What CALHOUN-BURNS AND ASSOCIATES, INC. does

Calhoun-Burns & Associates, Inc. (CB&A) is an Iowa-based civil and structural engineering firm founded in 1982 and headquartered in West Des Moines. The company provides bridge inspection, bridge and culvert design and rehabilitation, construction observation and administration, and special project services to counties, municipalities, and the Iowa Department of Transportation. CB&A is described as the leader in Iowa for bridge inspection and load rating analysis, with engineers certified as Team Leaders or Program Managers conducting more than 10,000 biennial bridge inspections statewide and serving 150+ communities each year. The firm has completed more than 2,200 bridge, culvert, and roadway projects since inception, with technical specialization in continuous concrete slab bridges, pretensioned prestressed concrete beam bridges, reinforced concrete box culverts, and special structures such as trail bridges, observation towers, and historic covered bridges.

The business operates on a professional services model, billing Iowa government clients on a project basis, often involving Federal Highway Bridge Replacement and Rehabilitation Program funding administered by the Iowa DOT. Its go-to-market is relationship-led and geographically concentrated: CB&A develops long-term direct relationships with county engineers, municipal public works departments, and state DOT officials, and has coordinated with Iowa DOT, FHWA, Iowa DNR, Iowa Homeland Security & Emergency Management, and the U.S. Army Corps of Engineers for more than 30 years. The firm's value proposition rests on its domain expertise (rehabilitation vs. replacement evaluation), funding-program assistance, and full-service capabilities spanning inspection through construction administration.

In the early 2000s, CB&A combined with Veenstra & Kimm under a common public service commitment. In April 2025, both firms were acquired by Kleinfelder, a leading engineering, design, construction management, construction materials inspection and testing, and environmental professional services firm founded in 1961 that employs more than 3,300 professionals across 110+ offices in the United States, Canada, and Australia. CB&A now operates as a Kleinfelder company, retaining its Iowa-focused bridge and culvert practice while gaining access to Kleinfelder's broader service portfolio and geographic footprint.
