A Daunting Task – High Rise and Tower Block Inspection

A Daunting Task – High Rise and Tower Block Inspection

In the last five years, drones have been making their presence felt across the economic landscape from agriculture and architecture to environmental monitoring and supporting the emergency services.

They have been adopted so easily in so many markets because they are a fast, cost effective and safe alternative to traditional methods of working. And they have proven themselves to be effortlessly adaptable to any natural or built environment.

Wherever drones go next, and we’re sure it will be far and wide, one of the original uses for this technology was in building inspections, a use that is more pertinent than ever in the post-Grenfell landscape.

There is a huge challenge facing the UK Government and property managers up and down the country, to inspect and survey the nation’s high-rise residential buildings to ensure they are safe, secure and fit for purpose.

It’s a daunting task but one that can be tackled quickly, effectively and at a vastly reduced cost with the support of drone technology.

Let us show you how …

THE PROBLEM

The Grenfell Tower tragedy has exposed the vulnerability of thousands of blocks of flats up and down the country. That vulnerability lies almost entirely within the use of cladding that was applied to improve heating and energy efficiency and to improve the appearance of buildings, many of which had been constructed in the 60s and 70s.

CLADDING

While the use of cladding may have delivered on those needs, the Grenfell fire showed just how dangerous the use of certain types of cladding is. Every single block of flats in the country that has been cladded has to be surveyed and inspected to understand the risk profile of each one.

Which creates a huge challenge for the Government and property managers. An estimated 1,700 high rise blocks of flats have to be surveyed and the cladding removed to make them safe to live in. And they need to do it quickly.

TRADITIONAL METHODS

The Government has pledged billions to facilitate this nationwide structural survey but the Housing, Communities and Local Government Committee has estimated that as large as this fund is, it will only be enough to repair a third of the properties currently considered unsafe.

The reason? A huge chunk of that cost is because the traditional method of inspecting high rise buildings is to erect scaffolding around the structure, a process that takes months to complete and costs on average £250,000 per building.

Technology-Led Methods

But there is another way, a way that is led by, facilitated and completed by drone technology. A method that could reduce the cost of inspection by a factor of 100. Sound too good to be true? It’s not, it’s reality and we are helping clients across the country bring those theoretical savings to life.

THE SOLUTION

Like anything in life, there is no quickfire solution to the UK’s high-rise living problem. But with a little creative thinking and the smart application of technology, a real difference can be made to the way we approach it.

Which is exactly what Iprosurv has been doing with our property management clients.

WHY DRONES

Put simply, drones are a faster, cheaper and safer way to conduct surveys at height but their ability to provide the necessary data digitally, in a secure fashion, means that they can deliver a high-quality result in days, rather than the months the traditional method requires.

So what does a high rise drone inspection involve?

  • Our pilot will attend the site, secure it and be airborne within an hour
  • They will conduct a full survey using RGB – Optional Thermal Technology
  • Depending on the size or complexity of the structure, the flight and gathering of all the necessary data will be completed, on average, in 1 – 6 hours
  • The data is then shared with all relevant parties via Iprosurv’s proprietary, GDPR-compliant data delivery system
  • Clients receive the data in the form of a detailed, interactive 3D model of the building which can be analysed down to 5mm per pixel.
  • All of this is delivered for an average cost of a £2,500 compared to the average £250,000 cost for the traditional scaffolding approach
  • And there is no need to involve or disturb tenants beyond informing them of the flight taking place

INSPECTING YOUR BUILDING

While the drone does the hard work, our clients still have to bring their expertise to bear in analysing the drone data and planning the next steps. And we make that as simple or detailed as necessary with the creation of our interactive, 3D models.

3D MODEL

With the 3D model, delivered directly to their desktop, Iprosurv clients can:

  • Make detailed measurements of the building
  • Gain a full 360 view of the building
  • Annotate the model and the individual images of the site to share with others, assign tasks or share insight
  • Compare condition of the building pre and post-works
  • Create risk ratings on different aspects of the building
  • Share the data with other stakeholders with the click of a button, all fully secure and compliant with GDPR regulations
  • Access our proprietary software for ordering, case tracking and case delivery
  • Make detailed measurements of the building
  • Gain a full 360 view of the building
  • Annotate the model and the individual images of the site to share with others, assign tasks or share insight
  • Compare condition of the building pre and post-works
  • Create risk ratings on different aspects of the building
  • Share the data with other stakeholders with the click of a button, all fully secure and compliant with GDPR regulations
  • Access our proprietary software for ordering, case tracking and case delivery

A Case for Drones – In a Post Grenfell Landscape

The Grenfell disaster which claimed the lives of 72 people was not a one-off event, absorbed and grieved over before everyone moved on. The repercussions of that night are still with us and continue to be significant for residents of high-rise buildings across the country. And, indeed, for the landlords, housing associations and local authorities responsible for those properties.

The task facing the nation’s property managers is huge. They have to survey an estimated 1,700 high rise blocks, remove the cladding and make them safe to live in. And they need to do it quickly.

The Government has pledged £1.6bn towards these remediation efforts but it is a complex system, one that has come under attack for its perceived inaccessibility. But perhaps more pressing is the view held by the Housing, Communities & Local Government Committee that this £1.6bn will only be enough to repair a third of the properties currently considered unsafe.

Which presents a huge fiscal challenge for everyone involved, not least local authorities. 

It has been estimated by the same Committee that the cost of making each building safe will be £1.7m, covering everything from initial inspection, to the removal of cladding, to finishing the job. While it is clear that cutting corners or looking for cost savings in materials isn’t a viable option, there remains a pressing responsibility to keep costs down to make that fund stretch as far as is safely possible.

One part of the process where costs and timescales can be significantly reduced is in the inspection and survey of all these buildings through the use of drones. Not only can they do what a human can at a fraction of the cost, they can do it faster and with a greater degree of safety.

Drones are often viewed in extremes – either as a hobbyist’s toy or as a weapon of war. They are of course both, but increasingly, they are making their presence felt in the commercial world as more and more organisations wake up to their flexibility and adaptability. And one such area is the surveying of inaccessible properties.

Using High Resolution RGB imaging, drones can inspect the condition of a high-rise property (at a distance), in minute detail, in a fraction of the time it would take to do so manually using scaffolding, cherry pickers or ropes. The High Resolution RGB imaging is then translated into a 3D interactive model of the property which can be inspected in detail (up to 20mm) highlighting even the smallest amounts of damage to the outside and, when using thermal imaging, investigating anomalies such as damp ingress and thermal efficiency of the fabric of the building.

If LIDAR is incorporated increased levels of accuracy can be achieved down to 10mm and below.

The whole process, from instruction to inspecting the model, can take two or three days rather than the weeks and months required with traditional methods, and it is the speed with which drones can conduct surveys that should have landlords and local authorities sitting up and taking notice.

One of the problems facing property managers is understanding, in detail, the scope of the risk posed by their property portfolio and with the safety of tenants paramount, they need to understand it quickly.

Drones can help them do that as several inspections can be conducted in one day or over a period of days, providing the local authority with a quick, comprehensive view of their portfolio, including which properties pose the highest risk.

From here, the triage process begins, and drones are a speedy, cost-effective way of streamlining it, allowing the local authority to act quickly on its most vulnerable properties.

Drones can also act as a quality control tool to monitor and assess the ongoing work, and that governance role extends to post-work inspections to ensure the property has been re-instated as required.

If used properly, drones could and should act as the start and finish point of this remediation work and while they are not, of course, a catch-all solution for the many problems dogging the remediation programme, they do have a crucial role to play.

If the current remediation fund will not, as has been suggested, be sufficient to complete all the necessary work, then it is vital that any safe, reliable and proven cost-cutting measure be embraced as soon as possible.

In common with much of the commercial world, local authorities are at the early stages of exploring the possibilities presented by commercial drones. And in common with their private sector peers, it is those that recognise the opportunity earliest and act first, that will gain the most.

And that means giving tenants up and down the country quicker and more certain reassurance that they and their families are safe in their home.
