labelling, ice-and-water at eaves) won't let you patch around it after the fact. Catch it at takeoff or eat it on the punch list.

Stuff Ottawa plumbers ask before they sign up
Does this respect ON code, or do I have to re-cut every quantity?
Counts assume OBC/NBCC Part 9 (frost line 1.2–1.8 m, R-60 attic, EnerGuide labelling, ice-and-water at eaves). ON doesn't license plumbing at the state level, so the variability comes from local amendments. Quantities are correct; you adjust crew rates and local permit assumptions in the bid summary.
How do you handle counting fixtures across multiple floors?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For government work in Ottawa, the typical correction is one or two assemblies — not redoing the whole thing.
What about heavy snowfall requires robust snow removal planning?
Steep pitches (6:12+) recommended for snow shedding. Ice and water membrane required on eaves. Metal roofing popular in rural areas. CertainTeed and BP products dominate market.
How much does a permit add to a plumbing job around here?
