In the "Checklist Phase" you send the Architectural, Structural, Mechanical and Electrical Building Information Models to AGI. We prefer Revit files, but can also work with IFC files. In this phase, we perform a check based on the present information in your BIM and process the missing information in a clear "Checklist". The check is based on the "playing rules" described in our "Infographic Subsequently, you send this Checklist to the General Contractor and MEP (sub)contractor(s) and further discuss the BIM design workflow by providing a project specific presentation. It is important to process the missing information in BIM – as indicated by our Checklist – to ensure an optimal functionality of the Orange Button® BIM firestop design software. The responsibility of processing the correct and complete information in BIM lies with the designing parties.
