Abstract
which involves ensuring its functionality, safety, efficiency, and overall performance by overseeing the operation, maintenance, and enhancement. In maintenance period, conventional Manual method of measurement, which works without the use of automated or computerized systems, of existing buildings is a common method used currently, these manual method approaches are subjected to human errors, since it is done through human manual collaboration which can lead to measurement inaccuracies. These inaccuracies could cause distinctness with existing condition when performing facility maintenance, repairs, or upgrades. Moreover, this method takes a lot of time and effort. When working in large and complicated facilities in particular, it can be a laborious and tiresome process to manually measure, sketch, and annotate the drawings. In this study the way of using technology aid instruments like 3D scanning usage is investigated. Moreover, it studied the perceived difference of the measurement methodologies between these conventional and 3D scanning tools. the data collection and data analysis are done by taking scanned data from existing buildings taken from Addis Ababa residential buildings. The focus group discussion is also taken to reach the challenges of implementing the 3D scanning devices in Ethiopia. It is seen using 3D scanning tools would decrease a time and an effort with more accurate results and give more detailed information with in the same consumed time than traditional measurement system. Then, after comparing two methods, this study figured out what has been the challenges for the vast applicability of this 3D scanning tools in construction sector. It gives some emphasis on which the barriers making applicability of 3D scanning tools on construction firms of Ethiopia. Some are awareness of construction sector which is a limited exposure to these technologies in academic institutions reduced awareness among professionals. And also, the budget issues that is the high cost of advanced 3D scanning tools that are workable for institutions has been a barrier for applicability of 3D scanning tools. Which means a developing country like Ethiopia could have a struggle since budget shortages. After analysing these challenges, this study develops the suitable approach for applicability of this 3D scanning tools in Ethiopia. And finally, the study sets some conclusions and future directions to improve the applicability of these tools in vast.
