The Franklin Academy, a 57,196 sq. ft. project, consisted of a two story classroom and a gymnasium building. This charter school contained many different components including Tilt-Up, masonry, structural steel, bar joists and hollowcore planks. This required many different types of structural connections between the Tilt-Up panels and the other structural units including dovetail slot that was cast into the panels to receive masonry ties.
Why was Tilt-Up selected for the project?
A 540′ long privacy wall, screening the school from adjacent residences, was converted to Tilt-Up construction. This provided a more economical solution to precast and was a more sound, maintenance free alternative to CMU and Stucco.
While zoning and permitting delayed the start of this project, the use of Tilt-Up construction enabled the entire shell to be completed in less than 90 days allowing the school to open in time for fall classes. It provided an alternative to the public school system and eliminated the need of busing for many students.
The panels featured a wainscot of 24″ x 16″ chiseled stone pattern formliner and a variety of different width rustications. Most of the windows were set in recessed areas with bordering reveals and many of the recesses were arched requiring that high density overlay plywood be cut in curved strips, installed onto the casting surface, and then trimmed out with PVC chamfer to achieve the desired appearance.
The number of “pieces” was kept to a minimum by increasing the width. Many of the panels were between 28 and 35 feet wide. While this required the use of a 300 ton crane, it ultimately reduced the erection time.
