Can interoperability between disciplines be improved by adding phasing information using standardised coding?

With the increase of digitalisation in the construction industry, the need for structuring and classifying data is imperative. Due to the fragmentation and specialisation of the industry, digitalisation risks leading to a disconnect between the involved disciplines' different classification systems, impeding the interoperability of data transfer between disciplines. Thus, there is a need to explore how to capture the communication of data between different disciplines, leveraging the possibilities of multiple variables interconnect classifications of different disciplines. We applied a two-stage qualitative study focused on a specific part of a project, consisting first of interviews with practitioners and then a workshop with classification experts. We examined the use of standardised information in communication between disciplines. The main findings show that there are standards that support multiple properties that allow interconnections between disciplines; however, the currently used standards lack these possibilities. Thus, this paper contributes to the field through showing how the implementation of such a standard can solve challenges with interoperability and communication between disciplines.
