As a result, construction drawings were issued accurately in a synchronized manner.
Along with this, the use of BIM for shop drawings brought down the amount of material wastage to 1.22% (estimation on drawings). This was lower than the project target of below 2% and resulted in a total saving of 44,301 kg of rebar for superstructure.
In addition, communication and exchange of information among stakeholders became more efficient at every stage.
A clear sign of this was that the amount of RFI decreased significantly at the construction stage. The content of most RFI became focused on a change in material due to scarcity of material or to conform with local market conditions.
Furthermore, the use of BIM 360 to manage RFI expedited the resolution process, such that all issues with involved parties could be promptly solved within one hour.
