Aerial Drone Roof Inspections & Surveys Gloucestershire

Welcome to Certified Drone Pilot. We are based in Gloucester, Gloucestershire and we provide aerial drone inspections and surveys, and regularly provide aerial inspections for commercial properties in Gloucester, to locate and photograph blocked guttering, and blocked air ventilation points on the tops of large roofs.

We are certified with a CAA PfCO (Permission for Commercial Operations), and we have a good understanding of UK air regulations, flight safety, flight planning as well as flight skills.

Drone pilots remotely operate drones for aerial surveys and inspections, video production and aerial photography. Some of our work involves aerial photography for property agents, aerial surveying and inspecting infrastructure, such as bridges and tall buildings, and mapping land use for farming or archaeological work. We do aerial roof inspections, for small commercial buildings, hotels, schools and large warehouses. We also provide aerial wind turbine blade inspection.

We provide a full pre-site assessment before we proceed, which we complete using a variety of ordinance survey maps, Google maps and UAV flight tools to get a better understanding of the local area of your post-code, assessing any risks and hazards which we need to be aware of. Once we can confirm a safe flight can be conducted, we can both agree on a time and day for the flight operation.

How much do you charge for Aerial Surveys?

We price our drone aerial surveys based on the size of the building as this better reflects the time to completion. We are very experienced, licensed and insured.

Pricing Examples

Small Commercial Building £250
Wind Turbine Blade Inspection £250
Medium Size Hotel £250
Large Commercial Roof £250
Medium Size School £250
Large Warehouse (50,000ft) £300

The footage and photography.

We use a Mavic Pro 2 with a Hasselblad that shoots at 20MP with 4K video recording. The 4k video recording uses the new h.265 codec, introducing stunning 10-bit video quality that we can colour grade to exactly how you like it. Furthermore, we are also videographers and can provide video footage on the ground and in your work environment too, so we can tell a better story of your company.

Aerial time-lapses and high quality drone photography can also be provided, as well as drone mapping, which is a revolutionary strategy of programming the drone to take multiple images in series to generate a very-high quality map for insight into the property details. This can then be passed to a licensed land surveyor, so that contour lines and accurate borders can even be overlaid onto the imagery.

Aerial Videography / Photography

We definitely have an eye for this business – since we produce professional videos for the defence sector, manufacturing, engineering, technical, production, logistics, sales, marketing, communication, training, corporate, Company profiles, tourism and sports.

We’re always interested in working on new projects and in new industries – we thrive on challenge and variety. Our videos can be and have been used for a variety of purposes including websites, social media, advertising and promotion.

Drone Aerial Photography for Real Estate

Elevate your marketing to potential buyers with a birds-eye view of your property, and stand out on Zoopla, Rightmove and Prime Location. It’s no secret that drone aerial photography will vastly increase the salability of your home or commercial property.

We provide aerial drone property photography and videos for residential estate agents, which can be a winning combination for selling your property. Because we have experience in video production, we can also provide ground-based video production along with your aerial footage.

Aerial photography and video can capture the scale of the property and its garden, which is not possible with conventional photography.

We have our own in-house editing studio using a powerhouse computer hardware and editing tools at our disposal. We offer professional editing services including, graphics, colour correction and grading services tailored to your requirements.

We can grade and adjust our aerial images and video footage to incorporate your corporate image or design, soundtrack, and even music to deliver film ready for publication. We can also advise and install videos on your website too.

Wind Farm / Turbine Aerial Survey

We specialise in high-resolution aerial drone inspections of wind-turbines, concentrating on the rotor blades, nacelle and tower. The benefits of working with us will provide you with competitive rates, a safe and professional working manner, and minimal downtime for the turbine itself. We can achieve a drone inspection for visual images on wind turbines for on-site analysis and assessment regarding the condition of the rotor blades and other parts.

Wind turbine towers are heavily eroded and damaged from weathering, and this can render the blades ineffective due to the reduced angle of attack. Since the blades are made of carbon fibre reinforced composites, they are very susceptible to wind, rain, hail and dust. Over time, the blade’s angle of attack is eroded, and the wind can no longer turn the rotor blades, and a wind turbine that isn’t working is costing money, and is a liability.

At current, wind turbine blades made from glass and carbon fibre composites are next to impossible to recycle, and are often cut into smaller pieces and disposed of in landfills. Up to 50,000 tonnes of rotor blade materials are expected to arrive in waste reception centres between now and 2020.

Aerial Inspection of a Wind Turbine

We’ll be focusing on the following key areas to ensure a safe flight and effective results;

  • A pre-site and an on-site assessment to ensure a safe flight
  • High quality images and video footage to help you assess the damage more carefully
  • Reduced downtime with a very short operational time for the inspection
  • Access to otherwise inaccessible areas
  • Preventative maintenance with seeing potential issues before they escalate

How can a drone / UAV survey help?

Traditionally, a three-man rope access team carried out wind turbine inspections. Experienced rope climbers descend from the nacelle to each blade from the turbine hub. The process is slow and intensive, and ofcourse risky for the team with regards to where general safety is concerned.

A UAV/Drone cannot completely replace methods, but it sure makes it easier to have preventative inspections, whilst done without putting men at risk. The risk exposure in a “working at height” situation is reduced greatly, all whilst being far more cost effective. Because of this, you can justify more frequent inspections, and meet the legal requirements to ensure the turbines are operating to a good standard.

 

Our methodology

  1. As stated earlier, we begin with a pre-flight assessment, checking ordinance survey maps, weather and meteorological data,  GPS coordinates and building a mission plan.
  2. Once we have this in place and we have agreed to the flight date and time, the equipment is set up. We use a Mavic Pro 2 drone which utilises a 20MP 1-inch Sony sensor, and this has fantastic resolution at 4K video with a 10-bit colour depth. We also use Sony A7III cameras for high resolution 4K footage for ground-level inspections.
  3. One the day of flight, insurance is paid for the time-slot and we’ll turn up on-site to prepare a short 5 minute assessment of the area, in order to double check we have the correct details about the area which were checked in the pre-site assessment.
  4. We’ll brief you before the flight, and carry out the procedure with your guidance, and your instructions on what footage you wish us to get, and where to concentrate our efforts.
  5. The footage will be delivered to you within 2 days.

Growing Change in the Trend of Energy Generation

There is something interesting going on with energy production, and it signals a growing change in the trend of energy generation.
According to the institute for energy economics the boost for renewable energy is due to a seasonal increase in low-cost solar and hydropower generation. This is alongside a slump in electricity demand of 3%; the slump has been caused by pandemic related reduce demand from commercial and industrial sectors.

As you’ll soon see, hydro generation is falling as well, so it’s wind and solar that are rapidly increasing. Amid the pandemic, U.S. renewable power sources have topped coal for 40 days in a row, with solar and wind meeting the demand. 40 straight days of renewable energy beating coal is very, very significant.

According to current financial analysis the percentage of coal in the EU power generation market is expected to collapse into single digits by 2025.
In 2014, coal supplied 38.6 percent of the nation’s energy supply, and by 2019 that figure dropped to 23.4. Coal demand is set to drop a whopping 20% this year while renewable energy generation will grow 11%. This 11% growth is due to grid operators favouring their lower operating costs. Natural gas prices are also dropping, compounding to move away from coal.

This story about renewables overtaking coal is as much about the collapse of coal as the rise of renewables. There have been many coal company bankruptcies as well as production over-capacity – this has all led to capital investment drying up.

Interestingly, according to IBS world statistics, the energy production of hydroelectricity is also falling due to more droughts. Hydro energy has fallen by 0.7% over the last 5 years, so solar and wind are making more of a difference in the renewable sector.

Energy Storage and Technology

We can now use utility-scale batteries to store the excess amount of energy, though when the sun isn’t shining and the wind isn’t blowing, these batteries can feedback the energy onto the grid; it’s very clear now that the potential for electric energy storage is huge, from electric cars and aircraft to utility storage. Over the last decade, a surge of lithium-ion battery production has led to an 85% decline in prices. This makes electric vehicles and energy storage commercially viable for the first time in history.
