Abstract Globalization has transformed engineering design into a world-wide endeavor pursued by geographically distributed specialist teams. Widespread adoption of VR for design and the need to act and place marks directly on the objects of discussion in design reviewing tasks led to research on annotations in virtual collaborative environments. However, conventional approaches have yet to progress beyond the yellow postit + text metaphor. Indeed, multimedia such as audio, sketches, video and animations afford greater expressiveness which could be put to good use in collaborative environments. Furthermore, individual annotations fail to capture both the rationale and flow of discussion which are key to understanding project design decisions. One exemplar instance is offshore engineering projects that normally engage geographically distributed highly-specialized engineering teams and require both improved productivity, due to project costs and the need to reducing risks when reviewing designs of deep-water oil & gas platforms. In this paper, we present an approach to rich, structured multimedia annotations to support the discussion and decision making in design reviewing tasks. Furthermore, our approach supports issue-based argumentation to reveal provenance of design decisions to better support the workflow in engineering projects. While this is an initial exploration of the solution space, examples show greater support of collaborative design review over traditional approaches.
