Penerapan BIM 4D dalam perencanaan penjadwalan pada pekerjaan struktur jembatan

Abstract

Currently, many project scheduling plans are still done conventionally, often resulting in errors due to a lack of precision. The development of the construction industry has prompted construction practitioners to adopt a technology system known as Building Information Modeling (BIM). This system is a 3D representation of a construction project that includes various essential information in the planning, design, implementation, control, and maintenance stages. To support the concept of BIM in the scheduling of bridge structure work, supporting software called Vico Office is needed. This research aims to determine the 4D BIM output in the form of scheduling planning for bridge structure. It begins by preparing a digital (3D) model using Tekla Structure. Next, the model is integrated into Vico Office for the scheduling process (4D). The concept of 4D refers to project scheduling based on the 3D model. To obtain the scheduling plan, work breakdown and activity duration estimation are performed using Ms. Excel software. These calculations are done considering the work volume obtained from Vico Office. The relationship between the interdependencies of the planned schedule and the 3D model of the bridge structure is already directly integrated. This research applies the BIM concept to obtain scheduling planning. From the scheduling plan results, differences between the two methods are evident. The conventional method shows a total duration of 270 days, while with the use of BIM, the obtained duration is 284 days.
