BIM Progress Monitoring and Tolerance Checking introduction
Tolerance Checking and Bim Progress Monitoring workflows give the same kind of analysis but their goals are different.
Bim Progress Monitoring indicates whether a part is installed or not (it focuses on tracking the progress of construction against the project schedule).
Tolerance checking indicates whether a part is installed in the correct position according to a given tolerance (it focuses on ensuring the accuracy and quality of construction).
Both cases can be confusing since matching a part and its measured points is mainly addressed thanks to their positions.
It is advisable to check manually the results during the second step of these workflows.
