Abstract

The BBPJN XI/PJN I Kalimantan Flats construction project only applies manual scheduling in the form of an S curve. This building consists of 9 floors with reinforced concrete material. Currently, there is BIM technology that can minimize problems caused by manual scheduling in controlling time. So in this study, a study will be conducted on the application of 4D BIM-based project scheduling using the Tekla Structures 2020 software from manual project scheduling.The building modeling refers to the plan drawings, including piling and reinforced concrete structural work in the Tekla Structures 2020 software. Scheduling is made using the Task Manager extension found in Tekla referring to the RAB, S curve, and interviews with the project party. The modeling results are then inputted into the Task Manager to provide 4D visualization with the help of the Object Representation extension combined with the Project Status Visualization extension.Based on the results of monitoring project progress (tracking) inputted into the Task Manager, it is known that lower structural work was completed two weeks earlier. Upper structural work started from the ground floor starting one week earlier, and all structural work was completed 16 days earlier than scheduled plan. The duration of the work generated by Tekla Structures 2020 is 126 calendar days. The work starts from October 19, 2020, to February 21, 2021. So, with several extensions owned by Tekla, it can be said that the use of Tekla Structures 2020 software in the implementation of 4D BIM can be relied on for monitoring and minimizing errors in scheduling.

Abstract

This study focuses on the use of Building Information Modeling (BIM) which begins with creating a 3D digital model (virtual building) which serves as a means for planning, designing, implementing development, and maintaining the building and its infrastructure for all parties involved in the project. Unlike other studies that use concrete structures, this study refers to the Bauntung Banjarbaru Market building with a steel structure. BIM software program is specific and correct. Specific is within the use of BIM information is taken and adapted to real conditions within the area. Correct is a constructible model, that is, the model that is created is the same as the model that was constructed. Besides, when there is a change in the model, the resulting cost estimate can change automatically.Modeling of building structures includes modeling of reinforced concrete structures and steel structures. The modeling is done using a software called Tekla Structures with a South-East Asia environment that refers to the plan drawing. After the modeling is complete, the work unit price is inputted into the software. The output of this modeling is direct cost estimation for structural work. For manual cost estimation using cost budget plan that has been obtained from the contractor in the form of a Microsoft Excel file.From the results of the analysis of the two cost estimates, the resulting comparison of the cost difference is quite scanty. The difference between manual cost estimation and BIM based cost estimation is 0.26%. So, it can be concluded that the use of BIM based cost estimation can be used because it produces cost estimates that are faster than using manual calculations made by contractors.The use of BIM can reduce costs and inaccuracies in the calculation of estimates in projects because it can be done more thoroughly. Keywords: BIM-based cost estimation, Tekla Structures, building structures

Abstract

Follow-on Project of the Tapin Regency Regional Secretariat Office Building located on Jalan Datu Suban, Tapin Utara, Kalimantan Selatan is a reinforced concrete building project that only applies manual scheduling which is present in the form of S Curve, PUPR Ministerial Regulation Number 9 of 2021 states that projects ought to be base on BIM. Therefore, this research will discuss implementing 4D BIM (scheduling) using Tekla on the Follow-on Project for the Construction of the Tapin Regency Regional Secretariat Office using Tekla to determine the use of BIM on scheduling obtained from contractors.This research method starts from studying the software and the object to be modeled, collecting the data such as as-build, S Curve, RAB. Data processing start from 3D modeling using Tekla Structures 2020, scheduling with Tekla Task Manager, and then 4D modeling with object representation.Scheduling made from the Budget Plan (RAB), S Curve, and interviews of related parties are then inputted into the Tekla Task Manager with dependencies which are applied into the bar chart. The 4D model is created using the visual logic with the integration of the 3D model created by scheduling, the development planning stages can be displayed according to the reviewed date. It was concluded that Tekla Structures could be applied in scheduling the follow-up project for the construction of the Tapin Regency Regional Secretariat Office Building.Keyword : scheduling, Tekla Structures, Tekla Task Manager, Model 4D, Follow-on Project.
