How Infes Ensured Systematic Sobriety Control on Construction Sites Without Additional Personnel

Infes is a general contracting company providing construction and project management services since 2013. With over 12 years of experience delivering unique and technically complex projects, the company now manages around 40 active construction sites simultaneously and employs nearly 500 people. Infes values an individual approach to each project, focusing on solutions that are not only effective but also sustainable in the long term.
Why the Company Chose Worksober?

Before implementing Worksober, sobriety checks were conducted using portable breathalyzers. This approach created several practical challenges — site managers struggled to ensure that all employees were tested, and as the company expanded, random testing no longer guaranteed consistent or adequate control.

The decision to choose Worksober was based on several key factors:

  • The ability to automate sobriety checks and minimize the risk of human error.
  • Functionality that allows employee identification and sobriety testing in one system.
  • Integration with the national Sodra system.
  • Flexibility — adaptable to different project sizes and types.
How Worksober Helped?

Since 2021, Infes has installed 43 stationary Worksober devices at construction site entrances. The equipment is integrated with work time tracking and operates independently without supervision. Employees identify themselves using a personal code, take a facial photo, and perform a sobriety test before entering or leaving the site.

The system operates through API integration, allowing real-time data access, centralized information management, and complete elimination of manual administration. This reduced the need for human resources while ensuring transparent and standardized control across all company sites.

Results

The Worksober solution helped Infes achieve several key objectives:

  • Reduced administrative workload for site managers — sobriety checks now run automatically, without additional personnel.
  • Full sobriety control for all employees at every site, regardless of size or location.
  • Unified control practices led to a lower risk of alcohol-related incidents and improved employee discipline.
  • Centralized systems and real-time data access increased transparency and made operations easier to manage.
  • Employees can now focus more on their direct responsibilities, while managers can more easily monitor work hours and attendance.
Summary

Infes demonstrates how modern technology can not only automate control processes but also build greater internal trust within an organization. By implementing the Worksober system, sobriety checks became systematic, transparent, and highly efficient. According to the company, the solution has raised workplace safety standards and significantly reduced the risk of incidents.
