QR codes provide a number of benefits to construction workers, including:

‍

• Tracking projects and materials through scanning as opposed to manual data entry. 
• Displaying safety regulations and procedures through QR codes that provide immediate access to information.
• Streamlined communication between workers, managers, and supervisors.
• Displaying marketing materials on signs, business cards, and more.

‍

QR in construction are matrix barcodes that can store and share information about a construction project. They provide a quick and convenient way to:

‍

• Store and access detailed information about a project, such as drawings, instructions, and safety protocols. 
• Access information quickly and easily. 
• Reduce paperwork and streamline communication between the site manager, contractors, and the design team. 
• Track inventory, document progress, and ensure compliance with safety regulations.

In the US, there is not currently a mandate on QR codes in construction sites. However, other countries already require them for all workers or visitors on a site. While not required on US construction sites, they may be used to:

‍

• Help ensure safety and compliance. 
• Track attendance and ensure workers are present and accounted for. 
• Track materials and equipment used onsite. 
• Share safety information and provide easy access to it onsite. 
• Track and manage compliance with regulations.
