Inspection

Inspection Steps in Wooden Buildings in Canada:

1) Footing Stage:

Preparation for Inspection:

Ensure the excavation site is clear and the footing forms are properly laid out with the correct placement of rebar as per engineering specifications.
The inspection should be scheduled before pouring the concrete.

During the Inspection:

The inspector verifies the size, depth, and placement of footings relative to the property lines and building layout.
The footing design, including rebar arrangement, must comply with the drawings approved by the engineer.

2) Foundation Wall:

Before Concreting:

Schedule an inspection to check foundation wall rebar placement before concrete is poured.
Provide the inspector with photos or access as proof of compliance.

Inspection Considerations:

The inspector will check for proper rebar positioning, size, and quantity to ensure it meets structural requirements.

3) Prebackfill:

Preparation for Inspection:

Apply waterproofing and dampproofing membrane to the foundation walls.
Install weeping tiles or foundation drains and cover with gravel to ensure proper drainage.

During the Inspection:

The inspector checks the waterproofing, drainage, and damp-proofing for integrity and proper installation.
Additional checks may be performed for foundation depth, setbacks, and if the basement height is a concern, ensuring it is not misclassified as the first floor due to excessive height.

4) Framing, Plumbing, and HVAC:

Concurrent Inspections:

The framing, plumbing, and HVAC are typically inspected together.
Ensure that the structural framing is complete with all necessary blocking, bracing, and fire stopping.

Plumbing and HVAC:

The plumbing rough-in, which includes the installation of drain and water pipes, is inspected for proper slopes and support.
HVAC ductwork and equipment should be installed and ready for inspection.

5) Electrical Rough-In:

By Certified Electrician:

The Electric Safety Authority (ESA) will be called by the licensed electrician for the rough-in inspection.
The inspector will verify correct wiring, junction boxes, and panel installation.

6) Insulation:

Preparation for Inspection:

Insulate the building according to the local code requirements.
The vapor barrier must be installed properly to avoid any possible moisture issues.

7) Fire Separation:

If Applicable:

Depending on the proximity to adjacent buildings, a fire separation inspection may be necessary.
This involves verifying fire-rated construction between units or properties.

Additional Steps:

Gas Inspection:

Enbridge usually conducts their inspections for gas, checking for plumber labels and installation tags.

Drainage:

Have the in-floor drainage inspected before it’s covered, ensuring the slopes are correct directing water appropriately outside.

Fire Alarm and Carbon Monoxide Detectors:

Ensure smoke alarms and carbon monoxide detectors are in place and functional.

8) Final Inspection:

Completion Checks:

Railings, guards, hot water supply, P-traps, cleanouts, and backwater valves are checked for proper installation.
Enbridge labels and furnace sizing are verified.

Occupancy Permit:

The building must pass all inspections, and then the inspector can issue the occupancy permit, allowing residents to legally occupy the building.

General Tips:

Documentation:

Keep engineering reports, permits, and photos ready for each stage of inspection.

Coordination:

Schedule inspections well in advance and ensure the site is prepared and accessible for the inspector.

Compliance:

Follow all recommendations by inspectors and correct any issues immediately to avoid delays in receiving clearance to proceed.

Shoring (if applicable):

If shoring is required for excavation, an inspection will need to take place before this stage begins.

Following these inspection steps ensures your wooden building project in Canada abides by the strict regulation frameworks established within the industry to assure safety, quality, and structural integrity. Always maintain clear communication with your local municipal building department for any region-specific requirements.
