Our Bachner team shows the full range of its skills

The new building at the main plant required nearly our entire portfolio of services. This is why our technical departments, managed by our site managers David Pulz and Udo Polak, work closely together to ensure that the coordination between them is as straightforward as possible.
Our services are also fundamentally important for the other trades. For example, we are responsible for supplying the construction site with electricity. Due to the scale of the project, this requires 65 distributors, which we are providing for the entire construction period. To ensure that the body construction facility is also supplied with electricity later on, our team installed a medium-voltage switchgear with 28 bays. Six focal point stations (F-stations), each with 1,600 kVA, then transform the medium voltage to the low-voltage level. A further F-station is used for the photovoltaic system with an output of 384 kWp. The photovoltaic system itself will be installed by our Volthaus team in the summer.

The 3-story building also required elevators, which our Bachner team handled as well. Two of the four elevators are passenger elevators, while the other two are freight elevators with a capacity of twelve metric tons each. For the freight elevators, we were also responsible for planning the two electrical switching distributors.
The machines that make production possible in the first place are at the heart of every production plant. The Bachner Group has also been contracted to provide the power connections, data supply, and machine grounding. This requires precise fine-tuning, both within our team and with other trades, to ensure that we always adhere to the BMW Group’s lean construction schedule. The machines have different outputs, so the colleagues need to coordinate precisely what is required at each particular location.
“Here at the BMW Group, we work in two shifts for the machine connections,” says Aldehoff. “During the day, work is done outside the plant. At night, the cables are pulled through the plant. Our site manager Alexander Hierl is responsible for coordinating with the other trades for the day and night shifts—he does a really excellent job.”

Under the leadership of Christian Daimer and Sebastian Frank, and directed by our site manager Philipp Kobsa, our colleagues for control system technology are also involved in the project for the BMW Group. A total of 14 substations are being built here, all required for a wide variety of tasks. Six of the substations alone are required for the roof ventilation systems, three for smoke extraction, and two serve as data collectors for air conditioning units, door air curtains, and two small ventilation systems. One substation each is also required for the central cooling and heating system, the meter cabinet, and the well water.
Another special feature of the control system technology is that the ventilation systems are used to cool the production robots during winter. The implementation of warm smoke extraction is another important milestone that is underway in the two building complexes 36.0 and 36.2.

Due to its sheer size alone, the new body construction facility for the BMW Group is a challenging project. “To ensure that we can meet the planned completion date, all trades in our Bachner Group are working hand-in-hand. This cooperation is part of what defines us as a company,” says Daimer. Aldehoff shares this view and adds, “I am really proud of our teamwork.”
