Challenges and Results

During the hot summer months this project was completed, safety was a concern. Our project leaders and Safety Supervisors conducted extensive on-site training for workers on mitigating hazards they faced in execution. We created traffic patterns so that vehicles could move safely in tight spaces and dedicated workers to guide drivers to their destinations. Our Safety team also ensured that workers had the proper personal protective equipment and instituted processes to ensure tools and equipment were in good working order. By mitigating safety concerns, we were able to ensure swift and efficient execution on an accelerated schedule.

As a result, we completed the substation build in four months using 30 direct craft workers and roughly 25,000 man-hours. Our team ultimately improved electrical service to businesses and residents throughout the client’s service territory, all without a single recordable injury.
