❓ Frequently Asked Questions
What is 4D simulation in construction?
4D simulation links a building’s 3D model to the project schedule, allowing you to visualize when and where each activity occurs over time to optimize sequencing.
What is site sequencing, and why is it important?
Site sequencing arranges construction activities in the order they will be performed on site, considering space, access, and resources to minimize conflicts and delays.
Which tools are commonly used for 4D simulation?
Software that connects BIM models with schedules (e.g., Navisworks, Synchro, Vico) and project data from Primavera or MS Project are commonly used.
How does 4D simulation differ from a traditional 3D model?
A 3D model shows geometry; a 4D model adds the time dimension, showing the sequence and timing of activities on site.
