Precast concrete helps mixed use projects become success stories. Mixed use projects require integration of multiple use spaces, which often have conflicting design requirements such as a parking facility (unconditioned space) with a residential facility (quiet space), or with retail. High performance precast concrete envelope and structural systems are used for all types of mixed use projects and provide the aesthetic and structural versatility needed to make them successful. From creating open floor plates for retail and office space, to the aesthetic versatility to make a parking structure blend in with the surrounding environment, to providing passive fire protection. Precast concrete is a high performance material that integrates easily with other systems and inherently provides the versatility, efficiency, and resiliency needed to meet the multi-hazard requirements and long-term demands of high performance structures.
