Thus, the research aimed at conducting a comparative cost analysis of different drywall technologies in DHR as alternatives for fulfilling the growing demand for DHR; in doing so, this paper contextualised a mixed research design comprehending a twofold empirical study, which includes a preliminary-expert-interview survey and a questionnaire survey. Content analysis and statistical tools assisted the data analysis. Research outcomes revealed that labour cost-effectiveness, material availability, and sufficiency of unskilled labour are the most influential cost parameters. All ten drywall technologies are effective in terms of the initial cost and can further be tested to choose the best technology for a DHR. Novel aspects of this research are (i) evaluating various cost elements of different drywall technologies for DHR in Sri Lanka, and (ii) presenting research outcomes in a scorecard and a tiered list of drywall technologies, which facilitate choosing economically efficient drywall technologies to accelerate DHR. The scorecard is not restricted to DHR but it is widely practicable for other applications in SL.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"63 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":"121911418","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}

Further, the quality of rural roads is a significant factor to be maintained. On the other hand, maintaining quality has both positive and negative impact on social sustainability, which has been identified as one pillar of sustainability. Apart from these facts, there is a lack of research studies regarding the social sustainability and quality of rural roads at the construction stage. Although the term “social” was introduced into sustainability lately, quality is an intangible aspect. Therefore, this research was conducted to address the research gap in managing the effects of the quality of rural road construction on social sustainability. Data for the research was collected through a literature review, semi-structured interviews with conducting among fifteen selected relevant professionals of the project and an industrial document review from the documents maintained by the contractor. The research attempts to show what effects can be identified and the strategies that can be followed to overcome those effects. For that, ten social sustainability factors and fifteen quality aspects of the construction phase has taken. According to the geographical condition of the selected project area, the number of effects related to each social sustainability factor was different. Further, it was found that few quality aspects impact multiple social sustainability factors. The findings of this research prove that both accessibility and safety-related effects have been encountered critically while achieving the selected quality aspects of the rural roads during the construction stage.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"15 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":"125770630","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}

However, country like Sri Lanka is yet to experience its optimum potential application. Thus, this study investigates the application of green roofs in Sri Lanka in terms of current status of its application, role in the green rating systems and implementation barriers to enhance its application in Sri Lanka. Initially, a preliminary survey, followed by semi-structured interviews with green roof construction professionals was conducted where the collected data were analysed using descriptive data analysis techniques. Amongst the identified set of applications, residential and commercial buildings are the most common building types with the extensive and semi-intensive green roof types. Although the most commonly used rating systems of GREENSL® and LEED have various provisions, a very few out of number of buildings surveyed have incorporated green roofs. According to the green roof construction professionals, the application is limited in the Sri Lankan buildings due to fourteen (14) key barriers. Amongst those barriers, higher initial and maintenance costs, poor awareness of the public on the concept and lack of clients’ willingness on the concept are the mostly identified barriers by the interviewees. Hence, the study recommends taking necessary actions to mitigate the barriers in order to enhance the green roof applications on the Sri Lankan buildings to optimise the multiple benefits if offers.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"27 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":"127131200","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 economic crisis was characterised by several economic problems, including currency devaluation, high inflation, and rising debt levels. Building construction materials prices have also increased drastically during the economic downturn period. These increases in the price of building materials were attributed to several economic factors including inflation rate increases, local currency devaluation and changes in government decisions and regulations, to name a few. Hence, the main aim of this research is to assess the impact of economic decisions on building construction material prices in Sri Lanka during the last 10 years. The mixed research approach was followed to achieve the aim of the study. A comprehensive literature review followed by a market survey to find building materials price data and fifteen semi-structured interviews were carried out with construction industry professionals during the empirical investigation. The collected data was analysed through materials price data analysis and code-based content analysis using NVivo. The findings revealed inflation rate, interest rate, and foreign exchange rate as the key macroeconomic factors that influence the price determination of building materials, while other economic factors and decisions also affect the building material prices in Sri Lanka. Further, this study proposed possible strategies and mitigation measures to minimise the impacts. Construction industry stakeholders can use the research findings to implement the appropriate strategies to minimise the building material price escalation impacts.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"38 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":"121550141","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}

However, it is now increasingly believed to be an area of discussion and concern world-wide. Academic dishonesty takes many forms. These include plagiarism, cheating in examinations, contract cheating, etc. The causes of academic dishonesty include lack of awareness particularly in relation to plagiarism, student perceptions of peer behaviour, failure to integrity students into the academic community and financial, time or academic pressures, etc. Honour codes have for long been developed and implemented at colleges and universities in the USA. Honour codes include traditional or modified honour codes. Honour codes underline the core values of an institution and enable students to play a much bigger role to influence peer behaviour and to police academic misconduct. Honour codes promote holistic growth and development of students rather than focussing on the punitive nature of academic integrity policies per se. The work reported in this paper is based on a literature review and concludes that tackling academic dishonesty effectively at colleges and universities require a multi-pronged approach including implementation of the academic integrity policies, the honour code, creative pedagogical practices and a supportive approach to learning and development of students’ skills.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"26 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":"126803941","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}

Numerous studies have found that the construction sector has experienced a rapid and continuous digital transformation to tackle these issues. As a result, to successfully implement Industry 4.0 applications in the Sri Lankan construction industry, it is necessary to identify the status quo of digitalisation in the Sri Lankan construction industry. Therefore, the research aims to analyse the status quo of digitalisation in the Sri Lankan construction industry. The study employs a mixed-method approach consisting of two phases. In phase one, a questionnaire survey was conducted for 50 respondents selected through snowball sampling. The collected data were analysed using SPSS. In phase two, semi-structured interviews were conducted with 11 experts who had knowledge of Industry 4.0 and lean construction, selected through purposive sampling. Data analysis was conducted through code-based content analysis using NVivo 10. The study indicated that the overall level of digitalisation of the construction industry is lower, while BIM (Building Information Modelling), 3D printing, and Drones/Unmanned Aerial Vehicles (UAV) are the most often implemented applications. Research has made significant contributions to knowledge in identifying issues in the current construction industry in Sri Lanka and the level of implementations of Industry 4.0 applications in the construction industry to measure digital disruption in the industry. Accordingly, the research provides a path to investigate the barriers to implementing these industry 4.0 applications and strategies to eliminate those barriers to raise the construction sector's overall digitalization level.","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":"122400226","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}

There has been an increasing trend in the promotion of sustainable construction (SC) in the industry. The implementation of SC practices is a vital step in construction projects to reduce the adverse impacts on the environment economy and society. While numerous challenges affect sustainable construction projects, those challenges continue to obstruct the further implementation of sustainable construction practices. However, the execution of SC projects in Sri Lanka is not up to an acceptable sufficient level due to many challenges. Hence, this research focused on the investigation of the challenges of executing SC practices in Sri Lanka. A quantitative research approach was adopted for the fruitful achievement of desired objectives. A questionnaire survey was designed to collect data and targeted 30 professionals including quantity surveyors, engineers, project managers, architects and other professionals in the industry. The results of the analysis revealed the importance and the existing applicability of SC practices in Sri Lanka. However, the results show that the important SC practices in Sri Lanka do not apply to a sufficient level in the Sri Lankan industry. Lack of government support, increasing energy costs and lack of existing SC principles are the major challenges to the SC in Sri Lanka. Finally, the findings recommended further improvement of SC practices in Sri Lanka with the perspective of legal, educational, technical, and financial efforts.","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":"131992558","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}

In order to address these concerns, effective management throughout their lifecycle is crucial. Sustainable Project Management (SPM) is a managerial concept that sustainability of a project from inception to completion. Although SPM has received less attention compared to other concepts, it assists project managers in achieving sustainability across all three bottom lines. This study examines the SPM methods employed by mechanical, electrical, and plumbing (MEP) contractors in Sri Lanka. MEP sector is selected to narrow down the scope of the study. Subsequently, a qualitative research approach was adopted to collect data with semi-structured interviews involving ten MEP contractors who have experience and exposure in the industry. The sample was selected using snowballing sampling to ensure the diverse representation of MEP contractors of different scales throughout the study. The research findings highlight that the adoption of SPM practices in Sri Lanka is relatively low compared to international standards, primarily due to a lack of awareness among project managers. Furthermore, MEP managers face challenges in exerting control over their environments, emphasizing the need for a change in attitudes. The results of this study will contribute to efforts aimed at reducing the environmental impact of construction activities, promoting social equity, and enhancing long-term economic viability. Moreover, these findings will serve as a catalyst for further research exploring potential improvements in the implementation of SPM practices.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"25 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":"134240025","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 subsequent research initiatives, however, are scattered around several application areas, with different levels of maturity. This would prove troublesome for a potential researcher to identify a suitable research gap and carry out impactful research. Addressing this, the study attempts to identify the evolution of blockchain research in the construction industry and its current and future trends through a systematic literature review. The review identified that blockchain research is gaining popularity in construction sector exponentially and is expected to continue that pace. The developed countries are dominating these application oriented researches while developing economies are lacking behind. Research on adopting blockchain in procurement and design and construction processes has been done substantially while newer topics are evolving since the beginning of this decade, focusing on the sustainability initiatives of the sector and fusing other digital technologies with blockchain. It is believed that while procurement and design related researches iterate their findings, these new topics would define the blockchain researches in the years to come. Also, attention should be paid on holistically evaluating the blockchain solutions considering not only the technological aspect but also the sustainability, resilience and the productivity of the industry, which is yet to be observed in the studies.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"45 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":"133067549","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}
