Case Study: How Computer Vision Solutions Enhanced Safety at a Major Construction Company

Client Profile

Industry: Construction
Size: Large national construction company with 2,500+ employees
Location: Multiple construction sites across North America
Annual Revenue: $850 million

Our client is a well-established construction company specializing in commercial and industrial projects. With dozens of active construction sites and thousands of workers, including both direct employees and subcontractors, they faced significant challenges in maintaining consistent safety standards across all operations. The company has a strong commitment to worker safety but struggled with the limitations of traditional safety monitoring approaches.

The Challenge

Construction remains one of the most dangerous industries, with falls, struck-by incidents, and equipment accidents causing thousands of injuries and fatalities annually. Our client was experiencing several critical safety challenges:

• Inconsistent PPE Compliance: Despite strict policies, ensuring that all workers consistently wore appropriate personal protective equipment (PPE) was difficult to monitor and enforce.
• Unauthorized Site Access: With multiple subcontractors and shifts, unauthorized personnel frequently gained access to construction sites, creating security and liability concerns.
• Equipment-Worker Proximity Risks: Dangerous interactions between heavy machinery and workers were difficult to predict and prevent.
• Manual Safety Inspections: Traditional safety inspections were time-consuming, subjective, and only provided point-in-time snapshots rather than continuous monitoring.
• Delayed Incident Response: Safety incidents often weren't identified until after they occurred, limiting the ability to provide immediate intervention.
• Documentation Challenges: Maintaining comprehensive safety records for compliance and insurance purposes required extensive manual effort.

The Safety Director summarized their situation: "We were committed to creating the safest possible environment for our workers, but our traditional approaches weren't scaling with our growth. We needed a solution that could provide continuous monitoring across all our sites and help us move from reactive to proactive safety management."
