Contracting-out asset maintenance: How arrangements adapt over time

Contracting-out and privatisation are key drivers of organisational and market change, which, along with technological and societal change, are ¿creating a new generation of infrastructures¿. While new institutional arrangements have the potential to improve maintenance efficiency through consistent and repeatable patterns of action - unanticipated difficulties in implementation can reduce the performance of these arrangements. Faced with unsatisfactory performance of contracting-out arrangements, government organisations may adapt and change these arrangements over time, with the aim of improving performance. This paper enhances our understanding of `next generation infrastructures´ by examining adaptation of the organisational arrangements for the maintenance of these assets, in a case study spanning 20 years.
