This article is part of a blog series on drones, exploring what drones are, and what they can do for the construction industry.

Drones can play a fundamental role in site safety. It is easy and safe to navigate a drone around your construction site, to discover early and worrying signs of hazards and safety risks. They can warn site managers to take early corrective actions by:

• scanning assets and structures under construction
• detecting faults such as leaks or cracks.

Can drone technology change the construction industry?

Drones can be seen everywhere but what are their uses in the construction industry?

You can fly drones inside a building to survey a specific room, or outside to scan hazardous sites. The possibilities are endless as drones can be used in various applications.

Drones are very trendy right now in the construction industry, thanks to their ability to collect data. They offer great benefits in:

• surveyance
• site monitoring
• site safety and security
• project management.

Drone technology can be used throughout the whole life cycle of a project:

• scope the project by collecting rich media like photos, videos, and imagery that can be inserted into the BIM Execution Plan ( BEP)
• track the construction progresses in real-time
• optimize the efficiency and usage of construction by collecting real-time data.

Types of construction drones

Drones used in the construction industry are mainly commercial drones, and their usage is growing fast. Drones are very beneficial to survey terrains in the field by tracking and recording machinery.

You can use two different kinds of models. Their usage depends on why and what you want to do with them.

Fixed wings

Fixed wings drones are mainly used for mapping and scanning long distances. Their design is similar to airplane designs, allowing them to fly over a specific place at high altitudes along a pre-set path. They are very helpful to streamline pre-construction processes such as:

• mapping terrains
• surveilling large and hazardous areas

The downside is that they can only fly forward so they are less maneuverable in narrow areas or on terrains with a lot of obstacles.

Rotating blades

Rotating blades drones are mainly used for inspecting and surveying short distances. Their design allows them to fly without moving forward and stay still over a specific area, which makes them more manageable than fixed-wing drones. They are efficient in:

• birdlike inspections
• structural scans
• aerial photos
• short distance supervision

The downsides are that they may be unstable, complex, and less efficient than other drones.

Drone features

Drones are supplied with many features to help capture data on construction sites:

• cameras to get high-resolution pictures and videos
• GPS systems to monitor longitude, latitude, and elevation points
• Infrared, heat and cold sensors can monitor temperature and take thermal images

These features streamline the project management life cycle processes and increase efficiency and productivity. Drone software captures the information and sends it to computers via the internet so the data can be:

• analyzed
• interpreted
• organized.

Drone benefits

Drone capabilities directly impact the construction life-cycle allowing the industry to improve:

• processes
• accuracy
• communication
• visualization
• efficiency
• confidence and certainty in project management.

While the impact of drones in the construction industry is developing, they are already revolutionizing the sector and changing the way construction projects are handled. As long as the technology is able to pass aviation laws and zoning hurdles, it is safe to say that the commercial drone is here to stay.

The complexity of projects, as well as the requirements for sustainability of the existing buildings, are the main reasons for the exponential use of drones in the construction industry. Below we explore how these devices are transforming the industry

Why should you use drones in construction?

The main qualities of drones are their ability to:

• fly
• record data in real-time
• improve efficiency
• cut costs
• streamline workflows.

Here are some examples of how to use drones in construction.

Contour Mapping and Terrain Surveys

Depending on the type of drone you are using you can save up to 20 times the cost of creating a topographic map using traditional methodologies.

Before designing complex, large-scale construction projects, drones can:

• expose potentially, costly, design errors
• complete feasibility studies
• aid with design.

With drones, you can not only produce accurate maps but also update them during the start of the construction. The two types of drones can cover:

• fixed-wing 900 acres, in one-hour, maximum flying time
• multi-rotor 200 acres, in 40 minutes, maximum flying time.

The teams will also be able to use software to create 3D models, from the data collected, to streamline and speed up the planning and analysis processes you may use in your projects. Thanks to the drone’s high-resolution imagery, you will be able to:

• keep the project on schedule and on budget
• ensure accuracy and quality of the design
• overcome challenges during pre-construction

Progress tracking

Drones can be used to:

• track equipment to know where they are located on the construction site, and redeploy them
• record measurement errors and systems malfunctions to proactively plan maintenance
• drive and guide machines using artificial intelligence to avoid costly damages.
• prevent expensive, accidental renting charges, for equipment not in use
• diagnose and solve recurring issues by providing visuals to understand the problem

Remote Reporting and Monitoring

Companies using drones claim that they have improved their communication between all stakeholders by 65%. This was achieved by:

• capturing data in real-time
• sending photos and videos through the internet
• providing progress reports

Drones increase visualization which improves client satisfaction by:

• providing aerial views of the project’s advancements
• reducing costs, clients do not have to visit sites
• reinforcing that the client’s spending is properly and efficiently used
• improving internal collaboration through connected software during handover
• giving simultaneous access to data helping to follow up on projects and catching errors early during the design phase
• creating a document trail that will be useful in audit and facility management

Security inspection

With drones, you can make sure that:

• your assets are safely secured
• detect any unauthorized individual on a construction site.

Many companies have experienced theft on their sites, which costs a lot of money. In between $300 million and $ 1billion of equipment, according to Gulfshore insurance, are stolen every year from construction sites and it is increasing year after year. Less than 25% is recovered.

Securing your equipment with drones is very easy and important, it will mitigate the risk of theft and save you a ton of money. You will be able to monitor people that are on-site and prevent unauthorized individuals to steal your equipment.

Worker Safety

Construction sites are notoriously dangerous with a high risk of injury or even death.

Using drones for inspection and safety checks can save thousands for the construction industry, especially in phase audits and works certification costs. DroneDeploy claim that their customers saw a 55% improvement in their construction sites' safety. They can achieve that performance by:

• making a hard measurement on hazardous areas with drones
• monitoring falls to prevent accidents as 34% of fatalities are due to falls.

You should use drone video cameras to monitor your sites to:

• eliminate safety worries
• make sure workers are secured when measuring difficult areas
• prevent unstable structures
• tighten your equipment

Renovation inspection

In renovation projects, you use drones to capture data of the built conditions of the construction to:

• reduce costs by eliminating measurement issues and unnecessary costly reworks
• create marketing documents
• eliminate the use of scaffolding
• check structure stability
• analyze data to improve sustainability
• detect heat leaks, cold spots, and any electrical issues with thermal sensors
• plan preventative maintenance
• reduce the workforce

In Conclusion

Drones are not considered a toy anymore, they are a mature technology for the construction industry. They are helpful to:

• survey sites in the pre-construction phase of a project
• remotely map potential sites before construction starts
• minimize the use of the human workforce in hazardous and risky terrains
• optimize the needs for trips to construction sites from non-site crews
• produce high-resolution images with much superior quality than the traditional surveying methods
• allow planners to spot potential issues early enough to avoid costly reworks
• permit efficient and effective deployment of equipment
• enhance safety and security
