“Oklahoma is my home, and I’ve spent my career working to make it the best it can be. I’m excited to work for a firm that has deep roots here and shares that commitment to community,” Buchanan said.
Over his 15 years in the transportation industry in Oklahoma, Buchanan has cultivated expertise in both construction and design. He brings with him an understanding of the state and a passion for helping to solve its most pressing transportation challenges. His experience includes a range of projects from rural highway widening projects to large urban interchanges. He has specific skills in constructability and phasing of large urban expressways and interchanges that stem from his experience in the construction sector. Significant projects include the I-44 Interchange at US-75, I-444 from I-244 to US-75 (south leg of the Tulsa IDL), and the SH-51 and US-177 Intersection replacement and bridge over Boomer Creek in Stillwater.

He’s well-respected and trusted in the industry and has consistently demonstrated his technical skills and expertise,” said Transportation Team Leader Jenny Sallee, PE. “His design and construction experience will be an enormous asset as we continue to be our clients' most trusted advisor.”
Buchanan’s project management skills include contract administration, cost estimating, subconsultant agreements and coordination, team and production management, and presentations for public/tribal/stakeholder meetings. His design experience includes geometric design and modeling for highways and intersections, drainage design, construction sequencing, estimating, quantity calculations, and right of way documents.
