Since this effort has to be made on the expense of time and cost, which can be used otherwise to add more value to the project, it is vital to decide an effective mechanism to mitigate subcontract disputes. Considering the need for addressing this fact, this paper aims to investigate causes of subcontract disputes and effective prevention measures. Mixed approach was followed in order to achieve the aim of the study. Thus, a preliminary survey was conducted to validate literature findings and a questionnaire survey was carried out with contractor and subcontractor representatives to identify causes of subcontract disputes and prevention measures. The findings of the preliminary survey were analysed using content analysis technique and data captured through questionnaire survey was evaluated using relative important index and weighted mean. Incompleteness of the contract was identified as the primary reason of disputes in subcontracts. Further, financial issues, risks and uncertainties, collaborative conflicts, opportunistic behaviours of contracting parties and wrong practices also have a significant impact on occurrence of disputes. Proper contract management and proper site management which includes scheduling and effective project management practices were identified as the most effective prevention measures. The contract administrators should identify the things they should necessarily address in the contract and project managers in dispute prevention regards should consider time and cost constraints to prioritize effective prevention measures.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116894270","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 was also found out that the construction activities create negative impacts on the environment. Reducing the negative environmental impact of the construction industry is one of the major challenges in the 21 century. However, regardless of the significance of this problem, limited efforts to deal with the negative effects have been largely fragmented and disjointed. Green Supply Chain Management is considered as one of the main efforts, which aim to integrate environmental parameters within the supply chain management. It reduces carbon emissions and improves environmental performances of organizations. The trend towards developing Green Supply Chain is now increasing among various industries. In the recent past, enterprises have started Green Supply Chain Management for the purpose of securing competitive advantages over other initiative due to the increase of international conventions related to the recent climate change, the global environmental protection regulations, the stakeholders and investors’ need for environmental suitability and the consumer’s choice for environmentally friendly products. Therefore, this paper aims to critically review the secondary data on Supply Chain Management, Sustainable Supply Chain Management, and Green Supply Chain Management in the construction industry. Finally, the paper presents a conceptual framework integrating concepts for Green Supply Chain Management practices to the construction sector.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121573535","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 performance of the most construction projects is tracked utilizing planned cost vs. actual cost measures only. Earned Value Management (EVM) technique came into existence as an effective performance measurement and a feedback tool for managing projects by emphasizing more on the Earned Value (EV) of projects. Regardless of the immense benefits of EVM, there are significant deficiencies in the process of implementation of the EVM technique in Sri Lanka. Therefore, this study aims to develop a conceptual framework for effective implementation of EVM in the Sri Lankan construction industry with specific reference to the Project Management Institute’s (PMI’s) standard for EVM. A qualitative research approach was used to accomplish the aim of the study. The empirical findings were analyzed using the manual content analysis technique to determine the degree of implementation of the PMI’s standard for EVM in Sri Lanka. The deficiency of professionals and inadequate conceptual knowledge were identified as the most critical barriers associated with the implementation process of the EVM technique. Allocating a separate team to execute the EVM technique, arranging short courses on EVM, developing a standard master format for project performance measurement are the measures that this study recommends promoting the adoption of the EVM technique in the Sri Lankan construction industry.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131239439","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}

Innovative and smart technologies are emerging to provide inevitable benefits because of their capacity to enable digitisation, automation, and integration of Solid Waste Management (SWM) processes. Nevertheless, the application of such technologies in Construction and Demolition Waste Management (CDWM) has not gained the appropriate attention. This study aims to draw insights into the current and potential use of smart technologies in CDWM. A literature review-based approach surveyed both academic and applied publications to analyse the current and potential use of smart technologies in both SWM and CDWM. Altogether, 75 peer-reviewed articles and technical white papers were analysed. It was found that the usage of smart technologies is much advanced in SWM and the adoption is still at the prototype stage in CDWM. The results emphasise that the integration of smart technologies into multiple processes of CDWM would overcome many issues related to waste minimisation and management including waste estimation, waste reporting, and data management and waste diversion. The framework developed in this study contributes to the understanding of the potential role of each category of technologies in improving the waste management processes in the C&D sector. This review is useful to waste management practitioners, regulatory bodies and the government to understand the benefits of emerging technologies and to the development of effective strategies and future training","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116362005","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}

Therefore, it is vital to use resources efficiently and effectively. Considering this requirement of any construction project, creating value for money is becoming important. It contributes to the economic, social and environmental aspects of a country. The concept of value is based on the relationship between satisfying needs, expectations and the resources required to achieve them. Value Management (VM) is recognised as a suitable approach to ensure value for money in construction projects. Although, VM concept is significantly used in developed countries, its applications do not seem to be well established in the construction industry in most of the developing countries including Sri Lanka. This is mainly due to lack of understanding of VM concept. Hence, this study aims to investigate how to bridge the theory-practice gap in VM in Sri Lankan construction industry, through seven case studies. Case study data collection was based on interviews, document review and observations and analysed using content analysis. The research findings revealed that these projects employed different kinds of VM methodologies derived from standard VM methodologies with the focus of various VM objectives. The study further identified number of reasons for theory-practice gap in VM such as lack of a formal guideline and less knowledge on VM, which dilute successful VM implementation. The experts further proposed train in-house VM facilitators, proper project planning, motivate investors, train Sri Lankan professionals by foreign experts and govern VM knowledge sharing as strategies to bridge the gap in order to deliver best value for client’s money.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130765329","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}
