Valuable lessons and best practices learned from construction projects often fail to get transferred to future generations due to the lack of a formalized process. This perpetual problem gives rise to the need of imparting fresh training to new inductees once the aging workforce retires or in the event of turnover in an organization. This paper aims to facilitate the process of disseminating knowledge gained in the transportation area by developing a lessons learned database named Communicate Lessons, Exchange Advice, Record (CLEAR) under the auspices of the North Carolina Department of Transportation (NCDOT). A Six Sigma approach to Identify, Define, Develop, Optimize, and Verify (IDDOV) was used to develop the CLEAR database. The IDDOV model in Design for Six Sigma (DFSS) is a five-step process in designing efficient and robust new systems. The first phase involved conducting interviews with end-users as well as reviewing existing data within NCDOT data repositories such as claims and supplemental agreements data to better understand challenges and issues in need of resolution. With this information as basis, an outline for web-based database was created from which feedback was solicited. After taking into consideration all preferences from these end-users, the web-based database was fine-tuned to reflect all comments and suggestions gathered by the research team. This database is currently being populated from ongoing pilot projects. In the final stage of this project, the CLEAR database will be launched throughout the state on all ongoing projects. These five project phases reflect the principles of the IDDOV method of Six Sigma which provides the foundation for developing this database. Findings from this study will help NCDOT to institutionalize knowledge and improve project cost variations and schedule predictability. The success metrics include anticipated reduction in number of claims, claim amounts and increased coordination among staff within NCDOT.

This study seeks to determine the drivers of remanufacturing from the professional's view. The methodology used for this study is the quantitative methodology, a mean item score and a normality test to determine their views and finally used the Mann-Whitney test to determine the views of the professionals. Findings from this research method revealed that there was no significant difference in the way; professionals viewed the drivers of remanufacturing. Further discussed was the implication of the findings, which revealed that the major driver of remanufacturing in Nigeria is the creation of job opportunities, which is vital as Nigeria is presently grappling with a high unemployment rate. Finally, it was concluded with the role remanufacturing will aid with the high unemployment in Nigeria.

The workforce in the 21st century is ageing. There is increasingly larger proportion of workforce 50 years of age or older. This ageing situation is prevalent in the Hong Kong construction industry as about 41% of total registered construction workers in Hong Kong are 50-year-old or above as at 31 Aug 2018, and the failure of the industry to attract younger workers. These situations have collectively led to serious manpower shortage. Most construction workers are experiencing physically demanding works on a daily basis. Workers are also subjected to constant psychosocial pressures including the need to face stressful environmental conditions, long and sometimes irregular work hours, unpredictable workplaces and conditions, and dis-continual employment. In addition, the organisational and institutional arrangements in Hong Kong construction industry are less supportive in providing favourable working environment for older workers. Despite these misgivings, we know very little of the conditions older construction workers experience in Hong Kong construction industry. There is therefore a need to investigate such issues and propose possible intervention to improve the working conditions of our senior workers. With these objectives, in this paper, we first report the findings of a small scale survey on the care of older workers in Hong Kong construction industry, and second propose potential intervention by combining the findings of the survey and our industry observations of the practices implemented by progressive contracting companies in Hong Kong. In developing the intervention scheme, we draw from the approach of the emerging field of integrated health and safety protection and promotion. The scheme focuses on the relationships and causal pathways of the conditions of works to workers’ health and safety outcomes by taking into consideration the organisation and workforce characteristics. It is argued that the framework can potentially mitigate the risks associated with ageing workforce.

Supply Chain Management (SCM) in construction industry is a developing field of study. This paper analyses the results of a questionnaire survey on supply chain management in top US construction industries. A survey was sent out via online tool to more than 100 contracting companies in the US, mapping the relationship between contractors and suppliers, the tools and methods employed in executing the supply chain practices. The survey results indicated that SCM in the construction industry is still in its developing state. They also indicated that the construction industry has been relatively slow in adopting SCM as a tactic due to its complexity and uniqueness. The study recommends several solutions to overcome the above mentioned problems and improve the efficiency of the SCM in the construction industry.

Since robotics become more widespread in the construction industry, more construction phases and work steps must be covered with one robot system. Current robot systems are used almost exclusively in precast construction. At the construction site, so far only prototypes are in use, and only individual parts of the building shell construction and assembly can be covered. This paper examines to what extent fastenings are necessary to increase the operating range of robots and which boundary conditions exist or need to be addressed. Automated construction, and more precisely installation of fastenings, has so far been partially implemented, which has shown increased productivity as well as installation quality, thus load-bearing safety. This knowledge must now be extended to robots. The present work is based on an overview of current research and development and on the current research on a cable robot for brickwork construction at the university Duisburg-Essen. It further demonstrates that fastenings pose an important further application, especially in order to explore the extended phases towards the brickwork or contour crafting. It can be assumed that robots will become increasingly important in the construction industry. Reasons include high quality, safety, speed and economic aspects . The Authors. Published by Budapest University of Technology and Economics & Diamond Congress Ltd. Peer-review under responsibility of the scientific committee of the Creative Construction Conference 2019.
