Services

Services.

01

Aerial Photogrammetry

3D mesh models and orthomosaics from overlapping aerial imagery. Ideal for site documentation and volume calculations.

✓ 2cm GSD
✓ RGB mesh + texture
✓ Orthomosaic export
✓ Volume cut/fill
02

Façade Inspection

High-resolution capture of building façades and hard-to-access elevations. Safer than rope access or MEWP.

✓ Sub-cm imagery
✓ Defect mapping
✓ Annotated reports
✓ CAA PfCO operated
03

Drone Thermography

Radiometric thermal imaging from UAV for roofs, building envelopes, and solar installations.

✓ Radiometric TIFF
✓ FLIR Duo Pro R
✓ Heat-loss mapping
✓ Post-processed
04

Progress Monitoring

Scheduled overflights throughout construction to track progress against programme and document as-builts.

✓ Weekly/monthly cadence
✓ 4D comparison
✓ Time-lapse archive
✓ Cloud delivery

Use Cases

What we're flown for.

Roof condition surveys

Full roof inspection without scaffolding or MEWP hire. High-resolution imagery with annotated defect reports.

Façade & high-rise inspection

Sub-centimetre imagery of elevations for condition surveys, cladding assessments, and remediation planning.

Solar PV — feasibility & inspection

Pre-install roof measurement and shading analysis; post-install thermal inspection to find failing panels.

Earthworks & stockpile volumes

Cut/fill and stockpile quantities from photogrammetry — repeatable monthly for valuation certainty.

Construction progress

Scheduled overflights that give the whole project team a dated visual record, comparable month to month.

Planning & site context

Orthomosaics and 3D context models for planning applications, design studies, and stakeholder consultation.

FAQ

Common questions.

Are you CAA-approved? +
Yes. We hold current CAA Operational Authorisation and A2 Certificate of Competency. Every flight operates under a documented Operations Manual with pre-flight site assessments.
Can you fly in urban areas? +
Yes, under the appropriate flight category. We handle all permissions, NOTAMs, and coordination with local stakeholders. Restricted airspace (near airports, prisons, military) requires additional lead time.
What weather do you need? +
Wind under 12 m/s, visibility above 5km, and no precipitation. Thermal work is best at dawn or dusk for maximum thermal contrast. We schedule weather windows and reschedule at no cost if conditions fail.
How is the data delivered? +
Orthomosaics and 3D models via secure cloud share, typically within 5 working days. Raw imagery available on request. All data is backed up and retained for 12 months.
