McCleary Engineering
McCleary Engineering specializes in geotechnical investigations and recommendations for foundation design, retaining walls, slope stability, embankments, pavement design and rehabilitation, subgrade treatments and other engineering services such as drainage studies. McCleary Engineering is Illinois Department of Transportation (IDOT) prequalified in general geotechnical services, subsurface explorations, structure geotechnical reports and construction inspection categories.
Mr. McCleary has nearly 19 years of construction and geotechnical engineering experience with IDOT. Six years were spent on the front lines of contract administration in construction as a resident engineer on bridge and roadway projects which included construction layout, material inspection and construction practice inspection. For the last 13 years at IDOT, Mr. McCleary was the District #3 geotechnical engineer, working with hands-on subsurface investigations; analysis, design, and inspection of geotechnical engineering projects; and on-the-spot problem solving. He has served on numerous statewide committees involving abutment design, piling, aggregate subgrade, subgrade stability, pavement under drains and pavement rehabilitation. He served on a nationwide Federal Highway Administration (FHWA) pooled fund study on deep soil mixing technology. In 2009, Mr. McCleary left IDOT to work full time at his company, McCleary Engineering. Mr. McCleary is a licensed professional engineer in the states of Illinois, Indiana, Iowa, Georgia, Montana, Michigan, Ohio, Oklahoma and Wisconsin. He is a member of the American Society of Civil Engineers, the National Society of Professional Engineers, the Deep Foundations Institute, the Pile Driving Contractors Association and the Illinois Association of Highway Engineers. He is currently serving on the NCHRP Committee for the research of bridge scour on gravel bed rivers.
