Investigative study of project procurement methods and project performance indicators in Saudi Arabia

There exist two basic categories of a construction building procurement methods; those that combine project design with construction under one contract termed design-build (DB) and those that separate the design and construction functions into more than one contract or design-bid-build (DBB). This research compares the performance of DB and DBB in the context of the Saudi Arabian construction industry as an example of international construction practices, by statistically quantifying the effects that project procurement methods had on three objective and 10 subjective performance indicators. The notion that DB outperforms DBB is supported by this research.
