Abstract: The design-build construction project is implemented in Taiwan not by a single company but by a make-shift group of several companies. Hence, problems to coordinate the professional construction management and the supervising architectural company often occur for lack of longterm experience to work together.  In this research, the various factors that affect the implementation of designbuild projects currently practiced in Taiwan were analyzed using the analytic network process (ANP). The objective is to study how the twelve key factors in the four layers of “Role Assignment”, “Signing Contract”, of implementing the designbuild project in Taiwan. The results reveal that “Delay in Payment” has the most negative influence with 15.62% weighing factor; “Latent Risk” comes next with 11.14% weighing factor, and “Responsibility of Construction Company for Project Quality” is the third with 10.79% weighing factor.

Key words: design-build； design-build construction company； professional construction , management； analytic network process (ANP)
