Trimble-Powered Accuracy for Every Project in Duluth & Northern Minnesota
At Great Lakes Excavating, we invest in state-of-the-art Trimble GPS technology because precision isn't optional—it's the foundation of quality work. With 25+ years serving Duluth and Northern Minnesota, we've seen how the right technology transforms projects.
Our Trimble Earthworks system converts your engineering plans into digital models that guide our equipment with millimeter precision. This isn't just about accuracy—it's about getting your project done right the first time.
Industry-Leading Technology for Unmatched Precision
We establish a base station at a static point on your site that communicates with our rovers and machinery. This provides the reference point for all positioning data, ensuring consistent accuracy across your entire project.
Our handheld rover devices allow us to locate and verify survey points with precision. Whether we're shooting building corners or verifying grades, the rover ensures everything sits exactly where it should.
We utilize Virtual Reference Station (VRS) technology—the same system professional surveyors rely on—for real-time corrections that enhance our positioning accuracy to centimeter-level precision.
Our machines run Trimble Earthworks software that converts DWG files and engineering plans into 3D models. Operators see the design in real-time on in-cab displays, enabling precise execution without traditional stakes.
Accuracy You Can Trust
When we shoot the corners of your building, you can trust it's sitting in the correct position. Our GPS technology eliminates guesswork and ensures your project meets specifications from day one.
Site Layout & Modeling
We have all the right tools to perform precise site layout and modeling. From initial staking to final grading, every step is verified against the digital plan.
Cost & Time Savings
GPS precision reduces material waste, minimizes rework, and speeds up project completion. When work is done right the first time, everyone saves money.
Our GPS Technology Excels Across All Project Types
Precise grading for building pads, parking lots, and stormwater systems throughout Duluth.
Accurate foundation layout and lot grading for homes across Northern Minnesota.
Exact trench depths and alignments for water, sewer, and underground utilities.
Precise subgrade preparation and grading for roadways and infrastructure.
Everything You Need To Know About Our GPS Earthwork Services
Our Trimble GPS technology typically achieves accuracy within 0.1 feet or better. For projects requiring even greater precision, we can implement additional measures to achieve centimeter-level accuracy using our VRS integration.
Yes. Our Trimble Earthworks system converts DWG files directly into 3D models that our equipment uses in the field. This seamless integration ensures your engineering plans are executed exactly as designed.
GPS precision reduces material over-excavation, eliminates traditional staking costs, and minimizes rework from errors. Most projects see 20-30% savings compared to conventional methods.
We work alongside surveyors and can integrate their data into our systems. Our GPS technology complements surveying services—we use VRS networks that surveyors rely on for our positioning data.
Our Trimble equipment includes redundant systems and base stations that maintain accuracy even in challenging conditions. Heavy precipitation or dense tree cover can occasionally impact reception, but our equipment is designed for Northern Minnesota's demanding environment.
Any project where precision matters benefits from GPS technology. Complex grading, utility installation, foundation layout, and large-scale developments see the greatest advantages, but even smaller residential projects benefit from the accuracy and efficiency.
