What Kiefner & Associates does

Kiefner and Associates, Inc. is a private engineering and technical consultancy founded in 1990 by Dr. John Kiefner and headquartered in Columbus, Ohio. The firm specializes in pipeline integrity assessment, fitness-for-service evaluations, corrosion control, failure analysis, regulatory compliance consulting, and materials testing for oil & gas pipeline operators, gas distribution utilities, and state regulatory bodies across the United States and Canada. Since 2015, Kiefner has operated as the Engineering division of the Aegeus Group (a national technical assurance provider serving energy, defense, and aerospace) and also conducts business under the Applus+ commercial brand.

The company has built a 36-year proprietary software portfolio — KAPA™ (B31G pipe assessment), 5-7-9™ (crack assessment), PipeProps™ (49 CFR 192 material grade verification), Psqr (burst pressure analysis using Plausible Profile methodology), Pipelife Tool (cyclic fatigue), and the Surface Loading Calculator — paired with a state-of-the-art materials analysis laboratory and complex finite element analysis using Abaqus. These capabilities support a service mix spanning auditing, ILI program support, risk management, stress analysis, training/workshops, and emerging renewable energy services (hydrogen, CO2 capture, solar, wind). Customer evidence includes long-tenure engagements with People's Gas (cast iron study), the Illinois Commerce Commission, and the Colorado ECMC and PUC.

Kiefner generates revenue through project-based professional services contracts with quote-based pricing tied to scope and complexity. The go-to-market motion is direct enterprise sales targeting pipeline operators and utilities, supplemented by technical publications, content marketing, and conference presence at events such as the API Inspection and Mechanical Integrity Summit and the International Pipeline Conference & Expo. The firm maintains offices in Columbus (OH), Ames (IA), Longmont (CO), Golden (CO), Houston (TX), and Calgary (Canada), with a team of 11-50 specialists including PhDs, licensed Professional Engineers, and NACE/API/AWS/ASNT-certified technical authorities.
