NFC-powered construction component verification system. Cryptographic proof that the right component is in the right place, installed the right way, at the right time.
Thousands of components, dozens of trucks, hundreds of workers — and no reliable way to prove the right piece is in the right place.
A single misplaced steel beam can halt an entire floor's work. Hours lost to phone calls and spreadsheets tracking components across yards, trucks, and sites.
A beam installed in the wrong orientation or grid reference may not be discovered until structural inspection — rework costs 5–10× the original installation.
Paper checklists get lost, signatures get questioned. When disputes arise, there is no auditable digital record of who verified what, when, and in what condition.
Tight schedules create incentive to skip pre-installation checks. Without enforced digital workflow, components get installed without proper verification.
In global supply chains, there's real risk of unauthorized substitution. Without cryptographic identity, there's no way to verify authenticity at installation.
Construction sites have poor signal coverage. Systems that depend on constant connectivity fail exactly where they're needed most.
Every component flows through six verified stages. Each transition requires an NFC scan — validated, recorded, and auditable. The system enforces order: no skipping allowed.
Every scan triggers a cascade of engineering-driven checks. Each layer validates a different aspect of installation correctness.
Confirms the scanned tag belongs to a valid component that is assigned to the current installation plan. Rejects unknown, unbound, or foreign tags immediately.
BLOCK on failVerifies the component's target installation zone matches the installation plan's zone. Prevents components from being installed in the wrong area of the building.
BLOCK on failValidates the installation direction (N1→N2) matches the engineering-specified direction in the Erection Plan. Prevents beams from being installed backwards.
BLOCK on failChecks prerequisite components are installed before the current one. Ensures structural stability during the erection process by enforcing the engineer's planned sequence.
WARN on Pre-Check / BLOCK on InstallFrom factory floor to rooftop steel — engineered for the environments and workflows that construction demands.
Standard Android phones become precision verification tools. Hold your phone near the tag — verification happens in milliseconds. No special hardware required.
Plans and data cached locally. Scans queued when offline, auto-synced when connectivity returns. Works in basements, tunnels, and remote sites.
4-layer NFC verification with encrypted payload. Only ACCUZ® encoded tags are accepted. Third-party, counterfeit, or cloned tags are automatically rejected.
Web-based admin console with live status pipeline, installation progress tracking, and real-time activity feed. Every scan visible within seconds.
Erection Plans define sequence, orientation, and prerequisites. Installation Plans translate engineering authority into field-executable work packages.
Every event recorded with operator ID, timestamp, GPS, NFC UID, and verification result. Tamper-proof digital chain of custody for regulatory and contractual compliance.
Powered by NFC construction verification technology, our cloud-hosted backend, web admin console, and mobile app work seamlessly together for enterprise deployment.
