Our construction experience. Your successful project.
Thieneman Construction is on a mission to lead the construction services industry in customer satisfaction and job site safety while helping to improve environmental sustainability through our projects.
Delivery Method: Design Bid Build
Project Size: 5-Million-Gallon Drinking Water Facility
Construction Value: $19.5 M
feet below grade between lake Michigan and university buildings.
owner requested work stoppages managed around university events (sports, move-in, etc.).
The City of Evanston needed to build a new 5-million-gallon reservoir tank at the clearwell drinking water facility to support an expanding population. High attention to detail was required to construct the 265’ x 145’ tank, 25’ below grade, positioned directly between Lake Michigan and a large student dorm. The project featured a complex 5 phase earth retention system. The project was completed ahead of schedule with both stakeholders pleased with the execution and results while navigating 9 project stoppages for university events because the project was located on Northwestern University property. Northwestern even brought their construction and engineering students to tour the jobsite multiple times.
Improving views, enhancing community aesthetics, and adding new public space. The project site, originally an aging parking lot that detracted from the aesthetics of the area has been upgraded to green space for the residents of the adjacent Northwestern University (NU) dormitories and the community. Converting a parking lot into green space has not only improved aesthetics, but has also added a new public space, and provided a safe area for bikers and walkers, allowing them to enjoy the view of Lake Michigan and giving them better access to the beach. Furthermore, adding green space is aligned with one of the key strategies in the city of Evanston’s climate action and resilience plan.
Meaningfully engaging stakeholders. The project team established sound and meaningful programs for stakeholder identification, early and sustained stakeholder engagement, and involved stakeholders—including regulatory organizations, nearby communities such as NU, and Evanston’s wholesale water customers—in project decision-making. As part of the temporary construction easement that was required to perform the work, a partnership between Evanston and NU was formed. Working together, the two partners effectively achieved solutions with respect to any issues with project plans and specifications.
Implementing an innovative design. The project utilized an innovative underdrain collection system that provides many benefits, including protection against damage to the Clearwell from underground uplift forces; protection of the potable water supply from groundwater contamination; and significantly lowered capital costs, lowered energy use, and lower operations and maintenance costs over the life of the project compared to constructing a new pump station that would be required for an above-ground Clearwell. To implement this innovative design, the project team needed to overcome barriers—barriers in the form of current regulations that no longer allow for clearwells to be constructed below grade. The team successfully obtained a permit to implement this design from the Illinois Environmental Protection Agency after demonstrating the benefits and safety of the design.
Protecting the natural world. This project is protecting the natural world in many ways, including:

in savings due to changes made to the project plan.
Delivery Method: Guaranteed Energy Savings Contract
Project: Wastewater Treatment Plant Improvements
Construction Value: $9 M
In 2019, Thieneman Construction Inc. was awarded the Yorktown Guaranteed Saving Contract for the Wastewater Treatment Plant Improvements located in Yorktown, IN.
The general project scope consists of furnishing all labor, materials, equipment, supplies and services for the construction and installation of a new Headworks Building, new effluent disinfection Building, and replacement of process equipment at the Primary Clarifiers, Secondary Clarifiers, aeration tanks and Biosolids Dewatering.
The project incorporated upgrades and improvements at all steps in the treatment process. Therefore, the work had to be sequenced in a way that did not interrupt overall plant treatment capability.
