A growing presence at the right time can mean so much to a company. CrownAir Aviation, a full-service fixed base operator (FBO) at Montgomery Executive Airport in San Diego, has learned this during its 70-year history. CrownAir Aviation recently added an FBO office and two hangars to its site. One entrance to the office building features a curved arch created with Flex-C Trac and Flex-C Angle from Flex-Ability Concepts.

"A simple detail like an arched entrance can be functional by telling people where to go while also serving as a design element that is inviting," said Robert Widmer, marketing manager of Flex-Ability Concepts. "Curves break up the scale of a building, like a large office space, and distract from the linear nature of lines."

JMS Interiors Inc., Santee, Calif., installed 16-gauge 3-5/8" Flex-C Trac and 16-gauge Flex-C Angle. They worked with general contractor Dempsey Construction, Carlsbad, Calif. Flex-C Trac and Flex-C Angle were distributed by Foundation Building Materials, San Diego.

Garrett McKillip, an estimator with JMS Interiors, said the products were chosen for ease of use and a quick install. JMS Interiors, a drywall and framing contractor that has served the San Diego area for more than 10 years, has used Flex-C Trac in the past. McKillip said the crew was challenged on this project by maintaining the radius dimension. This was made easier with Flex-C Trac’s and Flex-C Angle’s Hammer-Lock feature. Only available with Flex-Ability Concepts' products, the Hammer-Lock tabs are hammered into place to embed them into the web and secure the shape of the products. For added strength, self-tapping screws can be embedded into the side of Flex-C Trac or Flex-C Angle. Labor and material cost savings are among the greatest product benefits compared with traditional methods used to create curves.

The 2-story, 16,452-square-foot FBO office building replaces previous facilities that were demolished. The two hangars total 14,000 square feet. The site also features a new parking lot, landscaping and hardscaping, sewer and fire water lines, and bio-filtration areas. The airport remained opened while the phased construction progressed.
