Abstract
The project delivery method is the process by which a project is comprehensively designed,
procured and constructed. Design-Build is a method which an owner deliver both design and
construction responsibility for a single firm. An important issue associated with Design-Build
delivery method is that time savings, cost certainty and owner is free from both design and
construction risks. Also it maximizes the contractor‘s ability to use innovative designs, materials,
and scheduling, managing and construction techniques. While the single point of contact can be
easier, the checks and balances that exist between the architect and contractor are missing, which
can create conflict between the owner and Design-Build firms. It can be difficult to assess
whether the best price has been achieved.
This research investigates the challenges of implementing Design-Build delivering process on
Ethiopian Road Authority (ERA) projects. During conducting these research available
documents relevant to the research were reviewed journals and articles, books, internet sources
and archival document such as progress reports, completion reports, and contract documents. Indepth
review of literature, desk study and case study are conducted and then an interview
questions for each contracting parties are designed. The interviewees were asked face to face
with interviewer. Then the data were analyzed for cross-checking the validity and conformity of
the information obtained through the overall research work and literature review. This is
followed by thorough discussions in order to draw a conclusion and to forward recommendations
based on the findings of the study.
The research concludes that ERA‘s implementation of DB projects delivery system requires
improvements on criteria or requirements to select delivery method, preparation before tendering
and on administration during construction. ERA should focus heavily on the qualifications of the
design-builder and its key team members rather than price or best-value procurement; and
rewards design-build teams that have a demonstrated history of successfully collaborating on
design-build projects.
