How KRS Strengthened Safety Standards and Transparency in Construction with Worksober
In a work environment characterized by constant movement and changing locations, KRS needed a flexible yet reliable solution for sobriety control. Before adopting Worksober, the company faced challenges with manual testing — physical breath checks required extra personnel traveling between sites, which was inefficient and inconsistent.
The decision to implement Worksober was driven by its ability to:
- Automate the sobriety testing process and eliminate the need for additional staff;
- Provide real-time data access for immediate decision-making;
- Ensure transparency and objectivity across all projects;
- Monitor both employees and subcontractors under the same standard.
Since 2021, KRS has installed stationary Worksober devices in key locations across its projects. The system operates fully automatically — employees are tested in the morning, during lunch, or after work. Devices are strategically positioned at site entry points, making testing a natural part of the daily routine. Because employees know the system records exact times and results, any attempt to bypass procedures has been effectively eliminated.
The system also includes subcontractor testing, giving managers visibility into both internal and external workforce compliance. Worksober uses a contactless testing method — no mouthpieces, lower maintenance costs, and easier daily operation. All data is available remotely through the Worksober management dashboard, ensuring full accessibility for decision-makers.
With Worksober, KRS achieved measurable improvements in both safety and process efficiency:
- Improved discipline and accountability – consistent, automated testing promotes responsible behavior.
- Transparent subcontractor oversight – incidents of non-compliance among partners are clearly recorded.
- Reduced administrative workload – sobriety testing no longer requires additional staff or manual coordination.
- Faster incident response – automated alerts notify managers instantly, preventing intoxicated individuals from entering the site.
- Increased transparency – centralized data provides a clear overview of all sites in real time.
The KRS experience demonstrates that even in complex, multi-site construction operations, preventive systems like Worksober can deliver tangible benefits — from stronger safety culture to reduced administrative pressure. By digitizing and automating sobriety control, the company reinforced its professional standards and built a culture of accountability across all levels.
“Worksober – a partner for safer construction sites. That says it all.”
