How Modern GNSS Technology Is Changing Solar Farm Construction
As utility-scale solar farms become larger and more complex, contractors are looking for smarter ways to improve productivity without sacrificing accuracy. One of the biggest shifts in recent years has been the move from traditional survey set-out methods to GPS piling guidance systems.
While survey set-out remains an essential part of construction, GNSS technology is helping piling contractors work faster, reduce delays and minimise costly rework.
At Red Edge Resources, we provide advanced GPS piling and drilling guidance solutions that help renewable energy projects across Australia stay on schedule and on budget.

What Is Traditional Survey Set-Out?
Traditional survey set-out involves a surveyor marking the exact location of every planned pile using GNSS equipment or a total station. These locations are typically identified with pegs, paint or flags before the piling crew arrives on site.
While highly accurate, this process can become time-consuming on projects requiring tens of thousands of pile installations.
Common challenges include:
- Extensive labour requirements
- Delays waiting for survey crews
- Damaged or displaced survey pegs
- Rework when markers are disturbed
- Additional mobilisation across large sites
What Is GPS Piling Guidance?
GPS piling guidance uses high-precision GNSS technology to display pile locations directly to the operator inside the machine.
Rather than relying solely on physical markers, operators can navigate to the planned coordinates using digital engineering files and real-time positioning.
This creates a more streamlined workflow while maintaining excellent installation accuracy.
Comparing the Two Methods
| Traditional Survey Set-Out | GPS Piling Guidance |
|---|---|
| Requires physical pegs or markers | Uses digital coordinates and GNSS positioning |
| Heavy reliance on survey crews | Greater operator independence |
| Pegs can be disturbed or removed | Digital plans remain available on-screen |
| Slower on large projects | Faster navigation between pile locations |
| Higher labour input | Improved machine productivity |
| Repeated survey visits often required | Reduced survey dependency |
Advantages of GPS Piling Systems
Faster Installation
Operators can move directly from one pile location to the next without waiting for additional survey marking, increasing daily production rates.
Improved Productivity
Digital navigation reduces downtime and keeps piling equipment working efficiently throughout the project.
Reduced Survey Costs
Survey teams can focus on establishing site control and quality assurance instead of physically marking every individual pile.
Better Accuracy
High-precision GNSS guidance helps ensure piles are installed according to engineering design, reducing alignment issues during racking installation.
Simplified Large-Scale Projects
For solar farms covering hundreds of hectares, digital guidance makes it easier to manage thousands of installation points consistently.
Is Traditional Survey Set-Out Still Important?
Absolutely.
Survey professionals remain essential for:
- Establishing site control
- Verifying project coordinates
- Quality assurance
- As-built verification
- Engineering compliance
In practice, many of the most efficient projects combine professional survey control with GPS piling guidance to achieve the best balance of speed and precision.
Why Australia’s Solar Industry Is Embracing GNSS
The rapid growth of renewable energy construction has increased demand for technologies that improve efficiency without compromising quality.
GPS piling systems help contractors:
- Complete projects faster
- Reduce labour-intensive workflows
- Minimise rework
- Improve consistency
- Better integrate with digital engineering models
As projects become larger, these productivity gains become increasingly valuable.
