TriMet taps Dorn as head of engineering, construction and planning

The Tri-County Metropolitan Transportation District of Oregon (TriMet) last week announced Mark Dorn as the new executive director of engineering, construction and planning.

Dorn has more than 20 years of experience in multimodal transit planning and has overseen the engineering and construction of light-rail, streetcar and bus rapid-transit systems across the country since 1992, TriMet officials said in a press release.

In his new role, Dorn will lead upcoming projects and oversee the execution and administration of state and federal safety reviews, they said.

Most recently, Dorn was the director of transit design and engineering for David Evans and Associates Inc. He previously worked for AECOM and engineering firm URS Corp., handling transit projects in Oregon, California, Oklahoma, Pennsylvania, Washington, Michigan and Georgia.

"Through his work as a consultant on large transit projects, Mark has cultivated a rich history in transit around the region and the nation," said TriMet General Manager Sam Desue Jr. "His extensive knowledge surrounding project delivery will be a significant asset to our engineering, construction and planning teams and TriMet as a whole."
