Court-Proof Your Construction Projects

On construction sites, there is a simple rule: If it isn't documented, it didn't happen. With Hamerly, every task, photo, and message is automatically documented. So when disputes arise, you always have a clear record of what happened on site.

Complete Project Audit Trail
Example
[2024-10-24 - 08:14] Photo captured (GPS verified)
[2024-10-24 - 08:15] Defect logged by J. Schmidt
[2024-10-24 - 09:02] Assigned to Subcontractor A
[2024-10-24 - 11:45] Site manager confirmed

Clear Evidence in Disputes

All entries are stored immutably and timestamped. If a subcontractor disputes a delay or a defect, you can clearly demonstrate:

  • who was informed
  • when a task was created
  • what photos and information were documented

Giving you reliable evidence for discussions or legal cases.

One-Click Bautagebuch PDF Export

Hamerly automatically generates a legally compliant Bautagebuch PDF directly from your live project data — one click, every day accounted for. Select a date range and download a complete, submission-ready document including:

  • Cover page with project name, address, responsible site management, and period
  • One section per day: weather, daily protocol, photos (2-column grid), working hours by company, tasks by status, issues, and sign-off
  • Full project ZIP with all photos, tasks, and communication logs

No manual formatting, no Word templates — everything already tracked in Hamerly is automatically compiled into a ready-to-submit document.

GDPR & DSG-Compliant Time Tracking

Bauleitung (the general contractor) can view working hours across all companies on a project — without ever seeing individual worker names. Only company-level totals are shown: company name, worker count, and net hours per day. This is compliant by architecture, not just policy:

  • Individual worker names, clock-in/out times, and approval history are only visible to the worker's own company
  • Bauleitung sees aggregated company totals only — a permanent privacy notice explains this in the app
  • Satisfies GDPR data minimisation and Swiss DSG requirements
  • Removes the legal and works-council objection that has blocked digital time tracking in DACH

The first site management platform where Bauleitung can track total hours by company without ever seeing a single worker's name — fully GDPR and DSG compliant by design.

"Since using Hamerly, we've successfully defended against 100% of unjustified delay claims. The data speaks for itself." — Legal Dept., Construction Company
