SAC Accredited Inspection Company Singapore — Quality Assurance Guide
Published 15 April 2026 · SG Drone Inspections
SAC Accredited Inspection Company Singapore
Selecting the right drone inspection company in Singapore requires verification of credentials, capabilities, and track record. This guide helps building owners, MCSTs, and facility managers evaluate providers effectively.
The quality difference between providers is significant. Choosing poorly can result in BCA rejection, invalid data, and legal liability from unlicensed operations.
Essential Verification Steps
CAAS Licensing
Verify all pilots hold valid UAPL licences. Request licence numbers and expiry dates. Non-negotiable for legal commercial operations.
Aircraft Registration
All drones must be registered with CAAS. The registration number should be visible on the aircraft.
Insurance Coverage
Request third-party liability insurance certificate. Verify coverage amount and validity dates.
Sample Reports
Review previous inspection reports for quality, compliance, and completeness. The report is the deliverable you are paying for.
References
Ask for references from similar projects — same building type, height, and inspection purpose.
Quality Indicators
Enterprise Equipment
Professional companies use DJI Matrice or equivalent enterprise-grade platforms, not consumer drones like DJI Mini.
TR 78 Compliance
For facade inspections, the company should provide TR 78 compliant reports as standard with compliance statements.
PE Relationships
Established relationships with registered Professional Engineers demonstrate experience with BCA submission processes.
Structured Methodology
Documented inspection procedures, flight planning standards, and quality management processes indicate professional operations.
Red Flags
- Cannot Produce UAPL — immediate disqualification. Operating without a licence is illegal.
- No Activity Permits — flying without CAAS permits is a criminal offence. Do not allow unpermitted flights at your building.
- Consumer Equipment — DJI Mini, Mavic, or similar consumer drones are not suitable for professional inspection.
- No Sample Reports — inability to show previous work suggests the provider lacks experience or produces poor quality documentation.
- Unusually Low Pricing — very low prices may indicate unlicensed operations, consumer equipment, or inadequate reporting.

Frequently Asked Questions
Evaluating Technical Capability
Beyond basic credentials, the technical capability of a drone inspection company determines the quality and usefulness of the data you receive. Here is what to assess.
Equipment Quality
Enterprise-grade drones (DJI Matrice series, Flyability Elios) deliver significantly better data than consumer drones. Ask what specific platforms and sensors the company uses. Camera resolution, thermal sensor specifications, and positioning accuracy all matter.
Analysis Capability
Data capture is only half the job. The inspection company must have qualified engineers who can identify, classify, and assess defects from the captured imagery. Ask about the qualifications and experience of their analysis team.
Report Quality
The report is what you pay for — not the flight. Ask for sample reports and assess them critically. Are defects clearly identified with annotated photographs? Is there a structured defect register? Are severity classifications consistent? Is the format suitable for PE review?
Airspace Experience
Singapore's complex airspace requires experienced CAAS permit management. A company with a track record of successful permit applications in your area can navigate restrictions that less experienced operators may not handle effectively.
Contract and Service Considerations
Beyond technical evaluation, practical service aspects affect your experience and the value you receive from the inspection.
- Fixed Pricing — the quote should be all-inclusive with no hidden costs for permits, mobilisation, thermal imaging, or reporting. Ask explicitly what is and is not included.
- Turnaround Time — understand the timeline from engagement to report delivery. Include CAAS permit processing (2-4 weeks), on-site inspection (1-2 days), and report compilation (3-5 days) in your planning.
- Liability Coverage — verify the insurance coverage amount and scope. Ensure it covers potential damage to your building and third-party liability during the inspection.
- Data Ownership — clarify who owns the inspection data and images. You should retain full rights to all data captured at your property for your records and future use.
- Post-Delivery Support — ask whether the company provides support after report delivery. Can you call to discuss findings? Will they brief your PE on the methodology and data? Is there a charge for follow-up questions?
- Repeat Inspection Capability — for buildings requiring periodic inspections, a provider who maintains your inspection history can produce comparative reports showing defect progression across cycles.
Questions for Your Shortlisted Providers
Once you have verified basic credentials, use these questions to differentiate between qualified providers.
How many inspections of this building type have you completed?
Experience with your specific building type — HDB, condominium, commercial tower, industrial facility — matters more than total inspection count. Each type has unique challenges.
Can I speak to a previous client with a similar building?
A confident provider will connect you with references. Ask the reference about report quality, turnaround time, communication, and whether the report was accepted by their PE and BCA.
What is your CAAS permit success rate for this area?
Experienced operators know the specific requirements for different Singapore airspace zones. A high success rate indicates thorough preparation and established CAAS relationships.
How do you handle defects you cannot definitively classify from drone data?
Honest providers acknowledge limitations. The best response is: they flag uncertain defects for follow-up investigation with recommended methods (rope access for sounding, core sampling, etc.).
