This thesis offers a comprehensive risk assessment methodology that provides a
decision support tool, directed for Turkish construction organizations, which can be
utilized through the bidding decisions for international construction projects. Within
this context the analytic network process technique is implemented to develop a risk
assessment model, which is used to derive the relative priorities of the risk factors
associated with international construction projects. The findings of the risk
assessment model have demonstrated that the most significant sources of risk are
vagueness of contract conditions about risk allocation, client, and immaturity of legal
system in the host country. Factors such as low % of advance payment, geographical
distance, and bribery were found to be relatively insignificant. An international
construction project risk rating software application is then developed. The
application incorporates the derived priorities from the risk assessment model to
calculate a risk rating for a given international construction project. To increase the credibility of the results a risk rating adjustment methodology was
integrated into the application. Its purpose is to count for the potential influencing
factors that may increase the risk level of a given project. The influencing factors
which were considered are the company&rsquo / s experience, contract type, level of the
available project data from the outset, and project delivery system.
The application is also structured to enhance the organizational learning practices. It
improves the process of the organizational memory formation with respect to postproject
risk data by developing a database of risk information of the rated projects for
future references. The reliability of the application was tested with post-projects risk
data and was found to be satisfactory.
