The Clark Construction Group Inc. recently topped out at the $136-million Southwest Quadrangle Project at Georgetown University.

Totaling more than 860,000 sq. ft. (79,897 sq m), the project consists of five components: three new residence halls (post-tension concrete frame with steel roof structures), a dining facility (structural steel frame), underground parking garage (post-tension concrete frame), a fuel cell bus maintenance facility (post-tension concrete frame) and Jesuit community residence (post-tension concrete frame with steel roof).

With a 3.5-acre (1.4 ha) footprint, the structure holds 50,000 cu. yds. (38,228 cu m) of concrete and 8.5 million lbs. (3.8 million kg) of reinforcing steel. Clark Concrete Superintendent Chuck Watts said, “ Our schedule required many weeks of concrete placement well in excess of 1,000 cu. yds. per week. We met this challenge, casting more than 2,000 yds. in some weeks. We had single daily pours in excess of 1,000 yds. of concrete on the plaza level.”

Designed as three connected buildings, the 314,000-sq.-ft. (29,302 sq m) residence halls will provide 780 additional beds for second-year students. Facilities include kitchens, classrooms, recreation and multipurpose rooms, laundry facilities, study space, as well as chaplain and faculty residence apartments.

Replacing an existing facility, the new 81,170-sq.-ft. (7,541 sq m) dining hall will serve 1,200 students daily. Blending elements of traditional and modern design, the building occupies a pie-shaped footprint with an arching facade to the southwest.

A four-level, 400,000-sq.-ft. (37,161 sq m) underground parking garage will replace a surface lot and accommodate 780 vehicles. A bus maintenance facility will occupy the lowest level of the garage, housing the university’s fuel cell buses — alternative fuel vehicles. Georgetown’s Jesuit community will relocate to the new building that will include public spaces, private quarters and a chapel. Designed in the same traditional style, this four-story, 64,000-sq.-ft. (5,946 sq m) structure complements the new residence hall.
