At handover, one package holds every register, check sheet, certificate, change, transmittal, form, file and photo, with the full audit trail. It opens in any web browser without Sigma.
Handover dossiers are built in a rush. Weeks of copying, printing and chasing signatures, at the exact moment the team is being demobilised.
The package is built from the project's own records, not collected by hand.
Anything missing or unsigned is listed before the package is issued.
The client's acceptance is recorded with a signed receipt.
Keep the project locked for seven years, or erase every record. The client chooses.
