Gewalt Hamilton, Civil Engineers, Office space

Gewalt Hamilton has gone from a two person home office to a thriving, well-respected corporation.

Gewalt Hamilton was founded in 1981, specializing in civil engineering. In a small home office in Lake Bluff, Illinois, the firm began with two engineers, Dave Gewalt and Bob Hamilton, driven to deliver service that exceeded clients’ expectations. Through decades of diversification and growth, we have added quality professionals in complementary service lines to our firm, resulting in added depth and strength.


Today, Gewalt Hamilton is a multi-disciplinary organization providing comprehensive services in the fields of Civil Engineering, Land Surveying, Construction Engineering, Traffic Engineering and Transportation Planning, Traffic Data Collection, and Environmental Consulting.
