Traditional Façade Inspection is Broken
Hong Kong's MBIS mandates cycle every 10 years, but the industry still relies on scaffolding, large crews, and paper-based reports — expensive, slow, and impossible to defend at audit.
Time
3 Weeks to Report
Sequential access across all elevations, manual data collation, and report drafting extending timelines well beyond what building owners expect.
3 Weeks
Audit Risk
No Reproducible Evidence
Paper-based findings cannot be independently re-derived. Regulatory defensibility depends on individual inspector recall — not deterministic data.
0 Replay
Coverage
Blind Zones on Every Building
Scaffolding access leaves setbacks, recesses, and high-relief cladding systematically under-inspected. Known gaps accepted as standard practice.
~23% Missed
SFSVC replaces the crew with a drone, the paper trail with a cryptographic audit chain, and 3 weeks with 1 day.
90%Cost Reduction
21×Faster Delivery
100%Coverage
Three Phases. One Day.
SFSVC collapses the traditional inspection workflow from weeks into a single structured field day, with automated report generation and sealed evidence packaging.
Drone Survey
Registered drone pilot conducts systematic façade capture — RGB, thermal, and LiDAR simultaneously. Full elevation coverage including setbacks, soffits, and parapet zones inaccessible by scaffolding.
~2–4 hours field time
NEPA Processing
Sensor streams feed into the NEPA runtime. Eight parallel processing lanes detect, classify, and geolocate defects in real time. Each finding anchored to a sensor frame, timestamp, and calibration certificate.
Automated · <2ms P95
Certified Report
Registered inspector reviews AI-classified findings, confirms risk banding, and countersigns the sealed audit package. MBIS-structured output ready for Buildings Department submission.
Same-day delivery
Defect Detection, Classified and Geolocated
NEPA's neuromorphic processing engine classifies façade defects by type, severity, and location — structured findings that slot directly into MBIS reporting templates.
Concrete Spalling & Delamination
Surface separation depth-estimated via thermal differential and LiDAR point deviation. Severity graded Low → High per MBIS CoP risk bands.
Crack Detection & Classification
Structural, shrinkage, and settlement cracks distinguished by width, orientation, and propagation pattern. Each crack logged with GPS-referenced polygon boundary.
Efflorescence & Water Ingress
Surface staining and active water infiltration zones identified via RGB and thermal channels. Correlated with building elevation and drainage topology.
Cladding & Tile Displacement
Hollow tile detection via acoustic correlation, surface displacement via LiDAR deviation. Priority flagging for immediate safety intervention.
Structured for Buildings Department Submission
SFSVC output maps directly to the Mandatory Building Inspection Scheme Code of Practice. Risk banding, defect classification, and report format aligned with MBIS inspection cycle requirements.

BAND IIISignificant defect — wide cracks, large delamination. Repair within 3 months.
BAND IIMinor defect — hairline cracks, surface staining. Monitor and repair within cycle.
BAND INo reportable defect. Routine maintenance only. No BD action required.
Every Finding is Attributable and Replayable
NEPA cryptographically binds each inspection run to its exact system configuration. Findings cannot exist without a traceable, tamper-evident configuration state.

01
Engine Version Hash
Every binary build fingerprinted before deployment. The exact engine version is locked into each run record — no drift between survey and report.
02
Configuration Contract Locking
Detection thresholds, lane weights, and fusion coefficients frozen at run-start and recorded verbatim. No mid-inspection parameter changes possible.
03
Sensor Calibration Certificate
Camera intrinsics, LiDAR extrinsics, and thermal offset records linked by UUID to each run. Every finding traces back to a specific, calibrated sensor state.
04
Operator Chain of Custody
Signed operator tokens bind every finding to an authenticated inspector session. Countersignature from registered inspector locks the package for BD submission.
05
Tamper-Evident Chain Sealing
Every system event enters a hash-linked chain. Each block references its predecessor, making retrospective modification detectable during any audit review.
Traditional vs. SFSVC
| Criteria | Traditional Method | SFSVC |
|---|---|---|
| Team Required | 6-person inspection crew + scaffolding team | 1 drone pilot + 1 registered inspector |
| Time to Report | 3 weeks average | Same day |
| Estimated Cost | HK$80,000+ | Significantly reduced |
| Façade Coverage | Partial — setbacks and recesses missed | Full coverage including inaccessible zones |
| Evidence Chain | Paper-based, non-reproducible | Cryptographic, replayable |
| Audit Defensibility | Inspector recall, subjective | Deterministic — byte-level replay |
| MBIS Output | Manual alignment to CoP | Structured CoP output, BD-ready |
