Traditional design methods often fall short in meeting expectations related to speed, sustainability, and coordination in such interdisciplinary projects. Building Information Modeling (BIM) has emerged as a promising solution, addressing modern healthcare facility needs by supporting development planning, remote monitoring, and enhanced functionality. This study aims to showcase the role of BIM in the planning, analysis, and design of a sustainable hospital building.The project adopts a multidisciplinary workflow using several software tools, including 2D layout planning, 3D modeling, and structural analysis and design (IS: 12433 Part 2, 2001). For sustainability assessments, Autodesk Insight and One Click LCA are used (Hui et al., 2024; Li Zhao et al., 2024). Modern hospital design integrates construction innovations like waffle slabs, daylighting, and glass facades to optimize energy use while enhancing occupant comfort (Indrajit Chowdhury & Jitendra P. Singh, 2010; Alaa et al., 2011; Sandeep et al., 2014). All major design elements are regularly reviewed for compliance with IS codes, the Energy Conservation Building Code (ECBC 2017), and other standards. This work highlights the advantages of integrating BIM with sustainability tools, leading to improved project outcomes, reduced environmental impact, and a replicable model for future healthcare infrastructure. 2. Methodology The project adopted a collaborative approach integrating BIM tools, structural analysis software, and sustainability assessment platforms to design a constructive, analytical, and sustainable G+4 hospital building. Initial spatial planning and zoning were drafted using AutoCAD, ensuring clear circulation and regulatory compliance. The 2D layout was then imported into Autodesk Revit to develop a detailed 3D model representing both architectural and structural components. Custom Revit families were created for key elements like doors, windows, columns, and waffle slabs, all aligned with Indian Standards (IS) for accuracy and compliance. The 3D structural model was transferred to Tekla Structural Designer by a team member for analysis and optimization. Structural components were analyzed under dead, live, and distributed loads with a focus on grid slab performance, ensuring strength, serviceability, and cost efficiency. Sustainability evaluations included a carbon emission analysis using One Click LCA, assessing both embodied and operational carbon across the building's lifecycle. An energy performance analysis using Autodesk Insight provided the Energy Use Intensity (EUI). A solar performance analysis evaluated the contribution of rooftop PV panels to energy demand, and a daylight analysis confirmed compliance with ECBC 2017 standards, ensuring adequate natural lighting in occupied zones (Francisco et al., 2020). This integrated methodology ensured that the building met functional, structural, and environmental goals through the use of advanced BIM, simulation, and analysis tools.

The ground floor serves as the main access level with a clear circulation layout and a centrally located staircase for vertical movement. In line with NBC 2016 accessibility standards, a multifunctional ramp is included to accommodate persons with disabilities, addressing space constraints (NBC 2016). Room layouts feature defined entry and exit points, with corridor and staircase widths maintained at a minimum of 1.2 meters for smooth movement and emergency access. Toilets and wet areas are vertically stacked for efficient plumbing. While NBC 2016 recommends additional staircases for larger occupancies, site limitations allow only one. The front façade uses glazing to enhance daylight access and indoor comfort. Upper floors replicate this layout for structural uniformity, improving cost efficiency and ease of maintenance. The second floor includes an operation theatre and recovery ward; the third and fourth floors accommodate general wards, ICUs, private rooms, and service areas. A fire exit ramp with a 1:12 slope is added due to the building's height exceeding 15 meters. Corridors are adequately spaced to support circulation and
