Hi @algonquin ,
Great question! Another candidate had a question along a similar vein awhile back. This might be helpful for you:
Renderings can absolutely be billed as a supplemental service (if agreed upon prior to signing B101 and included in table 4.1.1 ) or as an additional service (if requested after the B101 is signed).
I believe that the AIA included renderings, physical models, etc. in ‘Reimbursable’ as a way to indicated that the physical materials to make these can be reimbursed. For ‘renderings’ this would have been more applicable back in the days when they were hand done on expensive paper with expensive markers. At the same time, it’s also possible for example that you are hiring a professional photographer and billing the expense as a reimbursable to the owner rather than listing it as an hourly service your consultant is providing. It can absolutely depend on the situation!
Sorry I don’t have a nice black and white answer for you, but I hope this helps!
