The execution of construction projects extends beyond a mere focus on final aesthetics; operational safety and functional mapping remain paramount priorities. Throughout the field implementation phase, various technical challenges must be anticipated and addressed, including material selection, the integration of design with structural integrity, and cost efficiency.

In practice, the transition from drafting to construction often encounters loopholes or miscommunications among stakeholders and civil engineering disciplines. Construction projects executed in haste or lacking interdisciplinary integration lead to prolonged timelines—due to repetitive on-site errors—and inflated costs resulting from inaccurate calculations.

These issues pose significant risks to the long-term sustainability of a structure, particularly in commercial high-rise buildings. As we are aware, commercial high-rises such as hotels are designed with rigorous safety and comfort standards. Consequently, structural elements, architecture, MEP (Mechanical, Electrical, and Plumbing) systems, and other components must be seamlessly integrated.

Addressing these challenges, a Civil Engineering student from Dian Nusantara University (UNDIRA) conducted a study on a commercial tourism sector project in Jakarta: the Marriott Hotel Gelora Jakarta.

To facilitate the study, the student implemented Building Information Modeling (BIM) technology. BIM is regarded as an effective solution, as it provides a visual 3D representation of physical building concepts, simulates potential impacts of technical issues, and offers precise solutions through 3D layouts, thereby enhancing analytical accuracy.

The implementation of BIM aligns with the Regulation of the Minister of Public Works and Housing (PUPR) No. 9 of 2021 regarding Guidelines for Sustainable Construction, which states: "3D models may be utilized for clash detection, energy analysis, material efficiency, and other sustainability analyses."

Furthermore, the analysis utilized BIM software, specifically Autodesk Revit and Autodesk Navisworks, employing the Clash Detection method. This approach automates the mapping of design element conflicts, such as overlaps between piping routes, basement walls, and beam placements.

The Marriott Hotel Jakarta is a 33-story structure featuring four basement levels extending 17 meters below surface elevation. Utilizing data sets obtained from the project consultant—including cost estimation summaries—the researcher inputted MEP models and data into Autodesk Revit before processing them in Autodesk Navisworks. The "Clash Detective" feature was then utilized for advanced analysis.

A Level of Development (LOD) 300 analysis was implemented to ensure high-detail mapping with high-quality graphics, incorporating construction details, properties, and specific information such as accurate dimensions.

The results revealed 544 clash points within the building's integrity. These findings were documented in tabular format with detection imagery as a reference for building management. Additionally, the study found that through further optimization, the application of BIM in wall construction could yield cost savings of Rp 82,191,346.13.

The research output by this UNDIRA Civil Engineering student underscores the significance of BIM and Clash Detection as vital instruments for ensuring efficiency and structural integrity in high-rise projects. The potential for cost reduction and the identification of superior material alternatives provide valuable insights for management to optimize future building structures.
