This paper introduces a new framework for understanding, modelling and software engineering in construction information activities. The current framework is based on understanding that products are the results of processes, which are performed by actors. Such frameworks are influenced by the available technology. The Internet of today is supporting also other kinds of human activities: communication and social interactions among humans. The construction industry uses them as well but without having a proper understanding of their role. There is a gap in the current framework. In this paper, the relevant theories to specify this gap in terms of what could exist in theory and what is offered by technology are analysed. As a result, a new framework of construction information activities that fills the gap is proposed. The key concepts and relations among them are identified and elaborated within the existing framework. The framework introduces the third major integrative element of the otherwise fragmented construction information activities the social network the existing two being the physical building and its digital twin. The framework provides a theoretical and conceptual basis for designing, planning, creating, monitoring and evaluating construction-related online services that include a strong social component and use social media services.
