Construction Monitoring: Document Progress with Certified Photos

Construction disputes are among the most frequent and costly legal conflicts. Contested defects, undocumented delays, non-compliant work: in most cases, the outcome depends on the quality of evidence presented.

The problem with traditional site monitoring

Most construction professionals document their sites with smartphone photos. But these photos have several problems:

• No certified date: impossible to prove when the photo was taken
• No reliable location: GPS can be disabled or modified
• Easily challenged: the contractor or client can claim the photo is from a different period
• No traceability: who took the photo? With which device?

Certified monitoring: step-by-step evidence

With Truth-Check, every construction site photo becomes timestamped, geolocated, and cryptographically verifiable evidence:

• Before work begins: document the initial state of the site
• During construction: certify each key milestone (foundations, structure, finishing)
• After completion: prove delivery compliance
• For defects: document issues with irrefutable evidence

Who benefits from certified monitoring

Project owners and homeowners

Building or renovating? Certified photos protect you in case of defects or non-compliance. If the contractor disputes, you have dated and geolocated proof of the work's condition.

Contractors and construction companies

Protect yourself against abusive claims. If a client claims work wasn't done correctly, your certified photos prove otherwise.

Architects and project managers

Document progress for your monitoring reports. Certificates can be shared directly with stakeholders via a simple link.

A minimal investment

Certification costs are negligible compared to the financial stakes of a construction project. With a Pro subscription at 9.99 EUR/month, you get 50 certificates monthly — more than enough to document multiple simultaneous projects.

By comparison, a court expert costs several thousand euros and intervenes after the fact. Preventive certification is always more effective and less expensive than conflict resolution.
