The Master Plans (MP) used for Architectural Cultural Heritage conservation require specific standards for the documentation process. They must facilitate the achievement of the intended objectives about the knowledge acquisition and conservation of the building assets throughout the entire building lifecycle. Over time, the documentation of an MP, once the heritage building is under use, tends to become dispersed and the documentation generated during the building use is rarely introduced in the MP. Therefore, this contribution has the following objectives: 1) study of the requirements of MP deliverables; 2) study of the maturation requirements of the documentation processes and deliverables that are generated when applying the Building Information Modelling (BIM) methodology to an MP; 3) investigate if the application of the BIM strategies are suitable to respond to the needs of an MP in such a way that knowledge and conservation of heritage buildings are achieved; 4) verify that the exchange of information and the collaborative work among the different disciplines that generate documentation and deliverables guarantee a single, comprehensive, open, three-dimensional, and clear repository.
