Design and build a 154,662-square-foot facility that would serve as an advanced research and development lab as well as consolidate Vistakon’s different disciplines. Completed in 2002
DESCRIPTION:
This project involved attaching site-cast Tilt-Up concrete panels to a structural steel frame. Tilt-Up was selected because of its ability to meet the tight schedule and cost constraints. Also, Tilt-Up offered the same architectural appeal as the precast design.
INNOVATION:
This building was originally designed as a precast building, but by switching to a steel-framed building with Tilt-Up cladding, the design and construction team was able to expedite the schedule. The structure was planned to allow maximum flexibility since the ratio of lab to office space varied significantly from group to group. The flexible space allows the “double-stack” of laboratories to convert to a combination of lab and open office space where appropriate. Panels had to be set-up, bolted and welded before they could be released by the crane. Further, because of their size and magnitude, the panels were erected on top of each other. A decorative form-liner lines the top portion of the panels around the entire three-story building. White concrete is accented by a blue-tinted glass to give the facility a modern look.
This project was a 2004 Tilt-Up Concrete Association (TCA) Achievement Award Winner in the Manufacturing/Industrial category.
Design and build a four story parking garage capable of parking 543 vehicles that would complement the adjacent 4 story tilt-up office building.
DESCRIPTION:
This project involved design and construction of a four story parking garage constructed using tilt-up concrete bearing walls, precast concrete columns, precast-prestressed floor beams and cast in place supported concrete floor slabs.
INNOVATION:
This parking garage is unique in that all of the concrete members were cast on site. This included the precast beams and columns which are typically plant cast. The exterior walls of the garage were constructed using tilt-up concrete wall panels which combined the columns and spandrels into a
single panel, thereby eliminating steel connections that are normally
required to connect these items. Lateral loads were resisted by large tilt-up shearwall panels that were tied monolithically to large foundations through the use of wet cast concrete joints between the foundation and wall panels. In some cases multiple adjacent panels were connected together to act monolithically, also through the construction of a wet cast concrete joint between the panels. Architectural interest was achieved by recessing some panels behind adjacent walls to create shadow lines and depth to the outside of the building.
Design and construction of an 87,418-square-foot warehouse facility laden with style and flair. Completed in 2002
DESCRIPTION:
The building consists of load-bearing panels that support the precast concrete second floor and roof framing system. Precast double tees and beams are supported on continuous concrete haunches cast monolithically with the panels.
INNOVATION:
This facility is anything but a boxy warehouse and the architectural treatments that were utilized greatly enhance the visual appeal of the building. Tilt-Up was selected for this project because of its ability to provide both a functional workplace and architectural versatility. Special attachments were designed that would not disturb the exterior features of the facility. Panels were arranged in an eye-catching stair-step pattern and balconies extend from the second floor offices. Cast-in-place concrete eyebrows and canopies were cast after the panels were erected and are supported by the panels. Many of the outside faces of the panels are 75 percent covered with reveals and recesses. Further, the visual interest is enhanced by the corner feature panel that includes a 15-foot horizontal cantilever, reveals and eyebrows on each side.
This project was a 2004 Tilt-Up Concrete Association (TCA) Achievement Award Winner in the Distribution/Warehouse category.
Provide structural engineering services for a new 57,500 square-foot, two- story classroom and administration building at Embry-Riddle’s Daytona Beach location.Completed in Summer 2007
DESCRIPTION:
This project included the use of interior structural steel framing along with load bearing exterior masonry walls to support the second floor and roof framing systems. The exterior utilized a combination of brick and Alucobond cladding to match the architectural theme throughout the campus.
INNOVATION:
This building utilized a cantilevered structural steel second floor framing system to allow the second floor to flare out over the first to achieve the desired architectural appearance. In addition, the building includes a two- story open atrium at the main entry with a cantilevered second floor balcony to allow for a voluminous area for various university functions.

Utilize an extremely intricate process to construct this 116,367-square-foot five-story facility. Completed in 2004
DESCRIPTION:
The owner selected Tilt-Up because of its load-bearing capabilities, hurricane-resistance and architectural appeal.
INNOVATION:
Two interior shear wall panels, each four stories high, were lifted into place. After the exterior three-story panels were erected, the steel contractor installed the columns, beams and fourth floor deck. The contractor then poured the fourth floor concrete, which was followed by the erection of the second-tier panels. An additional 15 panels, measuring 18 feet by 26 feet and weighing 60,000 pounds each, were lifted into place by a crane to add the fourth and fifth stories.
Curtain wall features on the corners, front and rear of the building add visual appeal to the structure. The large glass area and specialty splatter coat that emulates stone are striking. A creamy neutral color scheme complements the existing facilities.
Although the project was constructed during a particularly active hurricane season in which Florida experienced an unprecedented four hurricanes, no panels were lost or damaged because of the engineer and contractor’s bracing expertise and attention to detail during preparation for the storm.
This project was a 2006 Tilt-Up Concrete Association (TCA) Achievement Award Winner in the Office category. It was one of the first five-story Tilt-Up buildings in the United States.
Design and construct a 150,000-square-foot, four-story office building that is ready for occupancy within 12 months. Completed in 1996
DESCRIPTION
Interior load-bearing steel frame and exterior load-bearing Tilt-Up concrete panels.
INNOVATION
Although the project was originally conceived as a conventional load- bearing steel frame with precast concrete panels for the exterior cladding, preliminary estimates exceeded the project budget and schedule. Steinbicker and Associates was brought in to consult on a Tilt-Up option based on their previous multi-story experience.
The suggested solution included the use of 8-inch thick load bearing Tilt-Up panels for the exterior walls. The Tilt-Up panels replaced the perimeter steel frame and precast concrete panels, resulting in significant cost savings. Cast on site on the floor slab and casting slabs, the Tilt-Up panels were designed to be stacked vertically in a 3+1 arrangement. This allowed the fast-track project construction to be phased to meet the aggressive schedule. The final result was an attractive multi-story office building constructed within the required schedule and budget.
Design and construct an air traffic control tower that is durable and resistant to hurricanes while meeting demanding time schedules and budgets. Completed in 2002
DESCRIPTION:
The walls were divided vertically into 25-foot-by-20-foot wide panels. In addition, interior floor slabs were constructed on site and then installed during construction.
INNOVATION:
Innovation was not limited to the design process, but applied during construction as well. The first four panels were tilted into place, and then two concrete floors – constructed on the ground – were slid down into place. The next four panels were then tilted into place on top of the original four panels and braced to the second floor slab. The next two floor slabs were then dropped into place prior to setting the next tier. The benefit to this system was the use of a smaller crane and braces, as the braces never had to handle more than 20 feet of panel.
The tower was designed for maximum durability – to include a 125-mile-per- hour wind load and exposure category D with an importance factor of 1.15, meaning that this tower should not only stay intact during a hurricane, but fully operational afterwards. The control tower cab, or working floor, was designed as a space frame to allow full assembly on the ground and was then lifted into place on top of the panels.
Both the owner and contractor were pleased that this project came in ahead of schedule and under budget. This project was a 2005 Tilt-Up Concrete Association (TCA) Achievement Award Winner in the Special Projects category.
