Change Impact Agent

Agent

Quantify and communicate the ripple effects of design/spec changes fast. Compare model deltas, map impacts to sheets, scope, cost, and schedule, and publish an auditable change package for stakeholders.

(This tool is currently under construction — features may evolve.)
Inputs: RVT/IFC snapshots, addenda/bulletins (PDF), change logs Outputs: Impact report, QTO deltas, affected views/sheets Integrations: Revit, ACC Issues/Cost/Schedule, Navisworks Time to Value: 2–5 weeks

Example: Delta dashboard showing scope, cost, schedule, and drawing impacts from Bulletin 06.

Design Bulletins & Addenda

Compare before/after models and documents; summarize affected assemblies, rooms/zones, and disciplines.

Scope Creep Detection

Spot untracked increases in quantity or spec level (e.g., finish upgrades) and flag downstream cost/schedule effects.

Sheet & Revision Audit

List impacted sheets/views, revision clouds, keyed notes, and required re-issue sets for coordination partners.

Change Order Support

Create defensible QTO deltas with citations to model elements and spec clauses for commercial clarity.

1) Intake

Select baseline and revised RVT/IFC (or dated snapshots); attach bulletin/addendum PDFs and any change log notes.

2) Delta Detection

Compute adds/removes/edits at element/type/category levels; detect parameter changes (size, spec, material, phase).

3) Propagation Mapping

Trace impacts to sheets/views, schedules, keynotes, quantities, and dependent assemblies; identify affected rooms/zones.

4) Quantification

Produce QTO deltas by CSI/UniFormat; roll up by discipline, zone, and phase; estimate cost and time impacts (ranges).

5) Risk & Communication

Group by risk (constructability, procurement, schedule); draft RFIs/submittal updates and coordination tasks.

6) Output & Sync

Publish an impact report (PDF/Excel), annotate affected sheets/views, and sync issues/cost items to ACC.

Works With

Revit (models/views/schedules), IFC, ACC Docs/Issues/Cost/Schedule, Navisworks viewpoints, bulletin PDFs.

Deliverables

Delta QTO tables, affected sheet/view lists, issue register with priorities, cost/time impact summary, citations pack.

Rules & Thresholds

Set sensitivity for element changes, quantity variance thresholds, and zone/discipline weighting for prioritization.

Integrations

Hook into estimating (Sage/WinEst), scheduling (P6/MSP), and firm cost-code schemas for seamless rollups.

Reporting

Customize report columns, pivot layouts, naming tokens, and export templates for internal/external stakeholders.
