The Building Industry Association of Southern California (BIASC) Junior Builder Program
Through the support and interaction of industry leaders and valuable sponsors, a series of one-to-three-day builders camps have effectively taught students about honoring the history and future of Southern California housing, while learning about principles associated with design, building, energy and so much more.
Most notably and in conjunction with the BIASC’s recent centennial year, members of Junior Builder played an integral role in conceptualizing an award-winning float in the 2023 Rose Parade®.
The 2025 Junior Builder camp calendar will soon be revealed. In the interim, if interested in supporting the builder program through hosting a camp, sponsorship or in-kind contributions, please contact Cristina Walters at cwalters@biasc.org.
