4D construction simulation

4D construction simulation: your schedule, BIM model and site in one live model

4D scheduling links time to the 3D model. Plan104 goes further: the platform combines your CPM schedule, BIM model and site scans into a live, one to one simulation of the project, with every crew and every name on the model, hour by hour.

What you can do with the simulation

Press play on the schedule

Watch the day hour by hour with every crew where the schedule says it should be.

Crew congestion alerts

When two activities need the same space at the same time, the platform flags both before anyone is on site.

Installation sequence testing

Pick the order the elements go in, simulate it and compare it with the current plan.

What-if scenarios

Change crew size, duration or productivity without touching the live schedule, then send the scheduler every resulting change.

Manpower by activity

See how many people each day needs, by company and by activity.

A digital twin of the site

Site scans and as-built data keep the model aligned with the real site. Progress tracking

Built on a real CPM schedule

A simulation is only as good as the schedule behind it. Our Primavera P6 scheduling team builds and maintains schedules with the logic, coding and durations a 4D model needs, which is why we offer scheduling and the platform together. See scheduling plus platform.

Frequently asked questions

What is 4D construction simulation?

4D simulation links the construction schedule to a 3D model so the team can see how the project is built over time. Plan104 adds site scans and crews to make it a live model of the real site.

Is this the same as a digital twin?

It works as a construction digital twin: the model reflects the schedule, the BIM model and the latest site conditions from scans.

Do we need a BIM model?

A BIM model gives the best result, and site scans help keep the simulation aligned with the real site.

Which schedules can the simulation use?

CPM schedules from Oracle Primavera P6, built and maintained by your team or by Plan104 schedulers.
