The big idea
Stage 1 is the foundation of everything. What is built above ground depends on the accuracy, quality and safety of the work done here. The stage covered the full workflow: permits, plans, ground preparation, forms, rebar, concrete, waterproofing, drainage, backfill, insulation, anchoring, and the tools, gear and safety to do all of it properly. Every later stage depends on it, and mistakes here carry through the whole build.
What you learned
- Permits and approvals: what you need and when. Permits
- Plan reading and layout: Plan Reading, Elevation and Layout.
- Ground preparation: Soil Types, Trench Safety, Water Control.
- Footings and forms: Footing Forms through Retaining Wall Forms.
- Rebar: Rebar Placement, Chairs and Spacers.
- Concrete: Delivery, Slump, placing, Vibration, finishing, Weather Adjustments.
- Waterproofing and drainage: Membranes, Drain Tile, Sump Systems.
- Backfill, compaction and insulation: Backfill Types, Lift Thickness, Foundation Insulation.
- Anchoring and tie-ins: Anchor Bolts, Seismic and Wind Tie-Ins.
- Tools, gear and safety: Excavation Tools through Tool Belt Loadout.
Common Stage 1 mistakes
- Poor elevation control, so the foundation is uneven
- Wrong rebar spacing, cover or missing tie-ins
- Weak forms that bow or blow out
- Poor vibration, causing honeycombing
- Skipping waterproofing or drainage steps
- Backfilling too early or without proper compaction
- Anchor bolts in the wrong place
- Digging before the locate is done
- Working in an unsupported trench
- Ignoring the weather
- Using numbers from a US guide or another province instead of your own code and OHS regulation
They plan layout and elevations before touching a shovel, confirm permits first, read the plans and ask when something is unclear, build straight, square forms, tie rebar cleanly, pour with control, protect the foundation with waterproofing and drainage, compact in correct lifts, adjust for the weather, and keep records and photos.
Before you move on
- Look up the current building code for your province and your provincial OHS regulation for every item marked Confirm in this stage, for your own project.
- Check your municipality's requirements, which may add to or change the code.
- Where the drawings or an engineer give a number, the drawings win.
With Stage 1 done, you are ready for Stage 2: Structural and Building Envelope Systems. The skills you built here support every step of the build.

Stage 1 follows the National Building Code Part 9 model as each province or territory adopts or amends it, and each has its own OHS regulation and one-call locate service. The editions and rules are on the Permits and Canada by Province lessons, where they were checked. I dropped the old per-province code and fall-protection list on this page because I could not verify it all again here. Confirm with your building department and provincial regulator.
- This page recaps the lessons above. Each lesson lists its own sources and marks what was not verified.
