Arne P. Johnson



Arne Johnson joined WJE in 1989 after working for a structural design firm in Chicago. At WJE, he has investigated several hundred concrete, steel, masonry, and wood structures. Most assignments have involved evaluation of structural capacity, deterioration, distress, or failure; many have included design of repairs, construction documents, and construction observation.

Mr. Johnson has particular expertise in evaluation and repair design for historic structures, including repair and protection systems for aging concrete. He has extensive experience evaluating and repairing wood structures. Mr. Johnson also has expertise in vibration testing and monitoring to protect structures from construction-related vibrations.

Mr. Johnson has performed numerous insurance-related investigations involving structural failures, fire damage, wind damage, vibration damage, and foundation settlement. He has also conducted many structural design peer reviews and load-rating studies.
