COVID-19, a pandemic - has infected at least 2 million people all over the world and has caused almost approximately 170,000 deaths so far... In order to control and maintain the safety of populations, governments all over the world have implemented lockdowns. People have been restricted to their homes for more than a month (May 2020). Organizations, Governments, and societies need to think of better ways to can continue their operations with minimum physical contact.

Advanced technologies like GIS, Mapping, Data, Artificial Intelligence, surveillance cameras, and autonomous machines are playing a role in combating the pandemic. Drones are playing an active role in fighting this invisible menace. Governments and other authorities are using the drone technology to stop the further spread of COVID-19.

Let’s have a look at how drones are being used to carry on the essential life operations:

1. Grocery and Medicine Deliveries

Residential compounds and hospitals need daily supplies more than ever. Doctors are in need of medical kits and laboratory testing equipment to perform their operations. During all of this chaos, the need of the hour was to make use of a technology that can ensure minimum to no physical contact.

In this difficult time, drones are being used to fulfill the needs of the people. A lot of countries used drones as the fastest and the effective way to deliver groceries, supply medicines, and take samples from hospitals to laboratories.

On Feb 06, 2020, Wuhan, the epicenter of this pandemic, used an autonomous drone to deliver medical supplies and groceries. This drone also covered the areas where traditional delivery routes were closed.

see here for an example for drone deliveries:


2. Monitoring People’s Movement

An important responsibility of the authorities across the globe is to control the spread of this outbreak. Almost every country has banned mass gatherings and closed unnecessary public places to implement social distancing and limit person-to-person contact.

However, there are still some areas where people are not taking these measures seriously and not complying with the restrictions. That’s why law enforcement authorities like police are using drones to monitor the movement of people to break all types of social gatherings.

The drone based surveillance cameras are in use to ensure that people are safe and staying in their homes. This technology is greatly helping authorities to monitor a lot of areas at once without any kind of physical engagement, drones can cover distances easily and quickly, results are real-time.

3. Messages and Information Broadcast

Drones are performing the job of broadcasting information and sending messages or announcements especially to the rural areas that lack proper communication channels. China and several other European countries are using sky speakers with drones to spread messages of social distancing, wearing masks, taking necessary precautions, and staying indoors.

4. Spraying Disinfectant in Affected Areas

Health authorities are taking benefit of agricultural spray drones to spray disinfectant in the areas where COVID-19 is spreading fast. The spraying drones carry disinfectant in them and cover vast public spaces in less than an hour. Their speed and function is far better than the already-used traditional processes.

Drones are quite easy to operate and reach hard-to-access areas as well. They reduce the health risk by preventing health workers from being exposed to virus. Many countries like China, Indonesia, UAE, India, and Colombia have successfully used drones to disinfect their public areas. Spain was the first ever country that used agricultural drone for spraying disinfectant in public spaces.

5. Temperature Check through Thermal Cameras

During the peak of this virus in China, the health authorities used thermal cameras attached to drones to get remote temperature measurement in hard-to-reach areas. The operation was carried out on a large scale since people were highly worried about face-to-face contact and catching the infection.

6. Other Common Uses

The UK, United States, Germany, and China among others have used large empty spaces to construct temporary hospitals to treat more and more patients and lighten the pressure on hospitals. Authorities are using drones to survey these areas as well as a source of light to keep spaces illuminated. China used 6 lighting drones placed 50 meter above the ground to provide light to almost 6,500 square meter area. These drones provided light for 10 hours continuously with one charge!

As you can see from the evidence above drones are playing a larger part in everyday usage and imagination is only the limit for what they be used for in the future.

Property managers usually juggle with many different projects at once. They always look for ways to improve efficiency between their new as well as existing projects to save time and money.

Amidst all the latest advancements happening in the construction industry, drone technology is redefining the development, construction, and any construction process' for project managers.

Drones are great at transforming complex tasks. They are making the process of property maintenance easier and safer for construction professionals. A large number of professional project managers and building consultants are making use of UAVs or drones for maintaining their buildings and projects.

Here’s a list of some benefits that drones offer to project managers while simplifying the process of property maintenance:

Top 5 Benefits of Drones for Property Maintenance


1. Enable 3-D Modeling for Site Surveys

One of the most common applications of drone technology is its ability to conduct 3D scans of an existing property. Drones capture high-resolution photos that designers use to create a 3D point model. This 3D modeling of a building helps in getting exact measurements ranging from the vast parking lot to even the smallest window of a building. As drones provide accurate data about the existing condition of a building, it becomes easier to sketch a plan when you are looking for the renovation of a building.

2. Offer Aerial Photography for Roof Inspection

Property managers require aerial images for documenting the existing state of property for insurance purposes. These images are also used for the development of the property.

Aerial photographs make it possible to get a better overview of the property. The primary factor that counts in the long-term performance of a roofing system is the drainage system of the roof. The better the drainage, the longer the performance of the roof. Aerial imagery provides clear access to the overall drainage patterns of the roof. That’s why hiring a professional drone-savvy roof consultant is a cost-effective and quick solution for property managers.



3. Provide Aerial Infrared Services

Many building owners use infrared scanning services to access the roofing condition of their buildings. Infrared technology is very helpful in locating the trapped moisture within roofing systems. The infrared cameras in drones capture photos of the infrared energy patterns being emitted from the roofs. These photos help determine the trapped moisture in that particular location.

4. Make Property Marketing Easier

There’s no doubt that drones can capture images and videos unlike anything else. They can reach hard to access areas which humans can’t. Aerial pictures of a property are worth a lot when you talk about marketing and drones do that in a cost-effective manner.

Drones are revolutionizing the marketing practices for residential as well as commercial properties. They have completely altered the way property marketing industry because of their ability to acquire video footage from angles that are either not possible or expensive to capture. Such footages turn out to be a game-changer for marketing purposes.

5. Assist with Maintenance and Damage Assessment

Drones are not only useful during the construction or renovation of the building. They serve their purpose even after the construction phase is over. All the data captured by a drone can be used to plan long-term maintenance of the building. Besides that, drones can also help to access the damage caused by a tornado or a hurricane and make it easier for the owners to renovate and upgrade their assets for the future.

Aerial Drones for Property

Wrap Up

We cannot deny the importance of infrastructure because it is essential for economic growth, competitiveness, and social progress of a country. Almost all the historical and commercial buildings require some maintenance from time to time.

Building new infrastructures is great for the development of a country. However,  it is also important to keep an eye on the existing projects and provide adequate maintenance to them.

Using drones to find out and monitor property maintenance issues before the situation gets worse can help avoid costly replacements and repairs. The life cycle and worth of existing facilities can be lengthened by employing drones to make small improvements and delay new capital expenditures. You can save thousands, millions, or billions of dollars just by reducing exposure to safety risks.

Drones, also known as unnamed aerial vehicles (UAVs), are being used for military defence purposes and in tech-savvy equipment for quite some time. However, one of the main adopters of this exciting technology is the construction and surveying industry. Drones have transformed the entire construction industry and redefined the way buildings are projected, designed, and maintained. Drones can do much more than just taking high-quality photos. Let’s have a look at how drones add value and simplify the entire construction procedure these days:

drones in construction

Pre-Construction Activities

Drones help to understand the land distribution and terrain once you purchase the land. You can capture images with drones to get a better understanding of your investment.

Here’s how drones can help in construction projects before they even get started:

Analyzing Site Locations

A drone having geolocation abilities can provide clear connections between your land and the neighbouring locations in terms of distance and relative boundary points. This helps surveyors as well as project managers to develop more realistic expectations on timelines and design elements. They are better able to communicate with their clients about what is and is not possible. All such information can be collected before starting construction on a site to avoid later amendments and design improvements that lead to additional unplanned costs.

Creating Site Plans

The images and data captured through drones add value by creating layouts that offer information about how to create different segments of the location. Project managers build their whole site plan and drawings based on those photographs and distribute different elements such as parks, buildings, footpaths, and landscaped areas.

Performing 3D Scans

One of the great applications of drone technology is photogrammetry. This is about scanning the existing structure and creating 3D models from it. This is quite helpful in renovating buildings because it provides a detail-oriented model without implementing any conditions. Besides that, clients can get a better understanding of their space as well as the outcome of renovation before construction starts.

3D Point Clouds

During Construction

Drones are commonly used as survey tools in the construction industry to perform progress checks and increased supervision.

Drones in Construction

Aerial footage from drones add value to a developer's work in the following ways:

Post Construction

You can also make use of drones once the construction is completed.

Here’s how:

Maintenance and Damage Check

There are some construction companies that make use of drone footage in the surveillance and security of their projects. This footage serves as another level of time-stamped proof that can be shared with clients later for maintenance purposes or damage assessment of the building.

Drones are very beneficial in situations like:

Drone Survey


There is no technology better than drones to capture high-quality images or aerial shots. You can market your project or entire business by capturing real-looking photos of your place and running successful online marketing campaigns using them.

Final Words

For every project manager and builder, the surveying and designing phase of any construction project is hard to manage when it comes to timeline and cost. Planners and project managers have a lot on their plates in terms of monitoring the project, keeping everyone safe, and delivering their best for a certain period and budget. The traditional surveying methods are flawed and have certain limitations to them. They also take more time and require human labour.

However, drones can produce reliable data, track a wide range of areas, and inspect the ongoing progress efficiently and accurately. Besides that, they can do the job at a much lower cost as compared to traditional surveying methods. Moreover, they eliminate any risk to human life while working on a dangerous or difficult project.

The hospitality industry continues is always looking for innovation to improve customer services and increase the operations of its business. Considering the growing popularity and advantages of drones, this industry is now beginning to use drones to perform different tasks with a higher level of accuracy and efficiency. The versatility of drones has enabled hotels to develop products and services that would once have seemed impossible...

Drones are bringing new life to websites, giving customer service reps another tool to use for their emails and social media which always benefits from fresh content. Drones can deliver accurate results to data hungry customers whom are looking for those additional services that may entice them to staying at the resort.

How Drones are Upgrading the Hospitality Industry

The modern traveler is information hungry. They want as much data as possible before booking a hotel or resort for a holiday. You cannot fool a holiday shopper these days by only using flattering angles that make your building or pools look amazing from one angle alone.

Drone Surverys in the Hospitality Industry

Today’s traveler can search hotels with just a click and can view real-time images & views to before finalizing their holiday decisions. The more information you provide people to help them in their decision-making process, the greater are the chances to convert them into customers. Whenever there are gaps in the available information, people are more likely to skip to the next resort fearing the unpleasant consequences.

Advantages of Drones in the Hospitality Industry

Here’s how the hospitality industry is making use of drones at both hotels and resorts:

  1. Marketing with Aerial Photography

Modern hotels and resorts are benefitting with the use of aerial photography that has been taken with the help of drones. Using aerial photographs from a drone to showcase their hospitality location as well as the interior & exterior of the buildings to offer a clear images to their potential customers. They are also creating impressive video content from the drones to entice the audience so that they can book a stay at their resort or hotel.

  1. Drones for Room Service

Some hotels are using drones to carry out room service to guests in order to ensure that the food is delivered without any delays to their room. The drones can travel at a faster speeds compared to staff members delivering the room service. The technology may currently be a trend but can be here to stay due to the efficiency that it offers and its ability to impress guests!

  1. Mapping with Drones

Drones are used to create accurate maps that resorts can provide for their guests. These maps help guests in navigating the hotel and the outside of the building and local areas when moving around. This technology saves on staff time and improves on efficiency rather than having to provide directions to guests or guiding them to different areas on the ground.

Drone Surveys for the Hospitality Industry

  1. Drones for Surveillance

Drones make it possible view in 3D instead of a 2D frame. This helps security teams to monitor hotel buildings, parking lots, and other venues more carefully as well as cost-efficiently. This is more economical than hiring huge security-crew to sit in front of surveillance cameras 24/7.

Risks of Drones in the Hospitality Industry

  1. Data Theft

Industrial drones usually have simple computer architecture and they are not highly secure. Besides that, most of the data that a drone collects is unencrypted. Hackers can use standard debug tools to hack the data and can get an entryway into the company’s wireless network.

  1. Liability Due to Mishaps

Due to frequency interference or hacking system failure, a drone can loose control. This can result in a collision with another aircraft or can harm hotel staff or guests. That’s why any hotel or resort that uses a drone should carry liability insurance.

Drone Surveys for the Hospitality Industry

Final Words

Whenever a new technology is introduced, it always has its own share of risks and challenges. However, drones have proven their worth within a very short period of time by generating miraculous results in different industries. Technology this advanced is an art as much as it is a skill. Capturing aerial views and collecting useful data has never been this easy before the advent of drones. They are faster, more effective, more efficient, and capture a very compelling perspective.

What is the CAA National Drone Registration Scheme?

The Civil Aviation Authority (CAA), on November 5, 2019, has introduced a new National Drone Registration Scheme for drone users in the UK. Children and adults who want to fly a drone will now have to take the test to prove that they can do it legally and safely. The registration will become mandatory from November 30, 2019.

Why Do You Need to Register Your Drone?

There were growing concerns over safety after the increasing use of personal as well as commercial drones. Many airports, including Heathrow, had to suspend flights for several hours due to drone activity this year.

In December 2018, sightings caused 1000 flights to be reverted or canceled over 36 hours, affecting more than 140,000 passengers in the run-up to Christmas.

According to UK Airprox Board figures, in 2018, there were 125 near-misses between drones and aircraft reported. This number was 93 the previous year.

Because of all these incidents, CAA introduced a new law to regulate drone users as well as ensure the safety of people.


Who Needs to Register?

This scheme applies to anyone having a drone or unnamed aircraft such as a model plane weighing from 250g to 20kg.

Does the CAA National Law Include Both Commercial & Non-Commercial Drone Owners?

Yes. The UK Drone Registration Law includes all the professional as well as non-commercial drone users. You’ll have to pass an online test to make sure you are eligible to fly a drone.

drone surveys CAA

What is the Registration Process for CAA Drone Scheme?

If you are a drone user, visit to register your drone.

When you register, you’ll get an Operator ID with your certificate of registration. You must display this ID on your drone and model aircraft. Remember, you can use the same operator ID for all your drones and model aircraft.

UAV drone surveys CAA registration

Your Operator ID must be:

How Long Does It Take to Complete the Registration?

It takes around 20-30 minutes to complete the registration process depending on how much you need to learn and how much you already know. It covers the basics such as safety, privacy, and also some information on airspace.

What is Included in the Online Test?

The online test has 20 multiple choice questions and the passing marks are 16. You can take the test as many times as needed. The new Drone and Aircraft Model holds all the knowledge you need to pass the test.

Once you pass the test, you’ll get a flyer ID which will show your competency as a remote pilot from CAA.

The education package is free and you would need to do it every 3 years.

What is the Minimum Age for the Test?

There is an age limit of 18 for drone registration or to get Operator ID. Children under 13 will need a parent or other adult to register on their behalf and take legal responsibility.

How Much Does the CAA License Cost?

The process will cost £9 and you'll have to renew the license every year.

drone surveys uav

What Will Happen If You Don’t Register or Take the Test?

The deadline for registering your drone with CAA is November 30, 2019. As of December 1, 2019, anyone flying a drone without registration or without passing the test will be considered breaking the law. The maximum fine is £2,000.

How Will CAA National Drone Registration Scheme Help People in the Future?

The National Drone Scheme is a very helpful initiative to regulate the use of drones and unnamed crafts. The CAA's new platform will also help in returning lost drones to their owners. In case of losing a drone, you are advised to post their details on the Drones Reunited platform while anyone who finds one is encouraged to check if the drone has a registration number and enter the details online.

Wrap Up

This was all about the new CAA law for registering drones in the UK. If you have any queries related to this topic, feel free to contact HeliDrone Surveys. You may also ask your questions in the comments.

What is the Dilapidation Survey?

The dilapidation survey records the current condition of a property before starting any kind of construction or development work. It identifies all the structural defects that are present in the property prior to starting any major work.

Who Conducts Dilapidation Surveys?

Registered Building Inspectors who also do independent property inspections conduct the dilapidation survey. Their extensive knowledge, as well as experience of different construction types, enable them to record the parts of the property that are at higher risk of damage.

Which Types of Buildings are Inspected in This Survey?

The buildings that are inspected in the dilapidation survey majorly include landscape areas, commercial & residential buildings, and municipal infrastructure.

What is Recorded in the Dilapidation Report?

All the internal, as well as external walls and floor cracks including ceiling cracks, floor & wall tiling, retaining walls, external roofs, masonry fences, roadways, and channeling, are recorded in the dilapidation survey.

The depth of the dilapidation report entirely depends on the size of the project under inspection. Projects having large infrastructures like tunnels, pipelines, roads usually have a dilapidation report consisting of thousands of properties.

dilapidation report and drones

Why Dilapidation Survey is Essential

Building construction, infrastructure projects, road works, high-end development, and demolitions can sometimes lead to defects in the adjoining structure if proper precautions are not undertaken. This resulting damage creates situations where it becomes difficult to prove how it occurred and who is responsible for it.

The dilapidation report protects the property owner as well as the builder. It includes all the potential disputes regarding the condition of the property to avoid any inconvenience in the event if the property suffers any damage subsequent to nearby work.

How Drones Can Help in the Dilapidation Survey

The traditional methods of property inspection have several challenges associated with them. These methods involve high cost, a long time, and great risk. That is why construction companies are now looking for advanced methods to improve the quality and ease of their survey.

Drone-based inspections have come forward as a new paradigm in the construction and development industry because they have significantly improved the efficiency and data acquisition quality parallel to increasing speed as well as safety.

Drones are being used to inspect a wide variety of assets like aerial photography, surveying, deliveries, and asset inspection, etc. They produce detailed and accurate inspection data and minimize the mistakes that generate human errors.

dilapidation report 3

Benefits of Drone Inspection in the Dilapidation Survey

  1. In-depth and Detailed Insight

The advanced technology in drones can easily navigate close structures for capturing minute details. They can take high-resolution images that clearly show damage, cracks, misplaced wires, and other defects at angles that humans cannot see. This allows inspection teams to collect more detailed and comprehensive data.

  1. Minimize Danger and Health Risks

Drones make it easy to inspect tall and complex buildings such as pipelines, oil refineries, and flare stakes, etc. They can reach hard-to-reach areas where humans cannot reach. Drones eliminate the need for physically accessing dangerous locations where height, wind, and weather can lead to serious accidents as well as health risks.

dilapidation report

  1. Ability to Suit Different Inspection Needs

Drones hold the ability to inspect high or low altitudes. They come in several different sizes offering a wide variety to suit the right tools according to inspection needs. This is highly useful for rooftop inspections and building developers.

  1. Easily Shareable Data

Drones can capture images, make videos, produce thermal images, transmit data and can perform other advanced functions that enable them to collect and share the information which may take several months using conventional methods. Furthermore, you can easily share all the standard reports and analytical data across different sectors. Different industries can customize the information in different ways for interpreting and sharing relevant data.

  1. Save Money and Time

Drones reduce the cost and time required to access towers, use aerial lifts, erect ladders, set up stages, and other heavy tools. In addition, they can perform in-depth analysis and detailed surveys without even demanding humans to be present at the location physically. Drones can cover more area in less time thus saving both time and money.

dilapidation report 1.JPG

Wrap Up

Using drones for performing a dilapidation survey offers many benefits that are less risky, less expensive, and less time-consuming. Thus, drones are gradually replacing the traditional methods of conducting surveys that are more likely to produce inaccurate data and human errors.

The UK Drone Laws surrounding drones has always been a little challenging to understand for beginners. Particularly when it comes to what is allowed and what isn’t. Flying below 400 feet and not going within 50 metres of people and private property are just the beginning. When it comes to drone laws...

UK Drone Laws

For experienced operators, particularly those that use drones for work. There’s a continual wait for the government to publish their latest updates. 

New, additional legislation introduced in March 2019 has tighten the law, especially in respect of flying drones near airports. This includes registering devices that are over a certain weight and size.

The growing popularity of drones is all well and good but it doesn’t come without challenges. The mysterious drones that managed to close Gatwick and Heathrow airports last year only serves to remind us that legislation relating. To these devices is still in development and more is yet to come. UK Drone Laws

The current consultation has been going on for some while and the UK is not the only country. That is struggling to get the balance right when it comes to drone law. We already have a number of legal requirements that means drones can’t flow in popular areas such as towns and cities. Without permission while there’s also the prickly issue of public privacy when it comes to drone cameras. 

If you are using drones in your businesses, the March 2019 changes may create problems. Especially if you have to work within the exclusion area surrounding airports. And, if you aren’t sure where your nearest airfield is. You may unwittingly start flying a drone and open yourself up to prosecution. 

What Are The UK Drone Laws Changes?

Any pilot of a drone will now have to make sure they stay outside a 5km perimeter surrounding an airport, an increase from the previous 1km. This includes a 5km by 1 km extension covering the ends and beginnings of runways to protect planes taking off and landing. 

From the 30th November 2019, if you operate a drone that has a weight between 250g and 25Kg. You will need to undertake an online safety test and register with the Civil Aviation Authority before you are allowed to operate it. If you fail to do this after the start date, you could be liable to a fine of up to £1,000 if you are caught. 

UK Drone Laws

The police will have their powers extended from November 2019. This comes mostly in light of drone interference associated with airports but is also related to the potential for criminal activity such as flying drugs and other contraband into prisons. 

If a drone is thought to have been used in an offence. The police can obtain a warrant to search your property for evidence. They can also now give on the spot fines. If you have committed a minor offence such keeping the drone in Visual Line of Sight (VLOS) or refusing to land a drone when asked to do so.

Experienced drone operator

If you are already an experienced drone operator, you’ll have expected these changes and won’t surpris at the new additions to the law. Most understand that flying too close to an airport can be dangerous to flights. Just be aware that the perimeter has now been increased quite considerably. 

Registration and taking the online safety test may give rise to some issues. Neither of these are up and running yet though the CAA says everything will be available by the end of October 2019. How effective this will be remains to be seen. 

UK Drone Laws

The Future of Drone Legislation

This is almost definitely not the end of drone legislation in the UK or across the rest of the world. For instance, it seems likely that an age restriction will come in at some point. There’s also talk of developing an app for professional drone users so that they can keep authorities informed of where they are flying and when. 

There’s no doubt that the use of drones has increased dramatically over the last few years. They are utilis film companies, tourist boards, surveyors. The agriculture industry and even for delivering packages through companies like Amazon. The scope is set to widen as drones become increasingly sophisticated. 

UK Drone Laws

All legislation being introduced has to strike a fine balance between making users. Particularly in respect of commercial drones, more accountable while not impeding their operation. It’s a difficult compromise to achieve and may take a few years yet before it’s fully fleshed out. For drone users, it’s a question of keeping up to date with the latest changes and adjusting behaviour accordingly.

Case study 2

Brief Case study 2: Photograph and video roof survey of Kingston Hospital, Regency Wing

The Regency wing of Case study 2 Kingston Hospital was built in the 1800s as such the roof requires constant maintenance. Our client direct us to find out the condition of the roof examining the chimney stacks, the pitch and elevation. Ridge tiles, pointing, guttering and general overall condition. Pretty much standard variables in most UAV inspections we complete.
Case study 2 Case study 2 Case study 2

The Survey:

As the area was very sensitive (an operational hospital) with public moving around the site we were directed to the project manager on site. After signing in and completing various administration tasks. Sometimes we are required to provide a H+ S report and operational manual, insurance etc...). We were shown the landing and take off site.  This was well away from the general public and had restricted access. So we were confident that there would be minimal public traffic on site.

The Procedure:

When surveying an area of this building size it is important to find the correct starting and finishing locations in order to proceed in a logical manner around the building. It saves duplication the survey areas. As such we started on the west side of the building with the sun on our backs.  As it was a very clear blue sky day (10mph max wind) we were working in a very contrast environment.
This has particular challenges especially in shadow areas, away from direct sunlight.  Here we must either use auto shutter and ISO settings or manually select them ourselves so that the client will see as much detail of the roof as possible.  Moving around the roof area we concentrate the camera on various inaccessible locations taking care to zoom in on any particular details we feel the surveyor may interest in.  There are generally all sorts of debris and maintenace issues. From plant growth to leaking gutters. Rendering damage to slates missing and pointing issues. Notice the chimney stacks and there overall condition.
Case study 2 Case study 2 Case study 2
Sometimes we don't have any representation from the client (we just get a brief). So we need to make sure we cover all details from every angle so that the surveyors report covers is comprehensive. As the building is so large it takes several batteries to complete the UAV survey and as per usual once we had finished. The sun went in! Overcast days are so much easier for completing photography as you do not encounter such high contrast images.

Case study 2 - Kingston Hospital

Once all stills photography was complete we continued with the video survey.  This is conduct in a 4K resolution as specify the client. The great thing is the the 4k video is almost as good as the stills and the surveys can often see even more detail. They can even get stills from the video to high light to their client any more signs of wear and tear.

Case study 2 Case study 2

The Conclusion:

As mentioned, this was quite a challenging environment in such a public space. During the course of the survey we had encounters with not only the general public. But also hospital management, concern  with privacy of the patients and noise. We had to reassure that no photographs were taken of individuals and we were only concern with the roof structure. Privacy is of paramount importance and we respect all private locations.

Case Study 1, Drone Survey Case Study 1, Drone Survey, London


For Helidrone this was an unusual type of property survey to undertake Case Study 1. For a start, the location was fairly unusual being in London, Case Study 1 right on top of the Thames. The location itself was not in any highly restricted flying zone - Class D. However when we contacted NATS they informed us that not stray into R158. This was quite a clear borderline as crossing it meant flying over Tower Bridge and heading along Thames west and into the area of City hall, a high-security zone!

Case Study 1

THE TASK Case Study 1

The task was to photograph and video the roof area and front side of the property which would be hard to see without the use of the drone. This is one of the great flexibilities of using a UAV. Getting access to all those inaccessible locations. How else could you get a good view from the riverside in close up detail of this location? Especially the roof area, which was not straight forward pitched roof. It comprised of various levels and details that could only be seen from acute and birds eye angles that the only a drone can fly to. There where several areas that needed attention such as gutters, pitches and flat roof areas that the on-site surveyor needs more detail of for his report writing to the potential new buyer...

Case Study 1 Case Study 1 Case Study 1

One notable situation was choosing the take-off and landing zones. This area is required to be safe enough to use (with the crew in the vicinity) and as most of the locations that were suitable on the site were surrounded by metal railing and fences there was an issue with recalibrating the compass. Something I always try to do at each location. However with perseverance. We achieved this at the end achieved as well as getting GPS reception, so we were safe to fly.

With the surveyor checking the monitor from the camera feed. We were able to achieve all the desired locations for him to write his final report, job did take a look at our other case studies:

Case Study 1 Case Study 1 Case Study 1


Drone regulations flying are highly regulated in the UK and there are laws and guidelines in place. The new legislation is due to take effect in 2019. Some drone laws have been in place since 2017. These amend the existing air navigation order of 2016.

UAV operators in the UK are ban from exceeding 400 feet at and from using a drone within a radius of 1 kilometer of an airport. Contravention of this law can mean unlimited fines and up to five years in prison. 

Department of Transport Regulations

Moreover, in 2018 the Department of Transport implemented new rules whereby if drones run to over 250 grams in weight. Drone pilots are required to register their drones with the CAA and pass a series of exams and practical tests in order to operate safely and legally. This is known as the PfCO, Permission for Commercial Operations. Those who fail to register and pass the exams may fine up to £1000 for commercially using drones. The new laws form part of the government's new industrial strategy and aim to plan for the expansion of drone use throughout the UK. Some exemptions for some UK airports may deem necessary and further information on this is still to confirm. The new drone bill features several new laws that are due to come into effect but have not yet announce. 

To minimize the impact on model aircraft associations the government is a point to examples of the positive use of drones. For example, to inspect Hinckley's point nuclear power station, hospitals and public buildings. In other examples drones are also used to reduce costs of wind turbine inspections 50%. So, the potential for drone use within industry and business is only starting to realize. It is estimate PwC that uptake in the use of drones could add over £1 billion to the UK economy in the next 15 years. So drone regulation is important and is forcing the industry to become much more professional. 

Increased safety in drone use

Department of Transport expects the new rules to increase safety when protecting the public whilst also ensuring the increase benefits of drones within the industry. Regulations now cover remote operators of drones as well as a pilot in charge, or SUA operator. Existing regulations require commercial drone pilots to update their operations manual with appropriate information. Any applications or renewals which are not update will cancel.
