Version Auditing
Trace every timeline edit, stakeholder comment, and environmental metric shift across all project stages.
When regulatory submissions or stakeholder agreements hinge on precise timelines and performance baselines, accountability matters. 4d.io records every change to time-embedded scenarios—including who made it, when, and which metric changed as a result. If a timeline was shifted to accommodate community feedback, auditors can instantly see how solar shadow duration or vehicular delay metrics respond to that change.
Project managers use version auditing to isolate cause-and-effect relationships during compliance reviews. For example, if LEED energy performance drops, they can compare two versions side by side, highlight the exact adjustment to envelope or HVAC, and instantly see downstream effects on carbon estimates and utility loads. This supports faster root-cause analysis and defensible explanations during code or certification audits.
Legal and compliance teams appreciate the immutable metadata chain: timestamps, user roles, version comments, and linked annotations are preserved in exported files like IFC, CityJSON, and SDF. No external version control or spreadsheet tracking is needed—just export the full audit trail with the model, satisfying both internal governance and external review requirements seamlessly.
