The intelligent site

Gary Ng, CEO and Co-Founder of viAct, considers how Computer Vision is moving worksite safety from compliance to command.

With an unprecedented construction boom taking place throughout the Middle East, there has never been such rapid progression towards mega-infrastructure development, and Saudi Vision 2030 is an example of this growth that has created continual expansion across both the urban and industrial landscapes of the UAE. Many of the newly constructed buildings are considered to be among the most advanced buildings ever built in all respects, including prefabrication, logistics, BIM (Building Information Modelling) and drone surveying technology.

Unfortunately, the safety methods used today to manage injury prevention on construction sites in the Middle East have not changed very much since they were first introduced. Even today, they usually rely on people watching over each other, conducting periodic safety audits, and reacting to incidents after they occur. Therefore, with trillions of dollars being spent on projects for the future in the Middle East, these traditional methods of managing construction worker safety leave a huge gap in the effectiveness of managing incidents on site. However, it is clear that computer vision has started to change the current ways of construction worker safety management, and its implications reach well beyond the safety function.

The compliance ceiling

All EHS professionals are aware with the compliance framework: Establish standards, train workers, inspect activities and document results. This is a good model indeed and had been used for many decades. However, the issue with it is that it was designed for a different scale of operations than the current conditions.

On a mega-site with thousands of workers in multiple work zones, no inspection regime can provide continuous visibility. For instance, a toolbox talk at 7 AM does not prevent a PPE non-compliance by a worker at 2 PM when the temperature is 45 degrees. Similarly, a manual permit-to-work does not provide real-time information about an unauthorised entry into the operating radius of a crane.

The data reflects this. The current global mortality rate within the construction industry is about 6.1 per 100,000 workers. This is nearly double the all-industry average. Across the GCC, despite regulatory reforms, incident rates in the region have historically lagged behind more mature safety markets. The existing compliance model produces documentation, but it rarely produces prevention.

From monitoring to prediction

The transformation that computer vision enables is not a mere small adjustment. It is a change in how recording is done from observations after-the-fact to instead include information that describes the conditions that precede an incident.

Think about a worker approaching a restricted area near active lifting operations. The traditional method of recording would be a camera recording the worker entering this area. But a well-built scenario-based AI will notify the supervisor of the worker’s approach and create a response plan (site-wide response) before they enter the area. The difference isn’t just the camera; it is the way the video feed is processed through the AI system.

A wide array of site risk scenarios exhibits this same reasoning: fatigue postures for lone workers, PPE non-compliance before entering a high voltage area, proximity violations between individuals and mobile equipment, and environmental stress indicators that show the potential for a heat-related injury. In all of these scenarios, the AI-powered safety system does not react after-the-fact to instances of injury. The system reads the conditions that created an injury, and ‘intervenes’ in the interval of time between the two points, that is, the point at which the event started and the point at which one can react to it.

Operationally, this is what ‘predictive safety’ is. It is not simply a marketing position; it represents a change in the informational architecture used to manage sites. The goal was never to create a smarter camera to provide the site leadership with a different way to manage their assets and people. The true goal was to provide them the information needed to make ‘real-time’ decisions concerning the potential for a future accident. This is the only ‘safety’ that actually works.

The intelligence in action

Deploying computer vision across a mega-project site in the Gulf is an operational layer that serves multiple risk functions simultaneously. For example, at any point during a given shift, that same computer vision system can be used to track vehicle movement patterns to prevent blind-spot collisions near active excavation zones; detect improper scaffolding assembly before a crew begins working at height; monitor material stacking to flag structural instability risks in storage areas; and identify unauthorised personnel approaching site perimeters during off-hours.

The value of deploying computer vision is not about the individual functions but rather relating that information into a single, unified command picture that executive leadership on-site can act on in real-time.

This is where the transition from monitoring to command becomes tangible. A safety officer who manages a dashboard that reflects live risk conditions for the entirety of 500-acres sites has a fundamentally different capability than an individual who only receives incident reports. Decisions concerning shift rotation, zone access and equipment scheduling can be made based on live intelligence instead of historical trends. Safety is no longer separated from site operations, but rather directly impacts the day-to-day operational flow of the site.

The results of one such implementation shows this trend to be true. A major construction project in Saudi Arabia, integrated IoT-enabled smart wearables and AI video analytics to help manage heat stress of workforce working under extreme desert conditions, dispersed over an extensive geographical area. The system allowed continuous physiological monitoring rather than periodic wellness checks, so risks could be identified before workers showed any symptoms. This allowed supervisors to intervene immediately and led to a 63% reduction of on-site medical emergencies. Further, the data collected facilitated operational planning and risk reporting for management.

Safety as strategy

The Middle East is currently experiencing a unique opportunity with all the developmental activities happening at the same time as the political will behind Vision 2030. Further, many national strategies are being implemented across the GCC. Any infrastructure decisions made today will create the operational standards for decades to come going forwards. Embedding predictive AI oversight into the current infrastructure now, instead of retrofitting it later, is both cost-effective and oriented towards long-term strategic goals.

C-Suite leaders should no longer wonder ‘Will AI enhance safety?’, as the current deployment of AI has already answered the question. What they should instead wonder is: ‘How will they utilise their safety data?’ Will they be treating safety data as an operational asset, or will they simply continue to manage it as a compliance obligation. The sites that successfully answer this question will benefit from reduced incidents and, most likely, gain a measurable competitive advantage compared to sites that do not.
