Trierweiler Construction & Supply Co., Inc. was started in 1915 by William Trierweiler. William and his five-man crew replaced the wooden sidewalks in Marshfield, WI with concrete. in the "early" days, concrete was mixed by hand and hauled to the sidewalk forms with wheelbarrows. Other early projects included a street paving project in Oconto Falls, Wisconsin.
In 1947, Trierweiler Construction & Supply Co., Inc. became a corporation in the State of Wisconsin. Also at this time, Robert and Edward joined their father and the company began contracting with the Wisconsin Department of Transportation for highway work.

Upon William's death in 1970, the four brothers continued to grow and expand the business until their retirements.
