Smart Construction 3D Machine Guidance

Komatsu’s Smart Construction 3D Machine Guidance is an easy and affordable way to bring machine guidance technology to any of your standard excavators to improve grading performance and efficiency over the standard machine and/or traditional stake-plus-grade-checker method. By bridging the technology gap, operators now have access to 3D design and topography data to help drive grading accuracy and productivity. With the optional payload monitoring system, the operator has access to payload data which assists them in accurately loading trucks based on its rated payload.
No longer is a GNSS equipped dozer or grade checker needed to keep the excavator on grade; accurate 3D GNSS technology gives the operator all the needed design and position information needed to free up other assets. Digging below grade is wasted production. Minimize over-excavation and leave a smooth surface with a high accuracy guidance system that assists operators from digging below target grade. Avoid major DOT fines from overloaded trucks and provide the operator data regarding how much material has been moved.

Product highlights and benefits

Accuracy with ease though global connection
Accuracy with ease though global connection

No more setting up a laser, grade stakes or bench every time the machine moves. With global navigation satellite system (GNSS), a machine can determine where it is on the job site and what the target grade is to help improve efficiency and drive time savings. 

Economical and powerful
Economical and powerful

Lower the startup costs of bringing technology to your standard excavator — for new and legacy excavators — with compact and modular kits that are professionally-installed and fit most make + models.

Critical insight on demand

Smart Construction 3D Machine Guidance collects as-built data that can be used for reports to customers and data-driven plans. With seamless integration with Smart Construction Dashboard, monitor machine production and job site progress from the office. 

More data, less effort
More data, less effort

No longer is a GNSS equipped dozer or grade checker needed to keep the excavator on grade; accurate 3D GNSS technology gives the operator all the needed design & position information, so fewer people need to be working on the ground or in the open trench.

With the equipped payload monitoring system, avoid major DOT fines from overloaded trucks and the operator has better data about how much material has been moved.

Return on investment


Slope shape final

42% Faster production


Flat surface final

32% Faster production

These return on investment calculations are based on a case study performed by Earth brain Japan . Conditions for both sloped and flat surface studies were independent. The sloped surface study compared two Komatsu PC350LC-8MO excavators, one with 3DMG installed, and one without. The flat surface study compared these two machines, as well as third comparable excavator operating without 3DMG. The machines were operated with identical conditions, and the rate of area graded per hour was calculated.

"Smart Construction 3D Machine Guidance gave me more control over what I was doing, and that is great if I need to overcut, undercut, or dig outside the perimeters of the model. It allows you to cut a guy out, so you can can cut your labor in half. Since you aren't guessing while operating and don't have to wait on someone, you can be more accurate and operate faster. You're going to save at least half your time"

-Justin Raper, Sons Construction
