Engineers with Performance Engineering were retained to provide structural design services for the new Platte Valley State Bank. The 47,000 square foot banking facility is designed to accommodate the ever changing and expanding financial services of its client, the structure consists of three above ground levels and a full basement. The building system features a variety of innovative structural designs. The roof is a steel joist system. The second and third floors consist of a composite concrete deck system and the main floor level is a hollow core precast concrete system all supported by a steel frame. To allow for the numerous windows throughout the building, lateral stability is provided by rigid steel frames concealed in the exterior walls and in the middle of the facility. Another interesting structural feature is the three-story stair system that is the focal point of the west entry. Although it appears to be hanging in mid-air, it is actually supported by a single strut at each landing and at each floor level.
