Integrasi 2D dan 3D Tekla Structure Gedung Beton Bertulang sebagai Proses Building Information Modelling (BIM)
Abstract
Abstrak
Proyek pembangunan gedung laboratorium RSUD Sumberglagah Mojokerto menggunakan struktur beton bertulang, seluruh elemen struktur dikerjakan secara langsung di lokasi (cast in place). Dalam proses pembangunan ditemukan masalah ketidaksimetrisan kolom struktur. Untuk mengatasi melebarnya masalah tersebut, diterapkan Building Information Modelling dengan melakukan permodelan struktur gedung. Software Tekla Structure memungkinkan pembuatan permodelan tiga dimensi secara detail pada setiap elemen struktur. Tekla Structure dapat melakukan penghitungan kuantitas material secara otomatis (quantity take-off), sehingga kebutuhan volume beton dan besi dapat dihitung secara akurat. Integrasi antara gambar dua dimensi dan tiga dimensi mempermudah pembacaan dan review gambar, sehingga dapat meningkatkan kualitas dan akurasi desain perencanaan maupun saat pelaksanaan. Hasil quantity take-off menunjukkan terdapat selisih volume antara perhitungan konvensional dengan analisa dari Tekla Structure. Penerapan Building Information Modelling menggunakan Tekla Structure diharapkan dapat memberikan solusi efektif dalam menyelesaikan masalah struktur dan meningkatkan efisiensi perencanaan serta pelaksanaan proyek.

Abstract
The construction project of the laboratory building of Sumberglagah Mojokerto Hospital utilized a reinforced concrete structure, all structural elements were cast in place. During the construction process, there was a problem with the asymmetry of the structural columns. To solve the widening problem, Building Information Modeling is applied by modeling the building structure. Software Tekla Structure memungkinkan pembuatan permodelan tiga dimensi secara detail pada setiap elemen struktur. Tekla Structure can automatically calculate the quantity of materials (quantity take-off), so that the volume requirements of concrete and steel can be calculated accurately. The integration of two- dimensional and three-dimensional drawings makes it easier to read and review drawings, thereby improving the quality and accuracy of planning design and execution. The quantity take-off results show that there is a volume difference between conventional calculations and analysis from Tekla Structure. The application of Building Information Modeling using Tekla Structure is expected to provide effective solutions in solving structural problems and improve the efficiency of planning and project implementation.
