Desktop authoring stays primary
Teams continue doing the detailed controls work locally where schedules, narratives, and support files already live.
Collaboration
Built for real review cycles, not just file sharing.
ChangeSpan supports a practical team rhythm: do the heavy project controls work locally, publish what needs review, and bring the response back into the desktop workflow with less friction.
Portal review is structured
Published snapshots give reviewers a cleaner place to comment, approve, and respond without muddying the record.
Audit trail stays intact
Review events, revision history, and attachments stay tied to the same connected workflow instead of becoming scattered email threads.
