Root risks are often an invisible factor in construction and excavation works. Yet they can cause considerable problems if not identified early on. Read why root damage is such a big risk, what impact it can have on your project and how you can avoid big costs and delays with the right monitoring and data analysis.
1. The scale of the problem
Trees' roots are often closer to pipes, cables and foundations than you might expect. During excavation work, unnoticed damage to these roots can lead to:
- Unstable trees: When the main or stabilising roots are cut, the likelihood of the tree falling over increases significantly.
- Accelerated tree mortality: Damaged roots can let in diseases and fungi, seriously affecting the overall health of a tree.
- Unforeseen costs: Tree damage and resultant liability issues can lead to claims and repair costs well beyond the budget.
2. Risks to safety and infrastructure
Underestimating root risks not only incurs additional costs, but can:
- Putting safety at risk: An unstable tree poses a threat to road users, pedestrians and adjacent buildings.
- Damage to infrastructure: Roots often grow along or under roads, pavements and foundations. If done incorrectly, holes or subsidence can occur.
- Delay in the construction process: If unforeseen problems come to light, work has to be stopped until the situation is resolved, leading to considerable delays.
3. How to prevent root damage?
A careful roadmap is essential to mitigate risks and ensure the continuity of your project.
- Take stock of the environment
Map all trees in the project area. When doing so, pay attention not only to large trees, but also to young plantings. - Leverage technology and data analytics
With advanced solutions, such as TreeRisk from NEO, you can map trees and roots without digging. Thanks to satellite images, lidar scans and other geo-information, you will know exactly what to consider. - Working with tree experts
Consult a tree specialist or landscaper for a thorough inspection. They can assess on the spot which trees are vulnerable and how the roots run. - Establish a clear work schedule
Make sure contractors, project managers and green space managers are aware of the identified risks. Agree how to responsibly address any roots that get in the way. - Monitor continuously
Especially with long-term projects, it is important to monitor the situation regularly. By taking interim measurements and comparing data, you avoid surprises halfway through the project.
4. How geodata helps minimise root risks
Traditionally, the root system is often only imaged during the execution of the work, which significantly increases the risk of damage. Thanks to modern technology, however, you can do this even before the work starts:
- Mapping exact locations of root growth: With satellite analyses and historical vegetation data, among others, you can see where the roots are likely to be.
- Determining the health of trees: Based on multi-year data, you can estimate whether a tree is already weakened, making it more likely to topple when interventions are made in the soil.
- Deploying prediction models: By combining different data sources, you gain insight into how roots are developing and where weaknesses may arise in the future.
5. Avoid delays and cost overruns
When a project is delayed due to unforeseen root damage, the costs can be enormous. Not only does the damage have to be repaired (think replanting trees or repairing infrastructure), but also the entire planning is out of sync. With a structured approach and data-driven decision-making, you avoid unnecessary claims and budget overruns.
6. Conclusion: Invest in upfront, save in output
Root risks are not visible at first, but can have major consequences. By investing early in data analysis, expert inspections and good coordination between stakeholders, you significantly reduce the risk of damage and delay.
