Risk Assessment of Utilizing the Sosrobahu Device as an Infrastructure Construction Technique

Abstract

Risk is a multi-facet concept. A risk is an uncertain event or condition that, if it occurs, has a positive or negative effect on one or more project objectives such as scope, schedule, cost and quality. As one of the most dangerous industries, risk is said to be common in construction. As the industry strives to remain competitive using variety of innovations, in one way or another, can be connected and be affiliated to more risks due to unfamiliarity or newness of approaches and methods. One of the innovations that are currently being used in infrastructure construction is the Indonesian technology, Sosrobahu, a hydraulic non-friction rotating device that is used to rotate a 450 ton pier head. This is to minimize traffic disturbance while constructing in major economy roads. This technology is used in Metro Manila Skyway Stage 3 that will run from Buendia in Makati City to Balintawak in Quezon City, connecting the South Luzon Expressway and the North Luzon Expressway. This study assessed the risks associated in utilizing the Sosrobahu technology based on the Risk Management Plan of D. M. Consunji, Inc. through survey questionnaires distributed to technical and managerial staff involved in the project. An action plan was proposed for improvement of the existing Risk Management Plan and for project implementation.
