Schuster Performing Arts Center
TWC’s portion of the project involved constructing an orchestra pit and a concrete stage wall. The pit includes interacting-radius, cantilevered structrual slabs; a large concrete culvert; multiple radius foundation walls, and footings. The concrete stage wall is 130 feet tall and 120 feet wide, and only 18 inches thick. The wall has numerous offsets and pilasters, and had to be built within 3/8 of an inch plumb from top to bottom
Construction took place on a small, congested downtown site in the middle of winter. The total project encompassed more than 23 pours and 4,000 yards of concrete. A special layout team dealt with the project’s painstaking details. A special gang system was designed for the 130-foot high walls. Crews worked 10-hour days, six days a week, even during the holiday season, and since a crane was needed for every pour, they had to quickly become acclimated to heights. More than 200 change orders were given to TWC throughout the project.
Productivity on the stagehouse walls resulted in seven lifts of 15 to 18 feet each, with four lifts being turned around in nearly three weeks.
TWC Concrete Services Building
The heavily detailed tilt-up requred some thinking out-of-the-box to bring the structure to life. From the very beginning, TWC wanted to make a statement. After various designs and extensive input, TWC chose to build the unique design that is now their headquarters.
To offset the ordinary flat surface tilt-up, TWC chose to add reveals, rubbed finishes and fins with structural tubing that would provide shadow lines. These fins were tied to the main structure with 1/4″ rods through the panel joints eliminating the repetitive look of most tilt-ups.
Also, the radius curtain wall at the main lobby was topped off with a 10″ high ribbed wall that was poured on site, on the ground and lifted into place. It was braced not only for the wind load but also had to be temporarily braced from the ground up until the semi-circle was welded together to function as one unit.
The most challenging, but yet striking, feature of the building is the lobby. After deciding to scrap the structural steel stair and mezzanine framing, TWC chose to form a cast-in-place waffle system for the mezzanine with a striking radius staircase that the fine craftsmen at TWC took great pride in forming. This concrete spiral staircase was a unique challenge in formwork and design.
