The Coral Baptist Church expansion features a 2,000-seat sanctuary with stadium style seating, early childhood learning rooms, a chapel and church administration offices. The church places a major focus on audio visual equipment, as well as lighting and camera coordination, and produces their message in a theatrical production setting. The Tilt-Up portions of the project include several radiused panels that step in and out to create the lobby area that followed the contour of the main sanctuary. Tilt-Up was also used to create the stair-stepped bearing elements for the support of the stadium style seating in the sanctuary, while creating corridors from the main lobby and hallways into the theatre. Full height load bearing Tilt-Up panels enclosed the full sanctuary area while utilizing large spandrel panel sections spanning over the soundstage, one of which is 65 feet, 2 inches wide weighing in excess of 150,000 pounds. All of the Tilt-Up panels support the roof structure of clear span truss girders at elevations of 52-plus feet. In addition, spandrel panel sections were used to accommodate the many roof elevation transitions that help create architectural separation of the building's support structures from the main sanctuary.

Leander Independent School District made the decision to procure this project using the design/build delivery method. This provided a unique opportunity for each proposer to choose the best building systems to meet the needs of the project. The contractor chosen selected a high performance design using insulated Tilt-Up with formliner, self-consolidating concrete and a unique staining process to provide an exterior finish that is both durable and matches the surrounding natural stone. The insulated Tilt-Up system is also uniquely durable on the interior and provides superior structural performance and thermal efficiency. The final project included more than 152 Tilt-Up wall panels and 13 individual structures. The 13 structures on the complex consist of a press box, two field houses, two concession buildings, two ticket booths and six restrooms. Tilt-Up construction was not limited to the 13 structures: Tilt-Up construction was used at the main entry, "stampede panels" for concealing the rolling gates when in the open position and under the press box "airplane panels" as an aesthetic feature. The dumpster enclosures and the walls on each side of the stairs leading down into the field were also Tilt-Up panels. The Tilt-Up panels at Gupton Stadium are sandblasted, painted, stained or a combination of the three.

Surrounded entirely by desert, the library and nature center is located at the entrance to White Tank Mountain Regional Park. The exterior is patterned and colored to blend into the desert plant life. Architect interpretations of local petroglyph designs are also part of the building design aesthetic. Tilt-Up was selected as the primary structure type mainly due to the method's cost effectiveness. However, the thick concrete walls act as a heat sink taking advantage of the thermal lag effect. The massive concrete walls store the sun's energy and slowly release it at night, modulating the buildings temperature swings and in turn reducing the building's energy loads. An interior liquid air barrier, studs, and Batt insulation was added to further reduce the transfer of heat. Another reason for choosing Tilt-Up was the building envelope uses high recycled content in the rebar and concrete. Finally, the long and deep shade fins, which continuously shade the panoramic library picture windows, significantly reduce the heat gain in the building by shading the glass for a large majority of the day, conserving energy use. The building's 200-foot-long monolithic concrete wall, diagonally subdivided into abstract shapes, is colored in three shades of green to match surrounding Saguaros, Palo Verdes and Mesquite trees. This project has achieved LEED Platinum certification.
