|Abstract: ||This thesis work is undertaken to identify the existing project delivery methods in
Oromia region, to evaluate alternative delivery methods and to assess opportunity for
their applicability to the local situations. This is to provide a useful supplement to the
existing methods so that all stakeholders in the construction industry will benefit.
Accordingly, four project delivery methods based on their relevance to the local situation
in Oromia region of Ethiopia have been evaluated; their merits, demerits, and
requirements identified. These methods are: the design-bid-build (DBB), the construction
management (CM), the design-build (DB), and the design-build-operate-transfer (BOT)
The criteria used for selecting (or evaluating) the appropriate method(s) among the
alternative delivery methods were: project time certainty, controlling project cost,
ensuring project quality, and reduction of owner’s administrative burden. These are
sometimes called project objectives. These evaluation criteria (project objectives) have
been decided based on the literature survey and test interviews made at the early phase of
the thesis work.
So as to draw reliable inference, data was collected from four clusters of stakeholders in
the construction industry, namely; public owners, contractors, consultants, and reputed
professionals. The research design was based on exploratory survey, desk study, and
descriptive approaches. Besides, the research instruments used were questionnaires,
interviews, discussions and document reviews. The participants include eight public
owners, seventeen contractors, twenty consultants, and another twenty reputed
professionals. The respondents were selected using random sampling, except public
owners for which purposive sampling was used.

As one of the core responsibilities of the thesis work, assessment of the prioritization of
these project objectives by the concerned bodies has been conducted. Accordingly, it is
revealed that public owners in Ethiopia’s Oromia region wish to ensure project time
certainty in the first place. Their second critical requirement is to attain project cost
certainty. Thirdly, they want to reduce the administrative burden to them. Finally they
indicate that they want to attain a quality project.
This study, as one of its findings, reveals that the current construction projects delivery
method in Oromia region is the traditional Design-Bid-Build (DBB) method. It is also
noted the innovative project delivery methods have never been used.
The DBB method has been short of meeting the above mentioned project requirements
set by the public owners in the study area. Hence, there is a positive attitude towards the
application of the innovative project delivery methods with the public offices.
It has been thought that the local construction industry in Ethiopia is a cost-driven
industry. Taking Oromia region as a study area this thesis work, however, shows that
public owners wish the industry to be a time-driven one. This is because public owners
have come to understand that when the project time is controlled, reduced or maintained
the overhead costs and the consultancy fees can be dramatically reduced. They have also
come to understand that if project time is maintained or reduced, the cost overrun due to
price escalation and inflation can be minimized. Hence, the cost is issue is regarded as a
second priority in selecting among different project delivery methods.
It has been argued that the local contractors lack financial, managerial, and sometimes
technical capabilities to run construction projects under innovative delivery methods.
Based on the assessment of the local construction industry, however, the innovative
methods DB, CM-at-Risk, and CM-at-Fee can be effectively applied in the study area.
This could be accomplished by partnering between consultants and/or contractors and
proper contractor and/or consultant selection.

Partnering maximizes the effectiveness of each of the partner’s resources, and proper
contractor/consultant selection avoids selection of a contractor/consultant that is not fit
for the job to be undertaken.
The traditional DBB method can also be employed in situations when the public owner
wants to involve in several aspects of the project and when time is not a constraint.
It can, however, be argued that the transition from the traditional method to the
innovative methods needs time and involvement of everyone in the construction industry.
And, this paradigm shift ought to be advocated through short trainings, tailor-made short
courses, workshops, research and construction magazines, and any other relevant means.|
