Marble Hall, Derby - 3D Drone Survey

Written by J.Jackson | Published:

Maintaining historic buildings requires regular inspections to identify signs of deterioration before they develop into more significant and costly repairs. For organisations responsible for managing public assets, obtaining accurate condition data while keeping disruption and costs to a minimum is an ongoing challenge.

Our Approach

The survey concentrated on all accessible external elements, including the roof coverings, parapets, gutters, chimney stacks and upper elevations. These are often the areas most vulnerable to weathering but also the most difficult and expensive to inspect using traditional access methods.

Our experienced survey team carefully planned the flight to achieve complete coverage of the building whilst maintaining safe operating procedures throughout. The entire survey was completed in approximately five hours, allowing the inspection to be carried out efficiently with minimal disruption to the surrounding city centre environment.

Once the site work had been completed, the captured imagery was processed over approximately eight hours to produce a detailed dataset for the client to review.

Because this forms part of Derby City Council's annual inspection programme, consistency is one of the most important aspects of the project. By following the same survey methodology each year and capturing imagery from comparable positions using the same professional drone platform, the client receives a dependable visual record that can be compared directly against previous surveys.

This approach allows even subtle changes in the building's condition to be identified quickly, providing valuable evidence to support proactive asset management and long-term maintenance planning.

How Did Our Client Benefit From a Drone Survey?

1. Lower Inspection Costs Without Compromising Quality

One of the primary reasons our client chose a drone survey was to reduce the costs associated with traditional building inspections.

Historic buildings often require scaffolding or specialist access equipment before roof inspections can even begin. These temporary access solutions are expensive to install and remove, particularly when inspections are carried out on a regular basis.

Drone surveys remove this requirement entirely.

2. Faster Surveys That Minimise Disruption

Efficiency is another significant advantage of drone technology.

The entire Marble Hall survey was completed in just 5 hours, allowing the inspection to take place within a single working day. Compared with traditional inspection methods, this represents a considerable saving in both time and disruption.

Because there is no need to erect scaffolding or restrict access around large sections of the building, normal activity within the surrounding area can continue with minimal interruption.

For buildings located within busy urban environments such as Derby city centre, this is particularly valuable. Reduced disruption benefits building users, pedestrians and neighbouring businesses whilst allowing inspections to be completed quickly and safely.

The speed of data capture also means maintenance teams receive accurate condition information sooner, enabling defects to be assessed and prioritised before they develop into more expensive issues.

3. Consistent Data for Long-Term Asset Management

Perhaps the greatest value of this annual drone survey lies in its consistency.

A single inspection provides an accurate snapshot of a building's condition. However, when inspections are repeated using the same methodology year after year, they become an invaluable asset management tool.

Extract from the 3D drone model

We follow a consistent survey process for every annual inspection, using the same equipment and capturing imagery from comparable viewpoints wherever possible. This produces a reliable visual history of Marble Hall that allows our client to identify changes with confidence.

Instead of relying on written observations or subjective comparisons, maintenance teams have access to clear photographic evidence showing exactly how the building has changed over time.

This supports better planning, more informed maintenance decisions and improved budget forecasting. Small defects can be monitored before they become major structural concerns, helping preserve the building while reducing the likelihood of unexpected repair costs.

For historic buildings where preventative maintenance is essential, having this level of reliable information allows property managers to make evidence-based decisions that protect both the building and public investment.

Why Choose SolidPoint?

Regular condition monitoring plays an essential role in preserving historic buildings, but traditional inspection methods are often costly, disruptive and time consuming.

By carrying out annual drone surveys of Marble Hall, SolidPoint has helped Derby City Council adopt a more efficient approach to building condition assessments. The survey provides detailed visual information across the entire exterior without the need for scaffolding, reducing inspection costs while improving safety and efficiency.
