Aviation also is a significant component of JMT's business plan. The firm has a presence at airports in Washington, D.C., Baltimore and Philadelphia.

Since 1999, it has been involved in nearly $2 billion in projects at Baltimore Washington International Airport, providing comprehensive architectural and engineering services in design and project management.

JMT is program manager of BWI's $350-million Runway Safety Area, Pavement Management and Standards Compliance Program. As part of that program, JMT managed pavement rehabilitation at an intersection of two major runways.

The project required nearly two years of coordination with airlines to schedule runway closures. The project team was able to complete pavement resurfacing and re-profiling work at the intersection during a 54-hour period of continuous closure.

"When we first came to BWI, a lot of people said that project was impossible—you couldn't close that intersection," says David Lookenbill, JMT senior vice president and aviation practice leader. "We worked in partnership with the stakeholders to make it happen."

Paul Shank, Maryland Aviation Administration chief engineer, says that as a program manager JMT is "an extension of staff" at BWI. "They have proven to be our best full-service consultant," he says. "Being a state agency, we truly embed consultants into our operation and they are a go-to firm here."

Transportation still accounts for 85% of JMT's revenue, but the water, wastewater and utilities sectors also have become significant contributors. The firm saw its 2014 water/wastewater revenue more than double, thanks largely to work at Back River Wastewater Treatment Plant in Baltimore. JMT's current work there includes a new 800-million-gallon-per-day headworks facility.

JMT president, Jack Moeller, sees prospects for even more growth in water and wastewater. "A lot of areas around the country are under [federal] consent decrees," he says. "They have the old storm drains and sewer lines that need to be separated."

Moeller adds, "That work will continue for a while. Plus, [there is] the fact that you see failures in these water and sewer lines that are 100 years old. That will be a growth field for a while."

JMT also sees growth possibilities in its buildings and facilities practice. For more than a decade, the firm has worked on building projects with government, education, commercial and health care clients.

Acquisition Activity

Last October, JMT took another step to expand. It announced that it had acquired Rubeling & Associates, an 18-person architecture and interior design firm based in Towson, Md. Rubeling & Associates is now a division of JMT with Al Rubeling Jr. serving as senior vice president.
