<p>RV 3/25 is a large infrastructure project consisting of a new 25 km highway in Hedmark County in Norway. The project is organized as a PPP-project and includes 20 concrete bridges and 8 timber glulam arch bridges.</p><p>In the project the use of BIM-models and parameterization has been significant and has evolved greatly throughout the project. The work ranged from macro BIM with large coordination models with all disciplines included, to micro BIM-models for bridges including all details needed for construction. For 5 concrete bridges, the BIM-model was the only product delivered to the contractor without producing design or construction drawings.</p><p>For the 8 glulam arch bridges in timber, parameterization was employed for establishing both the BIM-models and the analysis models. This was vital to achieving the goal of following the strict design schedule with a small design team. It also proved very valuable in the shaping phase of the bridges. Between 80% and 90% of the objects in the finalized BIM-models were included in the parameterization. The product delivered to the contractor was design drawings, most of which were generated directly from the BIM-model, thus benefiting from its advantages.</p><p>The use of BIM has proved to be cost and time-efficient during design. This paper presents the challenges and benefits of using parameterization and BIM in a large infrastructure project with focus on bridge design.</p>

<p>Open-spandrel, concrete arch bridges were a common bridge design in the United States during the early 1900s. Many of these bridges are now urban landmarks and listed historic structures that local jurisdictions wish to rehabilitate, including widening the deck to more safely accommodate pedestrians and bicyclists. However, decades of exposure in harsh climates have led to advanced deterioration and reduced load ratings for most extant examples. Further complicating rehabilitation, the height, and arch-reliant behavior of these bridges make construction access, staging, and maintenance of traffic difficult. Drawing upon the authors’ experience with several bridges of this type, this paper discusses best practices and special considerations for investigating and rehabilitating historic concrete arch bridges to extend their life.</p>

Purpose The historic Belt and Road Initiative (BRI) is an economic reform policy proposed by the Chinese Government that focuses on connectivity, improved collaboration and more robust economic relations. This paper aims to identify risks involved in BRI infrastructure project and establish a hierarchical relationship among them. Design/methodology/approach The methodology includes two phases, namely, identification of significant risks involved in the BRI project using systematic literature review and to develop a hierarchical relationship between the risks using interpretive structural modeling followed by the MICMAC analysis. Findings This work has identified the 11 risks of BRI infrastructure projects through academic literature. Based on the analysis, economic risk (R3), environmental risk (R1) and political risk (R2) are placed at level six in the ISM model and can significantly influence BRI infrastructure projects. These risks have high driving power, which exaggerates other risks. Research limitations/implications This study would help Engineering Procurements and Construction contractors in strategic decision-making select risk mitigation strategies and make robust and efficient infrastructure projects. However, additional factors may be considered, which are essential for the BRI infrastructure project. Originality/value This research’s novelty lies in the advancement of expertise in project risk assessment. This study contributes by identifying the most significant risks involved in the BRI project. The integrated ISM-MICMAC approach provides a macro picture of BRI project risks to formulate better strategies for its success.

Purpose Public involvement is essential in the creation of effective local strategies for the development of a sustainable built environment, yet there has been little research on stakeholder motivation and engagement in the creation of infrastructure-project value, in the entire life cycle of a given project, while different markets show that overlooking stakeholders can negatively affect the success of an infrastructure project. The purpose of this paper is to fill the theory-practice gap that has been discerned, and thus study how early public involvement determines the success of an infrastructure project, which is identified with its value creation (effectiveness, sustainability and utility). Design/methodology/approach This research entails a combination of methods. A case study analysis allowed observation of the role the stakeholders play and of how the relationships, perspectives, expectations and risks, along with other soft issues, continue to affect projects. The case study required comprehensive examination of project documentation and conduction of interviews. To collect data, focused group interviews and semi-structured interviews were used, supported with direct questionnaire surveys. Findings The study provides evidence that early public engagement can contribute to infrastructure-project value (effectiveness, sustainability and utility). Practically speaking, the stakeholder analysis performed allowed proposal of a general stakeholder analysis framework for infrastructure projects. It can be implemented at each investment phase of the project life cycle, since stakeholders and their motivation may develop and/or change over time, which necessitates development of proper managerial strategies. The findings highlight the opportunities and the challenges faced by stakeholder management. Research limitations/implications The limitation of this study derives from the fact that the sample size was small, which was necessary for an in-depth qualitative research and application of the case study method. The observations were made on a selected case study, within a limited period of time, thus the context of the analysis as well as the stakeholder perception was subject to possible change. The research limitations concern the provisional nature of the information obtained, the cross-sectional nature of the analysis itself, and, finally, the inability to predict all future events. Ultimately, stakeholder mapping was performed for the operational phase of the investment exclusively, while the analysis was limited to identification and classification of the stakeholders, including their relationship with the project. Practical implications The research conclusions provide useful input for future research on development of effective strategies for management of the shareholders that are related to a given infrastructure project, in order to achieve project success. Simultaneously, from a property perspective, the research has contributed to a better understanding of the importance of infrastructure, on the part of real estate stakeholders. Social implications Application of the approach proposed in the study may contribute to early development and implementation of appropriate trust-building processes. The building of relationships between stakeholders enables checks and balances, promotes short- and long-term project benefits, and increases the value of a project. Originality/value The novelty of the research consists in the connection, as part of infrastructure projects, of the theory of consumption values and the concept of an investment cycle with the framework of stakeholder analysis.

In Western liberal democracies the planning of mega transport infrastructure projects is guided by public interest claims typically expressed through legislation and political mandates. But with the infrastructure boom being observed in many cities since the Global Financial Crisis, and the need to address unprecedented levels of urbanisation, the level of politicisation directed at infrastructure projects draws attention to how the public interest is treated in the planning and management of complex mega transport infrastructure projects in diverse local contexts. Looking to Sydney, an advanced neoliberal city building the largest transport infrastructure project in Australian history, we examine how public interest is asserted in a way that reinforces legitimacy of the process and consensus for the project. Under these conditions, planners fail or are unwilling to raise additional or new public interest issues. The vagaries of public interest mean that in being open to interpretation the public interest can be easily captured by the interests of capital and of ruling politicians. This raises important questions for urban studies about the role governments and, in particular, public-sector planners can play in advocating for actually existing public interest issues such as environmental sustainability without it amounting to just rhetoric with no follow through.

A method to identify the attractiveness for private financing of a transport infrastructure project is presented. The objective of the method is to assist the public sector in identifying the attractiveness of a transportation infrastructure project for private financing, highlighting the factors that tend to reduce such attractiveness and providing the means to examine the viability of alternative risk-allocation scenarios related to risks undertaken by the state or private sector. The method allows for the simulation of the private sector’s attitude toward risk, employing practices of risk assessment in investments. Its innovation lies in how the whole process is structured so that participants understand beforehand whether an agreement can be concluded and which factors involved are critical. A key property of the method is the ease by which priorities of different risk components are synthesized into a hierarchical form through pairwise comparisons. This method, although targeted primarily for the public sector, could assist both private and public stakeholders investing in transport infrastructure projects (termed private-public partnerships) to reach an agreement. Basically, it is an interactive process characterized by the conflicting objectives and judgments of both public and private sectors.

Taking arch bridges, including deck, half-through, and through arch bridges (short for DAB, HTAB, and TAB) as examples, mechanics analysis models of longitudinal interaction between continuously welded rails (short for CWRs) and arch bridges are established. Based on the finite element method (FEM), the longitudinal interaction calculation software of CWR on arch bridges has been developed. Focusing on an HTAB, the tension, compression, and deflection conditions are calculated and analyzed. The results show that the mechanics analysis models of three types of arch bridges can truly reflect the real state of the structure; the calculation software can be used for systematic research of the CWR on arch bridge; as for HTAB, temperature difference of arch rib has a small effect on rail tension/compression, and arch bridge can be simplified as a continuous beam for rail tension/compression additional force calculation; in calculation of deflection conditions of HTAB, it is suggested that train loads are arranged on half span and full span and take the direction of load entering bridge into account. Additionally, the deflection additional force variation of CFST basket handle arch bridge is different from that of ordinary bridge.

 The paper analyzes structural alternatives in the implementation of infrastructure projects on the example of main gas pipelines. Particular attention is paid to the impact of various forms of procurement procedures on the course and result of the implementation of the infrastructure project as a whole. It is shown that the choice of procurement method can influence the structure of incentives and risks of the parties involved, as well as indirectly impact on the establishment of the market price setting, the level of product quality in the industry, and the complex cost of project implementation. Noting the extreme importance of the issues of ensuring the quality of the products used, the authors review the available structural alternatives for organizing quality control, show the possible mechanisms of the influence of the downtime of enterprises on reducing the level of industry competencies.

As infrastructure projects get larger and more complex, innovation, which is highly dependent on collaboration and interactions among stakeholders, is critical to meet the challenges. Nevertheless, the existing literature is lacking in terms of studies into the spread of cooperative behaviors in infrastructure project innovations, on which project success is highly contingent. Hence, based on network science theories, this study aims to shed light on the cascade processes of cooperative behaviors in the evolution of collaborative innovations within infrastructure project networks and the impact of various network structures on the cascade effect. The results indicate that the number of initial innovation adopters is positively correlated with the role that the initial adopters play and the cascade effect of collaborative innovation on infrastructure projects. It is also shown that the cascade effect of collaborative innovations is contingent on project network structures. Furthermore, the results also suggest that network connection is positively correlated with cascade speed, scale, and time to reach a stable state. This study is the first to explore the cascade effect of stakeholders’ interactions vis-a-vis collaborative innovation in infrastructure projects. The findings could assist policy-makers and project managers in taking appropriate measures to encourage innovation in infrastructure projects.
