This paper presents guidelines for the development of a design process for projects using precast façade panels, within a Building Information Modelling (BIM) environment. Precast concrete architectural panels (PCAP) were chosen as the starting point for structuring the proposal. The assembly logic justifies this approach: just as in the precast building system where the pieces are manufactured away from the construction site and are brought to it at the time of installation, in BIM, the elements and components of the Architectural, Engineering and Construction (AEC) industry are independently modelled and added to the model as and when required. Theoretical studies about the characteristics of PCAPs were conducted. That was followed by consultations with experienced professionals in the field to confirm the data selection and the necessary procedures for the design. Thereafter, flowcharts were made to guide the design process. A simulation of the new procedures was performed using the Revit 2013 software for validation. The proposal seeks to aid designers to define the necessary design steps, as well as the data used for modelling the elements. Helping designers to conceive designs using precast elements should stimulate and facilitate the use of precast components in Brazil.
