MMI provided structural and civil engineering services for this 26-story, 450-room hotel, meeting room space, and restaurant facility. The building structure consists of post-tensioned concrete floors throughout the tower section and a combination of mildly reinforced two-way floor slabs and concrete on composite metal decking with composite structural steel beams at the lower podium levels. Structural design of the building was performed using ETABS, a finite element analysis and design program, incorporating lateral loads generated by a wind tunnel study. Foundation considerations included seven hundred linear feet of steel sheet piling to protect adjacent city streets and historic buildings, as well as allowing for the installation of more than 4,000 cubic yards of concrete for the foundation and first floor. More than two hundred fifty 20” diameter steel pipe piles were driven approximately 220 feet below grade, with a design load of 290 tons to support the structure. The ground floor and foundations are all cast-in-place conventionally reinforced concrete sections including the pile caps, elevator pits, and grade beams, as are the shear walls and all columns.

The civil scope of work consisted of new sidewalk construction along South Peters Street and Poydras Street, a new pedestrian mall along Fulton Street, and tie-ins to city utilities.
