LJB

What LJB does

LJB Inc. is a privately held North American engineering firm founded in 1966 and headquartered in Miamisburg, Ohio. The firm provides multi-disciplinary engineering services across civil/site engineering, structural engineering, transportation, water resources, underground structures, survey, and GIS & asset management, with a distinctive specialization in fall protection and worker-safety consulting delivered through its LJB University training division. It also holds a category-leading position in tilt-up concrete structural engineering, with 65 Tilt-Up Achievement Awards — more than double any other structural designer. The firm sells engineering services on a project or retainer basis and standardized fall-protection training courses (Authorized Person, Competent Person at $1,800/person, and Qualified Person at $3,500/person) under two-year certification cycles aligned with OSHA, ANSI, and U.S. Army Corps EM 385-1-1 standards.

LJB serves six primary verticals — Commercial/Industrial, Education, Federal Government, Healthcare, Industrial/Manufacturing, and State/Local Government — through 20 offices across the US and Canada and professionals licensed in all 50 states. Named customers include Cincinnati Children's Hospital Medical Center, Bon Secours Mercy Health, Steel Dynamics, BNSF Railway, Norfolk Southern, and SwiftAir, with engagements spanning $600M healthcare facilities down to enterprise-wide OSHA compliance assessments covering 5,100+ fixed ladders across 15 facilities. Distribution is sales-led and relationship-driven: enterprise clients are acquired through direct engagement and government RFPs, while LJB University uses scheduled open enrollment (RegFox platform) plus custom team training for fall protection certification.

Since 2024 the firm has executed an aggressive acquisition strategy, completing Gorrill Palmer (April 2024, New England), Grantham & Associates (July 2024, Texas), and Aldea Services (2025, underground structures) within roughly twelve months — a roll-up that has expanded its geographic footprint to 19+ states and added underground engineering as a new service line. The company is management-owned with no disclosed private equity backing, and its ENR Top 500 ranking has improved from #300 in 2025 to #287 in 2026. A new president was appointed in 2025 to manage continued scaling.
