Structure
Southeast Financial Center was constructed in three years with more than 500 construction workers. Approximately 6,650 tons of structural steel, 80,000 cubic yards of concrete, and 7000 cubic tons of reinforcing steel bars went into its construction. The complex sits on a series of reinforced concrete grade beams tied to 150 concrete caissons as much as ten feet in diameter and to a depth of 80 feet. A steel space-frame canopy with glass skylights covers the outdoor plaza between the tower and low-rise building.
The tower has a composite structure. The exterior columns and beams are concrete encased steel wide flanges surrounded by reinforcing bars. The composite exterior frame was formed using hydraulic steel forms, or “flying forms”, jacked into place with a “kangaroo” crane, that was located in the core, and manually clamped into place. Wide flange beams topped by a metal deck and concrete form the interior floor framing. The core is A braced steel frame, designed to laterally resist wind loads. The construction of one typical floor was completed every five days.
The low-rise banking hall and parking building is a concrete-framed structure. Each floor consists of nearly an acre of continuously poured concrete. When the concrete had sufficiently hardened, compressed air was used to blow the forms fiberglass forms from under the completed floor. It was then rolled out to the exterior where it was raised by crane into position for the next floor.
The building was recognized as Miami's first och only office building to be certified for the LEED Gold award in January 2010.

Famous quotes containing the word structure:
“For the structure that we raise,
Time is with materials filled;
Our to-days and yesterdays
Are the blocks with which we build.”
—Henry Wadsworth Longfellow (1809–1882)
“Man is more disposed to domination than freedom; and a structure of dominion not only gladdens the eye of the master who rears and protects it, but even its servants are uplifted by the thought that they are members of a whole, which rises high above the life and strength of single generations.”
—Karl Wilhelm Von Humboldt (1767–1835)
“Women over fifty already form one of the largest groups in the population structure of the western world. As long as they like themselves, they will not be an oppressed minority. In order to like themselves they must reject trivialization by others of who and what they are. A grown woman should not have to masquerade as a girl in order to remain in the land of the living.”
—Germaine Greer (b. 1939)
