T-O Engineers, a full-service planning and engineering firm, is proud to celebrate 30 years in the aviation sector. Founded in 1984, T-O Engineers initially provided civil services primarily to land development and transportation clients. In 1988, T-O Engineers acquired Hosac Engineering and diversified their portfolio by adding aviation services to the company resume.

Three decades later, T-O Engineers serves 36 airports throughout Idaho, Washington and Oregon. Clients range from small general aviation airports to large commercial service airports. 

The gateway to Spokane’s community is our airport. T-O is excited to be a part of the forward thinking team at Spokane International Airport, which is focused on creating a positive passenger experience for both residents and visitors of the Inland Northwest.

T-O will lead the utility installation and relocation elements of this landmark project. We are currently designing the first package, which will be the backbone of this $130 million project!

The Southwest Idaho Chapter of Women In Transportation (WTS) awarded T-O Engineers 2017 Employer of the Year at their Awards Gala in February.
