Collaborative design is an iterative process of selecting and evaluating solutions in the presence of several potentially conflicting requirements dictated by different professional expertise and preferences, a concept central to Building Information Modelling (BIM) implementation. In previous research, we showed that the core decision process can be better understood using argumentation-based models of practical reasoning. This allows the identification of the rationale and the relationships between conflicting issues, thus providing clarity and transparency for decisions achieved. This paper aims to take one step further in modelling this process, and suggests a novel methodological approach that translates collaborative, conceptual and perceptual activities related to design processes undertaken by design and construction professionals to correspondent argumentative dialogue types such as information seeking, deliberation and negotiation. Computational models of dialogue identify protocols for collaboration establishing reasons and evidence of claims made and joint identification of goals and solutions. Therefore, the proposed argumentative dialogue permits the formalisation of collaboration analysis, design decision steps can be monitored and the dependency relationships between professionals involved and decisions taken can be traced. Future research would develop a computational model to be employed by intelligent software agents to assist professionals in analysing complex collaborative decisions.
