Structural Features:
This major expansion to the Piedmont Atlanta Hospital campus houses critical and acute care patient beds, laboratories, and surgery centers.The signature curved geometry of the building was achieved using post-tensioned concrete framing.Tower columns could not continue through the large open ground floor lobby, resulting in the need for a system of massive 10-foot deep post-tensioned transfer girders above.Special measures were undertaken to accommodate the tie-in to multiple adjacent buildings.The sloping site and variable subgrade conditions resulted in significant earth retention challenges and also the need for multiple foundation types.
