ACI - Qualcomm AY Building Tour

Written by Alyssa Burley.

On October 14, 2014, Project Cornerstone representatives Crystal Howard and Alyssa Burley attended ACI San Diego's Architectural Concrete presentation and tour of the Qualcomm AY Building.  The event was held at the Qualcomm Pacific Center Campus in SanDiego.

The presentation and tour was designed to highlight the innovative ways concrete can be used in building design.  The Qualcomm AY building uses concrete as both an architectural and building material.

Crystal and Alyssa met some of the people who worked on the project and spoke with others about the Project Cornerstone's educational programs and the golf tournament fundraiser.
