Safety
Safety goes beyond the STO Building Group (STOBG) family. Exceeding industry best practices, the STOBG Safety 360° program reaches the very heart of how we build safely and is integrated in everything we do. But Safety 360° doesn’t stop here. We purposefully share our innovation with the wider construction industry—to prevent injuries and save lives.
Our Safety 360° Approach
Our approach to safety culture in construction is different; for us, safety is a commitment and a passion, not an obligation. This philosophy embraces encouraging behavioral change and taking a 360-degree view of safety on the job and in our personal lives. The program engages everyone involved as a safety champion, keeping safety at the forefront—for everybody, everywhere, every day.

Safety Culture Image
Safety Culture
Upon joining STO Building Group (STOBG), new staff attend Safety 360° training to learn about our safety culture of care and engagement. We also work with our clients to make sure they understand and play a role in this culture of safety. Our strong Safety 360° culture—which includes sharing email reminders, safety moments, safety stories, and lessons learned—resolutely supports our efforts to protect our staff, our workers, and the public.
Pre-Task Planning Resources
The Pre-Task Planning (PTP) process is important for ensuring employees and subcontractors take ownership of safety goals.

Safety 360° Philosophy
Awareness
The program fosters a 360-degree view of safety, physically and philosophically. We expect active engagement from all employees in their immediate environment, as well as awareness of what’s happening above, below, and next to them. It also means that we look out for one another’s physical and mental safety, speak up about potential safety issues, and are as invested in safety as our safety staff.
STO 250228 Sitework Layton 2025 N41 Medium
Behavior
Behavior is the primary contributing cause of over 80% of accidents. With that in mind, the primary goal of our Safety 360° approach is to avoid risky behaviors altogether. Through behavior-based safety “coaching,” we are helping staff take a more active role in supporting a strong safety culture that solicits feedback, engages the workforce, and empowers people to make a difference.
Safety 360 Behavior
Positivity
Safety 360° relies on positive reinforcement to inspire project teams and employees at all levels to achieve the highest level of safety. Company leaders set the example by discussing safety with their teams on a regular basis, walking through project sites, holding principals’ meetings with subcontractors, and hosting five-worker lunches. The program also recognizes projects, teams, and individuals for exemplary safety performance. Regular feedback, engagement, and coaching are at the program’s core and drive STOBG’s efforts to foster a lasting and positive safety culture across the organization.
Safety 360 Positivity
Shared Responsibility
Each and every employee receives annual safety coaching. We believe that the best way to increase accountability is to increase responsibility, so our superintendents, project managers, and others are as engaged in safety as our dedicated Safety Department team members.
