(african proverb) Quality, adherence to deadlines, reliability, flexibility and innovative work Kollmer Bohr und Tiefbau GmbH is a medium-sized construction company run by the Kohl family. With our 200 employees we are on the road in southern Germany and handle projects in both inner-city and rural areas. Our main fields of activity are underground pipeline construction and civil engineering in general. We build water pipes, district heating and cooling pipes, gas pipes, sewers, power lines, telecommunication cables including the assembly of fiber optic and copper cables. In addition to classic civil engineering methods, we have been one of the pioneers in trenchless construction for 70 years. This includes press drilling up to DN1200, flush drilling up to DN600 in all soils and trenchers. We have already completed many projects in the rehabilitation of pipelines. Of course, the classic road construction in the context of village renovations is also part of our range of services. We are highly certified by recognized bodies such as the DVGW, the AGFW and the cable line civil engineering RAL. For many customers with a high level of quality requirements, we are prequalified and a so-called "preferred supplier". These include numerous municipal utilities, energy and telecommunications groups. Together with our employees, we always strive to provide innovative and high-quality work for our clients. In addition to business success, work safety, employee satisfaction and enjoyment of our craft are equally important to us. We build on the skills and motivation of our highly esteemed employees and strive to constantly improve our level through training and further education.

Nach einem tragischen Unfall des Juniorchefs wurde das Unternehmen im Jahr 1988 von Martin Kohl übernommen und zu einem modernen mittelständischen Baubetrieb ausgebaut. Seit 2008 ist Stephan Kohl in die Geschäftsführung des Unternehmens eingestiegen. Damit ist der Generationswechsel gelungen. Der Hauptsitz des Unternehmens heute ist in Kirchenthumbach (Nordbayern) mit den Zweigstellen in Grafenried und Frankfurt/Main. Zu den Stärken unseres Familienbetriebes zählen eine flache Hirarchie, innovatives Denken auf allen Ebenen und die Flexibilität auf Änderungen am Markt zu reagieren. Seit über 60 Jahren innovative construction, quality and competence in construction Our qualified employees, who are enthusiastic about what they do, make a significant contribution to this. They are the guarantee of positive development and progress in our company.
