    Initiation of capital projects in industries having an operational focus: an Australian stevedoring case example
    Aldaghlas, H ; Hui, FKP ; Duffield, CF (Emerald, 2020-12-15)
    Purpose: The initiation phase of capital projects is critical as this is where the highest number of options exist for modifying the project with minimal expenditure. Government and large organisations frequently involved in major capital projects have extensive procedures for this phase, yet organisations having an operational focus (like major container terminal stevedores), that only occasionally undertake capital projects face the dilemma of the trade-off between project planning and the management of operations. This research reported in this paper investigated the impact of industry operational considerations on the initiation of capital projects. Design: In addition to an extensive literature review, a living research investigation of real projects initiated by a stevedoring company operating in Australia has been observed; the primary author of this paper spent six months as a participant/observer and witnessed the initiation of 12 capital projects. The collected data was qualitatively analysed using a four-step coding method. Findings: The findings confirm that project initiation is a challenge for organisations who only spasmodically undertake capital projects and available project management frameworks do not necessarily consider the impact of such an organisation's culture. Issues identified that may have a negative impact on the initiation phase include lack of workplace trust, high individualism, ineffective interdepartmental communication, lack of resources and engineering and safety complexity. Originality: The study investigated an underexplored industry within the context of project initiation, using the Australian stevedoring as a case study. This initial investigation suggests that a tailored project management framework is needed for the initiation phase of projects to reflect the unique nature of the stevedoring industry and by inference other industries that have a strong operational focus.

    Reliability-Based Decision Support Framework for Major Changes to Social Infrastructure PPP Contracts
    Geng, L ; Herath, N ; Zhang, L ; Kin Peng Hui, F ; Duffield, C (MDPI AG, 2020)
    In the operational phase of public-private partnership (PPP) contracts, undue delay in addressing real needs may lead to poor service outcomes; conversely, commencing variations to a PPP agreement on the whim of end-user runs the risk of reducing the value created by detailed structuring and considerations undertaken in establishing agreement. This difficulty is exasperated as there is generally a lack of understanding by the end-user as to the specifics of service delivery performance requirements contracted. In order to address this question, this study, for the first time, develops a reliability-based decision support framework (RDSF) that incorporates end-user’s perceived service quality (i.e., how satisfied it is with the space, operation and maintenance activities) with those specified in the PPP agreement, and further identifies when the gap between end-user’s expectations and contractual obligations warrants reconsideration. This developed framework is then implemented to test the data gathered from three PPP schools in Australia based on both a current snapshot of performance data, i.e., abatements as gathered through contract documents and end-user’s perception through in-depth interviews, and a projected scenario of the future as well. Reliability analysis used here compares time-dependent risk profiles of current and expected performance and thereby identifies major changes in a PPP contract that would sensibly require reconsideration. The specific results indicate there is no current difficulty between end-user’s perception and the contract. However, the projected long-term scenario demonstrates how the decision framework can identify areas for review and changes if end-users are more dissatisfied with the service being achieved. The RDSF is capable of quantifying current service performance, considering the engagement of the end-user. Thus it enriches theories in the field of performance management system (PMS), and also contributes to knowledge regarding an evidence-based test for justifying possible agreement modifications or additional works in social PPPs operations. In addition, guidance for performance improvement strategies in aspects of the dissatisfied area is also provided. Application of this approach would assist in maintaining the long-term value for money of social infrastructure PPP agreements.

    Understanding the Green Building Industry in Thailand
    Shen, W ; Tang, W ; Siripanan, A ; Lei, Z ; Duffield, C ; Hui, K ; Gou, Z (Springer, 2020)
    Promoting green building has become a global trend to improve resource efficiency and well-being of societies. The aim of this study is to systematically investigate the key aspects of the green building industry in Thailand (i.e., critical successful factors, key green technologies, and barriers) and to provide a sound basis for deeply understanding the drivers of the industry. Based on a survey of consultants, architects, and engineers, the results show that critical success factors of green building are mainly related to competence of project participants, integration of project team, technical and management innovation, external environment, and project characteristics. The analysis of green technical capabilities demonstrates that project participants should emphasize improving technical skills in green building, use of green materials, and familiarity with green building rating systems. Barriers to green building mainly arise from financial pressure, technical limitation, and inadequate promotion. The findings can help project participants to adopt appropriate strategies in boosting green building in emerging markets of developing countries. Future studies should focus on levering the demand of the market, integrated green technology innovation, and management measures at project, organizational, and industrial levels.
