Solution Summary: Geospatial Augmented Reality System
An augmented reality (AR) mobile technology application (app) for smart phones or tablets that can locate underground cables to prevent electrical hazards and consequently ensure a safer earthwork process.
Risks Addressed:
Electrical hazards are among the main construction industry hazards that cause serious injuries and death. The Bureau of Labor Statistics reported the number of fatalities in electricians increased by 14 cases in 2014 to 78 (BLS 2014). Electricity can cause electric burns, electrocution, shock, arc flash/blast, fire, and explosions. Electrical hazards may happen due to failure to detect the accurate location of cables before construction site excavation, jack hammering, well drilling, landscaping, trenching for piping and fence installation – all of which can lead to accidental contact with power cables, resulting in electrocution, shock or burns (Figure 5). The annual cost of accidents due to hitting utilities during the excavation process is estimated to be more than a billion U.S. dollars (Spurgin et al. 2009). Excavation-related accidents account for nearly one-third of all incidents related to utilities (Talmaki et al. 2010). Thus, paying attention to underground cable location technologies can make for more accurate and safer excavation processes. The risk of working near cables must be assessed and controlled.

How Risks are Reduced:
Hitting utility lines can create physical danger to construction workers, interruptions to the daily lives of people who depend on the utility, and danger to nearby buildings. All these lead to excessive costs, not to mention deaths and injuries. Using this new technology will drastically change the way underground cable locations are mapped.
Using this technology helps prevent excavator-underground cable hits and avoids damages to existing underground cables due to unknown or erroneous locations of utilities. This combination of various technologies can give comprehensive information to the excavator about the location, depth and other attributes of underground cables and can alleviate problems that have occurred with previously used approaches. Therefore, using this technology at jobsites can improve safety and accuracy in the excavation process. Moreover, it can clarify the relationship between aboveground structures and underground infrastructure in order to respond to the risk of accidents associated with excavation.
