    Optimizing Handover of As-Built Data Using BIM for Highways

    An efficient maintenance of the UK’s transportation network is of critical importance to the country’s economy and among the top priorities of the government and public agencies (e.g. Network Rail, Highways England). The public transportation agencies have huge data sets related to asset management and maintenance. However, those data sets are usually held in disparate platforms and have been historically developed using multiple standards and formats. As a result, full value of such data is often not fully realized. Effective management of asset data and availability of reliable information as and when needed, could bring in key benefits for effective management of the transportation network. This paper aims to present the initial findings of a research effort understanding the potential of Building Information Modelling (BIM) in handover processes for a more efficient maintenance of highways assets, and discuss the way forward. The research methodology applied is systematic literature review and two recent best practice cases in the Highways Sector. The research findings suggest that efficient data management through BIM could provide a structured framework to improve asset handover and maintenance. However, it is important to capture the current handover practices between the construction and maintenance phase, and maintenance processes in the UK’s highways sector, both of which seem to be absent in the literature at the moment

    The European trust crisis and the rise of populism

    We study the implications of the Great Recession for voting for antiestablishment parties, as well as for general trust and political attitudes, using regional data across Europe. We find a strong relationship between increases in unemployment and voting for nonmainstream parties, especially populist ones. Moreover, unemployment increases in tandem with declining trust toward national and European political institutions, though we find only weak or no effects of unemployment on interpersonal trust. The correlation between unemployment and attitudes toward immigrants is muted, especially for their cultural impact. To explore causality, we extract the component of increases in unemployment explained by the precrisis structure of the economy, in particular the share of construction in regional value added, which is strongly related both to the buildup preceding and the bursting of the crisis. Our results imply that crisis- driven economic insecurity is a substantial determinant of populism and political distrust

    Exchange networks, markets and trust

    Network-based transactions are attractive as a system for economic exchange because they give network members greater protection against opportunism and exchange hazards compared to more anonymous market transactions. At the same time, net- works restrict the possibilities to exploit economies of scale and other efficiency enhancing properties of markets. When the problem-solving capacity of networks do not make up for the losses generated by not trading with outsiders, trust is important to promote transactions among strangers in the anonymously market. This paper offers an economic analysis of this idea. With the help of a social evolutionary model, it is also demonstrated that mutual trust relations can survive in the anonymous market, even when there is a clear danger of opportunism, and the conventional mechanisms like repetitions and contracts are ruled out
