A general contractor typically requires access to as-built schedule information to control and manage construction projects.
In Taiwan, there currently exists a multitude of practice problems regarding updating an as-built schedule at the jobsite in Taiwan (Lin 2009).
The proposed approach is to enhance onsite updating of the as-built schedule integrated with BIM models for visual schedule management.
The 4D simulation approach is different from the BIM-based as-built schedule updating system, for which there have only been a few studies.
If the general contractor wants to utilize the commerce BIM software for the application of as-built schedule management, most 4D simulation functionality is incapable of meeting the requirement of updating the as-built schedule management in practice.
If the activity was not involved in the analysis scenario, the details of the activity would be inherited from the as-planned schedule, the as-built schedule, or the previous analysis scenario.
Because the EN, EC, and NE delays either impacted the as-planned schedule or occurred in the as-built schedule, computer-based schedule delay analysis methods should deal with these delays based on the adopted process-based and mathematical-model schedule delay analysis methods.
The anticipated completion time in the as-planned schedule was 23 days and the anticipated completion time in the as-built schedule was 35 days.
Depending on the requirement of the adopted process-based and mathematical-model schedule delay analysis methods, the data preparation involves collecting and organizing various schedule documents, for example, as-planned and as-built schedules.
1996) and isolated collapsed but-for (termed as ICBF) (Yang, Yin 2009) methods, the as-planned and as-built schedules were the basic documents, while the revised schedules that represented the identified delay events were additional documents.
