What level of detail should be included in a 4D simulation?
A 4D simulation should include the level of detail that supports planning and scheduling decisions, although excluding very fine components like furniture and other decorative details. Including everything can overload the simulation, slow it down, and distract from the actual sequencing.
How can the feedback shown in a 4D simulation help you to optimize the project schedule?
A 4D simulation provides visual, time-based feedback that helps you catch sequencing errors, identify trade conflicts where two crews are assigned the same space simultaneously, spot logistical issues, and identify opportunities for overlap or ways to compress the schedule safely. The main benefits of linking model elements to schedule tasks allow for better communications, improve coordination, more accurate planning, and progress tracking.
How can model-based quantity takeoff improve the design process?
Model-based quantity takeoff improves design is more accurate quantities, instant updates when the model changes, early identification of major cost drivers, and improved coordination. When designer use early cost estimates to improve design by staying aligned with the budget, optimize building system, compare alternative design concepts, and reduce risk of redesign later.
