Jonathan Kothe

Jonathan Kothe serves as an Engineer I – Water within the Illinois Engineering Agency, where he plays a pivotal role in the procurement and technical oversight of water and sewer infrastructure projects. His responsibilities include evaluating engineering specifications, managing solicitation development, and ensuring compliance with state and federal standards for public works construction. He is instrumental in advancing the agency’s mission to modernize aging water distribution systems, mitigate combined sewer overflows, and enhance stormwater resilience through targeted capital improvements. Kothe primarily handles construction-phase acquisitions under the NAICS 237110 category, focusing on pipeline rehabilitation, pump station upgrades, and related civil works requiring specialized hydraulic and geotechnical expertise. While no contractor data is currently available, Kothe’s procurement patterns indicate consistent engagement with qualified civil construction firms possessing demonstrated experience in water infrastructure. His working relationships are built on technical credibility, adherence to design-bid-build protocols, and rigorous performance evaluation standards. He prioritizes vendors with proven track records in trenchless technology, pipe lining, and reinforced concrete structures, fostering long-term partnerships grounded in quality, safety, and regulatory compliance. Kothe’s contracting activity is entirely non-set-aside, with 100% of procurements open to full and open competition. This reflects a strategic agency-wide emphasis on maximizing technical capability and value through broad market engagement rather than socioeconomic set-asides. While small business participation is not formally prioritized in his portfolio, all vendors—regardless of size—are evaluated equally on technical merit, past performance, and capacity to deliver complex water infrastructure projects. His primary industry focus is NAICS 237110, encompassing the construction of water mains, sewer lines, pumping facilities, and associated appurtenances. Kothe’s technical expertise lies in municipal water system rehabilitation, including cast iron and PVC pipe replacement, CSO control structures, and gravity flow network enhancements. He routinely reviews engineering drawings, material certifications, and construction methodologies to ensure alignment with Illinois environmental and public health standards.
