Drone Facade Inspection

Drone Facade Inspection In Dubai

Tired of old-school building facade surveying methods?  Use drone facade inspections to analyze building structures, find defects and ensure the safety of residents.

The United Arab Emirates is the global real estate epicenter. Businesses worldwide see the region as the safest bet to earn a handsome return on investment. It is a pre-requisite if you want to own a house or real estate here. This article will teach us how to do a facade inspection with drones.

What is Drone Facade Inspection?

Drone facade inspection is a holistic survey of a high-rise building’s exterior surface and appearance with the help of a drone. Drone inspections have revolutionized the industry. They have become central to a building’s maintenance and management plan.

During the procedure, a qualified inspector visits your high-rise building and generates a written report per the country’s laws. For buildings with six or more floors, a facade inspection is recommended after every five years.

A drone facade inspection is superior to traditional methods. Not everyone can afford a plane to inspect a building; it isn’t economically viable. A drone is quicker and more economical. When collaborating with AI and Google Mapping, it gives more accurate results.

The drone can visit areas you can’t physically access and gives real-time videos and images. With the drone, you can inspect the quality of structure, strength of binders, possible defects, water infiltration problems, and building wear and tear.

    Drone Facade Inspection

    Carrying out a physical inspection at a busy construction site can be dangerous and may raise various safety concerns. With the use of industrial drones to carry out inspection works, precise and accurate visual data can be acquired with ease; the data collected can be used for a myriad of purposes.

    Building Facade Inspection

    Conventional drone building inspection would require the erection of a scaffolding which can be time-consuming, costly, and risky. The use of a drone would eliminate those problems. By identifying potential building issues through thermal imaging analysis, faults can be rectified accordingly.

    Roof Top Inspection

    Maintenance inspection on high structures such as towers, roofs and bridge inspection using drones incur extra costs, and cause issues of access arrangement and personnel working at height. Drone inspection provides the fastest and easiest solution to acquire details of the structures; the engineer on the ground can receive real-time footage during the process.

    What are the Key Factors for Best Drone Facade Inspection?

    For the best drone facade inspection, there are some conditions. The first thing you need is a quality drone and a qualified pilot. A quality drone is determined by its range, air time and camera quality. Check out GIS drones to select the best drone for facade inspection.

    After that, hire a licensed operator. Because in the UAE, unqualified personnel can’t fly a drone. Now, you are set to go. However, there are four essential elements that decide the fate of any drone inspection.

    • GPS Signals
    • Drone Flight Path
    • Camera Focus and Angles
    • Take-off Point/ Height of flight

    GPS Signals

    GPS signals are mandatory for stable drone flight. They also help in the accurate processing of data points for automation analysis. So before the flight, always check the availability of GPS signals.

    The high structures often block GPS signals. If that’s the case, you should alter your take-off location or try flying at a higher altitude to get GPS signals. If nothing works, then you can turn on non-GPS ATTI control.

    Camera Focus and angles

    The camera angles are everything when it comes to drone inspection. You should find the ideal range to take pictures and videos. The walls shouldn’t look too big or small; it eludes judgment.

    The images should be clear. Always focus the camera to get sharp images. For that, you should hire a drone with the best camera lens.

    Drone Flight Path

    For any drone inspection, the flight plan is vital. You should decide a clear path before the flight, as every drone has a limited flight duration.

    The path depends upon the number of facades you want to inspect and the sizes of these facades. For tall buildings, it is advisable to fly a drone on a vertical plane (up and down motion). For short structures, you should look for horizontal flights (right to the left). This way, you can capture the maximum data in a limited time.

    Take-off Point/ Height of flight

    Drones have a limited flying range. For that reason, you should pay special attention to the take-off point. The drones use a barometer to find their relative altitude from the point of flight. This relative altitude decides the area your drone can visit.

    For high-rising buildings, the drone should fly from a point where it can reach the top within safe limits. The original manufacturer describes the safe limits of each drone.

    What is the Procedure for Drone Facade Inspection? 

    The procedure of drone facade inspection involves three stages.

    • Site Visit 
    • Drone Imaging
    • AI-Based Building Analysis
    • Reporting

    In the first step, the hired facade inspection agency sends a field team. This field team will visit your site to analyze the type of drone and the analysis required. Based on their input, the drone, lens, and flight path are determined.

    In the next step, a qualified pilot flies the drone along the designated path. The camera is focused on getting optimally high-resolution images and videos. It serves as input for analysis.

    It is the most critical step.

    AI-based algorithms and machine learning are used to identify the material, it’s grading, and its current conditions. The software shows the strength of the structure. With advanced mapping techniques, you can also determine defective areas. Advanced software can predict the life of a structure as well.

    Lastly, the quality department generates a comprehensive facade report. This report gives enlists complete analysis and suggestions per the laws of the land.

    The Bottom Line

    Drone Facade Inspection is the present and future of real estate surveying. The process is quicker, safer and more accurate than all traditional methods. If you want to compete in UAE Market, the facade inspection isn’t a choice; it’s a compulsion.
    At GIS Drones, we provide drones equipped with high-resolution cameras and the latest AI-based algorithms. Contact us for using drones for inspection as per your requirement.
