Client: Housing 21
Project: External Condition Survey - 10 Storey Block

The Challenge

The client needed a full external condition survey of a 10-storey residential block in order to determine issues in the cladding and enable the planing of any remediation works.

Traditional inspection methods would have required scaffolding, specialist access teams, and weeks of disruption. The costs and risks associated with working at height were high, and results would take weeks to arrive.

• Time

• Cost

• Complexity

• Health & Safety

The Solution

DroneWorks used drone technology to capture high-resolution inspection data in just a few hours. The team collected 500 detailed images, covering all elevations and the roof. This data was processed into an interactive 3D model, hosted on a secure inspection platform.

• The project team and contractors accessed the 3D model online, improving context and awareness.

• Collaboration was easier - everyone worked from the same up-to-date data.

• CAD plans of the roof and elevations were produced for accurate reference.

The Results

• Speed: Survey completed in hours, not weeks.

• Safety: No scaffolding, no working at height.

• Clarity: Full scehdule of condition report hosted in an interactive 3D model, CAD Plans and images giving a full visual record - easy to review, share, and discuss.

• Efficiency:Detailed surveyor’s condition report prepared inside the platform. Issues were located, categorised, and reviewed quickly.

• Decision-Making:Building management could plan maintenance with clear evidence and prioritised issues.

One SIte Visit - Multiple Deliverables

The main aim was to enable a detailed condition assessment of the cladding. However, in the same single site visit, enough data was captured to enable the following deliverables:

• Detailed schedule of condition report (completed by our Chartered Surveyor)

• All issues are accurately located, categorised and priorised with suggestions for remediation.

• The owner can then decide which issues to focus on immediately and which to budget for in the next 12 months+.

• CAD Elevation & Roof Plans

• Interactive 3D Model

• view, share and collaborate with the team and contractors, from any internet enabled device.

• 500 High resolution images with full coverage of the block

• Georefernced point cloud - this enables measured surveys and BIM models if required

3D Model was delievred within days of the site visit and the surveyors report followed up 7-10 days later.

Why It Matters

For building managers, building surveyors, block management and facilities teams, this approach means less disruption, faster results, and better collaboration. Using technology to deliver a safer, smarter way to manage the building’s condition and maintenance planning whilst providing more detail and context to enable informed decision making.

DroneWorks are assiting with regular inspections of this block on a 6 monthly schedule enabling the management company to monitor defects and catch issues early, making it a better plaxce for the residents.
