Precast concrete is the premier building system for parking structures. 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.
Precast is Versatile – Precast provides an incredible array of aesthetics options, whether your parking structure needs to blend in with the surrounding environment or stand out from the crowd. Precast systems also allow for a more open parking deck compared to cast-in-place structures and doesn’t require intermediate columns within the parking area. This improves visibility and security of users.
Precast is Efficient – Precast concrete arrives at the site ready for installation and does not require protection from rain, sun, snow, wind, or extreme temperatures. This saves time and money and reduces the potential for change orders due to winter conditions.
Precast concrete is one of the fastest building systems available, and is manufactured offsite minimizing project site disturbance, while maximizing quality. It is typically erected with a crane and a relatively small crew, which allows for construction within a small footprint and minimizes disruption to the surrounding area.
Precast is Resilient – Precast concrete inherently provides a high degree of quality and durability including better freeze-thaw durability, scaling, and cracking resistance. The high-quality concrete used, and joint system allow for predictable and controlled stress relief that can be addressed with simple maintenance. Whereas cast-in place structures have random, unpredictable, and typically more severe maintenance issues that can result in replacement of the structure. Precast also provides inherent fire resistance and does not require additional fireproofing.
