Reim & Reimers Ingenieure GmbH

What Reim & Reimers Ingenieure GmbH does

Reim & Reimers Ingenieure GmbH is a privately held German engineering consultancy (GmbH) headquartered at Nordenhamer Str. 3 in Bremerhaven, specializing in building technology (Gebäudetechnik) planning. The firm delivers end-to-end TGA (Technische Gebäudeausrüstung) consulting across all six technical building equipment disciplines — sanitary, heating, ventilation, cooling, building automation, and electrical engineering — for building owners and property developers undertaking renovations or new construction of demanding properties in the Bremerhaven area and the broader Bremen Metropolitan Region. Its service process is structured in three phases: initial consulting (including existing-building analysis), planning, and realization with dedicated construction management, positioning the firm as the single-source interface between architecture and technology.

The firm's technical stack centers on Plancal Nova CAD systems for technical building equipment design, supplemented by a thermal building simulation capability that models plant technology and its control systems to minimize energy consumption while maximizing occupant comfort. The company is led by two Managing Directors (Geschäftsführer), Andreas Jongmans and Jens Thaden, with no disclosed external investors, parent company, or subsidiary structure. It maintains a modest digital footprint through its website and social media profiles on Instagram, XING, and Facebook.

The business model is a sales-led, B2B professional services engagement. Revenue is generated through project-based consulting, planning, and construction management contracts on a quote-based pricing model that is not publicly disclosed. The customer base is narrowly defined as building owners and property developers in a single geographic market, and the firm operates without publicly disclosed partnerships, awards, certifications, patents, or funding rounds. No revenue figures, headcount data, or active job postings are available in the source material.
