To enhance campus security across four schools, CGC partnered with Bandera ISD to construct new security vestibules designed to provide controlled entry points and improved visitor management. These secure lobbies are integrated into the existing buildings through selective demolition and reconstruction, with careful planning to maintain daily school operations.

The work involves concrete and masonry modifications, steel framing, and interior finish upgrades including aluminum storefront systems, hollow metal doors and ballistic glazing. Additional scopes included gypsum wall assemblies, acoustical ceilings, flooring, and paint. Mechanical, electrical, and low-voltage trades were coordinated to install lighting, access control, structured cabling, and surveillance systems—delivering a comprehensive solution that prioritizes both student safety and administrative functionality.
