Abstract: Currently, the construction industry is one of the biggest industries in Ethiopia contributing 10% to the Gross Domestic Product (GDP). It needs to be emphasized that road construction in Ethiopia is the means through which development are achieved. The economic growth of the country depends on availability and utilization of physical infrastructures. Road construction and utilization in Ethiopia are the means through which development strategies are achieved. The development of road construction projects can be enhanced through well-established Asset Management system that will improve tactical and operational decisions by applying the required knowledge to gain wisdom for provision of strategic infrastructures. However, most of the road construction in Ethiopia encounters problems due to lack of proper Asset Management practices. In this respect, this study’s objective was to investigate Roads Asset Management practices in Ethiopia the case of AACRA. In order to find answers to the research questions and to achieve the objectives of the study, quantitative and qualitative ways of research adapted. Interviews and questionnaires analyzed quantitatively whereas the desk study analyzed qualitatively explanatorily to assess alternatives, diagnose a situation, and discover new ideas. Accordingly, interpretation and discussion were made on the basis of results. The findings of the study revealed that there is lack of: Asset management system components implementation rated as low with a result of 54.5%, 63.6%, 64%, 82% and 73% respectively except condition assessment rated as medium with a result 45.5%, technologies like individual management system implementation in AACRA is in the planning phase as the response of the (7) professional in aggregate revealed, Integration of those management systems also is not there yet. Decision making levels are not explicitly defined in AACRA except programming and budgeting level rated as 54.5%. 91% of respondents revealed that there is lack of professional associations, conferences, short courses and 73% of the respondents disclosed that there is lack of organized asset management department. Some of the specific recommendations forwarded are decision making levels should be explicitly defined, applying different individual management systems and integration of those management systems is necessary and etc. Finally framework were developed for effective and efficient Road Asset Management.

Abstract: The Kathmandu valley was formed by draining the lake through Bagmati River of the Chobar gorge in the ancient time. The bedrock inside the surface of Kathmandu valley consists of clay sediment i.e Kalimati (It means the black soil in Nepali) clay which is also called the dense impenetrable black mud. This type of soil is very fertile. The people of the valley utilized the geographic structure and the natural resources with skill to enhance civilization, which is shown from the traditional water supply or the hiti (Dhunge Dhara in Nepali) system. It is also called the water spout or rainspout. This study was conducted during the period from January to June 2020. Published literature such as paper, manuals, reports, and database were collected from different sources and went on thoroughly. The study found that the population of Kathmandu and Lalitpur is increasing rapidly but the source of drinking water is decreasing gradually. In the past, Dhunge Dhara was feeding the communities for drinking water as there are all together 237 Dhunge Dhara in Kathmandu and Lalitpur area. In the Kathmandu Valley, the source of water spouts decline is due to the development of various engineering infrastructures such as roads, buildings, towers, and so on. Similarly, rapid growth of urbanization took place near the source of water spouts. As a result, there could not be the chance of ground water recharge. The water from the rainfall flows directly through the waste pipe to the river. In the past, there were irrigation canals called Rajkulo (Canal made by the King in the Kathmandu Valley), these canals effectively recharged the ground water. As the valley is converted into the city of concrete, it causes stoppage of ground water recharge near the hiti. Consequently, there is no water in the water spouts i.e. in Dhunge Dhara. The study would like to suggest that the traditional Dhunge Dhara in the valley must be preserved through the initiation of the local, provincial and central government.

Abstract: New environmental challenges and research opportunities arise on the use of solid wastes as well as their basic properties. In fact, recycling of these wastes and their by-products is attracting increasing interest worldwide because of the high environmental impact in the cement, concrete and other industries. Two types (type1: Fa100 and type 2: Ba100) of sludge ashes from the sludge waste center of Camberene (Senegal) were combined with different proportions of lime to assess their potential us

Abstract: In the area of project construction industry, risk management has become an indispensable index of concern which needs to be focused on in order to ensure effective and successful execution of projects in the construction industry. This paper focuses on risk management within projects construction field and also to find out the opinions and ideas on the significance of the construction projects risks, and also to explore the risk analysis, risk response techniques and strategies as well as risk management processes and practices in construction industry. The questionnaire prepared for the survey was distributed both via e-mail and by sending questionnaire link onto a WhatsApp platform group of the respondents and 85 member respondents results were analyzed in the form of bar charts, column chart and radar chart. The survey results revealed that majority of the total respondents are in the capacity or position as Project Managers and also have over 15 years working experience, and as well attained Master’s degree qualification. It was also revealed that risk events are usually responsible for the poor delivery and quality of work, accompanied with delays and other associated losses in project construction and also risks that are associated with high probability and high impact are required to undergo further analysis, including quantification and thorough risk management. The most frequently used risk response technique according to the respondents is through the issuance of performance bonds, warranties and guarantees and also the most frequently used risk analysis practice is the Project Documented knowledge and Review Analysis. Risk management in project construction is therefore a constant learning process to constantly improve upon practices in order to adapt and increase the process efficiency of dealing with risk in construction projects as well as its successful execution.
