the engineering office “Ingenieurbüro Manzenrieder/Witte” (IMW) was founded by Dr. Helmut Manzenrieder immediately after completion of his doctorate under the professorship of Prof. A. Führböter (Leichtweiß-Institute of TU Braunschweig). Initially the office was located at the home of the family Manzenrieder at Husbrok 27 in Oldenburg.
the office was renamed to “Ingenieurbüro Dr.-Ing. Manzenrieder und Partner” (IMP) and registered as a partnership under civil law (GbR) after the intended entry of Dr. H.-H. Witte did not happen.
the company seat moved to a dedicated office building at the Brookweg 29 in Oldenburg, where also the company Argus “Gesellschaft für Umweltmesstechnik mbH” (Argus) moved which was founded in 1990. At this time about five people worked for IMP.
Dr. Frank Spingat joined IMP as a senior employee after receiving his doctorate at the Leichtweiß-Institute of TU Brauschweig, too.
the positive development of the company required relocation to a bigger, newly erected company building at Bollmansweg 8 in Oldenburg where also the company Argus was domiciled until the transfer of its company seat to Ritterhude in Bremen in 2001. The companies share a close relationship since this period which has been reinforced by many joint projects and lasts until today.
Dr. Manzenrieder retired and handed over management of the engineering office to Dr. Spingat, who since then heads the office under a new name and new legal form as “IMP INGENIEURE GmbH & Co. KG”. Likewise the new company structure still provides its services as a completely independent office and sees itself as a flexible service provider with an extensive spectrum of activities pertaining to water.
