    A Study of Alternative Wall Making Materials Selection Using Ahp Method
    (Addis Ababa University, 2022-06-01) Behailu Workneh Tolu; Denamo Addissie (PhD)
    Material selection is a complex and delicate task determined by the vast number of building material options. Likewise, multiple factors are often considered by the architect or building designer when evaluating the various categories of building materials. As a result, these sets of factors or variables often present tradeoffs that further complicate the decision-making process. To ease the material-selection process, this study examines the relevant factors or variables needed to develop a systematic and efficient material-selection system. Through the analysis of frequency data and results of the study, it has identified the potential factors that will impact designers’ decisions in their choice of wall making alternative building materials, during the design-decision making process. The application of the criteria for the quantitative evaluation and selection of the best alternative building material, using the analytic hierarchy process model, are discussed. The developed decision support system assist designers to assess their consequences in terms of whether or not a material option is likely to be best chosen over the existing conditions. The study also investigates the existing situations in the application of alternative wall making building materials. It assesses the current materials which are being used as a wall making alternative building materials, the extent of usage and barriers to use these materials.

    Exploring Suitability of 3d Scanning Tools to Enhance Facility Management Practices in Ethiopia: The Case of As-Built Modelling Using Ios 3d Scanning Tools
    (Addis Ababa University, 2025-06-01) Selamab Simeon Sumoro; Denamo Addissie (PhD)
    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.

    Innovative Tendering Practice: E - Tendering Applicability for the Procurement of Ethiopian Federal Road Construction Projects
    (Addis Ababa University, 2021-08-01) Hilina Belachew Demisse; Denamo Addissie (PhD)
    Construction procurement is considered to be one of the most critical stages throughout the lifecycle of construction projects. However, bidding practice which is one of the steps in procurement is identified as one of the major shortcomings of the Ethiopian construction industry. The fact that the current Ethiopian construction tendering practice is paper-based has several drawbacks like human errors in document production, poor audit trail, access problems, security concerns, insufficient copies, and time-consuming being the major ones. This paper analyses the current practice of paper-based tendering in road construction projects along with its challenges & how it can be improved via e- tendering implementation. To answer these questions, the perception & experience of tendering professionals involved in the road construction projects was assessed via a questionnaire & interview survey. Few e-tendering practitioners were also interviewed about their experience while implementing the system. Accordingly, the result showed that e-tendering was perceived to be advantageous and would improve the time, cost, communication, documentation, tender evaluation, resource consumption, and transparency of the tendering process. However, the result also revealed many factors related to management, organization, environment, & technology that may hinder the implementation of the system. Thus, due to the potential benefits of e-tendering highlighted in this paper, it requires more attention from the government & the procuring entities for its greater expansion & adoption to ultimately contribute to the growth of the country‟s economy. Accordingly, findings from the literature review, survey, and document review were finally incorporated in the conceptual framework developed for e-tendering implementation in the study area. The framework was validated using a focus group discussion & a semi- structured interview with tendering professionals engaged in the study area and amendments were made accordingly. Its clarity, comprehensiveness, relevance, simplicity, & future applicability was also assured via the questionnaires developed.

    The Level of Women’s Involvement in Project Management Positions in the Ethiopian Construction Industry
    (Addis Ababa University, 2025-04-01) Serawit Getachew; Denamo Addissie (PhD)
    This study explores the extent of women’s involvement in project management positions within the Ethiopian construction industry, with a particular focus on Addis Ababa. Despite increasing awareness of gender equity, gender diversity improves innovation and decision-making in construction, women remain significantly underrepresented in leadership roles across the sector. Most existing studies in Ethiopia focus on general construction roles and there is a lack of practical frameworks to support women’s advancement in PM roles. Therefore, the study aims to assess the level of female representation, identify the challenges hindering their participation, and propose effective interventions to enhance gender inclusion in project management roles. The conceptual and empirical literature review with relevant international and Ethiopian experiences was conducted to examine key challenges, representation gaps, and strategies for career advancement. A mixed-method research approach was adopted, combining quantitative data from 394 survey respondents drawn from a population of 25,000 licensed construction professionals, with qualitative insights from interviews and a focus group discussion involving female project managers. The research employed descriptive statistical analysis for quantitative data using SPSS, and thematic analysis for qualitative data to ensure comprehensive interpretation. Findings reveal that women constitute a small minority in project management roles less than 10% and face multiple structural, institutional, and socio-cultural barriers. The study identifies 6 major challenges, including physical demands, Unequal Job opportunities between men and women, gender bias, lack of mentorship and training programs, work-life imbalance, and Unsociable work hours and harsh working condition. Moreover, only a few companies reported having active goals or policies to promote female leadership. The research concludes that there is an urgent need for sector-wide strategic interventions, including gender-sensitive recruitment policies, mentorship programs, flexible work arrangements, and targeted leadership training. These measures are essential not only for enhancing women’s participation in project management but also for improving overall organizational effectiveness and equity in the Ethiopian construction sector.

    The Practice of Building Demolition In Addis Ababa City: Current Practice Assessment and Regulatory Framework Development
    (Addis Ababa University, 2022-06-01) Tirufat Mekuria; Denamo Addissie (PhD)
    The Addis Ababa city Administration has been demolishing old buildings and clearing up slum areas for urban renewal purpose for quite some time now. This is being carried out either as part of a government development plan or due to strong interest of foreign investors to participate in the housing and hospitality sector. In addition, increased value of land invited local private property owners to upgrade existing structures in to more income generating spaces aiming at maximizing benefits. However, the practice is not coping up with the technological advancements in the area; rather it is highly dependent on the experience and skill of individuals involved. The fact that Ethiopia doesn’t have a code of practice for building demolition has paved the way for the practice to be performed in non-structured manner. This research started aiming at achieving three objectives; the first being examining the current practice of building demolition in Addis Ababa city. This was done by using selected cases to detect the loop holes through direct observation and interviewing representatives of parties involved in a building demolition project. Furthermore, an in-depth document analysis was done on existing local protocols; ranging from policies to codes and regulations, that can serve as a starting point to develop the framework. As a result, the gaps were analyzed in five major categories related to stakeholders management, planning and methodologies, safety, environment and waste management, productivity and performance recording. The second objective goes on with examining the international trend of the sector through intensive review of literatures so as to derive key performance indicators to evaluate the local practice against later on. For this, it was necessary to benchmark certain countries with best practice, such as Kenya, India, Hong Kong and the Netherlands. Afterwards, standard factors extracted from the study were categorized under generic sections after critical adaptations are made. The third and final objective of this research was to develop a guiding regulatory framework aiming to serve as a milestone point for the regulatory authority. The developed framework describes the main actors of the building demolition ecosystem and states the major responsibility of each entity for the success of the cycle. Finally, it concludes by summarizing the findings of the research in such a way that the practice lacks proper emphasis from the regulatory body in terms of standardizing work items like contracts and safety protocol strictly to follow while performing the act. In addition, qualification of professional is another area which needs big work in order to rescue the system being reliant on personal skill. As far as the recommendation points are concerned, the study suggests for the upper regulatory body to draft a standard code of practice so as to set the minimum requirement of professionals and the other stakeholders. In addition, it was also recommended that regulatory body to have a distinct organ dedicated to keeping the performance record of the sector in order to make future plans and structure demolition acts in more coordinated manner. At last, studies related to waste management and recycling, pattern against city expansion and application of prefabricated elements vs demolition are suggested for further research.
