    (Adddis Ababa University, 2023-06-01) Jarso Gollisa Roba; Wubishet Jekale Mengesha (Phd)
    One of the issues a construction project might encounter is claim. Construction claim is essentially a demand made by one party to another. Claims will arise whenever a party alleges either an event has occurred or a right is denied or an obligation has not been performed that entitle a remedy to be requested. They may be classified by the related parties, rights claimed, legal basis, or characteristics of claims. Whatever the claim, the ultimate goal is to be qualified for an extension of time or/and additional payment. Studies show that public infrastructure projects have major claims and challenges. Accordingly, this paper analyses the current practice of claim handling process in federal road construction projects, challenges faced claim handling processes & the way it can be improved. The perception & experience of claim professionals involved in road construction projects was assessed via questionnaire & interview surveys and case studies were also used. Accordingly, the result showed that claim handling process in federal road projects has mainly four steps, which are identification, notification, substantiation and assessment and evaluation. There are also three main participants in a typical claim handling process involved in federal road projects; employer, contractor, and claims certifier/engineer/employer representative. Additionally, the result also revealed that many challenges faced during handling of claims. Inaccessibility of documents used to identify a claim, delay in notification claims timely were critical challenges of identification and notification process respectively. Incomplete records/report submission, unsatisfactory evidence to convince other party, poorly submission by contractor/lack of details and particulars were the top ranked challenges of substantiation and assessment process correspondingly. Developing good record keeping system, having good knowledge on terms and condition of contract document, take proactive claim management measure are ranked high by the respondents for improving the claim handling process. Furthermore, to support the survey result the research used some selected case studies and conduct in depth investigation and analysis. The finding expected to provide an important study results for client, contractor and consultant as well as professionals within the area of the study by easily identifying the core and sub-problematic areas.

    Availability, Accessibility, and Optimization of Children's Spaces in Mass Housing: A Case Study Of Summit Condominiums in Addis Ababa, Ethiopia
    (Addis Ababa University, 2024-06-01) Jarso Gollisa Roba; Dagnachew Addugna (Phd)
    Children today have significantly less access to outdoor play spaces than previous generations. Moreover, the design of existing spaces often fails to meet the dynamic needs of modern children, resulting in decreased engagement in outdoor activities. This study investigates the availability, accessibility, and usability of children’s play spaces within Summit Condominium, Addis Ababa. It critically examines how the spatial design of mass housing environments influences children’s outdoor play opportunities. As Ethiopia continues implementing mass housing programs to address rapid urbanization, ensuring child-friendly spaces becomes increasingly vital. Employing a mixed-methods approach, the research integrates physical site analysis, spatial analysis using Space Syntax methods, systematic observations, questionnaires, and focus group discussions. These methods assess the physical and visual accessibility of outdoor spaces, community perceptions, and actual utilization patterns of children’s play spaces. Findings reveal that although Summit Condominium includes designated open spaces, most are poorly designed or misused, limiting support for children’s independent play. Physical barriers such as parked vehicles, poor connectivity, and safety concerns further restrict access. Additionally, community perceptions prioritize green areas and parking spaces over play areas, often excluding children from available outdoor spaces. The study concludes that current planning practices in Addis Ababa’s mass housing developments inadequately address children’s spatial needs. It recommends integrating child-centered design principles, enhancing community awareness, and enforcing policies that protect children’s rights to play within urban residential environments. The study emphasizes participatory design approaches, advocating for children’s involvement in designing optimized and inclusive play areas. Ultimately, this research contributes to the broader understanding of child-friendly urban design and offers scalable recommendations for improving play spaces in mass housing developments.
