4D Agent

Agent

Link models to schedules, generate time-phased sequences, and surface clashes between logistics, access, and trade work. Review alternatives and publish animations and look-ahead views with one click.

(This tool is currently under construction — features may evolve.)
Inputs: RVT/IFC, schedules (P6/MSP), logistics plans Outputs: 4D animation, look-ahead views, variance report Integrations: Navisworks Timeliner, ACC Schedule/Issues Time to Value: 2–5 weeks

Example: Phased 4D sequence with crane paths and access zones highlighted.

Model–Schedule Linking

Auto-map model elements to WBS/activities; detect unmapped items and duplicate links.

Look-Ahead Planning

Generate 2–6 week look-ahead views and check access, laydown, permits, and long-lead items.

Logistics & Safety

Visualize crane paths, egress, barricades, and site traffic; flag conflicts with sequences and trades.

Sequence Optioneering

Compare alternate phasing strategies; estimate duration and risk impacts before committing.

1) Intake

Load RVT/IFC model(s), baseline schedule (P6/MSP), and site logistics drawings; define zones and phase breakpoints.

2) WBS & Mapping

Normalize codes and map model elements to WBS activities; flag missing data and create mapping rules.

3) Sequence Build

Generate time-phased install sequences by zone/trade; compute dependencies and resource overlaps.

4) Checks & Constraints

Detect access/egress conflicts, laydown shortages, crane interferences, and permitting or long-lead constraints.

5) Visualize & Review

Create 4D animations and saved viewpoints; run look-ahead reviews with stakeholders and capture comments.

6) Output & Sync

Export animations and snapshots; sync activity issues and changes to ACC/Timeliner; archive variance report.

Works With

Revit (models/schedules), IFC, Navisworks Timeliner, Primavera P6 / MS Project, ACC Schedule/Issues.

Deliverables

4D animation, look-ahead views, mapping table (elements↔activities), variance & constraint report.

Mapping Rules

Discipline- and client-specific rules for element-to-activity mapping and zone breakdowns.

Constraints Library

Firm rule packs for access, safety, crane, permits, and long-leads with risk scoring and thresholds.

Reporting

Custom animation presets, snapshot templates, look-ahead periods, and export formats.
