Łęgprzem case study – Automating PPE Compliance Monitoring on Construction Sites

How to use AI video analytics to automatically detect helmets and safety vests on large construction sites, reduce HSE violations by dozens of percent and strengthen compliance evidence for investors and general contractors.

Full client name: Łęgprzem Sp. z o.o.

A general contractor delivering construction projects in environments with strict workplace safety and operational oversight requirements.

Challenges

Ensuring that employees and subcontractors consistently wear required hard hats and high-visibility safety vests on the construction site.

Monitoring a large number of people moving between different work zones, which makes continuous manual safety supervision difficult.

Reducing the risk of delayed response to safety violations, particularly in dynamic and high-activity construction areas.

Documenting PPE violations and maintaining a consistent audit trail for safety teams and operational supervisors.

Addressing the limitations of traditional CCTV monitoring, which requires continuous human observation of camera feeds.

Solution

We combine AI video analytics with the client’s existing CCTV infrastructure to automatically detect missing personal protective equipment, including hard hats and high-visibility safety vests, and support real-time workplace safety monitoring.

Discovery

Identification of critical work zones, workplace safety requirements, common violation scenarios, and camera operating conditions across the construction site.

Requirements & Solution Scoping

Definition of the PPE items to be detected, the monitored zones, and the rules for generating alerts and compliance reports.

Implementation

Configuration of AI video analytics for selected CCTV cameras, activation of hard-hat and safety-vest detection, and adaptation of the system to real construction-site conditions.
