IMPLEMENTATION OF BUILDING INFORMATION MODELING (BIM) ON THE USHULUDIN BUILDING CONSTRUCTION PROJECT CAMPUS 2 UIN ANTASARI BANJARBARU
Abstract
In a construction project calculating the volume of work is important. The volume of work affects the estimated cost of the project. Errors in calculating the volume of work are very detrimental to the contractor because it can bring in excess material or material that is less of course very influential on construction costs. Along with advances in technology, the calculation of work volume and project cost estimates can be carried out with the application of Building Information Modeling (BIM) to make it faster and more efficient. This study will discuss the comparison of cost estimates using BIM with manual calculations on the structural and architectural sections of the Ushuludin Building Campus 2 UIN Antasari Banjarbaru.
The structural part of the building is in the form of foundations, beams, columns, plates, and steel and architectural structures in the form of masonry walls. The modeling is carried out using the Tekla Structures software with a South-East Asia environment that refers to the plan drawing. The output generated from the Tekla Structures software is in the form of volume and cost estimates which can be exported directly to Microsoft Excel software, and Microsoft Excel software is used for manual calculations.
From the results of the analysis of cost estimates, it is found that the difference between BIM-based calculations and manual calculations is a difference of 0.36%. With this use of Building Information Modeling (BIM) can be applied because it has a slight difference with manual calculations and processing time is faster.
