Parking structures are a necessity on many sites. Building construction includes mild and post-tension cast-in-place concrete, precast concrete, and in some instances concrete cast onto steel structures. Structural design for these structures is not only for support but also to be able to resist different climate changes over the life of the structure. Because of this, the structural consultant on any project must have an understanding of material attributes to make sure the right materials are being used. Providing options to owners and designers related to differences between structural framing materials and long term benefits along with long term maintenance planning is key to a successful project. Pierce Engineers has experience in this building type in both new design and restoration capabilities.
