Mechanical completion, ready for commissioning, commissioning and system handover: each certificate checks the records beneath it before it can be raised.
A certificate is only as good as what sits under it. When the checks behind it live in different places, nobody can say for sure that a system is ready.
Sigma lists the check sheets, punch and earlier certificates each certificate needs.
Anything carried forward is justified, recorded and visible to everyone.
Signed in order by the people your project names, with the client's acceptance recorded.
The system's turnover dossier is built from the same records.
