Factors causing design schedule delays in turnkey projects in Taiwan
an empirical study of power distribution substation projects
Because of its benefits, the turnkey project delivery method has received much global attention; however, turnkey contractors often have difficulty completing projects within the contract schedule. This paper identifies the schedule delay factors in the design turnkey projects in power distribution substation projects in Taiwan through case studies, expert interviews, questionnaire surveys, and statistical data analysis. It reveals that, of 27 delay factors that affect design schedules in power distribution substation projects, the most common delay factors are "public contending or political involvement" and "tedious review processes of government agencies." The paper examines the key terminologies used and reviews several studies relating to general delay factors, delay factors for the nontraditional project delivery method, and delay factors and key success factors for turnkey projects.
