Why Report Standards Matter
A drone inspection is only as valuable as its report. The most advanced drone produces nothing useful if data is not captured, analysed, and documented according to recognised standards. In Singapore, reports are used for BCA compliance, insurance claims, maintenance planning, and legal documentation.
Standards ensure consistency — the same defect described the same way regardless of inspector. They ensure completeness — every required data point captured. And usability — PEs, facility managers, and contractors can immediately act on findings.
Our reports follow TR 78 for facade inspections and ISO-aligned processes for industrial inspections. Every report undergoes internal quality review before delivery.
Standards by Inspection Type
| Type | Standard | Key Requirements |
|---|---|---|
| Facade (PFI) | BCA TR 78 | Systematic coverage, min GSD, defect taxonomy, PE format |
| Roof | ISO 6781 / 17020 | Waterproofing assessment, thermal standards, defect mapping |
| Industrial | API 510/570/653 | Corrosion mapping, thickness indication, condition grading |
| Confined Space | WSH / ISO 17020 | Internal surface documentation, structural assessment |
| Thermal Survey | ISO 6781 / 18434 | Calibrated data, emissivity settings, environmental corrections |

Frequently Asked Questions
How Drone Imagery Becomes Evidence a Competent Person Can Sign
A drone survey only has value in a PFI if the Competent Person can rely on it. BCA circular APPBCA-2025-09 sets out what that means in practice: images used for the inspection must be at a resolution of 0.15 cm per pixel or finer, supplied as standard .jpg or .png files, and left free of annotation so the CP sees the facade as captured. The CP must review the images personally rather than relying on someone else's summary.
Meeting that standard starts before take-off. Stand-off distance, lens choice and overlap have to be planned per elevation so that every image meets the resolution threshold, and each frame needs to be traceable to a location on the building. Without that traceability, a defect seen in an image cannot be found again on site for close-up checks or repair.
A good report standard therefore separates two things: the unaltered image set handed to the CP, and the marked-up defect schedule built afterwards. Keeping them apart protects the integrity of the evidence while still giving contractors a usable repair list. Read how we plan capture for a drone facade inspection.
