What Benham does

Benham is an architecture, engineering, and design-build firm headquartered in Oklahoma City, founded in 1909 and operating as a wholly-owned subsidiary of Haskell since April 2016. The firm delivers integrated planning, architectural design, multi-discipline engineering, and turnkey construction services under three core offerings (Architecture, Engineering, DesignBuild), with in-house capabilities spanning civil, structural, mechanical, electrical, process, packaging, and process controls engineering. Benham employs over 400 professionals across six U.S. offices (Oklahoma City, Tulsa, Houston, St. Louis, St. Paul, Charlotte) and operates additional capacity through joint ventures.

The firm serves a dual public-private client base, with federal, state, and local government contracts described as high priority for over 100 years. Marquee federal customers include all branches of the Department of Defense, the U.S. Army Corps of Engineers (multiple districts), the National Guard Bureau, the FAA, the Department of Veterans Affairs, and multiple state DOTs, accessed through IDIQ contract vehicles. On the commercial side, Benham serves consumer products and food & beverage manufacturers (Dr Pepper Snapple, Boral Bricks, Metal Container Corporation, Monsanto), executing projects such as a 57-acre bottling facility, the largest brick manufacturing plant in the United States, and a 500-million-container-per-year aluminum bottle line. Revenue is generated through professional services fees and design-build project delivery (fixed price, cost reimbursable, GMP, and hybrids), with no public pricing disclosure.

Technology deployment centers on Building Information Modeling (BIM), 3D CAD, simulation modeling, the proprietary PCASE pavement design software, and ISO-9001/ASME-NQA-1 compliant Quality Management Systems. Benham has received multiple DBIA National and Regional Excellence Awards, ACEC engineering awards, USAF Honor Awards, and LEED Gold/Silver certifications, reflecting sustained third-party validation across aviation, military, civil infrastructure, and industrial projects.
