Abstract

Formwork that is often used in construction projects is multiplex formwork. Multiplex is formwork made of wood and is classified as conventional formwork that is also resistant to moisture. Multiplex is an efficient formwork material because it is easy to produce, economical, and flexible to use, even in constructions with complex designs. The use of efficient and effective construction materials is an important aspect of building design, especially in the context of multi-story building construction. In recent years, the use of multiplex as a construction material for floor and beam formwork has gained greater attention. Multiplex, which is made of bonded layers of wood, has various advantages, such as being lightweight, easy to install, and reusable. The selection of formwork installation methods determines the quality of concrete that can be achieved, because formwork that is too difficult to install or takes too long to reuse will result in suboptimal concrete work. Based on the formwork material shrinkage value on each floor, for example on the first (second) floor with a shrinkage value of 100%-93.45%=6.55% while the shrinkage value on the second floor (third) reaches 100%-88.84%=11.16%, and the effectiveness of repeated formwork use in formwork work is the reuse of formwork on the first floor (first) by 93.45% and on the second floor (second) by 88.84%.

Abstract

The development of Building Information Modeling (BIM) technology has greatly contributed to improving the efficiency of the construction planning and implementation process. This study discusses the application of BIM in the construction project of the Putra Pondok Pesantrean Amanatul Ummah dormitory building in Mojokerto, East Java, using Tekla Structures. The main objectives of this study are to produce a three-dimensional (3D) structural model, create a four-dimensional (4D) implementation schedule, and compile a five-dimensional (5D) cost estimate. This research uses a case study method by processing project shop drawing data, which is then modeled using Tekla Structures. The structural modeling process begins with the foundation, sloof, columns, beams, and floor slabs. The resulting 3D model is then combined with the construction schedule to form a 4D simulation and calculate the cost estimate through 5D modeling. The results of the study show that the modeling of the Foundation, Sloof, Columns, Beams & Floor Slabs (3D) structures has been carried out. From the 4D simulation, the project implementation schedule starts on January 2, 2025, and ends on November 11, 2025. The total calculation of the Cost Estimate (RAB) for the structural work is IDR 3,043,967,282 (three billion forty-three million nine hundred sixty-seven thousand two hundred eighty-two rupiah).
