Tenneson Engineering Corporation is now an AKS company

AKS Engineering & Forestry LLC (AKS) and Tenneson Engineering Corporation (TEC) announced the merger of the companies effective July 1, 2023. The merger expands the geographic reach of AKS while TEC gains additional resources and expanded capabilities.

TEC is a consulting firm based in The Dalles, Oregon, and White Salmon, Washington, that has traditionally served a wide range of clients from eastern Oregon and Washington to the Pacific Coast. Established in 1952 as Wall & Tenneson, the company was incorporated under its current name in 1959. TEC provides civil engineering, land surveying, structural engineering, land use planning, water rights, and construction support services. Their clients include local municipalities, special districts, ports, private landowners, and local developers along the Columbia River Gorge and throughout Oregon and Washington.

Tenneson will continue operating under the same name for the next few years and will eventually transition to be known as AKS. As part of the transition, the staff of TEC joined AKS, and TEC co-owners Ben Beseda, PE, PLS and Darrin Eckman, PE became owners in AKS.

Beseda joined TEC in 1994 after graduating from Portland State University with a Bachelor of Science in civil engineering. He has served as president of TEC and is responsible for land surveying operations. He is a registered professional civil engineer and land surveyor in Oregon and Washington.

Eckman came to TEC in 1996. He graduated from the University of Portland with a Bachelor of Science degree in civil engineering. He has been serving as vice president and is responsible for engineering operations. Eckman is a registered professional civil engineer in Oregon, Washington, and California.

“When we first met Ben and Darrin and their team, it was clear this would be a perfect fit. We provide very similar services, have the same common values, pride ourselves on quality work, and want to continue serving our employees, clients, and communities. This will prove to be an excellent partnership and opportunity for AKS, TEC, and our clients for years to come,” noted AKS Managing Member, Blair Carlson.

The company offers in-depth expertise and resources in civil engineering, water resources, surveying, and land use planning.
