When it comes to building a house, the foundation is the most important part. Any mistake or delay at this stage can throw the entire project off schedule and affect the final quality of the home. In the southern suburbs of Stockholm, Sweden, a construction team was building a three-story villa with an underground garage. To ensure they got the foundation right, they decided to use the FJD G31 PRO 3D Excavator Guidance System.
By using this smart system, the team was able to cut their construction time almost in half. The original plan called for 95 days, but they finished in just 47 days. This boosted their efficiency by an incredible 50%. Even with faster speed, the team didn't have to sacrifice quality. The system helped them maintain high accuracy, avoiding costly mistakes and rework. It's a great example of how FJD machine control technology can help build better homes faster.
Complex Challenges Beneath the Frost Line
The project of building a three-story villa in the southern suburbs of Stockholm faced significant challenges right from the start. The team was tasked with a complex foundation excavation, needing to dig to a depth of 4.5 meters for an underground garage. Adding to the difficulty, the project began in May, a time when the seasonal thawing of permafrost layers made the ground conditions particularly difficult and unpredictable.The soil was soft and sticky, causing the excavator, a Volvo EW100, to constantly deviate from the planned slope. This operator had to make frequent manual corrections, slowing down progress and increasing the risk of errors. To make matters worse, meltwater from the thawing ground quickly filled the foundation pit. This water accumulation made it impossible for the operator to visually check the depth and slope, forcing them to work blind. Without a clear view, the crew was forced to rely on traditional, time-consuming methods.
Under these tough conditions, the project team had to frequently stop work so surveyors could manually check measurements and place stakes. This constant starting and stopping made the work slow and inefficient. As a result, the foundation was originally expected to take a very long time—a full 95 days—to complete. The team knew they needed a better solution to overcome these challenges and keep the project on schedule.
How FJD G31 PRO Transformed the Workflow
By installing the FJD G31 PRO 3D Guidance Systemon their EW100 excavator, the construction team was able to work much faster and with greater accuracy. This smart technology completely changed their work process for the better.
Accurate Digging, Even Underwater
The system proved its worth immediately, especially when water filled the pit. Even when the bottom and slopes were covered by water, the operator could still rely on the real-time display. The screen in the cab showed the bucket's exact location and the correct slope from the digital plan. This allowed the operator to keep digging confidently without needing to see the ground or wait for the water to be removed.
Live Depth and Slope Control
The G31 PRO gave the operator live updates on the depth and slope. The operator always knew exactly how deep and at what angle to dig. This greatly reduced the need for surveyors to do manual checks, so the excavator could keep working and stay perfectly aligned with the plan.
Faster Approvals with Digital Reports
The system automatically saved all the digging data as they worked. When the job was done, it created a digital report right away for the supervisors. This made getting approval much faster and easier because they didn't have to wait for manual checks. This helped the team get the project approved quickly and avoid any delays.
Happy Results: Efficiency and Precision Delivered
The results from using the FJD G31 PRO were truly impressive. The system made the project much faster and more precise. The team cut their timeline from 95 days down to just 47 days—an incredible 50% boost in efficiency.This speed didn't lower the quality, either. The team achieved high accuracy with every movement, getting the slopes and depths right the first time. This meant there was no rework. This saved time and effort while making sure the foundation was built to the highest standard.
The final approval process was also made much simpler. Since the system automatically created digital reports, the team got "first-time pass" approval from the supervisors on their very first try. The customer's feedback said it all: "The FJD G31 system is really amazing, and we can actually see that it works. Without it, we could not have finished such a big project so much faster." This proves that the G31 PRO is a powerful partner in construction, delivering faster and more accurate results.
Smarter Construction for the Future
This project is a perfect example of how the FJD G31 PRO 3D Excavator Guidance System is changing construction. It shows that even with difficult ground and weather, a team can work faster, more precisely, and with more confidence. For building residential projects like this villa, the benefits are clear: shorter timelines, lower costs, and faster acceptance. The system made it possible to dig the foundation in half the time, without sacrificing quality.As more and more construction teams start using smart tools, we will see a new level of efficiency in the housing industry. Intelligent excavation, like that used on this project, will set a new standard for how we build. It proves that using smart construction technology like that from FJDynamics helps teams build smarter, better, and more efficiently.
