To date, researchers and governments have paid increasing attention to the zero-waste goal as an effective solution to alleviate the environmental impacts of construction projects towards sustainability. Accurate estimation of construction waste is a prerequisite for an effective waste management plan to achieve zero-waste construction sites. In literature, various methods have been adopted to estimate construction waste generation at the project level. However, there is a lack of an evaluation of existing construction waste estimation methods at the project level in terms of the information that the methods can provide to facilitate construction waste minimisation in a construction project. Hence, a systematic literature review was conducted in this study to bridge the research gap. Twenty-eight papers were selected based on the PRISMA approach and categorised into five estimation methods: area-based waste generation rate, variables modelling method, bill of quantity-based classification system accumulation method, BIM-based classification system accumulation method, and other particular methods. The applicability of those methods to aid practitioners towards construction waste minimisation was analysed based on four aspects: design information requirements, the ability to use in the early design stage, project characteristics, and the ability of waste tracking by material type and construction element.

An Unsolicited Proposal (USP) is a privately initiated process that is an alternative to the solicited procurement method. Public Private Partnerships (PPPs) that are launched on an unsolicited basis, become popular among governments since they enable faster delivery of projects and avoid the time-consuming process of competitive tendering. If improperly managed, USPs may lead to numerous public rallies and protests, poor value for money, a failure to meet the nation's true sociological and economic necessities, and the satisfaction of only a handful of public and private officials. Most governments accept and recognise USPs by integrating various management systems into their procurement processes to mitigate the negative effects of it. Strengthening the existing legal and regulatory framework is one such management system. The authors conducted a detailed study of the existing legal and regulatory framework of countries that are having matured and developed PPP environments and a provision to entertain unsolicited PPPs. Based on the findings from the detailed study, a conceptual framework was developed for the procurement of USPs that can be utilised to reform existing legal and regulatory frameworks of host countries.

All over the world, environmental pollution has become a major environmental issue at present. As the construction industry extracts a high amount of natural resources compared to any other industry, it can be known as one of the significant causes of environmental pollution. In order to protect the environment from harmful human activities, there is a massive demand towards sustainable construction practices. Circular Economy (CE) concept has been identified as a way forward to sustainable construction practices. It has been identified that implementing CE in the construction industry has many barriers, enablers and drivers. Hence, this study aims to qualitatively analyse the relevance of the barriers identified through a literature survey in the global context towards circular economy implementation of the Sri Lankan context. Semi-structured interviews were carried out among industry experts and academics who have experience and knowledge of the CE concept. The findings of this study indicate that the practical implementation of CE in Sri Lankan built environment has many barriers as it is still in an early stage. This study concludes that the construction industry stakeholders should be aware of these concepts, and primarily the authorities should focus more on this concept to move forward with a sustainable construction industry and protect the environment.

Termination of construction contracts has significant impact on the construction industry. But none of the past literature has addressed on how termination can be managed effectively specific to Sri Lankan context given the unique cultural, economic, and legal contexts of Sri Lanka. Therefore, this research aims to investigate and provide practical strategies for managing the termination of construction contracts. Initially, the literature review provided an understanding of contract termination. Subsequently, this study used qualitative approach involving case study and expert opinion. Under the case study, the documentary review was conducted that focus on fifteen terminated building projects in Sri Lanka over the past five years to understand the termination phenomenon in Sri Lankan context. Finally, an expert opinion was obtained to gain deeper understanding of the findings. The collected data was structured through manual content analysis and descriptive analysis. The study found that Western and Northern provinces of Sri Lanka have higher termination rates due to urbanisation, and economic development. Complex approval processes, and bureaucratic inefficiencies are the common reasons for contract termination in commercial and residential building projects. Public projects are more vulnerable to termination due to political considerations. Employers are more likely to terminate contracts than contractors, possibly due to financial instability and higher quality expectations. Finally, combination of mitigation strategies should be customised to minimise the risk of termination. These strategies can be implemented with modifications to fit the local context, but challenges such as lack of awareness, bureaucracy, and resistance to change may arise.

Railway infrastructure is one of the core items of railway systems, which ensures the quality and efficiency of the service. As it appears, the railway infrastructure in Sri Lanka is not well maintained. This underperforming situation can lead to a considerable negative impact on the satisfaction of railway users. Hence, conducting an in-depth investigation on customer satisfaction in railway stations under railway infrastructure in Sri Lanka is a timely requirement. Thus, this study aimed to investigate the present customer satisfaction level at Sri Lankan railway stations. Specifically, this study focuses on improving customer satisfaction at railway stations based on the services and facilities provided. A comprehensive literature review has been conducted to review the railway infrastructure, Sri Lankan Railways (SLR), facilities and services provided by SLR, and factors that affect customer satisfaction. Further, data was collected through the distribution of a questionnaire survey among a sample of railway users. The quantitative research approach was undertaken to derive reliable outcomes with the support of RII analysis. As per the key findings, customer satisfaction on railway stations remains in a low to medium level based on several factors. The key issues recorded under the facilities and services of railway stations are delays in train arrival, uncleaned condition, and lack of data sharing.

The Sri Lankan construction industry is facing significant challenges in building construction projects due to the negative impacts of using traditional building materials. Consequently, there has been a surge of interest in sustainable materials, and among them, bioplastics have emerged as a promising alternative. The aim of this study is to investigate the potential of bioplastics as a sustainable building material specifically for the Sri Lankan construction industry. To achieve this, the study applied a qualitative research approach to collect data through semi-structured interviews. The research objectives are to identify alternative sustainable materials used in construction and identify how bioplastics could contribute to the construction industry as ta sustainable material. In addition to that, the study also identifies the motivators and challenges to the use of polymer building materials in Sri Lanka and subsequently develop a framework including potential strategies to use bioplastic as a sustainable construction material. The study's findings have identified significant factors that establish bioplastics as a sustainable material suitable for the Sri Lankan construction sector. Moreover, the research offers valuable recommendations to address challenges related to the adoption of polymer building materials. Furthermore, the study would contribute to the formulation of policies and regulations that promote the use of bioplastics as a sustainable building material.

The digital twin (DT) presents an opportunity for the integration of the physical world into the digital world. DT technology has the potential to transform the construction industry and respond to some of its challenges. In conventional construction projects, progress is largely monitored by direct observation and measurement which suffers from numerous challenges, including low productivity, blunders, and poor technology advancements. Concerns are now being raised about integrating technology for autonomously monitoring building activity. In other sectors, DT technology has been responsible for saving product development time and costs by up to 50%. However, DT is still lagging the adoption of new technologies in the construction industry. The overarching aim of this study was to explore the adaptability of DT in construction site progress monitoring. This study comprehensively reviews and analyses DT concepts, technologies, and applications in the construction industry, parameters of applications of DT in construction site progress monitoring, how DT could be used for site progress monitoring in construction, common challenges in the implementation of DT in site progress monitoring, and strategies such as barriers related to DT in site progress monitoring, using literature findings while incorporating qualitative analysis of semi-structured interviews. This research shows that DT has a high potential to solve the numerous challenges in construction site progress monitoring, rather than other current technologies in use. Thus, this study raises awareness and the need for the application of DT in construction site progress monitoring

The Smart Village (SV) concept can be mentioned as a potential enabler for rural area development by integrating smart technologies. Many developed countries adopted the Smart Village concept to develop their countryside for example “Digital Village” in Germany, the “Cowocat rural” project in Catalonia, etc. This has brought a key advantage called improved quality of rural life and public services. But in the Sri Lankan context, the evidence of the successful implementation of Smart Village for the development of rural areas is almost nil in parallel there is no significant development seen in rural areas. Thus, the study aimed to investigate the implementation, benefits, and challenges of using the Smart Village concept for rural area development in Sri Lanka. The mixed research approach was undertaken to accomplish the aim. A comprehensive literature review followed by semi-structured interviews was carried out with 07 experts knowledgeable in the Smart Village concept. The data were analyzed through the RII method and the manual content analysis. The results demonstrate, that the most implemented Smart Village feature in Sri Lanka is smart education, however, the most required Smart Village features are listed as smart connectivity and smart agriculture. Further, the technologies like ICT, AI, IoT, GIS, 5G, and smart grid can be adapted to raise the Smart Village concept covering agriculture, education, transportation, health, and infrastructure was presented. However, lack of network cooperation, difficulties in raising funds, and transitioning to low-carbon economies, were found to be the top key challenges in implementing Smart Village in Sri Lanka

The inverse relationship between the development of the construction sector and the preservation of the ecosphere is highly manifested by the excessive waste products resulting from the construction processes that are irrepressible by the existing waste management practices. Research has been conducted on utilising smart technologies such as blockchain technology and modern concepts such as the circular economy (CE) in enlightening waste management practices. Yet, the applicability of intervening the synergy of the two concepts of “blockchain-circular economy” is not adequately addressed in the existing literature from the perspective of effective construction waste management. Therefore, this study aimed at identifying the applicability of blockchain technology and circular economy in enhancing the effectiveness of construction waste management. Accordingly, a comprehensive literature review was conducted on the existing research on the enablers, barriers and strategies for the integration of the blockchain-circular economy, blockchain-waste management, and circular economy-waste management. The collected data were analysed using content analysis. The findings suggested that enablers such as supportive legislations and sustainability increments, barriers such as risks and lack of knowledge, and strategies such as introducing regulatory standards and adaption to technologies are common for the integration of the concepts. Accordingly, this study reveals the potential of assessing the practicability of integrating blockchain, circular economy and waste management in a common platform to establish resource optimisation in the construction sector

Banks play an important role in economic growth and social welfare enhancement. However, the COVID-19 epidemic had an unanticipated significant impact on enterprises and organisations. Nonetheless, due to the crucial nature of their services, banks should continue to operate. As a result, to increase efficiency and profitability, the banking industry has embraced cutting-edge technology and access techniques. One of the most popular methods in the worldwide banking sector is drive-thru banking. However, in Sri Lanka, no particular emphasis has been paid to this type of facility, and there has been no adequate study on this topic addressing the applicability of drive-thru banking facility. A detailed literature analysis was conducted to review the concept and important components of drive-thru banking, as well as elements of the banking business globally and regarding to the Sri Lanka. Case studies and a survey were used to continue the study using the qualitative research approach. The study examined how each of the implementation factors, such as enablers, barriers, benefits, limitations, requirements, and customer perspectives on this facility, affected the applicability. Accordingly, certain factors such as high initial costs, supplier and maintenance constraints, carparking limitations, queue control, and accessibility need to be addressed. The study concludes that by considering these implementation variables, drive-thru banking can yield positive outcomes for both customers and bankers. The study recommends that banks in Sri Lanka explore the potential of drive-thru banking facilities and adopt them as a means of improving their services and meeting customer needs in a changing landscape.

The study examined how each of the implementation factors, such as enablers, barriers, benefits, limitations, requirements, and customer perspectives on this facility, affected the applicability. Accordingly, certain factors such as high initial costs, supplier and maintenance constraints, carparking limitations, queue control, and accessibility need to be addressed. The study concludes that by considering these implementation variables, drive-thru banking can yield positive outcomes for both customers and bankers. The study recommends that banks in Sri Lanka explore the potential of drive-thru banking facilities and adopt them as a means of improving their services and meeting customer needs in a changing landscape.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"120 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":"129139032","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}
