A review of current risk pricing practices in the financial, insurance and construction sectors is conducted through a comprehensive literature review. The purpose was to inform a study on risk and price in the tendering processes of contractors: specifically, how contractors take account of risk when they are calculating their bids for construction work. The reference to mainstream literature was in view of construction management research as a field of application rather than a fundamental academic discipline. Analytical models are used for risk pricing in the financial sector. Certain mathematical laws and principles of insurance are used to price risk in the insurance sector. construction contractors and practitioners are described to traditionally price allowances for project risk using mechanisms such as intuition and experience. Project risk analysis models have proliferated in recent years. However, they are rarely used because of problems practitioners face when confronted with them. A discussion of practices across the three sectors shows that the construction industry does not approach risk according to the sophisticated mechanisms of the two other sectors. This is not a poor situation in itself. However, knowledge transfer from finance and insurance can help construction practitioners. But also, formal risk models for contractors should be informed by the commercial exigencies and unique characteristics of the construction sector.

The complexity of construction projects and the fragmentation of the construction industry undertaking those projects has effectively resulted in linear, uncoordinated and highly variable project processes in the UK construction sector. Research undertaken at the University of Salford resulted in the development of an improved project process, the Process Protocol, which considers the whole lifecycle of a construction project whilst integrating its participants under a common framework. The Process Protocol identifies the various phases of a construction project with particular emphasis on what is described in the manufacturing industry as the ‘fuzzy front end’. The participants in the process are described in terms of the activities that need to be undertaken in order to achieve a successful project and process execution. In addition, the decision-making mechanisms, from a client perspective, are illustrated and the foundations for a learning organization/industry are facilitated within a consistent Process Protocol.

There is a growing concern in reducing greenhouse gas emissions all over the world. The U.K. has set 34% target reduction of emission before 2020 and 80% before 2050 compared to 1990 recently in Post Copenhagen Report on Climate Change. In practise, Life Cycle Cost (LCC) and Life Cycle Assessment (LCA) tools have been introduced to construction industry in order to achieve this such as. However, there is clear a disconnection between costs and environmental impacts over the life cycle of a built asset when using these two tools. Besides, the changes in Information and Communication Technologies (ICTs) lead to a change in the way information is represented, in particular, information is being fed more easily and distributed more quickly to different stakeholders by the use of tool such as the Building Information Modelling (BIM), with little consideration on incorporating LCC and LCA and their maximised usage within the BIM environment. The aim of this paper is to propose the development of a model-based LCC and LCA tool in order to provide sustainable building design decisions for clients, architects and quantity surveyors, by then an optimal investment decision can be made by studying the trade-off between costs and environmental impacts. An application framework is also proposed finally as the future work that shows how the proposed model can be incorporated into the BIM environment in practise.

The benefits and applications of virtual reality (VR) in the construction industry have been investigated for almost a decade. However, the practical implementation of VR in the construction industry has yet to reach maturity owing to technical constraints. The need for effective information management presents challenges: both transfer of building data to, and organisation of building information within, the virtual environment require consideration. This paper reviews the applications and benefits of VR in the built environment field and reports on a collaboration between Loughborough University and South Bank University to overcome constraints on the use of the overall VR model for whole lifecycle visualisation. The work at each research centre is concerned with an aspect of information management within VR applications for the built environment, and both data transfer and internal data organisation have been investigated. In this paper, similarities and differences between computer-aided design (CAD) and VR packages are first discussed. Three different approaches to the creation of VR models during the design stage are identified and described, with a view to providing sharing understanding across the interdiscipliary groups involved. The suitable organisation of building information within the virtual environment is then further investigated. This work focused on the visualisation of the degradation of a building, through its lifespan, with the view to provide a visual aid for developing an effective and economic project maintenance programme. Finally consideration is given to the potential of emerging standards to facilitate an integrated use of VR. The convergence towards similar data structures in VR and other construction packages may enable visualisation to be better utilised in the overall lifecycle model.

There is limited understanding of the role of services in the wave of globalisation and how the strengths of the UK service sector help to respond to the challenge of global competition. The way in which the construction export data are collected does not reflect the impact of globalisation and the changes in the construction business environment, such as increasing foreign ownership, foreign affiliates, and changing forms of procurement. The paper describes construction service exports, how they are collected and classified, highlighting the challenges of recording the export performance of construction services in a changing world. A case for change is made to ensure the collection of statistics better reflects the role of construction professional services

The construction industry has become a truly global network of interconnected stakeholders making demands which require the involvement of skilled workforces from all over the world. Construction Management Strategies sets the foundations for understanding and managing construction’s inherent complexity and uniqueness. It establishes clear definitions of commonly accepted terms like built environment, construction, civil engineering, etc. which are often given confusing and conflicting interpretations. It cuts through the plethora of overlapping role titles currently used in the construction sector that make it difficult to establish how projects are actually managed.

The idea of a community of practice (CoP) has been offered as the engine to unlock the potential of organizational resources, mainly knowledge and people, to achieve the strategic goal of sustained competitiveness. The relevance and application of CoPs in large UK contracting companies was investigated using two case studies. Contrasting variations in the understanding of the concept between the two contracting companies were observed. While a CoP was applied in one company with strategic intent, the concept was not fully understood in the other. In one company, only a third of CoP members surveyed agreed that CoPs were a vehicle for driving best practice and innovation throughout the business; this compared with more than 60% in agreement in the other contracting firm. The higher agreement and satisfaction of CoP members in the latter case study was the result of the management's understanding and commitment. CoPs require time and organizational support to mature. The strategic inception and management support of CoP application is vital for their maturation and progress. Although the construction industry change discourses portray CoPs as fostering an environment of trust, and hence serving as innovation and competiveness enablers, their potential contribution to contracting firms does not provide a compelling case and hence merits further research studies.

Market liberalization in emerging-market economies and the entry of multinational firms spur significant changes to the industry/institutional environment faced by domestic firms. Prior studies have described how such changes tend to be disruptive to the relatively backward domestic firms, and negatively affect their performance and survival prospects. In this paper, we study how domestic supplier firms may adapt and continue to perform, as market liberalization progresses, through catch-up strategies aimed at integrating with the industry's global value chain. Drawing on internalization theory and the literatures on upgrading and catch-up processes, learning and relational networks, we hypothesize that, for continued performance, domestic supplier firms need to adapt their strategies from catching up initially through technology licensing/collaborations and joint ventures with multinational enterprises (MNEs) to also developing strong customer relationships with downstream firms (especially MNEs). Further, we propose that successful catch-up through these two strategies lays the foundation for a strategy of knowledge creation during the integration of domestic industry with the global value chain. Our analysis of data from the auto components industry in India during the period 1992–2002, that is, the decade since liberalization began in 1991, offers support for our hypotheses.

Changes to client requirements are inevitable during construction. Industry discourse is concerned with minimizing and controlling changes. However, accounts of practices involved in making changes are rare. In response to calls for more research into working practices, an ethnographic study of a live hospital project was undertaken to explore how changes are made. A vignette of a meeting exploring the investigation of changes illustrates the issues. This represents an example from the ethnographic fieldwork, which produced many observations. There was a strong emphasis on using change management procedures contained within the contract to investigate changes, even when it was known that the change was not required. For the practitioners, this was a way of demonstrating best practice, transparent and accountable decision-making regarding changes. Hence, concerns for following procedures sometimes overshadowed considerations about whether or not a change was required to improve the functionality of the building. However, the procedures acted as boundary objects between the communities of practice involved on the project by coordinating the work of managing changes. Insights suggest how contract procedures facilitate and impede the making of changes, which can inform policy guidance and contract drafting.

Objective: To clarify how infection control requirements are represented, communicated, and understood in work interactions through the medical facility construction project life cycle. To assist project participants with effective infection control management by highlighting the nature of such requirements and presenting recommendations to aid practice. Background: A 4-year study regarding client requirement representation and use on National Health Service construction projects in the United Kingdom provided empirical evidence of infection control requirement communication and understanding through design and construction work interactions. Methods: An analysis of construction project resources (e.g., infection control regulations and room data sheets) was combined with semi-structured interviews with hospital client employees and design and construction professionals to provide valuable insights into the management of infection control issues. Results: Infection control requirements are representationally indistinct but also omnipresent through all phases of the construction project life cycle: Failure to recognize their nature, relevance, and significance can result in delays, stoppages, and redesign work. Construction project resources (e.g., regulatory guidance and room data sheets) can mask or obscure the meaning of infection control issues. Conclusions: A preemptive identification of issues combined with knowledge sharing activities among project stakeholders can enable infection control requirements to be properly understood and addressed. Such initiatives should also reference existing infection control regulatory guidance and advice.

Aligning information systems (IS) solutions with business goals and needs are crucial for IS activities. IS professionals who are able to work closely with both the business and technical staff are key enablers of business and IT alignment. IS programs in higher education (HE) institutions have a long tradition of enabling graduates to develop the appropriate skills needed for their future careers. Yet, organizations are still having difficulty finding graduates who possess both the knowledge and skills that are best suited to their specific requirements. Prior studies suggest that IS curricula are often ill-matched with industry/business needs. This study reports on the business analysis curricula (re) design which was undertaken to align it with a key professional body for the IS industry. This study presents the approaches taken in the (re) design of the module, and provides a discussion of the wider implications for IS curricula design. The results show a positive outcome for the HE and professional body partnership.

A orientação teórica que divide a nossa sociedade em um modelo Industrial e em um modelo Pós-Industrial vem ganhando cada vez mais espaço e importância no estudo das organizações. Vários estudos acadêmicos nacionais e estrangeiros relatam o fato de que as organizações atuais mudam rapidamente o seu discurso a fim de adaptar-se às modificações que ocorrem nos processos produtivos e na gestão de pessoas, porém a implementação prática destas mudanças não ocorre de modo tão rápido quanto quer a mudança no discurso. Dado este período de transição, a distância entre a teoria professada e a prática efetiva nas organizações aumenta, surgindo maiores contradições entre discurso e prática, o que tem conseqüências para a produtividade. Estudamos neste projeto dois modelos de Gestão de Pessoas: O modelo Instrumental e o Modelo Político. Muitas organizações dizem que adotam o modelo Político, mas na prática mantém estruturas próximas ao modelo Instrumental. Neste relatório realizamos dois estudos de caso: Um em uma grande empresa nacional, a Souza Cruz, onde a empresa conseguiu superar a dicotomia discurso-ação implantando gradualmente o modelo Político de Recursos Humanos em consonância com a implementação de um sistema de informação que modificou toda a área de gestão de pessoas. Em segundo lugar, apresentamos um outro estudo de caso realizado em uma grande cooperativa Agro-Industrial onde já havia se consolidado práticas relativas ao modelo Político de Gestão de Pessoas e a implementação do modelo Instrumental, em uma ação top-down pelo presidente provocou fenômenos de resistência à mudança e a não implementação efetiva do ERP Entreprise Resource Planning na organização. Comparamos assim um estudo de caso que confirma a problemática levantada pela revisão da literatura (o da cooperativa) e um outro estudo de caso que oferece pistas de como evitar-se este problema, construir um sistema organizacional coerente e seguir em frente monitorando um sistema de aprendizagem baseado no modelo Político de Recursos Humanos.

A técnica de componentes de variância pode oferecer perspectivas interessantes na avaliação dos vários tipos de efeitos que afetam desempenho em uma abordagem descritiva. Após o trabalho original de Rumelt (1991) vários autores estudaram a composição de variância do desempenho das firmas, decompondo este elemento em fatores de firma, de corporação, de indústria e efeitos de ano. A maioria vasta destes estudos indica efeitos da firma como o componente dominante de variância explicada. Isto alimentou o debate entre a organização industrial e a RBV, ainda que a importância de efeitos corporativos apresentou resultados contraditórios e pareceu ser sensível à amostra e período analisados. Foram identificados efeitos de ano muito pequenos ou inexistentes. Todos os estudos previamente elaborados foram baseados em dados dos EUA e descrevem o ambiente empresarial de economia americana. Este estudo visa verificar se a estrutura de variância de rentabilidade em outros países é diferente da americana.
