BIM Modeling for Memorial Hospital

Case Study Description:

Tesla Outsourcing Services LLC completed a Scan to BIM conversion for Memorial Hospital in the USA. The massive healthcare project covered an overall building area of 306,230 sq. ft. across 14 floors and a roof. The team utilized Revit software with Imperial units of measurement to deliver a Level of Development 350 architectural, structural, and MEP model.

Despite the short turnaround time, the dedicated team managed to complete this hospital project in close to 4 weeks. Key details of the project execution include:

Delivered an integrated LOD 350 model including interiors, facade, and sheets.
Modeled interior and exterior elements, large hospital and lab equipment, ceilings, and building vertical cores.
Maintained rigorous tolerance standards throughout the entire model.
Achieved a level of accuracy between the point cloud and Revit model of plus or minus 15mm.
Ensured a level of accuracy 1 inch from the scan, modeling walls and floors with undulations up to 1 inch as orthogonal or straight.

Revit

Autodesk Revit is a Building Information Modeling (BIM) software platform used by architects, engineers, contractors, and AEC teams to design, document, coordinate, and deliver building projects. Unlike traditional CAD software, Revit connects 3D building elements with plans, sections, elevations, schedules, quantities, and project data in one coordinated model. Its key features include parametric modeling, multidisciplinary collaboration, construction documentation, worksharing, visualization, and model-based scheduling.

Why this tool/tech was selected

The main reason for selecting Revit software for this large scale healthcare facility was to accurately convert complex point cloud data into a precise Level of Development 350 model. Tesla Outsourcing Services LLC needed a powerful tool capable of handling a massive 306,230 sq. ft. building across 14 floors and a roof. Utilizing this specific software allowed the team to integrate architectural, structural, and MEP disciplines smoothly. The tool provided the necessary capabilities to model everything from intricate interior elements and large hospital lab equipment to building vertical cores and facades. Revit was essential for maintaining strict tolerance standards, ensuring a level of accuracy between the point cloud and the final model of plus or minus 15mm. It also enabled the team to efficiently manage phase wise input delivery and ongoing design changes within a short turnaround time.

Challenges the Client Faced before

The client faced challenges with a short turnaround time for a massive hospital project.
The workflow was complicated by phase wise input delivery from the client.
The project required managing ongoing design changes while maintaining strict accuracy.

The previous method used

Traditional manual survey and 2D drafting methods lacked high accuracy point cloud data, making it difficult to capture wall and floor undulations and manage ongoing design changes across a massive 14 floor hospital.

Time / Money saved & the Business Impact.

Using Scan to BIM technology and Revit software provided a significant business impact by allowing the successful delivery of a massive hospital project within a tight schedule. Tesla Outsourcing Services LLC managed to complete the entire Level of Development 350 model, including interiors, facade, and sheets, in close to just 4 weeks. This rapid execution ensured that ongoing design changes and phase wise inputs did not derail the overall project timeline. By maintaining strict tolerance standards and a plus or minus 15mm level of accuracy between the point cloud and the Revit model, the team minimized potential on site errors. Modeling undulations up to 1 inch as straight orthogonal elements provided the client with clean, usable data for facility management. This accurate digital asset ultimately supports efficient long term healthcare operations.
