Employing a mixed-methods approach, the research systematically examines the key features, benefits, and limitations of PFI, BOT, and JV models in the context of SSID. A compatibility assessment is conducted, focusing on financing approaches, stakeholder engagement, and other critical success factors. The findings reveal that the BOT and JV models are superior to the PFI model due to their balanced stakeholder engagement, risk sharing, and alignment with critical success factors. Based on these insights, the study formulates novel, customised recommendations for optimising the selected model's efficiency, effectiveness, and compatibility with SSID in Sri Lanka, with the aim of informing policy and practice. Furthermore, the study highlights the need for future research exploring alternative financing models and emerging technologies in SSID, opening new avenues for innovative approaches to infrastructure development in Sri Lanka.

Indeed, IS integrates the complexity of industries encouraging the use of materials and by-products as feedstock sources instead of being wasted. Digital technologies in CE transition have obtained significant attentiveness in academic research in last decade. However, while studies on the concepts of IoT, CE and IS have increased, there is a deficiency in research that systematises the literature for refining the importance of the intersection of IoT and IS in building construction. Thus, the purpose of this research is to conceptualise a IoT-enabled IS model for construction material sharing through Scopus-based systematic review of key literature. The journal articles published in Scopus database related to the fields of CE, IoT and IS were reviewed to understand their intersection towards construction material sharing. Systematic review outcomes were analysed using bibliometric analysis technique. The evolution of the publications, leading journals and authors who published the most papers on the intersection of CE, IoT and IS were mainly reviewed and a IoT-enabled IS model for construction material sharing in construction industry was conceptualised as the key implication of this research. The next stage of the research is to develop a generic symbiotic prototype for IoT-enabled construction material sharing between building construction projects, which can be applied in any context subjected to context specific enhancements.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"27 19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116130770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building resilience among the physical structures, infrastructure, and communities has become a necessity to improve the capacity to face future disasters. Effective utilisation of resources is one of the possible ways of building capacity within communities with the perception of enhancing resilience to future disasters. Therefore, identifying the correlation between resilience, capacity building, and resource utilisation is highly important to face future calamities. The resources required for enhancing disaster resilience vary depending on the type of disaster and the area affected by the disaster. Hence, resource constraints have been acknowledged as a factor in the ongoing failure of numerous recovery efforts. As such, capacity must be developed by utilising the resources effectively to address the deficiencies in resilience levels. Thus, a narrative literature review was carried out to establish the resource requirement in terms of capacity building to form disaster resilience. As the outcome of this comprehensive review, a conceptual framework was developed to support future decision-making processes with regard to disaster resilience. As per the findings, resource requirements exist in different forms such as infrastructure, institutional, economic, social, and environmental, and addressing them collectively, one after the other will enhance the resilience to future disasters in a considerable manner.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121346699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Apart from aiming to become a new economic generator for equal distribution of the national economy, smart and sustainable IKN is expected to trigger new styles of learning, working, and living and encourage a change in Indonesia's development paradigm. IKN covers a total area of 256,000 hectares, with approximately 56,000 hectares of planned urban built areas will be conducted in five stages from 2022 until 2045. One of the challenges faced by the construction phase in IKN is that the existing seaports in Handil and Muara Samboja still cannot provide the support required for the logistics supply of construction materials. To support the development of the IKN, the current seaports and supporting infrastructure must be developed to allow the seamless operation of the logistics process. Therefore, this study aims to propose a conceptual design for logistic seaports in the Simpang Samboja and Muara Jawa areas. Case study is the method used in this study, using both qualitative and quantitative approach. This case study method references previous studies to obtain alternative value-added components. The results of this study show that the proposed logistic areas can facilitate logistic supply in IKN development with value for money.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129009703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It includes a system of beliefs and philosophical assumptions that shape the understanding of the research questions and underpins the choice of research methods. Additionally, research methodology is an integral part of any research and helps to ensure consistency between chosen tools, techniques, and underlying philosophy. Therefore, this article shows the perspectives to choose the most effective methodology to increase the inclusion of marginalised communities during the post-disaster phase in Sri Lanka. A systematic literature review comprising of 61 articles adopted as the best-suited methodology for this research. The philosophical position of this research is interpretivism, whereas the abductive approach is utilised for theory development. Hence, more than one qualitative data collection method is used, and this research adopts a multi-method qualitative approach. Furthermore, case study and survey strategies are chosen as the most suitable strategies for this research. Two Grama Niladhari divisions affected by natural disasters in Sri Lanka are selected as the cases. Data collection techniques adopted in this research are literature review, structured interviews, desk study, stakeholder interviews, key informant interviews, focus group discussions, and expert validation interviews. Data analysis techniques are literature synthesis, relative importance index, stakeholder analysis, and code-based content analysis. Furthermore, the article discusses how researchers achieve the reliability and validity of research findings and ethical considerations.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132569875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Circular Economy (CE) and the adoption of its principles are currently recognised as one of the options to address these unsustainable issues. Despite, these principles are represented differently within three main domains: (1) collections of R-imperatives or R-framework, (2) CE loops, and (3) the ReSOLVE model, makes it a challenge for embracing CE principles in the building sector. A systematic literature review was carried out to respond to the research question \"What are the R-imperatives that are applicable for the building sector as CE principles?\", using Preferred Reporting Items for Systematic Reviews (PRISMA). It yielded a total of 23 papers to analyse. This review confirms that although alternative domains exist, the most practical CE principles seem to be confined to R-imperatives. The study provides 17 R-imperatives in the descending order of their circularity, along with their definitions. Finally, these R-imperatives are logically linked with principles of other two CE domains. This would provide a clear understanding of CE principles and thereby enable CE applications in the building sector.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130460544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, financial, cultural, infrastructural and technological barriers hinder the implementation of digital twin. Researchers have emphasised the importance of considering both visible and invisible barriers of digital twin implementation. ‘Lean Iceberg Model’ (LIM) emphasises that most of the underlying barriers and problems in a project are invisible and unaddressed, and it is critical to solve these underlying issues to achieve effective implementation. The study aims to develop a LIM to minimise barriers for successful digital twin implementation in the Sri Lankan construction industry. This study adopts an interpretivism stance and employs a qualitative research approach. Semi-structured interviews were conducted with 15 experts chosen through purposive sampling. VBA script was employed to analyse the data. LIM highlights the unseen aspects such as leadership, commitment, employee engagement, and organisational strategy as crucial to the successful digital twin implementation. Thus, a comprehensive approach is required to contemplates the technical aspects with the organisation's overall strategy, employee engagement, and leadership commitment. Moreover, cultural values, norms, leadership, and social networks are also examined to determine their impact on digital twin implementation. A framework for minimising the barriers to the implementation of digital twins in the Sri Lankan construction industry using the LIM has been developed incorporating the findings, which will offer valuable insights for construction industry professionals and policymakers interested in implementing digital twin to improve construction project management.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127132400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transforming from the traditional linear supply chains into a circular arrangement while thinking from ‘grave-to-cradle’ is a value-adding approach to managing DW effectively. Consequently, the concept of ‘reverse logistics supply chains (RLSC)’ has captured the attention of the construction industry. However, the poor quality of re-processed products has hindered the successful adoption of RLSC in the construction industry. Therefore, this study examines aspects of the quality assurance system needed for RLSC to manage DW effectively and efficiently. The study used a qualitative approach, including 20 semi-structured interviews with internal stakeholders of the RLSC of DW. The study empirically confirmed that the RLSC of DW should embrace an integrated system for QA, including four aspects: process, people, policy, and technology. Under process for QA, standard practices are to be undertaken separately during building dismantling and off-site waste processing stages. While people in RLSC are skilful, competent, licensed, supervised and monitored, internal and external organisational policies should also be available for QA. Besides, espousing traditional practices with innovative technologies is also imperative for QA in RLSC of DW. The study makes a significant contribution by empirically proving that an integrated system of process, people, policy and technology is needed for QA in RLSC of DW. The developed quality assurance system provides useful insights for industry practitioners about the aspects that they should embrace in enforcing QA throughout the transformation from ‘grave-to-cradle’ in the construction industry.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129461575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the unique and complex characteristics are involved in a building project, the structure must be strong enough in terms of its durability, stability as well as the appearance. Accordingly, water is the most persistent opponent of a high-rise building, and gradually, building components might erode, compromising their structure and requiring costly repairs. Thus, the purpose of this study is to examine the factors that influence the choice of the best waterproofing system in high-rise building projects in the tropics. Semi structured interviews were used to determine how the factors affected the choice of waterproofing. All respondents were project managers or engineers with extensive backgrounds in the building sector and expertise in waterproofing. Collected data were analysed using manual content analysis. The taxonomy was created using the opinions of experts and contractors on the choice of waterproofing. The most important category in the Taxonomy was related to detailing technology, while the least important category was related to legal requirements and compliance.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115089800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
