What Bkl does

BKL, Inc. is a privately held, employee-partner-owned architecture, civil engineering, and structural engineering firm headquartered in Tulsa, Oklahoma. Founded in 1946 as Fell and Wheeler, Consulting Engineers, the firm underwent several renames and was acquired via management buyout in 1998 by Kim Reeve, George Rochelle, and Stacy Loeffler, who rebranded it as BKL, Inc. Today the firm operates from the historic TulOil building purchased in 2008 and is led by President Jenni Hammock (since 2024) alongside Principal Ryan Mahaffey (Civil Engineering, partner since 2022) and Principal Stacy Loeffler (Structural Engineering, with the firm since 1987).

BKL provides integrated architecture, civil engineering, structural engineering, interior design, master planning, and construction administration services, delivered in-house to eliminate cross-firm handoffs. Its technical stack centers on industry-standard BIM tooling (Revit, Bluebeam, and BIM 360/ACC) applied to civic, judicial, detention, public safety, transportation, and water/wastewater projects for government clients. Representative engagements include the 104,000 SF Rogers County Courthouse, the Broken Arrow Public Safety Complex, the Owasso Fire Station No. 3, the Mayes County Fairgrounds, and ODOT/OTA highway rehabilitation work on Tulsa's Inner Dispersal Loop.

BKL earns revenue through project-based professional services fees billed to municipalities, counties, and state agencies across Oklahoma. The firm is selected through competitive interviews and public RFP processes, with repeat engagements driven by long-standing relationships. It holds SBA 8(a), WOSB, DBE, and HUBZone certifications, which expand its access to set-aside contracts in federal and state procurement. Its marketing relies on a portfolio website, Instagram presence, an annual client event (BKL Fest), and direct enterprise field sales targeting Oklahoma public-sector buyers.
