Protecting sub-sea level New Orleans from flooding. Reviving gold mines mothballed decades ago. These are just some of the challenges that engineers are successfully taking on around the world with help from Bentley Systems software. Learn more in the stories below about how engineers are integrating digital twins, artificial intelligence (AI), and other technology to solve major infrastructure challenges and build for the future.
A Digital Gold Rush
Record gold prices have flipped the script on the economics of mining, which means mines that were closed decades ago are suddenly gleaming again with promise. But reviving a mine isn’t as simple as turning the lights back on. Companies need to know how much gold is left, where to find it, and how much it will cost to get it out. They also need to determine the mine’s impact on the environment—which is where Seequent, Bentley’s subsurface company, and its industry-leading software come in. Mining teams are turning to Seequent’s Evo, a cloud platform that connects data, teams, and tools in a single collaborative environment. Evo’s accurate modeling isn’t just good for the bottom line—it’s essential for sustainability. “If you can move less rock for more gold, it’s not only cheaper, it’s less environmentally damaging,” says Seequent geologist David Newton.
Protecting The Big Easy
Revelers whooping it up at New Orleans’ famous Mardi Gras celebration may not know that the city is not only surrounded by water, but that the streets hosting the boisterous parades are near or below sea level. Keeping everyone dry (from floodwater, at least) is a marvel of U.S. infrastructure. A key component of the system is the giant 17th Canal Pump Station. One of the world’s largest pump stations, it takes water from a critical canal that drains New Orleans and dumps the water into Lake Pontchartrain, just north of the city. The station’s pumps are so powerful that they can drain an Olympic-size swimming pool in just a few seconds.
The station now has a digital twin, built using software developed by Bentley. Joey Coco, president and CEO of a Louisiana engineering firm involved in the project, says the pump station is just the start. He says many more pieces of infrastructure along the Mississippi River, which runs through New Orleans, could be digitized in the future, a prospect that would help engineers build, maintain, and operate flooding safeguards—and help them make faster decisions.
A 19th Century Tunnel Meets 21st Century Tech
Some 150 years ago, Victorian engineers completed one of Britain’s most audacious engineering projects: the Severn Tunnel, connecting the west of England to south Wales. Thanks to its famously damp and dark interior, the tunnel has long been difficult to inspect, maintain, or even visualize. Plus, maintenance is costly because it requires shutting down the busy rail line. But with the help of Bentley’s cutting-edge technology, this historic tunnel now has a digital twin: a 3D digital replica hosted in the cloud. Built in Bentley’s ProjectWise software, the digital model allows engineers to explore and analyze the tunnel without stepping inside.
Notes From the Underground
The world’s largest geothermal field has been powering homes and businesses in northern California for more than 60 years. Power plants in the Geysers region tap into the heat generated by the Earth’s interior, harnessing steam from deep underground wells and converting it into electricity. Geothermal energy isn’t just renewable—it’s also reliable, unlike weather-dependent sources like solar and wind that generate intermittent power.
Bentley is helping the Geysers plants go full steam ahead into the future. Plant operator Calpine partnered with Seequent, Bentley’s subsurface company, to create a 3D model of the underground steam reservoir. The modeling helps Calpine optimize geothermal energy production, efficiently plan new wells, and visualize how the reservoir will respond to changes.
Dublin Fire Brigade Blazes a Trail for Digital Twins in Emergency Response
Gathering data at the Dublin Fire Brigade has come a long way since Dennis Keeley joined in the 1980s. Back then, paper records of emergency calls were impaled on a 6-inch nail. These days, Keeley is Dublin’s fire chief and leading a digital twin project, using Bentley’s iTwin platform, that promises to make the city’s emergency response safer, smarter, and faster.
Digital Twin for Emergency Response is a cloud-based virtual model of Dublin’s urban landscape. The model brings together data, from building layouts to fire hydrant locations into one easy-to-use interface. With critical information instantly available to firefighters, the system promises to save critical time and enhance safety for both firefighters and the communities they serve.
