The ACCORD project explores the opportunities and implications of digital visualization technologies for community engagement and research through the co-creation of three-dimensional models of heritage sites and objects. Techniques such as laser scanning, 3D modelling and 3D printing have largely remained in the domain of specialists. Consequently expert forms of knowledge and/or professional priorities often frame their use. Expressions of community-based social value are rarely addressed through their application. ACCORD seeks to address this through the co-design and co-production of a permanently archived and open-access research asset, which integrates co-produced digital models, user-generated contextual data, and statements of social value. In this paper we will focus on the results of the ACCORD project. We will discuss how community-based 3D visualization facilitates the production and negotiation of value and attachment, both in respect to the digital models that are produced and the monuments they represent. 3D recording and modelling are often promoted as a means of enhancing historic and scientific values through recording, analysis, interpretation and preservation. Here we argue that, used in collaboration with contemporary communities, they can be a rich environment for exploring and generating social and communal values. Drawing on our work with specific communities across Scotland we will show how collaborative production of 3D models generates a rich and complex set of relationships between material and digital heritage through which place, identity, belonging, and memory can be negotiated. Funded by the AHRC, ACCORD is a twelve-month partnership between the Digital Design Studio at the Glasgow School of Art, Archaeology Scotland, the University of Manchester and the RCAHMS.
