A Systematic Literature Review on Disruptions in Construction Supply Chain: Some Stylized Trends
No full textConstruction supply chains (CSC) are intricate systems characterized by fragmentation and inefficiencies, which have been exacerbated by external disruptions such as the COVID-19 pandemic, natural disasters, and geopolitical instabilities. These challenges underscore the urgent need for resilient and adaptive supply chain strategies that integrate emerging technologies. However, existing research remains fragmented, lacking a comprehensive framework that aligns digital innovations with broader operational, economic, and stakeholder considerations. To bridge this gap, this study employs a systematic literature review (SLR) complemented by natural language processing (NLP) techniques to analyze existing knowledge on CSC disruptions and resilience-building strategies. A total of 63 articles were reviewed, with thematic clustering and topic modeling applied to uncover key challenges and opportunities. Findings reveal two primary clusters: macro-level strategies focused on systemic resilience and micro-level solutions addressing operational inefficiencies. The results indicate that while Industry 4.0 and modular construction methods offer promising solutions, their integration into CSC frameworks remains inconsistent. By combining qualitative SLR insights with quantitative NLP analysis, this study provides a holistic perspective on CSC disruptions and potential resilience strategies, offering valuable implications for both academia and industry. In particular, it might support practitioners in identifying suitable solutions for material tracking and in turn reducing inefficiencies. In addition, the issue of collaboration and information sharing is stressed in order to achieve a more aware decision-making process and reduce the level of uncertainty with a consequent higher resilience along the supply chain in the construction industry
Multiple Linear Regression Model for Project’s Risk Profile and DSCR
No full textSeveral studies have been conducted in the field of project risk management to understand the bankability
criteria for PPP projects. However, the relationship between risk factors and financial variables requires increasing
analysis for project finance projects such as Public-Private Partnerships (PPPs). Debt providers may benefit by
understanding how project risk impacts debt financing ratios. This study focuses on identifying the main factors that may
influence the target Debt Service Coverage Ratio (DSCR). To achieve bankability, PPPs must demonstrate that the
minimum DSCR is greater than or equal to the target DSCR pre-established. In this study, potential factors that may
affect the DSCR are analyzed, namely: demand revenues, debt/equity ratio, repayment period, concession period,
CAPEX, interest rate, rate of return, public subsidies, and construction period. This study aims to develop a linear model
and an analysis of variance to understand how risk profile variables affect the DSCR established by debt providers in
PPPs. The research is based on a dataset of six hospital PPP projects in PPP healthcare facilities. The regression model
presented brings to the fore the correlation between the internal rate of return and the target DSCR. The Repayment
period also demonstrated correlation but with lower significance. The reliability of the model is strongly dependent on
the data taken into account for some Italian PPP projects. The analysis shows that it is potentially acceptable for debt
providers to reduce the target DSCR based on a high IRR
Crisis management in public–private partnerships: lessons from the global crises in the XXI century
Full text linkPurpose: Global crises have become increasingly recurrent events that jeopardize public-private partnerships (PPPs). In this context, the purpose of this paper is to expose the PPP-crisis research agenda by combining bibliometric and network analyses. Design/methodology/approach: The PPP literature associated with global crises between the 2008 global financial crisis and 2022 was analyzed in three stages: (1) paper selection and screening for the inclusion/exclusion of articles relevant to this research, (2) semantic network development for examining thematic relationships among selected papers by considering the co-occurrence of keywords within the chosen studies and (3) calculation of network metrics for analysis. Findings: The paper identified six research avenues for the PPP-crisis agenda: public interest, relational governance, risk management, user-pay PPPs, crisis management and financial performance. The PPP-crisis literature has spread significantly in the last five years driven by the case study approaches on a national or regional basis. Conversely, non-crisis periods generate room to strengthen user-pay PPPs and relational governance. The pandemic and post-pandemic times shared the priorities of the 2008 financial crisis but also strengthened the management of the risks and the structural drivers of the global crisis. Originality/value: This study demonstrates that during global crisis periods, the public interest and financial performance gain relevance in a detriment of structural solutions to social legitimacy erosion of PPPs because of the urgency of giving tools to the public and private sectors to tackle the financial issues, which steer future issues for PPPs
Impact of Integrated Supply Chain Platforms on Construction Project Management
No full textSupply chain challenges in the construction industry often lead to cost and time overruns, making it imperative to enhance supply chain management. To offer a tool to construction decision-makers, this study investigates the impact of Integrated Supply Chain Platforms (ISCP) on construction project management in the context of Nordic European countries by exploring the effectiveness of integrated software platforms and their influence on project outcomes, focusing on time, cost, and risk management. Utilizing Structural Equation Modeling, the study examines the interplay between ISCP adoption, time management, cost management, and risk management. Results indicate a high satisfaction level among ISCP users, particularly in risk, time, and cost management. The structural equation model analysis demonstrates the positive influence of ISCP adoption on risk and time management, indirectly affecting cost management and overall project performance. The study identifies the significance of prolonged ISCP adoption in improving risk and time management. While ISCP does not directly impact cost management, its indirect influence, mediated through time management, enhances project performance. The findings contribute to understanding the role of digital technologies in optimizing construction supply chains, emphasizing the need for specific sub-frameworks for digital supply chain implementation in the construction industry
Financial system dynamics model for multidimensional flexibility in toll road PPPs: a life-cycle analysis
Full text linkAlthough scholars have developed simulation models and analyzed bankability criteria in numerous papers to enhance the financial outcomes of Public-Private Partnerships (PPPs), the intersection between both fields considering alternatives to assess the financial impact of flexibility in both scope and financing, remains underdeveloped. To address this gap, this paper introduces a financial model that assesses the financial impact of suitable life-cycle flexibility alternatives while coexisting with revenue performance alterations in each project phase within toll road PPPs. This model serves as a tool to gain insight into the planning of strategic actions to implement flexibility in both scope and financing. Based on system dynamics and validated using financial data from two toll road PPPs in India and East Europe, simulation results suggest that two key drivers (capital expenditures and debt repayment period) have the greatest influence on financial performance. Findings support the implementation of flexible scopes to effectively address the most influential exogenous factor impacting the financial performance of PPPs, namely traffic shortfalls. This model provides a suitable tool for assessing the life-cycle economic sustainability of PPPs in uncertain and complex environments
Building Information Modeling for Risk Management: A Literature Review
No full textBuilding Information Modeling (BIM) has become more relevant to the construction industry in recent years due to almost all of the biggest industries use BIM as a tool to improve the integration process and risk management. Although there is significant literature on risk management and BIM, the relationship between both of them has not been covered in previous research. This study provides a thorough explanation of the relationship between the interaction with risk management and BIM, as well as how it has evolved. Following a screening procedure, 190 peer-reviewed papers were pulled from the Scopus database. Findings showed that the introduction of risk management into BIM is still in an incipient phase within the construction project management body of knowledge. Overall, three developed nations—the USA (with 30 documents), Australia (21) and China (21)—have steered this research agenda, while a developing country—Malaysia (17)—is an outsider gaining relevance as the fourth contributor to this topic. Five clusters were identified by the network representation, these clusters include risk and project management areas that constitute the research paths to be advanced in the next few years
Advancing Collaborative Water Governance: Unravelling Stakeholders’ Relationships and Influences in Contentious River Basins
Full text linkCollaborative water governance (CWG) has emerged as a promising framework to tackle water management challenges. Simple identification of participants however is not enough to unravel the intricacies of stakeholders’ interlinkages, roles and influences for robust CWG. A clear understanding of the stakeholders’ landscape is therefore required to underpin CWG. In this work, we combine stakeholder analysis (SA), social network analysis (SNA) and participatory processes (PP) under a theoretical collaborative governance framework to advance CWG in the contentious Rapel River Basin (RRB), Chile. By combining these techniques, we identified a cohort of leading (and secondary) stakeholders, their relationships and critical roles on basin-wide CWG-enabling networks (collaborative ties, information flows and financial exchanges) and their influence to achieve a shared vision for water planning. The results show members of this cohort perform critical roles (bridging, connecting and gatekeeping) across the networks and in influencing explicit elements of the shared vision. Specific CWG-enabling networks properties indicate a weak adaptive capacity of stakeholders to deal with potential water management challenges and strong prospects for sharing innovative ideas/solutions and achieving long-term water planning goals. A major CWG implementation challenge in the RRB is the lack of a leading organisation. One way forward would be formally organising stakeholders of the identified cohort to advance CWG in the RRB. By implementing the methodological framework, we facilitated social learning, fostered trust among stakeholders and mobilised efforts towards implementing CWG in practice in the contentious RRB
Social Legitimacy Challenges in Toll Road PPP Programs: Analysis of the Colombian and Chilean Cases
Full text linkPublic-Private Partnership (PPP) programs have been developed widely for more than 30 years across the world. The continuity of these programs depends on an adequate balance of three-dimensional sustainability (i.e., economic, environmental, and social). Nevertheless, social sustainability has been demonstrated as being fragile because of the challenges to achieving the intended social legitimacy in PPP programs. This study aims to understand key challenges in achieving social legitimacy in road PPP programs by analyzing contractual clauses, legal frameworks, and stakeholders' interviews of two toll road PPP programs in Chile and Colombia. Three key challenges to social legitimacy were found: social involvement issues, distrust between impacted and responsible stakeholders, and lack of social criteria within toll tariff policy. Findings reveal that it is required to move beyond current consultation mechanisms and thoroughly involve the impacted groups as a relevant stakeholder typology in order to maximize value creation in user-pay PPP programs. In line with that, this study exposes that the claim of previous research for developing relational governance between the public and the private sectors is not enough for overcoming governance limitations and addressing social legitimacy in user-pay PPPs. It is also necessary to enhance relational governance in a triadic approach. This study contributes to the PPP body of knowledge by redirecting the discussion from overall legitimacy to social legitimacy challenges and by including the impacted stakeholders in the analysis of PPP governance mechanisms
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
