    Improving design performance by alliance between contractors and designers in international hydropower EPC projects from the perspective of Chinese construction companies
    Zhang, Q ; Tang, W ; Liu, J ; Duffield, C ; Hui, FKP ; Zhang, L ; Zhang, X (MDPI AG, 2018-04-13)
    © 2018 by the authors. Extant literature lacks a systematic framework addressing the mechanisms of the alliance functional process and its impacts on management activities together with performance in delivering Engineering-procurement-construction (EPC) projects. This study quantitatively investigates the cause-effect relationships among these themes by building and validating a conceptual model of contractor-designer alliance in international hydropower EPC projects. With the support of data collected from an industry survey, the results reveal the key design problems, application of contractor-designer alliance, design management level and performance, which form a sound basis for design management emphasis in EPC activities, e.g., sufficiently considering sustainability of hydropower projects by incorporating environmental, social, and economic factors into designs. The path analysis indicates that the contractor-designer alliance can not only improve design performance by enhancing design management, but also directly promote design performance. This research has significant contributions to the body of knowledge by building interdisciplinary linkages between the areas of alliance, design management, and performance, theoretically demonstrating the mechanism of how interfirm cooperation functions to achieve superior design outcomes of hydropower EPC projects. Understanding these causal relationships will be crucial for contractors and designers to optimally allocate their complementary resources for seeking better design solutions in dealing with both technical issues and sustainability factors.

    Qualitative Analysis of the Occupational Health and Safety Performance of Chinese International Construction Projects
    Lei, Z ; TANG, W ; Duffield, C ; Zhang, L ; Hui, K ; You, R (MDPI AG, 2018-11-22)
    Chinese contractors undertaking international projects are frequently criticized for their poor Occupational Health and Safety (OHS) performance. It is noticed that people with different occupations may perceive OHS differently. From a qualitative perspective, this study investigates the perceived OHS performances of design managers and construction managers engaged in Chinese overseas construction projects, considering a range of subgroups classified by people’s overseas experience, project size, project industry, project location, and firm size. The analysis was based on an e-questionnaire survey that sampled responses from 52 design managers and 160 construction managers involved in 110 international projects, and face-to-face interviews with 26 managers. The findings indicate that the assessment variation of OHS performance between design managers and construction managers is not only related to their different mental ways, but also can be mediated by their in-progress communication and affected by project and organizational conditions. The varying OHS performance in projects with different sizes or from different regions also suggests that Chinese contractors should be more proactive in OHS management instead of passively responding to external requirements.

    Proceedings of the Port Competitiveness and Financing Research Workshop
    Hui, K ; Duffield, C ; Wilson, S ; Hui, K ; Duffield, C ; Wilson, S (University of Melbourne, Department of Infrastructure Engineering, 2018-04-10)
    Preface As an initiative of The University of Melbourne and partner universities, The University of Gadja Mada and Universitas Indonesia, a workshop of port researchers and senior practitioners was convened in Melbourne from 4th April to 6th April 2018. The researchers and practitioners have been brought together as a part of the Infrastructure policy and finance research being undertaken under the auspice of the Infrastructure Cluster Agenda of the Australia Indonesia Centre. This set of proceedings collates the presentations on the research day of the workshop conducted on the 4th April 2018. The researchers have been considering infrastructure and finance associated in improving port efficiency in situations where the port directly interfaces with a major city. The researchers have collectively critically reviewed the international literature, conducted surveys in Indonesia and Australia, conducted focus group meetings in Indonesia and Australia, conducted in‐depth interviews, participated in field trips to major port establishments and explored a range of case study projects in both countries. This workshop created the opportunity for researchers to seek opportunity to syntheses their collective research.

    The Risk of Power Imbalance in Project Delivery: A Study of Large Victorian Public Infrastructure Projects
    Zarei, H ; Hui, K ; Duffield, C ; Wang, G (Atlantis Press, 2017)
    In large public infrastructure projects, political risks due to the power imbalance between central and delivery agencies are often overlooked or underestimated. The primary motive of the delivery agency in distorting information for political gains should be deemed a risk that creates uncertainty for large projects planning the outcome. In this study, seven large infrastructure projects in the state of Victoria, Australia are examined through a workshop involving key stakeholders who had played active roles in these projects. The findings revealed that power asymmetry between central and delivery agencies exist and would lead to optimism bias, which in turn creates uncertainty and risk of overpromising in the business case. Power asymmetry exist in large infrastructure projects because the central agencies usually only have the responsibility but not the skill set needed to measure the robustness of the business case. These types of political risks are difficult to quantify and even detect. This paper recommends a few managerial strategies that have referential values and/or can be used to mitigate and circumvent this risk.

    CAUSES OF CONTRACTORS' CLAIMS IN INTERNATIONAL ENGINEERING-PROCUREMENT-CONSTRUCTION PROJECTS
    Shen, W ; Tang, W ; Yu, W ; Duffield, CF ; Hui, FKP ; Wei, Y ; Fang, J (VILNIUS GEDIMINAS TECH UNIV, 2017)
    Engineering-Procurement-Construction (EPC) method has increasingly been applied in international markets. In this research, the causes of contractors’ claims in international EPC projects are modeled and empirically tested with industry survey, structural equation modeling and case studies from the perspective of Chinese contractors. The estab­lished model outlines the causes of contractors’ claims as: external risk (sociopolitical risks, economic risks, and natural hazards), clients’ organizational behavior (untimely payment, change orders, and inefficient processing), and project definition in contract (unclear scope of works, and unclear technical specification). The structural equation modelling validates that these causes have direct influences on claim respectively. Besides, clients’ organizational behavior acts as a partial mediation between external risk and claim, demonstrating that external risk can also exert influence on claim through affecting clients’ organizational behavior. Seven case studies further confirmed and interpreted the substantive meaning of these relationships. This study establishes interdisciplinary linkages among knowledge areas of contracting, risk management, organizational behavior, and international EPC project delivery, which has important primary contri­butions in both theory and practice. Understanding how the fundamental factors interactively lead to claims can help contracting parties to develop effective claim strategies, proactively mitigate project risks, and ultimately improve EPC project performance.

    Why may public infrastructure projects over-promise likely outcomes?
    Zarei, H ; Duffield, C ; HUI, K (Australian Institute of Project Management, 2016-11-01)
    The prevailing approach to measure project success compares an ex-post outcome with the ex-ante plan. Comparisons of project success are often questioned, and actual success is unlikely to realised if the initial plan is excessively optimistic such as exaggerated benefits, overlooked risks, and unrealistic assumptions. Published literature suggests that technical inadequacies of estimation models, psychology of human mind, economic obligation for risk, and organisational misrepresentation may be factors that can explain this planning fallacy in projects. Nevertheless, these explanations are considered lacking as they do not adequately address the complexity of infrastructure project decision process. This paper goes beyond planning fallacy in a quest for a better explanation. A workshop of project experts was convened to test the earlier understandings relating to behaviours exhibited during the initiation of an infrastructure. Importantly it framed much of the interactive dialogues among participants around seven case study projects that were considered in the 2012 Parliamentary inquiry of the committee of the Public Accounts and Estimates Committee (PAEC) that explored the effectiveness of decision making in Victorian infrastructure delivery. It emerged that one of the key behaviours was considered to be the use of power in decision-making during project initiation. Power manifests as the ability to influence others’ intent. In projects, its root lies in information, expertise, authority, legitimacy, and reputation. The notion of power has been recognised as a fundamental concept to explicate the behaviour of actors in a collaborative environment. This paper focuses on the delivery process of public infrastructure projects and investigates the asymmetry of power among participants in an attempt to unravel the complexity of decision authorities and delegations. In a conceptual isolation of central agencies from delivery agencies, a new concept of informal authority is devised to provide a reliable explanation of how delivery agency’s optimism may pay off in the presence of an asymmetric distribution of power. The paper concludes that power asymmetry is a critical success factor in public infrastructure projects and makes suggestions for future improvements.he prevailing approach to measure project success compares an ex-post outcome with the ex-ante plan.
