Chaffey High School GWS Auditorium Modernization


Architect DLR Group
Completion Date June, 2019
Client Chaffey Joint Union High School District
Location Ontario, CA


The modernization to the Gardiner W. Spring Auditorium at Chaffey High School includes multiple improvements to the historic structure. These include a historical restoration and rehabilitation of the exterior, theatrical and acoustical upgrades, new catwalk and steel stairway, addition of two new elevators, accessibility upgrades, lobby restroom expansion, and finish improvements throughout the interior/exterior. During the design phase, Tilden-Coil’s Building Information Modeling (BIM) team completed a 3D laser scan of the entire auditorium, which was provided to the architect for design, and used by our team for coordination. The resulting point cloud included 210 scan locations, 4 days of onsite scanning, and only 30 days to produce an accurate and usable model.
