doubled performance

The service portfolio of Hetzel + Sponheuer GmbH & Co. KG has grown consistently in recent decades.

Besides “Classic Construction” (the core business), there are increasingly more services available for your building projects.

Hetzel Bau (Hetzel Construction)

with a comprehensive range of services covers all services and trades for your building projects. The company has been active since 1929. The roots lie in specialty coatings and removal tasks for large mining plants and energy companies. After 1945, focus was shifted to include retail stores and housing construction. In subsequent years, the preservation of buildings became increasingly important, (e.g. concrete maintenance). We were able, bit by bit, to develop new services. Today the company offers a full range of construction services.

Sponheuer Bau (Sponheuer Construction)

has been the specialist for Building- and Historical Preservation projects since 1904. Beyond many modern communities, there are buildings that justify their importance as part of an urban collection worthy of preservation or due to a special regional history. The Sponheuer team has extensive experience in renovation, restoration and preservation of historically significant buildings.

“Quality must be self-evident. For all of our team members, this means always doing the right thing -. Even if no one is watching.”

Quality, cost and schedule certainty

play a major role in our solutions. A procedure-oriented system is installed that responds to various needs. Tasks are clearly defined, structured processes described, interactions are identified and documented. Our quality management analysis and strategies are formulated in order to counteract arising problems without need to improvise. The necessary documentation of the processes and measures by the computer and especially through our (Quality Manual) intranet are supported.

Quality assurance by qualified staff

Complex projects require employees who are qualified by education, training, skills and experience. Our employees therefore, regularly attend training courses. In-house seminars and training courses are regularly held at the headquarters. The group also maintains a permanent external employee training program as part of an ongoing platform based on current issues and skills development program. Additionally, the educational value of associations and organizations, in which our Group is member, is also utilized to good advantage.

In addition to acquiring a sound education as a craft or construction engineer, employees continually further qualify for such certificates as SIVV, trained as a safety engineer and much more. They are supported by an extensive library and an intranet information system specialist on all relevant issues.

Through regular internal audits, the implementation and continuation of quality is assured.

With a pre-qualification process, we succeeded to set a uniform, nation-wide standard for proficiency tests according to VOB.

Company · job opportunities

High respect for skilled workmanship

Especially in the construction industry, it comes down to each individual person’s performance in order to be successful. Everything has to fit and sit, every small block must be coordinated. We appreciate people who, in addition to their expertise and dedication, are good team members but can still make correct decisions independently. In rewarding performance, we constantly offer advanced qualification training and offer a job with a secure future.

Whether “old hand” or “beginner,” we always have much to do. Therefore, we are always looking for qualified, dedicated employees and staff – and also welcome unsolicited applications.
