Inspections with and without drones
Inspections are performed to assess the condition of buildings, installations, or infrastructure. Depending on the situation, this can be done via traditional methods or with the help of drones. In this article, we compare both approaches and explain which method is most suitable for each situation.
What do we mean by inspections?
An inspection is the visual or technical check of a construction, installation, or environment. This can involve detecting damage, wear, deviations, or safety risks. Inspections are carried out in various sectors such as construction, industry, energy, and infrastructure.
Traditional inspections without drones
In traditional inspections, the inspector is physically brought to the location to be checked. This can be done via ladders, scaffolding, aerial work platforms, or rope access techniques.
Advantages
- Direct physical assessment
- Suitable for small, accessible zones
- Possibility for manual measurements or sampling
Disadvantages
- Increased safety risks
- Often time-consuming
- Higher costs due to equipment and site preparation
- Not always possible for hard-to-reach locations
Inspections with drones
With drone inspections, images and data are collected remotely using drones equipped with cameras or sensors, such as with thermography. This allows an inspection to take place without physical access to the location.
Advantages
- Increased safety
- Fast execution
- Inspection possible at great heights or in confined spaces
- Less site disruption
- Detailed visual documentation
Disadvantages
- Not suitable for every situation
- Limitations with very small details or internal structures
- Sometimes additional inspection required
When do you choose inspections with drones?
Inspections with drones are particularly suitable when:
- the location is difficult or dangerous to access
- inspections at height are required
- installations must remain in operation
- a quick visual check is sufficient
- repeatable inspections are required
When is a traditional inspection better?
A traditional inspection remains recommended when:
- physical contact is necessary
- detailed measurements are required
- inspection takes place in small, enclosed spaces
- regulations require physical presence
Combination of inspection methods
In many cases, a combination of traditional inspections and drone inspections provides the best results. A drone can provide an initial overview, followed by targeted manual checks where necessary.
