4D BIM Scheduling & Construction Simulation
Link models and schedules to review construction phases, logistics and sequences. Scope your 4D simulation, editable files and updates.
Our 4D scheduling service links model elements and work zones to construction activities so teams can review phases, logistics and alternative sequences. We define the planning question, prepare the relevant model and schedule links, and deliver the agreed simulations and review files. Editable projects, scenario comparisons and ongoing updates are specified in the proposal.
Schedule Import & Validation
We import the master schedule from Primavera P6 or MS Project, validate activity logic, and flag gaps or dependencies that may impact 4D mapping.
Model Preparation & Zoning
The 3D model is organized into work packages and zones that align with schedule activities, using Revit sets or Navisworks selection sets.
Activity-to-Object Mapping
Schedule activities are linked to model elements in Synchro Pro, establishing appearance profiles for planned, in-progress, and completed work.
Simulation & Conflict Review
We run the 4D simulation and review for sequence conflicts, logistical issues, and critical path visualization. Multiple construction scenarios can be modeled in parallel.
Animation & Stakeholder Handoff
Final animations are rendered for owner presentations, permit submittals, and subcontractor coordination packages, with editable Synchro files for ongoing schedule updates.
What to send for a 4D construction scheduling proposal
Tell us which decision the simulation should support: construction phases, access, logistics, or milestone presentations. This defines the level of detail for the 4D scope.
- Available schedule, source software, and date of its latest revision.
- Models or drawings, included trades, and work zones or package breakdown.
- Milestones, access constraints, and sequence scenarios to compare.
- Target delivery date and intended use: technical review, site meeting, or presentation.
How we define cost, timing, and deliverables
Pricing and timing depend on model preparation, activity and scenario counts, and review rounds. We agree whether delivery includes animations, editable files, and subsequent schedule updates. If a model or schedule is not available, tell us so that preparation can be scoped separately.

What is 4D BIM scheduling?
It links model elements or work zones to schedule activities to review construction over time. The scope defines which phases, sequences and constraints are represented.
What model detail is needed?
The required representation depends on the decision. Zone volumes may serve early phasing, while installation reviews can require specific components. There is no universal LOD minimum for every 4D use.
Do we receive editable files or only a video?
That is agreed in the scope. Specify animations, stills, editable schedule-linked files, review records and any subsequent updates you need.
How is the service priced?
Effort depends on model preparation, schedule complexity, scenario count, logistics representation and revision cycles. We define the deliverable package and update scope before quoting.
