Barriers for pipe renewal – a comprehensive study.

This paper aims to identify the potential barriers to municipal pipe renewal in Norway and the opportunities to mitigate these barriers. The research explores why the renewal rate on the pipe network is lower than the recommended through a research study of Norwegian municipalities, by gathering exploratory data as a base for a series of semi-structured interviews. The interviews were compiled into a data set and analysed to identify barriers to pipe renewal. The study found that the main barriers to pipe renewal were in the organizational and project implementation segments of the renewal projects. The most prominent groups of barriers were coordination and cooperation, followed by barriers to internal resources such as accessible human resources, time, and economics. Technical aspects during installation were less significant. The findings can impact project implementation by providing knowledge on the barriers and where to focus resources for optimising pipe renewal projects. [ABSTRACT FROM AUTHOR]
