The inspection of structures such as bridges, towers or roofs is often much easier and more cost-efficient from the air than with conventional methods such as abseiling techniques. Professional sensor systems can be affixed to drones, with the aid of which even the smallest cracks, heat leakages and other damage are found. The experienced and well trained pilots at SPECTAIR assist you with structure analyses and inspections.



The inspection of structures is often a time-consuming and difficult task. The regular examination of structures for damage caused by the ageing process is definitely worthwhile to both preserve the value of real estate, historical buildings and monuments as well as to ensure the safety and functionality of bridges and structures. Building constructions such as bridges or towers, in particular, which often have damage in hard-to-reach places, can only be painstakingly inspected using conventional methods such abseiling techniques, lifting trucks or scaffolding. The consequence: As access to these structures must be restricted for a long time, this leads to disruption for pedestrians and car drivers, and the costs for the inspection soar.


Simple and efficient structure analyses using drones

Drones are the cost-saving and professional solution for inspections and maintenance tasks, which make structure analyses easier and more efficient. With cameras installed on drones, which have a resolution of up to 45 megapixels, bridges, roofs, facades and other structures can be examined with considerable ease and in a shorter time for damage caused by ageing, erosion damage, corrosion and other damaged spots. Cracks in the masonry, deposits, adhesions, spalling of concrete, damaged joints, split concrete, cracked tiles or damage to seals are clearly visible from the air. Damage can be analysed and documented with the high-resolution aerial photographs created by the drones.


Investigation of damage to bridges, roofs, towers from the air

Technical structures such as bridges, chimneys, towers, roofs or damming structures can be examined for possible damage during the surveillance flights with drones – during operation and without any risk to persons who find themselves in the vicinity of the inspection.

The pilots at SPECTAIR equip the drones with a suitable camera and control the aircraft safely along the structures. Even inaccessible and poorly visible places can be reached and carefully examined with drones. Safety and liability risks can thus be reduced for the owner and the operator. This stops damage from progressing and lowers maintenance costs. Inspections with drones can complement the so-called non-destructive testing according to DIN 1076 in a meaningful way and can also replace this in most instances.


The regular inspection of structures for damage caused by the ageing process is definitely worthwhile to preserve the value of real estate, historical buildings, bridges, structures and monuments in the long-term. Facades, roofs and technical superstructures can undergo a detailed check for damage with the help of drones and high-resolution cameras. Poor workmanship or warranty claims can thus be identified at an early stage. Drones are therefore, ideally suited to carrying out maintenance work, building inspections/inspections of structures.




Damage to solar panels, insulation or lines can often not be seen with the naked eye. Thermography using drones detects thermal bridges, leaks and structural defects in a reliable manner. For example, a building’s insulation can be inspected with thermal imaging cameras affixed to the drones. Even thermal losses on roofs and other parts of buildings can be visualised with thermography. After the aerial survey with a drone, the experts at SPECTAIR evaluate the thermographic images. Damage documentation can be created with the help of thermographic reports. Future maintenance tasks and any necessary repairs can be derived from these.
