Tetra Tech Expands its Aviation Technology Solutions with the Acquisition of BridgeNet

Tetra Tech, Inc. (NASDAQ: TTEK) announced today that it has acquired Bridgenet International Inc. (BridgeNet). BridgeNet is an aviation technology solutions firm based in Newport Beach, California, that is focused on aerospace data analytics, environmental and acoustic consulting, and 3-dimensional airspace visualization for federal and commercial aviation customers.

BridgeNet develops, sells, and supports its proprietary software, Volans, a web-based 3-dimensional application designed to create, evaluate and display flight operations. This tool enables engineers and aviation experts to simulate and display potential acoustic and environmental impacts from new performance-based navigation procedures and flight operations, as well as runway and airfield configurations. Volans is being used throughout the world, including in the United States, Canada, Australia, France and England.

“New performance-based navigation systems require more advanced assessment and management tools,” said Dan Batrack, Tetra Tech’s Chairman and CEO. “By combining the expertise of Tetra Tech and BridgeNet, we have expanded our ability to provide technologically differentiated solutions for life-cycle aviation services from airspace and ground support to environmental and aviation demand modeling and forecasting worldwide.”
