Modern methods of construction (MMC) and innovation negativism in the UK public sectorhttps://www.emerald.com/insight/content/doi/10.1108/BEPAM-06-2023-0108/full/html?utm_source=rss&utm_medium=feed&utm_campaign=rss_journalLatestThe recent failures and insolvencies of organisations related to the modern methods of construction (MMC) have gained increased attention and controversy across the UK construction sector. Such failures are linked to their inability to achieve an economy of scale and drive key clients to accept the MMC as an alternative to traditional methods. This paper aims to unravel whether a phenomenon of “innovation negativism” has manifested and is contributing to public clients' indecision towards broader MMC, whether this is only linked to past negative experiences formed after the Second World War or whether additional contributing reasons exist to influence adoption. This study focusses on exploring the decision-making of the UK public construction sector; therefore, this paper adopts a qualitative approach, utilising interviews with 14 carefully selected MMC experts, government advisors and public clients.

Exploring the critical success factors for adopting gamification in the Nigerian construction sectorhttps://www.emerald.com/insight/content/doi/10.1108/BEPAM-08-2023-0150/full/html?utm_source=rss&utm_medium=feed&utm_campaign=rss_journalLatestWith a view to ensuring the effective and efficient delivery of construction projects, this study evaluates the critical success factors (CSFs) for the adoption of gamification principles by construction professionals in developing countries, with an emphasis on Nigeria. This study adopted a post-positivism philosophical approach, using a questionnaire survey to obtain quantitative data from 126 construction professionals in Lagos State. The data obtained were analyzed using frequencies, percentages, mean item scores (MIS), Kruskal–Wallis H-test and principal component analysis (PCA) as part of the exploratory factor analysis (EFA). The findings indicated that the most significant factors for the adoption of gamification principles in the construction industry were “clear game mechanics and rules,” “incentives and rewards for users,” “secure and reliable technology infrastructure,” “real-time progress tracking and feedback” and “clear and measurable objectives.” Employing factor analysis, these CSFs were subsequently grouped into three primary clusters, namely “relevance and user experience,” “technology and support” and “integration and process.” These findings not only enrich the existing theoretical framework but also provide a solid foundation upon which researchers can build for further theoretical development. This study also offers valuable insights that can inform and improve practical applications of gamification within the construction industry. While prior research has explored gamification in various contexts, the unique contribution of this study is the thorough investigation of CSFs for gamification adoption specifically within the construction industry. In essence, this study fills a critical gap in the literature by offering fresh perspectives and tailored solutions for the construction industry's specific gamification needs.Exploring the critical success factors for adopting gamification in the Nigerian construction sector

Ex ante required rates of return and related factors in Indonesian PPP infrastructure projectshttps://www.emerald.com/insight/content/doi/10.1108/BEPAM-06-2023-0113/full/html?utm_source=rss&utm_medium=feed&utm_campaign=rss_journalLatestThis paper delves into the ex ante rates of return demanded by the private sector in Indonesian public–private partnership (PPP) infrastructure projects and the manifold factors emanating from project attributes that can influence these rates. This paper analyzes feasibility studies of 37 PPP projects across different sectors. The studies were carefully selected based on relevance, completeness and validity of data. The analysis uses statistical techniques, including Levene’s tests, t-tests, ANOVA tests, Cohen’s effect size and Pearson correlations, to explore differences in cost of capital and excess returns across various attributes. Based on the statistical analysis, no significant difference exists between the excess return of 200 basis points (bps) and the equity excess return of 0 bps. This suggests that the eligibility criteria for PPP projects require an internal rate of return (IRR) equal to the weighted average cost of capital plus 200 bps or an equity IRR equal to the cost of equity. The variations in the tested variables among diverse project attributes do not exhibit statistically significant disparities, even though specific attributes display moderate to high effect sizes. This paper represents one of the first attempts to examine the rates of return demanded by the private sector in the context of Indonesian PPP projects. It comprehensively explores the factors that influence these rates, drawing on insights derived from feasibility studies.Ex ante required rates of return and related factors in Indonesian PPP infrastructure projects

This study employs a case-based method for identifying PCFs and a DEMATEL method for analyzing the interdependence of complexity factors in metro rail projects.

To validate and refine these factors, semi-structured interviews were conducted with thirty experienced professionals, each having 5–20 years of experience in roles such as project management, engineering, and planning. Further, elevated and underground metro rail projects were purposefully selected as cases, for identifying the similarities and differences in PCFs.

The current research study adopted a quantitative research method. Using a purposeful sampling strategy, 100 construction companies engaged in small construction projects in Sri Lanka were selected and a questionnaire was distributed among top managerial employees of these companies. Employees belonging to 47 companies responded to the survey which provided information relating to 812 construction projects. The collected data were analyzed using the RM implementation index (RMII) and other quantitative measures such as mean, median and percentages.

Prioritizing the principles of circular economy among built environment professionalshttps://www.emerald.com/insight/content/doi/10.1108/BEPAM-04-2023-0077/full/html?utm_source=rss&utm_medium=feed&utm_campaign=rss_journalLatestCircular economy (CE) is guided by principles, the key being the R-framework. All R-frameworks have a hierarchy. Although several studies have prioritized these principles, there is still an urgent call for country-specific prioritization. This study prioritized circular economy (CE) principles among Ghana's built environment (BE) professionals. An explanatory sequential mixed methods approach was adopted. Six principles of CE were identified through a review of related literature and incorporated into a questionnaire. In total, 162 questionnaire responses were received. The quantitative data were analyzed through descriptive and inferential analyses. The data were further validated via semi-structured interviews with eight interviewees of different professional backgrounds in the BE. The findings revealed that BE professionals in Ghana highly perceived CE principles as important. The findings further revealed the order of prioritization of the CE principles as follows: (1) recycle, (2) reuse, (3) repair/remanufacture, (4) renewable energy usage, (5) redesign and (6) reduce. To further elaborate on these prioritized principles via the qualitative phase, the interviewees agreed to and confirmed the importance of the identified principles through their verbatim comments. Although there is a growing interest in research regarding CE in the Ghanaian construction industry, its principles have yet to be prioritized and ranked by professionals in the Ghanaian construction industry. This study unearths why, in terms of prioritization of the CE principles, the construction industry in Ghana does not follow the well-known hierarchy (i.e. reduce, reuse and recycle) in the order of high to low level of circularity.Prioritizing the principles of circular economy among built environment professionals

The research, grounded in a thorough literature review, identifies critical gaps in these areas and examines the extent to which PC moderates the effects of AR, AS and SE on PP, offering new perspectives for managing complex projects. The research develops a conceptual model based on a critical analysis of existing literature. A comprehensive questionnaire was designed, incorporating 28 items to measure AR, AS, SE, PP and PC. Data was collected from 136 project managers across various industries, and the responses were analysed using structural equation modelling (SEM) to explore the complex interplay between these variables. The analysis revealed that internal AR (ARint) significantly enhances both quantitative (PPqt) and qualitative aspects of PP (PPql). AS and SE were found to positively influence PPql, but their impact on PPqt was not significant. Interestingly, PC was observed to negatively moderate the relationship between ARint and PPql, while its moderating effect on the relationship between ARint and PPql was not significant. The study also notes that PC does not significantly alter the positive correlations between AS, SE and PPql. This research contributes to the existing body of knowledge by elucidating the relationships between ARint, AS, SE and different dimensions of PP. It uniquely explores the role of PC as a moderating variable in these relationships, offering valuable insights for practitioners and researchers in the field of complex project management.Optimising project outcomes in complex environments: empirical insights on agile practices and stakeholder dynamics

The significance of effective management of handover information is highlighted by global building failures, such as the Grenfell Tower fire in London, UK. Despite existing technological interventions, there remains a paucity of understanding regarding the factors contributing to the decline in the quality of handover information during the post-construction phase.

Building on these insights, the study performed a mapping exercise to align these identified factors with blockchain technology features and information quality dimensions, aiming to evaluate blockchain’s potential in managing quality handover information. The study findings suggest that blockchain technology offers advantages but has limitations in addressing all the identified quality issues of managing handover information.

Analysing resilience and leagility in post-pandemic sustainable supply chain management: a systematic literature reviewhttps://www.emerald.com/insight/content/doi/10.1108/BEPAM-10-2022-0151/full/html?utm_source=rss&utm_medium=feed&utm_campaign=rss_journalLatestThis study aims to comprehend the role of leagility and resilience in developing sustainable global supply chains, mitigating short-term disruptions and long-term economic impacts from various disasters, in the context of Australian civil infrastructure projects. The study employs systematic review approach to establish that addressing project success dimensions (i.e. leagility, resilience and sustainability) requires an integrated and extended supply chain approach, encompassing traditional supply chain strategic model elements (i.e. cost/capital, quality and service goals) and supply chain eco-system (i.e. organisations, societies, economies and nature). The study underscores the need to enhance supply chain leagility and resilience to achieve sustainability. This can be achieved by developing skills needed to plan across project phases and time frames, aligning with short and long-term organisational goals, assuming smart risks in the face of uncertainty. This study extends the traditional supply chain strategic model by introducing new priorities to minimise the consequences of disruptions and to effectively respond to them. The integration of leanness, agility and resilience ensures a sustainable supply chain even in the times of uncertainty, disruption and volatility. This research provides an opportunity for practitioners and policymakers to rethink and redesign the conventional supply chain model of cost, capital, quality and service objectives. It introduces pioneering concepts by acknowledging and incorporating emerging priorities, especially in Australian civil infrastructure projects. The study integrates leagility and resilience into the existing strategic framework, adding crucial dimensions for sustainable supply chains in infrastructure companies.Analysing resilience and leagility in post-pandemic sustainable supply chain management: a systematic literature review

Good practices in COVID-19 risk reduction adopted by Australian construction enterpriseshttps://www.emerald.com/insight/content/doi/10.1108/BEPAM-10-2022-0154/full/html?utm_source=rss&utm_medium=feed&utm_campaign=rss_journalLatestThis research investigated the impacts of COVID-19 on construction enterprises and good practices adopted by the enterprises in reducing COVID-19 risks. The Sendai Framework (TSF) is widely accepted as a strategic roadmap to reduce disaster risks throughout the life cycle of a disaster. As such, with the aim of enhancing the resilience of Australian construction enterprises, the identified good practices were mapped with TSF priorities to consolidate COVID-19 risk reduction practices that can be adopted by Australian construction enterprises. Case study research approach was used, and three case studies were conducted with small, medium and large construction enterprises. Small, medium and large enterprises were selected based on the Australian Bureau of Statistics classification of the business size. Data were collected through semi-structured interviews conducted with three executive members from the three enterprises. Data were analysed using content analysis. The study found that construction enterprises faced demand and supply side impacts. Infrastructure projects, funded by public sector clients and larger enterprises were least affected. Investments and demand for residential and other building projects were reduced by private sector clients, affecting small and medium enterprises. Findings also show that the construction enterprises adopted good practices in identifying, managing, investing on resilience and recovery that align with TSF priorities. All three enterprises agreed on some common good practices on risk identification, risk management and effective recovery. Different views were shared on investments related to disaster resilience. This study contributes to mitigate the COVID-19 impacts on construction enterprises and subsequent economic and social impacts. This research found how Australian construction enterprises survived during COVID-19. The study adopted TSF to construction and COVID-19 context while consolidating COVID-19 risk reduction practices.Good practices in COVID-19 risk reduction adopted by Australian construction enterprises

With increased concerns from stakeholders on sustainability related issues, from environmental to socio-economic perspective, managing megaprojects has become quite challenging. Hence, there should be proactive approaches in active engagement of stakeholders from the start of the projects to overcome such issues. Currently, there is a knowledge gap on stakeholder management strategies specific to megaprojects on managing sustainability issues. This research has adopted review of secondary data from case studies to identify stakeholder management challenges and strategies in megaprojects around Sydney area.

Moreover, significant sectors and strategies have been identified for key focus to manage environment and socioeconomic issues. Whatever be the strategies, in case of megaprojects, they need to be mostly proactive. This research has extended the knowledge on stakeholder management, in relation to managing sustainability-related issues of megaprojects during their design, construction and operation phases.
