Albeit industry efforts, over 1 million underground utilities are annually hit around the world, with estimated damages exceeding $100 billion, not considering billions invested in technologies and inefficient processes aimed to protect utilities during earthworks operations. Available utility data is usually unreliable, and even if data is accurate, the excavator operator may still damage a utility.
Gyroscopic mapping of underground ducts and pipes has been around for a few decades now, and it continues to gain traction amongst the worlds' utilities as an accurate and unique technology. Nevertheless, the market perception until now is that Gyro-mapping, as it's also often referred to, is more expensive than traditional mapping and locating technologies. And although that perception is true, it is not due to the cost of the technology, but rather...

In Singapore, almost all utilities are buried underground to free up valuable above ground space for more liveable environment. These underground assets which consist of power cables, telecommunication lines, water pipes, gas pipes and wastewater networks are critical infrastructure that keep our city functioning. Most cities have not been able to keep reliable, complete, and up-to-date maps of their underground utilities due t...
Synopsis: The UK National Underground Asset Register has gone through rigorous pilot and preparation phases and has learned a lot about the data which we will share for 3 regions before a national roll out. However, despite all the best laid plans there will always be exceptions and unexpected scenarios which will need to either be fitted into the data model or have the data model change in order to fit them. The way in which we make these changes could make or break a project like this wh...
NYU and GISMO's Unification for Underground Resilience Measures (UNUM) is a multi-faceted research initiative aiming to improve our understanding of the city's underground infrastructure assets from the community level through city government and private asset holders. The many activities within the scope of this project include: community collaboration on developing a digital twin of their neighborhood, use of open data to develop an integrated application ...
As one of the oldest American cities, Boston holds a rich history and culture that runs not only through the streets but also beneath them. Many of the large underground infrastructure projects completed between the late 1890s and the late 1920s in Boston are still in use today. The preservation of infrastructure and the insights gleaned from the practices used to create it provide valuable lessons in how to maintain standards of excellen...
We live in a world where the skill required to interpret maps and engineering drawings is decreasing while the density of underground networks is increasing. The result is increased collateral damage, network outages and poor health & safety outcomes for our field workers.Today, we need better ways to accurately capture and comprehend the location and nature of those networks that are out of site under our feet. AR (Augmented...
Leading construction companies are finding a new software as a service component that enables them to view their virtual sites, saving them time and money. This technology breakthrough enabled pioneer construction companies serving clients in multiple industries (colleges, hospitals, residential compounds, malls) to use a new way of representing information about their buildings and utilities, above ground and underground. Benefits include avoiding planning mista...
Due to aging and lack of accurate utility location information, there is significant underground congestion and conflict. This results in increased operational risk especially at waterway, transportation, and utility crossings. The IMU Mapping methods are able to mitigate these risks by providing accurate digital as-built positional data at trenchless crossings, constructed via HDD methods. Unlike other technology mapping solutions, which rely on sending signals below ground, in-line IMU M...

GIS platforms are typically populated with XYZ coordinates with a point spacing of 1 meter or more. in fact, most traditional land surveying techniques, like GPS, often have a point spacing of 3 meters or more, and that is understandable given the procedure to obtain these points. But have you ever wondered what amount of detail is lost when increasing the point frequency? Well, in this seminar, Otto Ballintijn will demonstrate the impact point frequency has on pipe detail usin...
Reveal is building the world's most advanced and accurate digital twin technology for subsurface infrastructure. We're driving a safer, more efficient and sustainable world by revealing the truth of the underground. Join us for a 30min presentation where we will be showcasing our technology through our flagship project in Wellington, New Zealand.
