4D simulations are often used to show the construction sequence for an entire project, but shorter simulations that focus on a specific period of time are also useful.
Shorter simulations allow for a greater amount of detail, while longer simulations show the overall progression of the construction project. A construction sequence simulation that targets the step-by-step progression of a complicated section will help contractors visualize the tasks needed to build it. For example, plumbing and electrical systems require a great amount of detail to show the exact order of installation.
How can the feedback shown in a 4D simulation help you to optimize the project schedule?
The main benefits of linking model elements to the project schedule are convenience and clarity. If an element in the simulation seems to appear too quickly, such as a large system of beams being built in a few days, the designer should allot more time for its construction in the project schedule. With 4D simulation, viewers can easily see which elements are expected to be finished at which date. Therefore, contractors can plan and execute the construction process more accurately.
How can model-based quantity takeoff improve the design process?
Model-based quantity takeoff can improve the design process by establishing a more realistic perspective on the relationship between a design and its real-life construction costs. Designers can improve their designs by optimizing the most effective execution of their vision with the lowest cost. This can also provide insight on redundant or unrealistic aspects of design before they are implemented, so that construction funds are allocated with reason.
