How Building Inspection Drones Improve Safety and Reduce Costs

Introduction

Inspecting your building once or twice a year is necessary if you want safety and long-term use of your property. Although this exercise involves risks, high costs, and can be time-consuming, it’s usually worth it at the end. While traditional methods of inspection require inspectors to access rooftops, scaffolding, or hard-to-reach areas, thus exposing the life and safety of workers to potential hazards, drones eliminate this. Not only do drones enhance safety, but they also reduce labor, equipment, and operational costs. In this article, we will walk you through how building inspection drones improve your safety while reducing costs. 

Challenges in Traditional Building Inspection

As an engineer and architect, utilizing traditional inspection methods means you’ll incur costs on access tools, climbing gear, insurance, and traditional labor if you want to inspect with rope access or swing stages methods. With this, you will have increased inspection costs. In fact, the main reason home or building owners avoid inspecting their homes is due to the high cost required for traditional building inspection.

Remember, as your building becomes taller, the risk of falling also increases. With this, you may not even be able to access taller and bigger buildings because your ladder may not be long enough, and you may not even inspect the buildings efficiently, even when you spend so much to acquire expensive access and safety equipment. This means it’ll be riskier, complex, and more expensive if you want to inspect complex buildings.

The risk of using traditional building inspection is beyond just falling when you want to access the roof; it comes with other risks like a collapsing structure, electrocution by overhead power lines, etc. Therefore, since there is an increased risk, the cost of equipment, personnel, and insurance policies for homeowners becomes higher. 

Despite all the stress and cost that come with these inspection methods, there’s no guarantee the inspectors will get comprehensive details of hard-to-reach areas. This happens mostly because the inspectors are limited to how close they can come to the structures or surfaces, tight spaces, or limited access to the areas that climbing gear cannot reach.

How Drones Improve Safety in Building Inspection

While it poses a high risk and cost for you to utilize traditional inspection methods to access some parts of buildings, the new unmanned aerial vehicle technology has made it easier. Today, professionals utilize drones for inspection of personal and commercial applications, and it has been confirmed to be one of the safest and cost-effective ways of inspecting your buildings. 

With drone-based inspection, the risks and high costs that you must incur when you’re inspecting with manual or traditional building inspections are eliminated. Not only do drones help you reduce cost, it give you easy access to almost all hard-to-reach areas, capture detailed photos, videos, and thermal images. Additionally, with drones, you can inspect a building in a fraction of the time and cost since you don’t have to spend on expensive access equipment. 

Drones allow you to safely carry out the analysis of your inspection work without going up through ladder, or incur expenses that come with tools like scaffolding. All you have to do is operate it on the ground, and a drone that can scan the roof in the desired pattern. This helps you minimize safety risk as a technician and others who are within the building premises. 

Drone guarantees capturing of hundreds of images that traditional inspection tools cannot reach; the UAVs easily identify problems you cannot identify as a technician using traditional methods or your naked eye. This makes it possible for you to inspect complex roofs and structures without leaving the ground. 

With the help of new technologies, you can program the drone to take photos and video at the exact height and location. You can operate the drone to do the capturing as much as you want. Meanwhile, traditional inspections may not provide the best comparison because the way inspectors position the camera and the angle from which they capture images may differ between different shots or individuals. 

Cost Reduction Through Drone-Based Inspection

Modern technology guarantees you a reduced cost of inspection. The list below shows how drones help you cut costs while improving efficiency, safety, and overall project outcome: 

• Eliminates Expensive Access Equipment: Drones reduce cost by eliminating the need for costly scaffolding and lifts, thus making you complete your inspection work quicking without having to spend on specialized access equipment.
• Reduces Labor Costs: Aerials access buildings faster, thus reducing labor hours, cutting overall inspection costs while improving productivity and operational efficiency on job sites.
• Minimizes Safety Risk: Since inspectors operate the drones from the ground, safety risk is automatically reduced, making you spend less on insurance and possible liability you may incur from accidents or hazardous environments.  
• Prevent Operational Downtime: Drone capture data without interrupting operations, thus minimizing downtimes and eliminating costly shutdowns or work delays of your business operations.
• Identify Issues Earlier: High-resolution drones come with advanced sensors and software to detect small issues in buildings early to eliminate expensive repairs that may occur later in the future and avoid major structural or maintenance failures.
• Improves Long-term Maintenance Planning: The consistency and repeatability of drone data help you plan your asset long-term, thus minimizing unnecessary maintenance expenses and extending the lifespan of building parts.

Types of Building Inspections Suitable for Drones

In this section, you’ll find out the various types of building inspection suitable for drones, each giving you a precise result in hard-to-reach or hazardous areas.

Roof Inspections

Inspecting your roof with drones guarantees high-resolution aerial images that show damaged shingles, leaks, flashing issues, and structural concerns. With this approach, you eliminate risky manual climbs, reduce inspection time, and guarantee you’ll get accurate inspection of large or complex roof areas.

Facade Inspections

In Facade inspections, drones guarantee you detailed visuals of building facades, identify cracks, loose materials, water damage, and weathering. As an inspector, drones help you to safely and efficiently evaluate tall buildings, without scaffolding, lifts, or disruptive exterior access equipment. 

Structural Inspection

As an engineer, you can examine beams, trusses, joints, and load-bearing components in hard-to-reach areas with drone-based structural inspections.  Using drones for your structural inspection guarantees inspection safety, enhances documentation, and provides clearer insight into potential weak areas of your structures, and helps you identify early signs of deterioration.

Thermal Inspection

Some drones come with thermal imaging sensors. With the sensors, you can use the drones to detect heat loss, moisture intrusion, insulation gaps, and electrical hotspots. These inspections give non-invasive diagnostics, allowing the drones to quickly detect hidden issues that you’ll miss if you’re using destructive testing to uncover them. 

Solar Panel Inspection

Inspecting your solar arrays with drones allows you to quickly identify malfunctioning panels, shading problems, wiring issues, and dirt accumulation. This efficient aerial approach guarantees reduced inspection labor, maximizes system uptime, and improves the overall performance and maintenance planning of solar installations.

HVAC and Mechanical Inspection

Drones do a great job when it comes to evaluating rooftops, HVAC units, vents, and exposed mechanical systems without any shutdown or physical access. With this approach, you’ll get visual data, reduce inspection risks, and help you identify the areas of maintenance in time before they become serious issues.

Technologies Used in Drone Inspection Systems
