Firm History

BKL’s roots reach back to 1946 when William J. Fell co-founded Fell and Wheeler, Consulting Engineers, in Tulsa.  Through the years we have been involved with many high profile projects in the region.  We were on the original design team for the Tulsa Port of Catoosa, and in 2016 were selected as their current on-call engineering and architecture firm.  Our firm was one of the core group of firms that design the Tulsa Metropolitan Expressway System Master Plan.  We were the Architect of Record for the David L.
