Most BIM technologies today disconnect the production of permit drawings from the processes for fabrication and installation. When owners include subcontractors in preconstruction services (as they often do with general contractors) they have the ability to coordinate these activities and reduce errors.
What is needed then is a data backbone to connect the building design to the fabrication detailing and installation sequences. It is common practice to have architects design a façade, independently from the manufacturer who fabricates the façade, and also independently from the general contractor and subcontractors who install the façade system.
