description: In today's Ethiopian construction climate, there is increasing pressure to improve project<br> performance in terms of completing projects faster, improving quality and reduce the cost<br> of administering their construction programs.<br> Agencies like Addis Ababa City Roads Authority (AACRA) shall have clear contracting<br> strategy which basically comprises of three components; to have appropriate project<br> delivery system (PDS), procurement procedure and payment provision to respond and meet<br> the demands such as best-value performance to assure project quality and enhance<br> performance. In Addis Ababa City, road projects were primarily built through a traditional<br> Design-Bid-Build (DBB) delivery approach in which unit price construction contracts are<br> awarded to the lowest bidder. While the traditional project delivery approach has served<br> the City well, it has also received criticisms stemming from cost and time overruns and<br> quality problems. Contract administration and entire relationship among parties has been<br> ended up with litigious relationships.<br> Innovative and alternative project delivery system for contractor selection process factors<br> which along with price, seek to improve project performance or achieve other specific<br> project goals is particularly important to implement road construction projects for Metro-<br> Politian Cities like Addis Ababa.<br> Therefore, the objective of this paper is to analyze practices and challenges of existing<br> traditional project delivery method and recommend an alternative and innovative project<br> delivery system for Addis Abba City Road Projects.<br> The research paper includes extensive literature review for unique characteristics,<br> advantage and disadvantage of the traditional DBB project delivery method, and other<br> innovative and alternative project delivery methods. Samples from 21 projects which were<br> built in the last 5 years and whose progress is more than 70% are taken for analysis to<br> examine practice and challenges of existing delivery method and recommend alternative<br> PDS.<br> v<br> Accordingly, questionnaire was designed to assess practices and challenges of AACRA<br> based on important parameters distributed for client, contractors and consultant’s staff.<br> Respondents were also requested to choose convenient PDS for particular project nature.<br> In addition, case study was conducted also on six projects which were implemented<br> through DBB delivery method.<br> The finding of the research both from questionnaire and case study revealed that projects<br> implemented by AACRA through traditional project delivery method have serious cost and<br> time overrun and quality problems. The results of analysis have showed that variation<br> orders were issued due design errors and scope changes.<br> Pre- construction management including risk management practice and overall integration<br> with Sub city administration and utility providing agencies is poor in AACRA.<br> There is no clear decision matrix to suggest PDS which best fits of project goals for<br> particular nature. In line with this, the researcher has learnt that contractors and consultant<br> performance management system and clear accountability framework and system is not<br> being practiced to avoid week performing designers, supervisors and contractors during<br> the tender process.<br> The result of this research is helpful for AACRA to establish PDS guideline to manage all<br> possible risks better before project commencement for ease of successful completion of<br> projects.
