QR codes for construction sites
Construction sites run on documents that change weekly: method statements, risk assessments, permits, drawings. A QR code on the site board or a piece of equipment can open the current version, so nobody works from a printout that was superseded last Tuesday.
The hoarding around a site is also the developer's biggest billboard. A code there can open the sales page for the homes being built, or a page explaining the works to neighbours.
QR code ideas for construction
Site induction
A code at the gate that opens the induction video and sign-in form for visitors and subcontractors.
Current safety documents
Risk assessments, method statements and emergency contacts behind codes on the site board.
Equipment checks
Tags on scaffolds, ladders and plant that open the inspection checklist and the latest inspection record.
Hoardings and neighbours
Sales pages for the development, or a page with working hours and a contact for complaints.
Which QR code to use
Static codes are free and need no account, but can't be changed after printing. Dynamic codes and hosted pages can be edited at any time, count every scan, and keep working on every plan, even if you cancel.
PDF page
An uploaded PDF people can read in the browser or download.
Drawings and safety documents replaced as they are revised, so the printed code always opens the current issue.
Build it in the dashboardVideo page
A YouTube or Vimeo embed, or an uploaded MP4.
Induction and toolbox-talk videos that play in a browser at the gate.
Build it in the dashboardFeedback and forms page
Star ratings, NPS and questions, with responses collected in your dashboard.
Sign-in, inspection and near-miss forms with choice and text fields, exportable for the site file.
Build it in the dashboardBusiness page
Opening hours, address with a map link, contact buttons and amenities.
For hoardings facing neighbours: working hours, site contacts and the address in one place.
Build it in the dashboardHow big to print it
| Where people scan | Distance | Minimum code width |
|---|---|---|
| Equipment tag | 50 cm (20 in) | 5.8 cm (2.3 in) |
| Site board at the gate | 1.5 m (5 ft) | 17.4 cm (6.9 in) |
| Hoarding, from across the road | 8 m (26 ft) | 92.8 cm (3.0 ft) |
For a dynamic short link such as https://qrdx.dev/q/aB3dE5f at error correction Q, without the blank margin. Static Wi-Fi, vCard or long URL codes hold more data and need to be larger. Check yours with the print size calculator and the scan checker.
Placement tips
- Dust and rain cover codes quickly. Use outdoor-grade vinyl with a laminate and wipe the site board during weekly checks.
- Hoarding codes for passers-by across the road need to be about a metre wide; if that's too big, put a smaller code at pavement level on the hoarding itself.
- Use error correction H on equipment tags that get scratched.
- Gloves and high-vis don't stop scanning, but direct sun on glossy signs does. Prefer matte finishes.
Call-to-action copy
A code with a reason to scan beside it gets more scans than a bare code. Lines to print next to yours:
- Scan before entering site: induction and sign-in
- Current risk assessment
- Inspect this ladder
- Homes coming soon: scan for prices
QR codes for construction: FAQ
Can a QR code replace printed safety documents on site?
It can give everyone access to the current version, which paper often isn't. Check your local health and safety rules; some documents may still need to be displayed or signed on paper.
How do I make sure the code opens the latest drawing?
Put a dynamic code on the board that opens a hosted PDF page, and upload each new revision there. The code stays the same and nobody opens a superseded drawing by accident.
Will QR codes survive outdoors on site?
The code never expires, but the print can wear. Use UV-resistant outdoor vinyl or engraved tags, error correction H for tags, and check them during regular inspections.
