Machine control solutions for automated construction

Built on decades of innovation, Trimble machine and grade control systems help to improve accuracy, productivity, safety and quality on the jobsite. Gain precision and efficiency across every phase of your project.

What is machine control, and how does it work?

Machine control systems combine positioning sensors with computer displays to give operators better insight into and control over their work. Use cases include:

Enable operators to accurately position buckets, blades and other implements while eliminating the need for surveying, staking and constantly checking work in progress.
Utilize labor and equipment efficiently to reduce costs and minimize wear-and-tear.
Improve connectivity between teams and disciplines by sharing model data and information on work performed.

Machine control systems are growing increasingly autonomous, and the next generations will likely include innovations like artificial intelligence, machine learning and 5G.

Benefits

Machine control: The benefits & why it matters

The machine control we know today is the result of numerous technological advances, particularly in positioning and automation. Trimble, along with innovators in agriculture, geospatial, heavy equipment and academia, played an important role in driving those innovations forward.

These advancements deliver unmatched accuracy and precision through automation and real-time feedback from the field. By eliminating errors, contractors achieve significant cost and productivity gains while virtually ensuring reduced rework on every site.

Precision

Advancements in RTK and GPS technologies allow for centimeter-level accuracy.

Ease of use

User-friendly interfaces enable operators to adapt to machine control quickly.

GPS grade control in civil construction and earthmoving

Trimble machine control helps to maximize project budgets by reducing errors, improving data collection and reducing operator guesswork.

Testimonial

Hear from our customers

We have always imagined a scenario where all of the machines on the jobsite talk to each other in real-time, and that crews could receive real feedback about their work.

Frequently asked questions about machine control and precision grading

What is a machine control system?

A machine control system uses GPS and sensors to guide heavy equipment. It automates blade or bucket positioning to improve accuracy and productivity.

What is the difference between machine control and grade control?

Machine control automates equipment movement via GPS, while grade control specifically ensures the surface meets precise design elevations and slopes.

What’s the difference between 2D and 3D machine control systems?

2D systems use lasers or sensors to manage height and slope on a single plane. 3D systems add GNSS/GPS to track the exact position on a 3D site model.

Key differences:

2D: Uses local references (lasers, stringlines) for simple slopes.
3D: Uses digital designs and GPS for complex contours and site-wide accuracy.

How accurate are GNSS machine control solutions?

GNSS solutions provide centimeter-level accuracy (typically 1–3 cm). Precision depends on satellite signal, correction sources and local site conditions.

Can machine control reduce rework and costs?

Yes. By providing real-time guidance to the design, machine control ensures accuracy on the first pass, cutting fuel use, labor and expensive rework.

Which equipment can use machine control systems?

Machine control supports excavators, dozers, motor graders, pavers, compactors, scrapers and drilling rigs for diverse site applications.

Supported machinery types:

Earthmoving: dozers, excavators, scrapers
Grading: motor graders, compact track loaders
Paving: asphalt pavers, cold planers, slipform pavers
Compaction: soil and asphalt compactors
Specialty: drilling, piling, and marine construction vessels
