Task

GPRS captured accurate digital representations for six uniquely structured parking garages at Emory St. Joseph’s Hospital in Atlanta and integrated data into a wayfinding app to improve patient and visitor navigation across the healthcare campus.

PROBLEM

The hospital campus featured multiple parking structures with inconsistent layouts, some aboveground, some underground, and some interconnected across levels.
Patients and visitors frequently experienced difficulty navigating from their vehicles to their medical offices, resulting in frustration, delays, and operational strain on staff.
The total space 3D scanned was 1,681,500 SF and included the following parking garages within the scope of work.
- Green Parking Garage - 6 Levels - 510,000 SF
- Blue Parking Garage - 2 Levels - 160,500 SF
- Purple Parking Garage - 5 Levels - 222,500 SF
- Gold Parking Garage - 3 Levels - 271,000 SF
- North Employee Garage - 6 Levels - 285,000 SF
- South Employee Garage - 5 levels - 232,500 SF

Solution

Before beginning reality capture, the team conducted walkthroughs of each parking deck with the client to confirm the scope and develop scanning strategies tailored to the vast and complex layouts, ensuring no disruption to hospital operations.
In under a week, a three-person GPRS team used the Matterport Pro 3 and Leica RTC360 laser scanners to capture every parking level, space, stairway, and hospital access point.
Accurate reality capture data was used to create individual 3D BIM models for each parking garage and a unified campus model, which served as the foundation for generating 2D plans and immersive virtual tours.
Deliverables were integrated into a mobile wayfinding app with AR capabilities and indoor positioning to guide users through the hospital campus with ease.

Benefits

Reality capture provides the precise spatial data needed to power wayfinding apps, saving parking locations and enabling real-time AR navigation that helps users confidently navigate complex indoor and outdoor environments.
The 3D BIM model forms the foundation for accurate routing, orientation, and destination mapping.
Reality capture supports augmented reality (AR) overlays by aligning digital cues, like directional arrows or points of interest, with physical features in real-world spaces.
Accurate wayfinding reduced reliance on staff for directions, improving hospital operational efficiency.
As-built CAD and BIM documentation of the complex parking structures can be used to support future planning and maintenance.
