Even though infrastructure assets serve society for long time, asset information does not last that long in all cases. This is primarily due to technological and organisational changes and disruptive events over long time. Therefore, information future-proofing considerations are required to be incorporated in order to sustain the assets. However, even though companies consider some aspects but largely mechanisms for information fiiture-proofing assessments are not fully known. As part of the information future-proofing research conducted at CSIC ; what, why and how characteristics of information future-proofing were explored through a number of semi-structured interviews and workshops with leading companies dealing with infrastructure assets. This paper presents an information future-proofing assessment approach as an output of the CSIC future-proofing research. The information future-proofing assessment approach was applied in case studies of Hertfordshire County Council bridges and structures. University of Cambridge department building, Crossrail tunnels and pumps, and London Underground infrastructure.
