The first of three phases of the Terminal 3 Modernization Program at Phoenix Sky Harbor International Airport was completed in December 2016. The terminal was first built in the 1970s. The Terminal 3 Modernization Program covers 1.9 million square feet and is budgeted at $560 million. Phase 1 of the program accounts for 334,198 square feet for $150 million. The airport is remaining operational throughout construction.

Phase 1 is LEED Silver certified and includes renovating and expanding the terminal’s main passenger processing area, opening the existing concrete facade, an aluminum and glass façade, interior finishes and expanding the baggage claim area. Atriums at the departure and arrival areas provide transparency.

To open the structure and create an expansive passenger hall with centralized amenities, large sections of existing pre-cast concrete façade and mezzanines were removed. Some pre-cast concrete stair towers were preserved. A new façade was built with aluminum composite material (ACM) panels, ACM shade fins and curtainwall. The design contrasts existing textured concrete with the metal and glass envelope system.

Steve Rao, AIA, LEED AP, is president at DWL Architects + Planners, which also designed the original terminal in the 1970s. “We kept the structure of the old terminal we designed back in 1978, retaining its good bones,” he says.

Compared to the previous passenger hall, the new passenger hall has higher volumes, more views and more daylight. To fill the space will daylight, Kovach Building Enclosures installed its curtainwall and Acurlite Structural Skylights Inc. installed 14 of its skylights.

Mark Roddy, FAIA, LEED AP BD+C, design director at SmithGroupJJR, says, “We took what was a very inwardly focused building and made it externally focused, celebrating the beautiful Sonoran Desert landscape.”

ACM was used for a rainscreen, shade fins, roof grating, column covers and smoke screens. Kovach Building Enclosures installed 79,013 square feet of its Kovabond KRS-225 ACM in a 2 1/4-inch thick rainscreen system at walls, soffits and parapets. The ACM panels have a 6-mm fire-rated core and are finished in Sunstorm Silversmith. The face side of the panels has a three-coat, 1.6-mil-thick Kynar 500 gloss coating. The backside is finished with a 0.5-mil-thick wash-coat.

Kovach Building Enclosures installed diagonal shade fins on the west and south sides of the terminal. The fins are 1/8-inch perforated ACM with 0.191-inch round holes, 0.297-inch centers in a 60-degree pattern with 37.51 percent open area. They are finished in PPG Industries Inc.’s Duranar Sunstorm SilverSmith and UC1132 clear coat. The fins are attached to the building with aluminum knife plates and aluminum tube frames that stand off the face of the curtainwall by 15 inches.

Phase 3 of the Terminal 3 Modernization Program will encompass renovating and expanding the existing 10-gate north concourse. Like the south concourse in phase 2, it will have additional retail space and other amenities. Phase 3 is scheduled to be completed in 2020.
