In this Module, I would like to choose “Option 2 - 4D Simulation” and “Option 3 - Model-Based Estimating” as my assignment’s topics.

Option 2 - 4D Simulation

Public Link:

Firstly, I made some amendments to the structural model created in Module 6/7 by splitting the columns by levels to ensure all the columns could then be selected in Navisworks later accurately.

After the above changes, I exported the elements from the structural model to Navisworks as a Navisworks Cache file.

Then, I prepared a schedule re. the construction sequence of building structure by using Primavera P6 standalone version (See Figure 1). Generally, 28 days for columns and beams and14 days for slab and repeated the sequence for each level. Then, exported XER file to MPX file and added it as the data source of the 4D model.

After adding the task schedule, I attached the model elements to each tasks of the Timeliner tool (See Figure 2).

Finally, I ran the simulation of the 4D model with the task schedule to check the accuracy and realistic of the building construction (See Figure 3 and Video 1).

Option 3: Model-Based Estimating

For Option 3, I would like to carry out an estimation of the total cost on each level by looking at how much concrete do we need to complete the building construction based on the structural model.

I uploaded the same model above to the Assemble and filtered the concerned elements by levels (See Figure 4) . Then, I exported the table to Excel worksheet with the columns of quantity, unit and cost. (See Figure 5)
