| dc.description.abstract | In the conventional approach of construction projects, the design and construction processes are not implemented in integrated approach. The design work often begins with the client’s need identification then after discussion and agreement the architect and engineers prepare the design with the available resources and constraints. After the completion of the architectural and the engineering designs the procurement and construction will continue respectively. In the process of the design and construction processes are not integrated. This lack of integration between the two processes is the cause of many problems like cost overrun, delay, less quality, incompatible with the available technology and so on, in general lack of constructability of a project. Project delivery methods have the major impact on the integration of the design and construction process. According to literatures DB is a better project delivery method with regard to integration of design and construction phases and constructability issues over DBB. The main objective of this study is to review and assess the theory and actual practice of the project delivery methods with respect to the integration of design and construction and the effect of constructability in public building projects in Addis Ababa. In order to realize the objectives, case study of three selected public building projects in Addis Ababa is reviewed. In contrary to the literatures, the results of the case study indicated that, in public projects, the DB project delivery method is not practiced in proper manner like; the right type of condition of contract is not implemented , the design and construction processes are not integrated and others. Accordingly in the actual case of public buildings in Addis Ababa DB have many problems, even higher than DBB projects with weak quality control, too much variation, time overrun, and dispute between contractual parties. In addition the concept of constructability is not practiced in the studied projects of either in the DBB or DB public building projects.
