What Dr. Schleicher + Partner Ingenieurgesellschaft mbH does

Dr. Schleicher + Partner Ingenieurgesellschaft mbH is a privately held German engineering consultancy founded in the 1950s in Gronau (North Rhine-Westphalia), with a second office in Lingen (Lower Saxony) established in 1972. The firm delivers four core service lines — Baugrund/Geotechnik (soil reports, foundation consulting, drilling investigations, settlement calculations), Umwelt/Altlasten/Bauschadstoffe (contaminated-site investigations, asbestos surveys, demolition planning and supervision), Hydrogeologie/Wasserwirtschaft (groundwater exploration, water-rights applications, pumping and infiltration tests), and Gebäuderückbau/Sanierung im Bestand (building deconstruction with hazardous-material management). Clients include industrial companies, energy suppliers, renewable-energy developers, federal and state transport authorities, municipalities, associations, and private customers in NRW, Lower Saxony, Münsterland, Emsland, Schleswig-Holstein, and Brandenburg; flagship engagements include geotechnical reports for more than 1,000 wind turbines since 1998, ongoing work at Europe's largest gas-cavern storage facility in Gronau-Epe, and emergency-response consulting on the Epe S5 crude-oil spill remediation.

The firm operates its own soil-mechanics laboratory and a full suite of geotechnical field-investigation equipment (small-diameter drilling, CPT, dynamic probing, concrete/asphalt core drilling, geophysical measurements), and uses GIS/GPS surveying, drone-based aerial documentation, and digital groundwater data loggers. It holds specialized regulatory certifications including Sachverständiger nach § 18 BBodSchG, Sachkunde nach TRGS 519 (asbestos), Fachkunde nach TRGS 524 / DGUV 101-004, Bodenkundliche Baubegleitung (BBB), and LAGA PN 98 sampling credentials, which are legally required for certain public-sector and contaminated-site engagements.

Revenue is generated on a project-by-project basis through direct consulting engagements, with new work acquired via direct client outreach, public tenders, and long-standing regional reputation. The firm is led by three managing directors — Diplom-Geologe Andreas Beunink, M.Sc. Geow. Thomas Helmes, and M.Sc. Geow. Kai Nieland — who jointly assumed leadership in 2019. Pricing is quote-driven per engagement and not publicly disclosed; no external investors, funding rounds, subsidiaries, or M&A activity are reported.
