Located five blocks from the White House, the National Geographic’s Grosvenor Auditorium needed specialized surveying services using the latest 3D laser scanning technologies. The National Geographic Society wanted to create a 3D graphic of its 4,800 SF Grosvenor Auditorium at 1600 M Street, NW, Washington, DC.
VIKA responded to this need. The goal of this project was to create a 3D model that the Client could use to evaluate and test the lighting in the theater. The Client also wanted to have a way to study the corresponding line of sight from each of the 385 seats.
For this project VIKA provided surveying services to scan the interior of this auditorium. VIKA delivered a very detailed 3D model through 3D high-definition laser scanning. The Team captured every detail of the seating arrangement, lighting, stage, ceiling, walls, and floors. The 3D model allowed the Client to create a unique guest experience from each seat.
This undertaking presented three main challenges:
- The auditorium’s ceiling was a very complex structure with members placed very close together.
- The project required a very accurate location of each seat so that the client could evaluate the view from each one.
- There was a large amount of detail that had to be captured in the Point Cloud in order to prepare the model and satisfy the client’s needs.
To create this model, VIKA generated 3D scans constructed from several vantage points to capture the rich amount of detail in the auditorium. The Team scanned the interior space using high-level resolution to capture diagnostic information—lighting grid, seats, floors, walls and ceiling.
The data collected was processed and registered in a 3D Point Cloud. Use of the Point Cloud allows VIKA to prepare very accurate 3D models to establish existing conditions.
Using the 3D data, VIKA produced 2D drawings showing the scans and other relevant auditorium details. VIKA prepared exhibits to present the accurate location of each seat, the detailed floor plan, and a reflective ceiling plan. All these deliverables including exhibits in CAD and sketch-up formats, would allow the Client to use them in detailed designs.
As part of this project, VIKA also provided Color 3D photogrammetry. In addition, the Team produced a detailed engineering report using the photogrammetry images.
Currently the auditorium—named in honor of Gilbert Hovey Grosvenor, father of photojournalism, and the first full-time editor of National Geographic Magazine—offers state-of-the-art projection, customized lighting, and sound capabilities to its clients.
VIKA’s surveying services included:
