Piedmont Atlanta Hospital Marcus Tower

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.
