Shannon Valley is revolutionizing soil stabilization with streamlined data access

The problem: Time-consuming data capture with limited access

Before Trimble Stratus, Maciej found himself wondering how long his knees would survive his surveying work. Each week, he’d set up a GPS total station and walk a worksite, traversing dozens of kilometers to collect survey data by hand.

Examples of some of the downsides of this process include:

• Long processing timelines: After surveying on foot, it took another day or two to process the data licensed computer. All told, the average groundwork survey took about a week from start to finish.
• Wide margin of error: This labor-intensive workflow also cost the team accuracy. Because work couldn’t stop for surveys, lots of material would move before surveyors got from one end of the site to the other, yielding a few thousand cubic meters of error each time.
• Cumbersome data storage: Sharing survey data and orthophotos took longer than it should have—partly due to large file sizes, and partly because locating the right survey data took about 10-15 minutes each time. Those inefficiencies stacked up over the course of a day, leaving Maciej to spend hours each week searching for data.

“Before, we didn’t have a proper application to share this kind of data. The files were too big and you could never just take a quick look. All that data is available at a glance in Trimble Stratus.” – Maciej Masiuk, Site Engineer

The solution: Streamlined processing and data sharing in the cloud

Originally, Shannon Valley sought out Trimble Stratus to help democratize access to survey data. They wanted a way to share their survey results with everyone on the team, regardless of technical background. 

After the rollout, even the initially-skeptical Maciej was won over by Trimble Stratus’s ease of use and consistent accuracy. 

Shannon Valley’s favorite features and workflows:

• Survey-grade accuracy: The magic is in keeping your data consistent over time so you can accurately track your work. He’s found this magic in Trimble Stratus. “If I use good ground control, the data is very consistent. I rely a lot on it,” Maciej said.
• Quick survey timelines: Where traditional surveys might take two or three engineers at least a full day of work—plus another day for data processing—Maciej can now survey a worksite and upload data within 30 minutes. The data is processed while he sleeps and ready to use the next morning. The team uses this streamlined process to regularly survey ecological projects in Ireland that change too quickly for traditional surveys to keep up.
• Direct data access: Everyone on the team now has access to survey data they can easily read and understand. With a browser-based way to share surveys and orthophotos, Maciej saves hours each week on finding and sharing data alone.

“Survey maps finally look like reality, not just lines and symbols that only a few people can read. Even working in the industry for 10 years, you sometimes have to Google what symbols mean. With Trimble Stratus, anyone can easily read the map.” – Maciej Masiuk, Site Engineer

• Volume management: Shannon Valley does innovative work in soil stabilization, recycling soil on-site rather than moving it to a landfill. By screening and processing subsoil waste, they stabilize the soil while reducing fuel burn thanks to an 80% reduction in aggregate movement. This process relies heavily on volume management; the team needs to know exactly how much material is on-site and how much is required to complete a project. With Trimble Stratus, Maciej can fly a site before work ever begins to determine stockpile size and required material volumes.
• Design verification: Maciej also likes the ability to verify design accuracy against 3D site models before the team ever sets foot in the field. “Rather than assuming the design is right, we can drop it in Trimble Stratus and do a quick check to see how it matches with existing ground conditions,” he told us.
• Timeline: Before Trimble Stratus, Maciej had to manually sift through surveys to answer questions about when and where different stages of work happened on-site. This process involved disparate data sets and large files that were slow to open. “If you survey every week, the exact date of what you’re looking for gets blurry,” Maciej said. Now, he uses the Timeline tool to quickly scan backward and forward in time with a simple slider. 

The result

• Easy for non-engineers: Maciej has been pleasantly surprised by the amount of work the team can complete within Trimble Stratus.  “You don’t need a NASA computer to work with your data,” he said.
• Better communication: Trimble Stratus simplifies and clarifies on-site communication. While field workers spend every day on-site and are familiar with its rapid changes, keeping up isn’t always as easy for those in the office. With everyone looking at the same map, clarifying requests is easy, reducing rework.

“If someone asks me to survey somewhere, there’s no miscommunication. I can just pull up the map and say, ‘Show me where you want me to go.’” – Maciej Masiuk, Site Engineer

• Quick site checks: Without the need to set up surveying equipment and walk a site to answer questions about measurements, Maciej can pull up a 3D model from anywhere and conduct quick site checks in less than a minute. 

Overall, Maciej considers easy access to data the biggest win from using Trimble Stratus—especially for those new to drone surveying. “If you don’t have much experience, Trimble Stratus will definitely help you achieve high-quality data,” he said.
