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

The future of drones in the construction industry

Drone usage is growing fast. They are very valuable on construction sites and built asset maintenance. They are used to:

• make land and existing building surveys
• keep track of machine inventory
• improve safety

Drone technology is evolving very quickly. In December 2020 xFold drones, was introduced. They have a capacity of 1,000 pounds, 8 hours flight time and interchangeable rotor configuration. This drone can: - transport heavy loads on worksites - develop 3D maps thanks to their sensors and robotic arms.

Drones can already:

• cut costs
• save time
  
• mitigate risk
• reduce labor
• streamline processes
• increase quality and accuracy
• allow efficient collaboration

What can we expect drones to do in the future?

• direct and guide autonomous vehicles
• further streamline the construction life cycle
• change the way projects are managed
• monitor quality
• identify potential safety issues
• simulate the position of cranes to ensure safer, more seamless operations
• enable site traffic to continue as normal, without the need to temporarily shut down operations to allow surveyors access
• provide large amounts of reliable data including map-quality images, digital surface models (DSMs), and detailed point clouds to architects and site managers will enhance the 3D modeling process.

Drones, which are also named Unmanned Aerial Vehicles (UAV):

• are cost-effective
• help streamline operational efficiencies
• increase profit margins
• improve safety
• drive innovation across the industry
• offer new ways for the future of mapping in the construction space.

Construction Drone Market Forecast

The global construction drone market is projected to reach $12 billion.

Covid 19 lockdown in many countries has slowed down the growth of the drone market in the construction industry.

You can envisage manual operation and automated operations of construction drones remotely to get an aerial view of a construction site to:

• see where the material is located and should be delivered
• locate people and machinery to reduce the probability of accidents
• improve safety and security
• inspect structure
• survey a field to map the geography of a site
• facilitate data acquisition in real-time
• capture accurate images
• access hazardous areas

The global need of building new houses supports the growth of drone demand, to fulfill the need for surveying large lands with difficult access being on uneven terrain or containing rocky obstacles.

Drones are perfectly adequate to perform these tasks efficiently and quickly reducing the need for human intervention.

Initiatives similar to the Survey of India (SoI) are expected to drive the construction drone market growth during the forecast period.

With the use of drones and other technologies like GPS and artificial intelligence to make mapping activities easier and more efficient, SoI, has undertaken the mapping of the Village Gaothan (Aabadi) areas in the State of Maharashtra covering more than 40,000 villages. Similarly, drone-based mapping for five districts of the State of Karnataka for the revenue departments including village, semi-urban and urban areas has also been undertaken by the SoI. SoI has also initiated latent semantic mapping for the complete state of Haryana using drone technology.

Governments in various countries have been under pressure to invest in residential and infrastructure construction to develop their economy and improve the standard of living. For example, Japan invested $367 billion in infrastructure projects in Southeast Asian countries such as Indonesia, Singapore, Thailand, and the Philippines.

These initiatives will help the construction industry worldwide to grow, expanding the need to use drones and contributing to the growth of the construction drone market during the forecast period.

In the U.S., Canada, the UK, Europe, Russia, India, China, and Brazil urbanization expanded due to a high rise in the population and posed major implications for the built environment and demand for housing in the short- and long-term. For example, Canada's total investments in building construction registered an increase of 12% in June 2020 as compared to May 2020.

Never in the history of warfare have drones been used as intensively as in Ukraine. Russians and Ukrainians depend heavily on unmanned aerial vehicles to pinpoint enemy positions and guide their hellish artillery strikes. The drone fleets of both sides are depleted, and they are racing to build or buy drones.

The drone construction market could then be slowed to fulfill this new demand on the drone market.

Rotary wing drone

This segment is projected to grow significantly.

Construction drone margins are negatively impacted by expensive specialized equipment:

• camera
• battery
• remote control
• propeller
• GPS antenna.

This is expected to hold down the growth of the market.

Another negative impact on the global market growth is the lack of skilled manpower for designing, developing, and operating drones.

The drone offering

The drone offering is continuously improving to fulfill the needs of our industry. For example:

• The US-based TraceAir company provides an integration platform that combines topographic information, site measurements, and other data collected by drones into any handheld device. As a result, civil engineers and construction supervisors have optimal visibility of the progress of construction in real-time.
• The Israeli start-up Cividrone provides solutions for land surveying using smart stakes. Drones help deploy stakes in the construction sites in line with the engineering designs.
• In the UK the company British Sees.ai offers remote drone operation solutions to construction companies. The control room simulates a virtual reality (VR) environment on-site that enables pilots to navigate the drones remotely. As a result, this increases efficiency, on-site worker safety, and profitability.

Land surveying in dominant position

Advance technologies are coupled with drones to improve the surveying of lands:

• global navigation satellite systems (GNSS)
• global positioning system (GPS)
• geographical information system (GIS)
• Internet of Things (IoT)
• thermal imaging
• artificial intelligence (AI).

For example, drones can create 3D models of large areas with laser scanners combined with a standard topographic survey, and put in computer programs to identify what earthwork volumes are present on the construction site.

Segmentation

The global construction drone market is segmented into:

Types: fixed-wing drones and rotary-wing drones

Application: surveying lands, infrastructure inspection, security & surveillance

Clients: end users, residential, commercial, and industrial.

Regions: North America, Europe, Asia-Pacific, and LAMEA. Asia-Pacific holds a dominant position in 2019 and is expected to grow at a significant rate during the forecast period.

Drone usage

Data produced by drones are used throughout the construction lifecycle, from feasibility to maintenance.

Bidding and pre-planning

A topographic survey of the site with drones allows you to understand the environment of the future project even during the strategy phase to show the possible:

• drainage points
• changes in elevation
• locations for building, digging, or storing materials.

Planning and design

You can use the topographic survey imageries in the BIM Execution Plan to collaborate with architects, local authorities and engineers.

With a drone, 3D models, and augmented reality you can display an as-built building on the site to:

• get a clear picture of how a digital building may look next to an existing one
• assess how the new project will impact the area practically and aesthetically
• allow analysis and visualization of cast shadows and views
• import data such as curbs or manhole measurements into your CAD or GIS software to enrich existing data.

Maintenance and asset inspection

Maintenance may cost you a lot of money and time if you are using traditional facility management tools. To prevent serious problems you have to ensure the quality and maintenance of your assets at reasonable costs. Drones sent to visually inspect your assets and knowing exactly where the assets are located makes the whole process much easier even in hard-to-reach and hazardous areas. It is cost-effective and brings you accurate data in real-time

Construction

The construction phase is where the drones will bring the highest value.

Earthworks

By importing drone images in software you will be able to:

• generate a point cloud containing geospatial and color information
• get precise volume measurements and run a cut/fill analysis
• measure accurately the amount of earth moved so you can save money as you will know exactly how much to pay the contractors

As-built vs. as-design

Accurate site visualization allows you to compare what was actually built and overlay it over the design to identify differences between planned and real-time progress, and correct errors very early on to avoid costly reworks.

Site progress monitoring

Using drones to survey progress allows you to check and validate the completed work on site every day so you can move on to the next task, shortening the construction process and making sure that deadlines are met.

Communication and collaboration

Monitoring progress with drones in real-time allows all stakeholders in their respective locations to know how things are progressing. It is more efficient and less costly than traditional site visits or helicopter images that are out of date the minute they are taken.

So, you can:

• update the schedules of the operations as needed
• explain how the work should be performed
• identify safe or hazardous areas
• send visual reports to customers about timing and budget.

Rework and litigation documentation

When your project is moving forward, and it reaches a milestone, you want to be sure that everything has been achieved to the highest quality standard. Further construction is based on that milestone, so if something has been done wrong, you’ll eventually get stuck, and you may have to tear down what has been done previously. Having up-to-date visual data can help you catch a mistake before it takes shape and avoids demolition and the waste of time and materials related to it.

And if a mistake happens, and it is built over, you have regular documentation of the process, and you can check back to see where the mistake occurred more precisely and settle disputes without lengthy discussion, or even court cases.

Handover

Detailed documentation presents advantages to both the contractors and the site owner, who will take over the responsibility of the project once complete. Specifically, the owner can look carefully through the documentation before agreeing to the handover, and contractors can prove that the work has been conducted as per requirements, including details on who did what.

In Conclusion

The drone market is expanding at high speed and is here to stay.

Drones can be used in all phases of a construction project. You can envisage manual operation and automated operations of construction drones remotely to get an aerial view of a construction site to:

• locate machinery, material, and people
• improve safety and security by flying drones over hazardous areas instead of sending people
• inspect structures
• survey a field to map the geography of a site capturing accurate images
• facilitate data acquisition in real-time.
