Aerial survey

We offer high precision surveying services with the help of our drones (multicopters). Our UAV / UAS systems offer high accuracy, efficiency and flexibility.


• Photorealistic 3D model representation
• High-resolution photos & 3D point clouds

Applications areas:

• Architecture
• Open-cast mining
• Real estate sector
• Construction industry (civil engineering, building & bridge construction)
• Archeology & Historic preservation
• etc.


For large area- & topographic survey drones offer a perfect foundation for creating high-resolution orthophotos. Accuracies in the low centimeter range are possible.

Applications areas:

• Construction industry
• Design offices
• Architects
• Real estate industry
• Agriculture & forestry
• etc.


Extensive inspections (photo / video recordings) are possible for the planning phase or directly during the construction work. Surveying Drone's (UAV / UAS) are an adequate means of documenting aerial photography or documenting regions that are difficult to access.

Applications areas:

• Industrial facilities
• Photovoltaic installations
• Wind turbines
• etc.


To use your construction project as data basis, our drones are an ideal solution. In conjunction with predefined reference points we achieve accuracies in the low centimeter range. Thus, we can process volume and height models and visualize it. This solution is mainly used for large-scale projects, because drones are very efficient here.

Applications areas:

• Construction industry
• Open-cast mining
• Industrial facilities
• etc.

Tunneling


A reference point network is fundamental for an exact heading control and  quantity survey. from planning and implementing of the measurements to network calculations and control measurements we provide all necessaryy steps of the process. We therefore implement static GPS measurements, precision levelling and tacheometry. Finally we transfer the reference point network into a superior level system according to contractors requirements.

We cover all areas of a drive with TBMs from steering the tunneling machine with a network prognosis and/or stabilizing with gyroscopic measurements to evidence backup procedures accompanied by fully automatic structure monitoring systems.

We cover all areas of surveying for conventional tunnel drives:
• partial stake out and controlling
• profile controllling
• adjustment of gearing lasers
• layer thickness measurement
• installation of piperoofs

• Settlement and gradient measurements with fully automatic systems
• Elevation and position observation with highest degree of accuracy
• Settlement, tipping and warping measurements of pylons, vaulted structures, bridges and other structures
• Movement and expansion measurements of machines and other construction parts based on graphics and diagrams recognizing structural changes
