M&A: Drees & Sommer takes over the Thurm & Dinges planning company

Peter Tzeschlock, Chairman of the Executive Board at Drees & Sommer

The consulting and project management company has taken over the Stuttgart BSE planning company Thurm & Dinges. The parties agreed not to disclose the price. The acquisition further expands Drees & Sommer’s engineering capacity both in terms of personnel and expertise. Thurm & Dinges will be fully integrated into the company. All 37 employees of the company at the Stuttgart and Basel offices will be retained. This acquisition is Drees & Sommer’s response to the market: An increasing number of customers are awarding contracts for general construction management including general technical planning, which comprises building services equipment, energy design, facade technology, building physics, facility management and structural engineering.


In recent years, Drees & Sommer has increasingly moved from project management and individual planning services to becoming general construction manager (GCM) and general technical planner. The reason: The steady increase in demand for holistic consulting and planning services. According to the company, general technical planning – in particular the collaborative consulting and planning of building services equipment (BSE), including energy design, facade technology, building physics, facility management and structural engineering – will experience increasingly strong demand in conjunction with other services. The company already employs 50 building services equipment planners who take planning into their own hands. “We can no longer meet increasing demand through organic growth – particularly when it comes to engineering with a focus on building services equipment,” said Peter Tzeschlock, Chairman of the Executive Board, explaining the takeover. Although the company was able to hire an additional 230 engineers in 2013, the skills shortage was particularly acute in the area of BSE. The job market is almost devoid of top professionals in this field. “To ensure that we remain a strong partner for our customers in the field of engineering, we have – in Thurm & Dinges – found a BSE specialist planning company that ideally complements our team with extensive expertise and experience,” says Professor Michael Bauer, Partner and Managing Director of Drees & Sommer and expert in the field of engineering.

Thurm & Dinges and Drees & Sommer are are no strangers to each other: They have already collaborated on numerous projects in Germany and Switzerland, including projects such as the Karlsruhe Messe (trade fair) and Roche Building 1 in Basel. Thurm & Dinges is a leading engineering firm in the field of building services equipment. Founded in 1971 as a consultancy for supply engineering and electrical engineering, over the years the Stuttgart-based company evolved into a specialist for building services equipment. In addition to its Stuttgart office, the engineering firm maintains a second office in Basel. The consultancy and service provider generated sales of EUR 3.6 million with its 37 staff in 2013.


“Our company offers many years of experience in BSE planning and has established a reputation as an expert for a smooth and goal-oriented planning and construction process. We can look back on numerous successfully realized projects. And we will remain a reliable partner to our customers – now under the strong Drees & Sommer brand,” says Veit Thurm, former Managing Director of Thurm & Dinges. “The takeover offers us the opportunity to work on bigger projects. We look forward to exciting challenges, many new projects and over 1,770 colleagues.” Veit Thurm and Achim Hausch jointly managed the operations of the planning company. Both will also assume leadership roles at Drees & Sommer.


The organizational merger will be followed by spatial consolidation: “This will ensure that all new employees are not only optimally integrated into project work, but also into the everyday work environment,” says Peter Tzeschlock.
