4D BIM simulation virtual construction and project planning
We add time to the 3D model to show how construction progresses at every stage of the schedule, improve coordination and anticipate risks.

The project is built first in the model
4D BIM simulation adds time to the 3D model. We connect BIM geometry with the project schedule in MS Project or Primavera P6 to create an accurate virtual construction: analyzing construction sequences, critical paths and space–time clashes, and optimizing site logistics. We simulate in Autodesk Navisworks Manage.

Two-storey building. Sequence from the TimeLiner simulation with a rescheduled programme: construction start 1 Sep 2026, planned completion 3 Feb 2027. No work on Sundays, public holidays or 24, 25 and 31 December, 1 and 7 January. The final image is an AI-generated visualization from the model, not a site photograph.

Frequently asked questions
Which software is used for 4D simulation?
Navisworks Manage, which combines spatial coordination with construction planning to simulate, analyze and manage changes as construction progresses. The schedule can come from MS Project or Primavera P6.
Do I need a 3D model?
Not necessarily. If the project has no model, we develop it from the drawings as the first step; if one exists, we review it and split it into levels, zones and phases according to the schedule.
What level of detail (LOD) does the simulation need?
We work with LOD 300 to 350 models: every element with its final geometry and position, organized according to the schedule activities.
Can planned and actual progress be compared?
Yes. With the actual progress provided by the site team, the simulation contrasts planned against actual progress to support control and tracking.
Does the simulation include site logistics?
Yes. Laydown areas, machinery and access can be simulated to review their sequence and detect overlapping activities on site.
What should I send for a quote?
The project model or drawings, the construction schedule, the expected scope of the simulation and the target timeline.
What does 4D BIM planning cost?
It depends on the complexity and size of the project. We define it in the quote based on the information received.
How long does the simulation take?
The timeline is set by the scale of the project or the date the client needs: we assess the scope and confirm in the quote whether it can be met. We reply to every inquiry in under 24 business hours, and the formal quote takes 1 to 2 business weeks from the moment we receive the complete information.
Do you work with clients outside Colombia?
Yes. We are a fully remote firm with projects in Colombia and abroad; we deliver the Navisworks files, the simulation videos and the model in Revit 2026 or later, or IFC.
Do you sign confidentiality agreements?
Yes. When the project requires it, we sign a non-disclosure agreement (NDA) before receiving any information.
