The Lower Sproul Redevelopment revitalized an outdated and unsafe space at a campus gateway area. The project upgraded the plaza; replaced Eshleman Hall with a larger building for student groups; upgraded and provided two major additions to the MLK Jr. Student Union, a 1958 concrete building; upgraded the Chavez Student Center; and retrofitted Anthony Hall, a historic building. Our solutions included developing a noise and vibration mitigation program for the demolition phase, developing details for working with complicated geometries and existing building tie-ins with new structures, and providing performance-based design to accurately minimize the need for retrofitting the MLK Union and for increasing confidence in Eshleman’s seismic performance.
