New Aviation Services

We are pleased to announce an expansion of Horrocks Engineers’ aviation services and the appointment of Lee Underwood as Aviation Manager. 

Horrocks has supported local, state, and federal entities on a variety of airport projects. These projects include land and airside civil engineering for the Salt Lake City International Airport Terminal Redevelopment Program and program management for the Williston Basin International Airport project in North Dakota, which was the last commercial greenfield airport completed in the United States and the fastest from conception to operation. We are now positioned to offer an even greater depth of services for aviation infrastructure projects.

Lee Underwood, PE, brings more than 35 years of aviation experience to Horrocks and has worked on airside and landside projects in 12 states and in Saudi Arabia. He has completed substantial aviation jobs, including military projects and a $7 billion design-build for an international airport. With Lee’s industry expertise, we have expanded our aviation services to include more program management, larger and more complex airside designs, and U.S. Department of Defense projects.

Throughout 2019, airport use was at an all-time high. According to the Bureau of Transportation Statistics (BTS), U.S. airlines and foreign airlines serving the U.S. carried “an all-time high of 1.1 billion systemwide (domestic and international) scheduled service passengers in 2019, 3.9% more than the previous annual record high of 1.0 billion reached in 2018.” U.S. Secretary of Transportation Elaine L. Chao cited data from the Federal Aviation Administration (FAA) in a November 2019 address: “U.S. civil aviation supports more than 5% of U.S. gross domestic product; $1.6 trillion in economic activity; and nearly 11 million jobs.” Funding has also increased significantly in recent years as Congress has prioritized rebuilding and refurbishing our country’s critical infrastructure. In spring 2020, some airports have chosen to accelerate infrastructure programs to take advantage of reduced passenger numbers due to COVID-19.

Horrocks is already providing aviation services to meet client’s needs, and we look forward to providing even more benefit to current and future clients through these additional services.
