- Cost overruns are common in large and complex projects, especially in high speed rail ones. Budgeting for cost escalation is a major issue in the planning phase of these projects. This paper describes lessons learned on high speed rail in Italy and focuses on problems such as initial poor design, tactical budgeting, inadequate cost estimation and risk assessment, etc. The paper discusses possible means to avoid major flaws in the initial conceptual design of mega-projects. There is a growing understanding of the need to focus on the front-end phase in order to achieve more successful and cost-effective projects.

The Relationship

Purpose The purpose of this paper is to investigate how to improve the effectiveness of public participation in public infrastructure megaprojects (PIMs). Conflicts among stakeholders and uncertainty disrupt the success of PIMs when public participation is ineffective. Design/methodology/approach Secondhand data are collected to study the effectiveness of public participation in the Beijing–Shenyang High-Speed Rail (China) and the California High-Speed Rail (USA). The employed research method is an inductive case study. Findings Ineffective public participation can cause schedule and cost overruns and increase uncertainty in PIMs. The ambiguity of meaningful public participation, ineffective participatory approaches and overburden of public participation in environmental impact assessment are the causes of ineffective public participation in PIMs. Research limitations/implications Public participation has become an essential part in PIMs management. This study looks at the understanding of the relationship between public participation and the success of PIMs. Practical implications Legislative bodies should perfect the laws to guarantee meaningful public participation. Lead agencies should adopt additional effective participatory approaches to solicit public comments and identify critical voices. A dispute solution mechanism is necessary to solve public participation disputes in PIMs in practice. Originality/value Stakeholder and uncertainty management are important to the success of PIMs. This study reveals methods to improve the effectiveness of public participation to alleviate the conflicts among stakeholders and reduce uncertainty in PIMs.

Area Development

The Dutch Parliamentary Commission on Infrastructural Projects has conducted a parliamentary inquiry into the decisionmaking process and implementation control in two major infrastructural projects: the Betuwe Freight Line between Rotterdam and Germany, and the HSL - Zuid— the high-speed rail link which will connect Amsterdam with Belgium and France. The commission proposes a new assessment framework which gives parliament better control of the decisionmaking process for future large projects. In this contribution I discuss the development and design of large infrastructure projects, including the way the territorial impact of these projects is mitigated. I observe that problems are often approached from extremely narrow terms of reference, from one favourite solution, whereby countless potentially worthwhile alternative solutions are dismissed out of hand or enter the picture too late. In addition, problems concerning the mitigation of territorial impacts of infrastructure are misjudged in the beginning, and lead to cost overruns at a later stage. There is too much focus on the infrastructure track and not enough focus on area development. Also, the operation of the infrastructure project is misjudged and attention is too narrowly focused on the investment aspects of the project. I formulate some lessons for the future, not only for the Netherlands, but also for other modern countries. The timely generation and acknowledgement of infrastructure alternatives enhances the democratic process and quality of public decisionmaking.

The Impact

This paper measures the spatial evolution of urban agglomerations to understand be er the impact of high-speed rail (HSR) construction, based on panel data from fi ve major urban agglomerations in China for the period 2004–2015. It is found that there are signi ficant regional diff erences of HSR impacts. The construction of HSR has promoted population and economic diff usion in two advanced urban agglomerations, namely the Yang e River Delta and Pearl River Delta, while promoting population and economic concentration in two relatively less advanced urban agglomerations, e.g. the middle reaches of the Yang e River and Chengdu–Chongqing. In terms of city size, HSR promotes the economic proliferation of large cities and the economic concentration of small and medium-sized cities along its routes. HSR networking has provided a new impetus for restructuring urban spatial systems. Every region should optimize the industrial division with strategic functions of urban agglomeration according to local conditions and accelerate the construction of inter-city intra-regional transport network to maximize the eff ects of high-speed rail across a large regional territory.
