The firm expanded from Midwest roots into a national engineering consultancy.
It pioneered Midwest tilt‑up concrete in 1970 and later designed the world’s largest tilt‑up structure in Texas.
Its portfolio spans buildings, roads, water systems, and fall protection, including early bridge and roundabout projects in Ohio.
LJB delivers cost‑efficient structural design—especially tilt‑up, concrete, steel and wood structures—across North America, with licenses in all 50 states and Canada.
Safety by Design fall protection services grew from a 1994 project with GSA into a nationally recognized training and consulting arm.
Typical projects include large industrial facilities, airports, healthcare buildings, federal and municipal infrastructure, including iconic bridges and civil works.
Through strategic acquisitions of water resources and civil/survey firms, the firm continues expanding its sector depth and geographic reach.
