Construction Site Access Control

Site access control refers to the systems used to manage and monitor who enters and exits a construction site.

These can include turnstiles, facial recognition, QR codes, RFID, or PIN codes—often tied to induction status and worker credentials to ensure only authorised personnel gain entry.

Biometric systems (like facial recognition or fingerprint scanning) improve accuracy, reduce the risk of lost or shared credentials, and speed up sign-ins.

They also create reliable, real-time records of worker attendance and help enforce safety and compliance rules at the gate.

Most modern systems are built to recognise workers wearing hard hats or face coverings.

If the face is too obscured (e.g. sunglasses), backup sign-in options like QR codes, RFID badges, or PIN codes ensure smooth access without delays.

Integrated systems can sync with a safety platform, so only inducted and approved workers can access the site.

If a worker’s certification is missing or expired, the system automatically blocks access—helping maintain compliance and site safety.

Access systems typically collect time and attendance data, plus biometric data if facial recognition is used.

When deployed responsibly, these systems encrypt data, limit access, and comply with GDPR and regional privacy laws.

Yes. Each sign-in/out creates a timestamped entry tied to a worker’s profile. This automates labour tracking for payroll, billing, and compliance reporting—and removes the need for manual timesheets.

Absolutely. Systems can scale from large multi-gate projects to smaller sites using QR codes on a tablet or mobile app.

Even without full turnstiles, small teams can benefit from digital records, verification, and real-time tracking.

Yes. Many access control systems integrate with safety software to centralise worker data, inductions, and site access permissions.

For example, HammerTech and Irongate offer a fully integrated platform where inductions, approvals, and access control are all connected.
