Elementary school earns good grades with three-tier
The expansive, new
500-student, pre-K through fourth-grade Heritage Elementary School
in Tahlequah, Okla., was greatly needed by its growing community.
The project, designed by Crafton Tull Architects in Tulsa, Okla.,
features a curving spine element that provides the main circulation
corridor off of which three major classroom "fingers" radiate.
A defining entry area of the 70,000-squarefoot structure honors
Tahlequah's Cherokee Indian history with a representation of the
Cherokee sacred fire, a symbol of the culture's unity and strength.
Enrollment at Tahlequah Public Schools includes approximately 44
percent Native American students.
According to Crafton Tull Architects, the structural system for
the classroom wings consists of metal roof trusses, steel beams and
exposed cantilevered concrete columns. The truss system was
supplied by Sooner Steel & Truss, Oklahoma City. The remainder
of the projects consists of structural steel framing, precast
panels and glue-laminated wood, which were also utilized at the
entry tower element of the building.
Nearly 87,000 square feet of Elk Grove Village, Ill.-based
Petersen Aluminum Corp.'s 24-gauge PAC-CLAD Galvalume Snap-Clad
metal roof panels were selected to cover the sprawling structure.
The innovative roof design on each classroom wing features three
different levels that minimize mass and offer a sleek look. The
Snap-Clad panel profile was specified as an option by the
architect, says Jason Irvin, branch manager of Harness Roofing,
Tulsa, the installing contractor.
"The detailing was
complicated and required custom-tapered valleys and transitions
from each level of the wings," Irvin says. "[We] worked with the
architect and Petersen on designing valleys at transition levels.
Getting the levels to line up properly was definitely a challenge.
But other than that, the job was relatively straight-forward. There
was just a lot of it!"
Irvin and his coworkers attended weekly meetings with the
general contractor and architect to discuss progress and adjust
details as the project progressed. "[We] designed and fabricated
custom gutters due to increased size of gutters," he says. Many of
the Snap-Clad panels were up to 60 feet long and were fabricated
on-site using Petersen's portable roll-forming equipment provided
from its Tyler, Texas, plant. "The longer panels were lifted onto
the roof using a crane and spreader bar," Irvin says. "The shorter
panels were manufactured in Tyler, crated and shipped to us."
