Update a 4D simulation with a scene layer and hosted 3D object - Part 2

|
By David Alvarez, David Álvarez
| Esri
4D simulation - Construction delay As outlined in Part 1 of this blog series, 4D simulation integrates time‑based data into a building information model (BIM), transforming a static 3D model into a dynamic representation of the construction process. By linking the model to the project schedule, teams can visualize how activities progress over time and gain deeper insight into sequencing, dependencies, and potential risks.

3D Object Layers - 4D simulation 4D simulation integrates time‑based information into building information model (BIM) to create a dynamic, evolving view of the construction process. By connecting the 3D model with the project schedule, it allows teams to visualize how construction activities unfold over time. This time‑sequenced representation helps stakeholders better understand the project timeline, anticipate potential challenges, and enhance overall planning and operations.

Get coordinates right: Quality control essentials for BIM and GIS integration

|
By David Alvarez, David Álvarez
| Esri
Facility managers in both municipal and private sectors are increasingly requiring digital deliverables—particularly 3D building information models (BIM) as part of their workflows, where location is  the common language between BIM and GIS. Location is not only a visualization detail,  it’s a foundational infrastructure component. Without reliable location data, integration between the two systems breaks down.
