Goals

An indication of what impact the use of drones has on volume measurements and monitoring of construction progress on a project. This will be a comparison of classical methods (GPS measurements) with a modern approach in the form of 3D data from a drone and the SkySnap geoportal as a volume measurement tool.

Challenges

  • Conducting coverage surveys at the aggregate landfill (5ha) and the expressway construction site (20km).
  • Short time to implement measurements due to the dynamics of construction site changes.
  • The result of the work as a report necessary for billing between construction companies.

Comparison

Measurement of aggregate stockpile

Area: 5ha
Measurement time including processing of results:
GPS: 8h (measurement) + 4h (report)
Drone: 1h (measurement) + 3h (report)
Savings: 4h

Measuring the volume of heaps at the construction site of an expressway

Length: 20km
Measurement time including processing of results:
GPS: 5 days (measurement) + 2 days (report)
Drone: 2 days (measurement) + 1 day (report)
Savings: 4 days

Leveraging the Data Advantage
in Construction
FMI & Autodesk Report

  • 30% of all bad decisions in construction projects are due to bad data
  • The cost of construction alterations can be as high as 5-10% of the total contract value
  • More than 50% of rework is due to bad data and lack of communication on the project

BENEFITS

  • Time – the use of drones is the fastest and most informative method of surveying construction.
  • Safety – The person performing the survey does not have to enter the heap and does not stop other construction work.
  • Lack of generalization of the data – the density of the measurement data gives the opportunity to better reflect the measured terrain compared to classical methods.
  • Archiving – the ability to ‘freeze’ the construction status for the day of the raid.

    Managing a modern building is a constant battle against the passage of time and the destructive influence of nature. Whether you're looking after an office building, an industrial hall or a housing development, the greatest dangers lurk where the eye can't see - in the highest parts of the structure and in hard-to-reach places. The roof, gutters, flashings and facade details are the front line in the clash with rain, frost and UV radiation.

  • Webinar: 23.04 Drones in Real Estate: Roof Inspections

    The roof is one of the most expensive parts of a building... especially when problems are noticed too late. Leaks, damage or lingering water often remain invisible without an expensive and risky visual inspection.

    What if you could check the condition of the roof quickly, accurately, and without climbing high?

    During the webinar, we will show how to use roof inspection drones in practice - not just to take pictures, but to create real-world useful documentation that supports renovation decisions and conversations with contractors.
