What it isA recap of all of Stage 1, from permits to the tool belt, with links back to every lesson.

The hard ruleThe drawings, the engineer and your provincial code and OHS regulation beat anything in this book.

The checkEvery item marked Confirm has been looked up for your own project.

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

What pros do differently

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.

✅ You are ready whenTap your level

Home DIY

You can say which parts you will do and which need a permit, an engineer or a licensed trade. You have called the locate service, you treat 1.2 m (4 ft) as your own no-entry line for trenches and will not judge sloping or shoring yourself, and you know your inspection stages.

Laborer or helper

You know which tasks you do under direction and which you never do alone. You never enter an excavation that a qualified person has not sloped or shored, you know what locate marks mean, you wear your PPE, and you speak up and stop when something looks wrong.

1st-year apprentice

You can read a foundation plan, lay out lines and elevations, build a simple form, tie rebar and place concrete under supervision. You wear the right PPE and know when to ask.

Apprentice, 2nd to 4th year

You can do your tasks to the plans under a journeyperson: forms, rebar, waterproofing, drainage and anchors. You never judge a trench or platform as safe, and you know which inspections the work must pass.

Journeyperson

You can plan the sequence, check forms, rebar, waterproofing, drainage and anchors against the plans and your provincial code, and run your own readiness check before each inspection. You know where you must stop for an engineer or an inspection.

Lead hand or foreman

You check the crew's work against the plans before it is covered and call each inspection. You enforce the stop-work triggers, you know when to stop for an engineer, and you do not override one.

Contractor or business owner

You have the permits, insurance, workers' compensation registration, safety program, locates and records in place. You know your province's inspection stages and warranty rules, and you price the unknowns.

Starting a new business

You have confirmed your permits, locates, inspection stages, workers' compensation registration and insurance with the authorities. You have lined up engineers and subcontractors for the work you cannot do, and a written safety program and records.

By Province:

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.
