STRABAG is a European engineering group
for construction services, headquartered in Vienna.
STRABAG is one of Europe's largest construction companies
and we cover all services related to the building industry.
In 2015, we started using drones for surveying
and 3D data acquisition, to achieve efficiency gains
for internal and external clients.
This integration had an impact on our workflows
and simplified many steps in our operations.
The placement of ground control points,
used to be a time consuming process.
In the past we needed 20 to 40 GCP per square kilometer
which takes several hours to plan.
By deploying the Phantom 4 RTK, we can reduce the amount
of GCPs to 55 and even to zero under circumstances.
For us, the Phantom 4 RTK is another step forward
in making construction surveying with drones simpler.
It is compact and flexible
and therefore can be a useful tool for our team at STRABAG.
In order to use all benefits of the fully integrated system,
in RTK mode we are using network RTK services.
To achieve even more accurate results, especially in areas
with bad mobile network coverage, the D-RTK 2 Base Station
can be connected with ease.
The long battery life of up to 30 minutes,
lets us map large areas in a single flight.
The Phantom 4 RTK provides
an integrated flight planning app in the remote control.
Including all relevant terrain parameters
to make the flight planning easy and efficient.
This solution helps us to gather consistent data
that can be easily processed to continuously produce accurate results.
If the area is too large to map on one single battery charge
the Phantom 4 RTK will automatically resume the mission
after the battery has been replaced.
Without ground control points,
the achievable horizontal accuracy is up to two centimeters.
This is the foundation for delivering good results
in volume calculation, terrain modeling
and progress monitoring.
Phantom 4 RTK also offers the opportunity to choose
between RTK and PPK.
After the flight, the data is uploaded onsite
to the cloud to be processed by the surveyor's preferred
post-processing software.
Drone generated survey data is comprehensive,
which is an advantage for detailed 3D modeling
and related evaluations.
Thanks to the Phantom 4 RTK's
consistent data capturing process,
engineers are assured that they receive the necessary models
according to their project requirements.
In due time, the models are available
for the engineers onsite to download.
Drones prove to be very efficient tools
in the construction industry
and I am convinced they will be integrated
into the construction processes internationally
more and more.
As an innovation leader, it's our protocol
to execute complex construction projects
with highest quality and deliver on schedule.
The Phantom 4 RTK contributes in many aspects.
We are looking forward to working with the Phantom 4 RTK.
