They face a lack of basic needs such as clean air, water, sanitation and healthy foods. Rapid urbanization leads to increased demand for condominiums and focused on slum-free cities to get maximum utilization of high potential prime lands. As a solution, shipping container housing (SCH) concept has been successfully practiced in many countries in all over the world to promote low cost housing (LCH) for resettlement projects. Therefore, this research intends to explore the use of SCH concept as a LCH for permanent resettlement projects in urban areas of Sri Lanka. A comprehensive literature synthesis emphasizes the suitability of SCH concept as a LCH solution and it proved that approximately 60% of construction cost can be saved by using this SCH concept over the traditional construction methods. Selected case study for this research was “low income permanent resettlement programme in Colombo city”. Finally, the study revealed that use of SCH concept as a LCH solution for resettlement projects in Colombo will not be a feasible solution due to the specific retarding factors from the low income groups, specific characteristics of shipping container boxes and climatic conditions of Sri Lanka. Moreover, this study was very useful for the governing authorities to identify the leading alter factors between the theoretical concept and practical implementation of low income permanent resettlement projects in Sri Lanka.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129945447","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}

Mechanical and electrical (M&E) services accounts for a significant proportion of building projects. Apart from the cost effect, a reduction in carbon footprint can be achieved through M&E services as the capital allowances system and tax relief provides the mechanism to promote sustainability through innovation in green technologies and energy efficiency. However, the training of quantity surveyors in M&E is often ad hoc making it difficult to realise the maximum potential in carbon reduction. The aim of the study is to enhance the M&E trainings to the Quantity Surveyors (QSs) in order to better contribute to carbon reduction and sustainability of buildings. The objectives were formulated as to examine the opportunities for carbon reduction through capital allowances and tax relief and the training implications for Quantity Surveyors (QSs). Using an explorative survey and semi-structured interviews, the study found significant gaps in knowledge of the quantity surveyors as limited attention is given to training in M&E services. There is need for a review of training programmes to ensure that the QS professionals can maximise the potential in reducing carbon emission through the provision of appropriate cost advice on M&E services that will benefit from capital allowances and tax relief. Other countries can learn from the experience of the UK Government policy, statutory and regulatory framework that underpins the development of capital allowances and tax relief to change behaviour by providing tax and fiscal incentives that will have a positive impact on carbon reduction to mitigate climate change.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122678554","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}

If the payments get delayed, the resulting financial burden will go down the supply chain to reach even the subcontractors and suppliers, thereby further complicating the situation. Since payment delays are common in Sri Lankan construction projects as well, especially when the projects are funded by the government, the proper management of payment delays is important. This research was, therefore, conducted to identify how the consequences of payment delays in government funded projects in Sri Lanka could be properly managed. A literature review and sixteen semi-structured expert interviews were carried out to collect the required data, which were subsequently analysed using manual content analysis. The study identified 77 causes of payment delays in government funded projects and 51 strategies that can minimise them. The study recommends the enactment of the Construction Industry Payment Act, enforcement of regulations that make it mandatory to have a sum of money deposited in an independent escrow account, getting the employers to work only within the stipulated budgets, and getting them to provide payment bonds.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129087910","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}

Strength in terms of sustainability, particularly in the PDR of developing countries, is undoubtedly still not at an adequate level. One of the main challenges that affecting for the success of the PDR project performance is that not managing community cultural continuity properly while affording development opportunities in PDR projects which end up with cultural incompatible solutions, which are unsustainable in the long run. The success of PDR project performance is based on the success of their main 4 components: site, layout, construction and policies. The study identifies how those components of PDR projects are affected by the community culture with the lessons learned by past PDR project experiences all around the world. Further, the cultural factors which affect for each feature of PDR has been identified through the findings. Besides the thorough literature findings, the study has presented with proposed methodological aspects in order to continue the study in future.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121977402","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}

Nevertheless, the current water management practices of irrigation are not achieving the benefits of sustainable use of water. The failure in achieving the expected performance of irrigation infrastructures urges the need for Sustainable Water Management (SWM). Therefore, the purpose of this research is to investigate the issues in existing Irrigation Water Management (IWM) practices towards SWM of irrigation systems in Sri Lanka. The research aim was approached through a qualitative survey strategy. Expert interviews were conducted as the data collection technique. Twelve experts were selected through a purposive sampling strategy, who had experience in water management and technical development in irrigation systems. The collected data were analysed using the manual content analysis method. Findings of the research revealed that though numerous techniques are being practiced in IWM, there is a failure in water management in the current context. It was identified, water losses throughout the system, improper system operation and poor maintenance of structures, inefficient practices of irrigation, dis-integration of system components and lack of government intervention as major issues to achieve sustainable use of water in the case of irrigation. The identification and assessment of issues provide a range of their impacts to reveal the constraints in achieving SWM of irrigation.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"193 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122357967","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}

Recently, views on building maintenance had undergone fundamental changes and are currently thought of as a crucial function in any organisation. Regrettably, around one-third of the allocated maintenance costs are wasted due to the ineffectiveness of maintenance planning. As a remedy to this loss, many organisations are currently shifting towards the incorporation of maintenance strategies such as corrective maintenance, preventive maintenance, and predictive maintenance. However, the implementation of these strategies itself will not solve the problem. Significant planning should be undergone in order to obtain the maximum benefit of executing these strategies. Introducing a tool to support planning and decision-making regarding maintenance strategy implementation will hence simplify this process. Therefore, the aim of this paper is to review existing literature on maintenance strategies and develop a fuzzy logic model to find the best combination of such maintenance strategies for concrete structures. Hence this paper portrays a conceptual model that can be adopted to benchmark maintenance strategies for concrete structures, by adapting the existing models which are commonly developed for maintenance of machinery and equipment.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115694198","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}
