Scaffold collapses and falls from height remain leading causes of serious injury and death on construction sites. A structured scaffold inspection before each work shift catches defects, missing components and unauthorised modifications before workers step onto the platform.
This guide walks through the complete scaffold inspection procedure, from foundations through to tagging. It covers tube-and-coupler, modular and system scaffold types and references both Australian (AS/NZS 1576) and US (OSHA 1926 Subpart L) requirements.
Before you start
Gather your scaffold inspection checklist, a pen and a measuring tape. If you need to access scaffold platforms above 2 metres, wear appropriate PPE including a harness if edge protection is incomplete or being verified.
Only a competent person should conduct scaffold inspections. In Australia, this means a licensed scaffolder or a person with equivalent scaffold safety training. In the US, OSHA requires a competent person as defined in 1926.450(b). Review the scaffold design drawings or plan before you begin so you know the intended configuration.
Step-by-step inspection
1. Check foundations and base plates
Start at ground level. Inspect the bearing surface under each standard. The ground must be firm, level and capable of supporting the scaffold load without settlement. Base plates should sit flat and be centred on sole boards where the ground is soft or uneven.
- No sinking, tilting or displacement of base plates
- Sole boards are adequate size and in good condition
- Screw jacks (if used) are not extended beyond their safe limit
2. Inspect standards and ledgers
Check every vertical standard for plumb. Standards that lean or bow indicate foundation movement or overloading. Inspect all horizontal ledgers for secure coupler connections at every standard intersection. Look for bent, dented, cracked or heavily corroded tubes.
3. Check bracing
Diagonal bracing prevents the scaffold from racking sideways. Verify braces are fitted on both faces and at each lift level as per the design. Check that all brace couplers are tight and that no braces have been removed to create access or to run services through the scaffold.
4. Verify platform boards and guardrails
Walk each working platform. Boards must be fully decked with no gaps wider than 25 mm. Check guardrails are fitted at every open edge at a height of 900 mm to 1,100 mm (Australia) or 38 to 45 inches (US). Mid-rails and toe boards (minimum 150 mm high) must be in place.
- No split, warped or broken boards
- Board overhang does not exceed four times board thickness
- No unsecured materials or debris on platforms
5. Inspect access ladders or stairs
Confirm safe access to each platform level. Ladders must be secured to prevent movement and extend at least 1 metre above the landing platform. Stair towers should have handrails on both sides. Trapdoor hatches in platforms should self-close or be secured when not in use.
6. Check ties and anchors to the building
Ties and anchors connect the scaffold to the permanent structure. Check that ties are installed at the spacings shown in the scaffold design and that fixings are tight. Ties should never be removed without the scaffolder's approval. Loose or missing ties are one of the most common causes of scaffold collapse.
7. Record and tag the scaffold
Complete the inspection register. Attach the appropriate scafftag or sign: green (safe to use, inspected), yellow (modifications required, restricted use), or red (unsafe, do not use). Include the date, inspector name and next inspection due date. Use a digital inspection form for faster record-keeping.
Common scaffold failures
| Failure mode | Root cause | What to check |
|---|---|---|
| Foundation settlement | Soft ground, undersized sole boards | Base plates, sole boards, ground condition |
| Racking collapse | Missing or removed bracing | Diagonal braces on both faces |
| Platform failure | Overloading, damaged boards | Board condition, load signage |
| Falls from height | Incomplete guardrails | Top rail, mid-rail and toe board at every edge |
| Separation from building | Missing or loose ties | Tie spacing and fixing tightness |
Inspection frequency
| Trigger | When |
|---|---|
| Before first use | After erection, before any workers access the scaffold |
| Routine | Before each work shift (OSHA) or weekly (AS/NZS 1576) |
| After weather event | High winds, heavy rain, storms |
| After modification | Any alteration to structure, height or configuration |
| After incident or impact | Vehicle strike, dropped load, earthquake |
Standards and regulations
In Australia and New Zealand, AS/NZS 1576 governs scaffold design, erection and use. Part 1 covers general requirements and Part 4 covers hanging scaffolds. AS/NZS 4576 provides guidelines for scaffolding safety. Scaffolders must hold a High Risk Work licence for the appropriate class (SB, SI or SA).
In the US, OSHA 29 CFR 1926 Subpart L sets construction scaffold requirements. Section 1926.451(f)(3) requires inspection by a competent person before each work shift, and section 1926.451(f)(7) requires defects to be rectified immediately.

Going digital with MapTrack
Paper scafftags fade in the weather and inspection registers disappear from site offices. With MapTrack, each scaffold carries a QR code tag that inspectors scan to open the inspection form on their phone. The system captures the timestamp, inspector name and GPS location automatically.
Overdue inspections trigger automated alerts to the site supervisor, and the full inspection history is stored in compliance reporting for principal contractor audits and regulator requests.
