Our Company

Thieneman Construction is a premier environmental contractor, building municipal and industrial water and wastewater facilities.

Thieneman Construction is dedicated to exceeding client expectations by producing at a high level of quality and safety, meeting project deadlines and offering fair pricing. We take responsibility for every project from conception through completion and we self-perform the majority of the work: earthwork, structural concrete, yard pipe, process equipment, metals installation, and exposed mechanical. This allows us to closely manage our projects which maintains our competitive edge and offers employees a broad range of opportunities

We know that relationships are built on trust through hard work, integrity and a passion to build relationships not just projects. A true general contractor, we provide extensive experience in value engineering and the expertise to "think outside the box" on our projects which provides valuable savings for our clients.

Established in 1999, we currently operate from two office locations in Westfield, IN and Merrillville, IN.

The project consisted of two basins using 6,100 cy of concrete and a 15M gallon capacity. The sides of the basin had a slope, which made the concrete mix design very critical for the application.
