Our story begins nearly 150 years ago, when Jeremiah Fruin, the son of an Irish contractor, founded Fruin & Company General Contractors in St. Louis, Missouri in 1872.
In 1900, Jeremiah Fruin took his son-in-law, engineer Redmond S. Colnon, into partnership, and the company changed its name to Fruin-Colnon Contracting Company. The company enjoyed decades of growth and extension of the company's field of activities; the engineering department was added in 1901.
The organization implemented a full-service strategy in 1940 that initiated the establishment of Fruco Engineering, the forerunner of Fru-Con Engineering Inc., as a subsidiary company.
Fruco Engineering served project owners and its sister company under design and construction contracts and assisted the construction company in providing single-source engineering, procurement, and construction services to its clients. During this time, engineering focus was placed on industrial projects.
During the post-war years, the now-named Fru-Con Engineering flourished and successfully built a reputation for quality services in the chemical, petrochemical, paper, pharmaceutical, cement, government and food industries.
In 1984 Bilfinger Berger AG assumed full ownership of Fru-Con and renamed the company Fru-Con Construction Corp. Fru-Con Engineering flourished as a business unit specializing in engineering services in many design-build and on site engineering projects.
In 2008, Bilfinger Berger Industrial Services, a subsidiary of Bilfinger Berger AG, assumed ownership of Fru-Con Engineering Inc. and changed the company’s name to BIS Frucon Engineering Inc. This realignment provided Frucon Engineering a clear role as an autonomous engineering firm specializing in specific market sectors with a continued focus on customer service.
