Abstract
The owner contracts with a single business to undertake both the design and construction work in a design-build project method. The DB construction project delivery method seeks to expedite the construction contracting process by consolidating the design and construction responsibilities for a project into a single contract. One of the newest bank headquarters building projects, Abay, is being built using a design-build delivery method. Design-build projects present unique opportunities and challenges. This study aims to investigate the opportunities and difficulties associated with the design-build delivery method for the Abay Bank headquarters project. The study was of the descriptive research kind, and the necessary data was gathered through interviews and questionnaires. Both qualitative and quantitative data collection was used in the study. The population size of this study is twenty-one and census sampling technique was used in this study. Employee of contractor, consultant and client representative are participants of this study. The qualitative analysis was executed First, the data were sorted, topics were searched for, coding was done, a coding system was created, a code scheme was used, and the findings were analyzed and interpreted. The study's findings indicate that the primary obstacles facing the design-build delivery system include issues with coordination and communication, unforeseen delays or cost overruns, concerns with risk distribution, and the client's hasty decision-making. The study's findings also demonstrate the benefits of a design-build delivery system, which include accountability, less administrative work, better risk management, and single-source accountability. The study's conclusions are crucial for the company's next initiatives and close the empirical evidence gap at Abay Bank. According to the study, it is crucial to develop a communication strategy that outlines the responsibilities, roles, and procedures for each stakeholder, including the client, designer, contractor, and subcontractors. It also suggests that there should be continuous communication and a clear definition of risk allocation in the Design-Build contract, as well as who is responsible for delays, unanticipated site conditions, and design errors. The report suggests that more investigation be done into a cost-benefit analysis that contrasts the Design-Build delivery approach with conventional design-bid-build for projects of a similar nature at Abay Bank.
