In the wake of Industry 4.0, many companies have tried to utilise automation and data exchange in manufacturing technologies. This is especially prevalent in the construction industry where the need for increased efficiency and delivering a quality product both, physically and digitally has now become a necessity rather than an indulgence. Many technologies have sprung up to meet the challenge, such as artificial intelligence (AI) and drones.
Call it a drone, Unmanned Aerial Vehicle (UAV), Unmanned Aerial System (UAS) or Remote Piloted Aircraft System (RPAS), it usually involves a flying platform that is remotely controlled by a pilot assisted by flight software, onboard sensors and Global Positioning System (GPS) / Global Navigation Satellite System (GLONASS). It has a payload which is usually a camera system, but could also be technologies such as LIDAR (Light Detection and Ranging) and thermal cameras. There is shared telemetry between the drone and the ground control station which enables the pilot to fly in a stable manner.
The numbers
DroneDeploy, a cloud software platform for commercial drones has compiled statistics on drone usage based on 100 million aerial images from 400,000 job sites in 180 countries in 2018. Below are some of the findings:
• The construction industry has seen an increase of 239 percent in the adoption of drone technology. The other two industries directly related to construction, namely surveying and real estate, have an increase of more than 100 percent for each industry.
• There are many benefits that are associated with the use of drones in construction, namely increased safety, cost saving and better data collection and usage.
• Drones are primarily used for progress tracking and communication, preconstruction and site planning, quality control and assurance, bid process preparation and job site risk mitigation.
55 percent of DroneDeploy customers report increased safety as a result of implementing drones.
The why
Accenture indicated in their article titled, “A business approach for the use of drones in the Engineering & Construction industries” that drones “optimise project and maintenance costs”. In the current business climate, being able to optimise project costs and maintenance costs is crucial for the viability of a business.
A drone allows for tasks to be automated and conducted in parallel with operations. Inspection can now be done while the construction is being undertaken. Various drone platforms now allow for automated drone operations that provide vital information for construction, such as cut and fill parameters, volumetric analysis of stock piles, comparison against design data and conducting accurate and repeatable topographical surveys.
Drones also “reduce workers exposure”. Health and safety are a crucial element on all construction sites. Drones allow access to dangerous areas (working at height, chemical exposure, heat exposure) which were previously deemed as high risk to personnel and cost intensive. For example, an inspection of a rooftop would utilise scaffolding and harnesses, which take time and effort to setup, whilst a drone could capture a wealth of data in a fraction of the time and cost.
But that’s not all as drones also “enable best decisions to improve quality”. The key element in the progression of technology is the ability to provide humans with better information to be able to make better decisions. A bird’s eye view of a live construction site allows for accurate decision making based on real-time information as opposed to relying on narratives and benchmarks. Another element that drones bring is that data collected can be reviewed for lessons learnt, comparison for benchmarking and general archiving.
The who and where
Many construction companies around the world have started using drones as a vital tool in their projects. International companies such as Kier, Balfour Beatty, Vinci Construction and Mitie have started to use drones as a tool on site. On the Malaysian front, projects like the Tun Razak Exchange (TRX) and various rail projects such as the Mass Rapid Transit (MRT) extension extensively use drones for project monitoring and various land use analysis. It is becoming more and more commonplace in Malaysia for drone operation in data collection and analyses.
Drones are perfect for all manner of construction, engineering and inspection projects as they provide the ability to work in an automated manner and collect data that allows for better decision making.
The when
Now is the time for companies to make the shift towards the many benefits that come with responsible drone operations. There are two ways to achieve this. The first is to hire a professional drone company that complies with the various regulatory requirements. Some discussion is usually required at the start to ensure the deliverables are in line with the need of the construction project.
The second option is to develop drone capabilities in-house to the company. The best way to achieve this is to hire an external consultant that could guide you through the process, thus speeding up the time to setup a competent drone team. The consultant will guide you through the process including purchasing, operation manual setup, audits, maintenance plan, training and software selection.
The next step
Drones will continue to improve and become commonplace in many industries. With AI starting to move into the drone space, the amalgamation of these two cutting edge technologies will produce a quantum leap in useable data that will help reduce cost, increase safety and maximise performance. The construction industry has to maintain a view of the future which will certainly include the use of drones, so as to ensure that it remains relevant and competitive in this ever-changing world.

Commercial drone use on the job site is skyrocketing. The latest drone trends and statistics from DroneDeploy explain why.
This past year, more than 30,000 users put DroneDeploy to work creating the largest drone data repository — now with over 400,000 maps of job sites, farms, and structures. Our growth is a testament to the growing community of commercial drone users.
While dozens of industries use drones, the fastest growing commercial adopter is the construction industry. Drone use on the job site has skyrocketed in the last year — surging 239% — and construction is now the leading sector using DroneDeploy.
With growth like that, you probably have some questions. How are companies putting drones to work? Who exactly is benefiting from drone data? And what are the results?
In this post, we share some recent insights uncovered from analyzing the latest DroneDeploy user data. Read on to get the most recent trends and statistics from drone data captured on 400,000 job sites in 180 countries.
Who’s Using Drones on the Job Site?
We talk a lot about what’s possible with drones on our blog, but who is actually taking advantage of the technology?Project managers, technology managers, and superintendents are the top roles benefiting from drone data to date.
It’s no surprise that project managers are leading the charge to bring drones to the job site. The typical project runs over budget, behind schedule. Drones help close the gap.
How are Drones Put to Work in Construction?
Builders use drones to collect real-time data about projects and understand what’s happening on site. Aerial insights improve progress tracking and help catch problems early — before they become costly or add weeks to a project’s timeline.
But progress tracking is far from the only way construction companies use drones. By spending less than an hour each week mapping a job site, contractors gain access to an unprecedented amount of knowledge about nearly every aspect of their project. With this data in hand, DroneDeploy’s software makes it easy to plan, communicate, and keep projects on schedule.
How are Construction Companies Benefitting from Drones and Aerial Data?
Drones do more than improve communication and help keep projects on track. They also increase safety, save time and resources, fast-track surveying, and deliver accurate measurements. We surveyed our construction customers to see exactly how use drones on the job site. Here are the top results.
We reached out to our construction customers earlier this year, and they reported a wide range of benefits from using drones. Explore the infographic below for the complete breakdown of the results.
What Software Tools are Construction Pros Using with Drone Data?
While thousands of construction customers use DroneDeploy on a weekly basis to collect, process, and analyze drone data, added value comes from incorporating maps and 3D models into existing planning, design, and management workflows.
How Accurate is Drone Data Captured on the Job Site?
As construction companies turn to drones for aerial data collection, we’ve seen a rise in the demand for higher data accuracy. Today, companies are using ground control points (GCPs) — ground markers measured with GPS to calculate absolute global positioning — more than ever before with DroneDeploy. The number of maps processed with GCPs grew 5X in 2017 and is currently increasing at a rate of 20% each month.
Measurements are also more common with construction customers. Construction companies use DroneDeploy’s built-in analysis and annotation tools to calculate area, volume, and distance accurately. Exactly how accurate are drone measurements? Using GCPs, customers achieve 99% accuracy. Learn more in our white paper: Linear Measurement Accuracy of DJI Drone Platforms and Photogrammetry.
What are companies measuring? Stockpiles are some of the most common things measured with drones on the job site. In 2017, DroneDeploy users measured more than 300,000 stockpiles to estimate value and track volume changes over time.
Teesside drone company DJM Aerial Solutions has recently invested in the industry-leading Flyability Elios 2, With huge success under their belts utilising the Elios 1 an investment made with help from both Digital City and Tees Valley Business Compass, The Northeast drone inspection company made the decision to upgrade their kit to the latest model.
The Elios range of UAS was developed around the requirement for confined space inspection and survey utilising none GPS technology and reliant only on the skill of the operator to carry out a pre-planned flight path to generate useable data for post review of dangerous confined spaces or hard to reach internal environments.
DJM Aerial Solutions invested in the Elios 1 in 2018 adding confined space inspection to their broad range of drone services. The financial assistance from both Digital City and Tees Valley Business Compass was key in securing the Elios without taking on any debts. The confined space inspection service has gained momentum over the last 2 years, really ramping up prior to lockdown with clients such as Heineken and Tarmac to name a few.
Elios 2 Point Cloud Company Director Dan Maine Added, “Our growing success utilising the Elios 1 for confined space inspection and survey of internal spaces was phenomenal, and it was a no brainer for us to upgrade our fleet to the next spec. Dan continued, “The Elios 2 has the ability to fly a preplanned mission allowing for photogrammetry outputs of that particular internal space, which we can then process into Point cloud or 3D models of the internal environment”
Internal Survey (s)
Internal survey and dilapidations are carried out generally using traditional manned access methods. Occasionally the properties can be come subject to vandalism or accidental damage from fires, water, rot, damp etc and are deemed structurally unsafe to enter on foot.
DJM Aerial Solutions areone of the few companies within the UK to own and operate the Elios an ideal solution to carry out these kind of surveys on dilapidated property or assets. However the Elios can also cope within an industrial environment too.
Confined spaces such as storage tanks and pressure vessels are to be inspected at regular intervals to comply with insurances and classification bodies. The process of carrying out vessel and tank inspections can be long and drawn out due to storage of toxic or harmful substances.
These storage tanks and vessels need to be fully cleaned of all or any potential harmful gasses prior to manned entry and even then pockets of gas may still be present. The Elios is obviously the ideal solution for confined space inspection as it can be carried out remotely without the need for any manned entry or confined space entry requirements.
Internal Point Cloud Survey
Teesside drone inspection company DJM Aerial Solutions has had numerous enquiries to provide internal point cloud solutions of confined spaces such as storage tanks, culverts, drainage tunnels and other internal environments and up until now there hasn't been a solution available.
The Elios 2 provides the solution to accurately fly a pre-planned flight mission utilising light-sensing technology to measure the distance from elevations and bulkheads allowing for sufficient overlapping photogrammetry methods.
The make up of the Elios 2 is such that the surrounding cage housing the UAS doesn’t cover up the UAS camera allowing full field of view unlike the Elios 1 which was limited due to the cage movement and its 4 axis gyroscopic technology. The Elios 2 cage is fixed however still allows the UAS to be fully protected from its surrounding environment.
