Abstract

Delays and cost overruns in construction projects in Indonesia often occur due to suboptimal planning and the lack of BIM adoption, which risks reducing the competitiveness of the construction industry. This study implements BIM by reviewing the structural work of the Student Dormitory Project at Sriwijaya University. The research aims to identify BIM 4D visualization (scheduling) using Tekla Structures and BIM 5D (cost estimating) using Cubicost, evaluate work volume and cost estimation using both BIM and conventional methods, and analyze the factors causing cost discrepancies. The research comparison of work volumes between the conventional and BIM methods shows that BIM results in a lower concrete work volume by 21.22 m³ (3.48%), while the conventional method has a lower initial rebar work volume by 0.37%. After recalculating the tie beam, BIM also results in a lower volume with a difference of 2,930.51 kg (3.33%). In cost estimation, BIM proves to be more cost-efficient, with a 3.48% savings for concrete work and savings of 3.51% and 7.84% for rebar work before and after the tie beam recalculations, respectively, amounting to a total cost difference of IDR 234,323,229.13 (11.32%). These discrepancies are influenced by differences in calculation assumptions between the conventional method and Cubicost, human error in data input, and ambiguities in the Detailed Engineering Design (DED) drawings.
