    This paper describes a novel risk indicator for extreme weather risks for use in transportation systems. The risk indicator is applied to the European transportation system indicating and ranking the risks for the 27 member states of the European Union (EU-27). The paper starts with definitions of hazards, vulnerability, and risk, based on relevant literature, and then operationalizes the risk, hazard, and vulnerability with the help of EU-27 data. Finally, the paper discusses the extreme weather risk indicator (EWRI) and evaluates its applicability and limitations. The risk indicator is a relative indicator: it should be viewed and treated as a ranking system. The devised indicator is able to assist decision makers at national and state as well as international and federal levels in the prioritization of extreme weather risks within their jurisdiction. The overall approach of EWRI is based on mainstream risk and vulnerability assessment research, following for the most part the existing conceptual models. The novelty of EWRI lies in its application area (transportation) and wide use of both empirical and statistical data. EWRI was used to assess the hazards, vulnerabilities, and risks of extreme weather for the EU-27, but nothing hinders its application, either in this form or a modified form, in other contexts

    Capabilities for managing project alliances

    Abstract The infrastructure and construction industry has for decades suffered from problems such as cost overruns, delays, disputes and low productivity. To transform old adversarial practices and industrial culture into more collaborative and innovative ways of working, new operational models for project delivery have been introduced. A project alliance is among the models developed to improve infrastructure and construction project performance by addressing problems of fragmentation and lack of integration. However, the growing body of conceptual and empirical research on project alliances within the field of project management does not include any in-depth investigation of the capability requirements and relevant processes for managing alliance projects. The goal of this dissertation is to contribute to the project alliance literature within the field of project management by exploring the capabilities needed by an inter-organizational alliance project organization and participating organizations to manage project alliances in the infrastructure and construction context. The research adopts a qualitative approach, utilizing the case study method and in-depth interviews as research methods. The empirical results, which relate to the first project alliances in the Finnish infrastructure and construction industry, highlight the importance of the alliance project organization’s collective capabilities for managing project alliances. Among these capabilities, inter-organizational integration management, collaborative project identity formation and opportunity management are of particular importance. In addition, each participating organization requires specific project alliance capability, which comprises both the ability to implement key activities over the project life cycle and the skills required by project-based organizations and participating individuals. Together, these organizational and project network-level capabilities form the basis for managing such projects.Tiivistelmä Infrastruktuuri- ja rakennusteollisuus on kärsinyt kustannusten ylityksistä, myöhästymisistä, erimielisyyksistä ja heikosta tuottavuudesta jo kymmenien vuosien ajan. Jotta vanhat, vastakkainasetteluun perustuvat käytännöt ja toimintakulttuuri voitaisiin muuttaa, uusia projektien toteutusmalleja on otettu käyttöön. Projektiallianssi on yksi yhteistoiminnallisista malleista, joka on kehitetty vähentämään toimialan sirpaloitumista ja edistämään integroitumista tavoitteena infrastruktuuri- ja rakennusalan projektien suorituskyvyn parantaminen. Lisääntyvästä konseptuaalisesta ja empiirisestä tutkimuksesta huolimatta, projektiallianssiin kohdistuva tutkimus ei ole tarkastellut organisaatioiden kyvykkyysvaatimuksia ja keskeisimpiä allianssin johtamiseen liittyviä prosesseja riittävän syvällisesti. Väitöskirjan tavoite on edistää projektiallianssin tutkimusta tuottamalla uutta tieto allianssihankkeisiin osallistuvien organisaatioiden kyvykkyysvaatimuksista sekä yhteisistä kyvykkyyksistä, joita projektiorganisaatio tarvitsee allianssiprojektin hallintaan infrastruktuuri- ja rakennusalalla. Tutkimus on toteutettu laadullisena tapaus- ja haastattelututkimuksena. Suomen ensimmäisistä infrastruktuuri- ja rakennusalan allianssihankkeista saadut empiiriset tulokset korostavat allianssiprojektiorganisaation yhteisten kyvykkyyksien merkitystä. Kyvykkyysvaatimukset kohdistuvat erityisesti organisaatioiden välisen integraation johtamiseen, yhteistyötä korostavan projekti-identiteetin muodostamiseen ja mahdollisuuksien hallintaan allianssiprojektissa. Näiden yhteisten kyvykkyyksien lisäksi jokainen organisaatio tarvitsee projektiallianssikyvykkyyden, joka koostuu allianssihankkeiden käynnistämiseen ja hallintaan tarvittavista taidoista ja kyvystä toteuttaa eri elinkaaren vaiheen kannalta keskeisiä toimintoja. Hankkeeseen osallistuvan organisaation projektiallianssikyvykkyys ja yhteiset projektiverkoston kyvykkyydet luovat perustan allianssihankkeen hallinnalle

    The extreme weather risk indicators (EWRI) for the European transport system

    The European 7th Framework Programme project Extreme Weather impacts on European Networks of Transport devised a holistic analysis of extreme weather risks for the transport system. The analysis provided an overview of extreme weather risks, or a risk panorama. The risk panorama was built on a probabilistic approach to extreme weather phenomena occurrences and on vulnerability analysis based on selected macro-level economic and transport system indicators of the member states of EU-27. The panorama covers all transport modes and views infrastructure-related risks, time delay risks, and accidents risks. In addition to climatic circumstances, the devised risk indicator is also dependent on regional circumstances, such as population and transport density and income level. This paper describes the construct and application of an extreme weather risk indicator (EWRI). EWRIs are counted for each country and each transport mode separately. Furthermore, this paper also presents the most significant extreme weather events in different parts of Europe and on the transport modes they affect the most
