Risk impact on cost and time from the factors of contractor’s managerial and operational

Abstract

Aceh Province over the last 20 years has experienced different events that can be divided into 3 (three) phases. 1st Phase is the phase of the conflict (2000-2004), 2nd Phase is the post-earthquake and tsunami rehabilitation and reconstruction phase of Aceh (2005-2009), and 3rd Phase is the post-rehabilitation and reconstruction phase (2010-present). Events that occurred during the last 20 years are certainly likely to provide risks to community activities in the province of Aceh. One of the activities affected by the event is the construction project work. The implementation of construction works affected by events in Aceh Province over the last 20 years is highly vulnerable to risks that impact on achieving project objectives such as cost and time. This study analyzes the impact of the contractor and operational managerial risk factors on the cost and timing of construction. Data were obtained from questionnaires distributed to 15 large qualification companies in Aceh Province. Testing data is done by using the validity test and reliability test. Data that has been valid and reliable then analyzed by using Severity Index (SI). The variables of a managerial risk factor with SI to the highest cost in 1st Phase are F5 (incompetent Engineer), 2nd Phase is F3 (lack of contractor experience), and 3rd Phase is F5 (incompetent Engineer). From the operational risk factor, the highest cost SI in each phase is the G3 variable (electrical disorder). The managerial risk factors with the highest time SI in 1st Phase are F6 (lack of top management support), 2nd Phase is F5 (incompetent engineer), and in 3rd Phase is F3 (lack of contractor experience ). From the operational risk factor, the highest time SI at each phase is G3 (electrical disorder).
