FD InvestConsult GmbH is a privately held German holding company headquartered at Kirchgasse 29 in Öpfingen, dedicated to acquiring, controlling, and developing engineering consultancies that specialize in building technology (Gebäudetechnik), with a particular focus on electrical engineering and supply technology (Versorgungstechnik). The group operates as a portfolio platform providing shared services across finance, IT, human resources, organizational development, and communications to its operating subsidiaries while preserving their individual brand identity and operational autonomy.

The group's operating platform comprises four wholly owned subsidiaries: IBB Burrer & Deuring Ingenieurbüro GmbH (electrical engineering specialist with seven locations and headquarters in Ludwigsburg), Schindler Consult Ingenieurgesellschaft mbH (HVAC, energy, and infrastructure engineering with over 40 years of experience serving domestic and international projects), LP8 TGA GmbH (object supervision and construction management deployed nationwide across all group locations), and TGA PlanungService GmbH (technical building equipment planning, including HLSK, building automation detailing, energy concepts, and BIM consulting). The four firms together operate from 14 locations across major German cities including Berlin, Düsseldorf, Frankfurt, Hamburg, Leipzig, Munich, Stuttgart, Freiburg, Filderstadt, and Ludwigsburg.

The combined service offering spans the full project lifecycle for building technology, from Grundlagenermittlung (requirements definition) and Vor-/Entwurfs-/Genehmigungs-/Ausführungsplanung through construction supervision, schedule management, cost control, and object handover, underpinned by Building Information Modeling (BIM) and CAD methodologies. Revenue is generated through professional engineering services billed on a project-by-project basis, delivered via direct enterprise engagement to clients across commercial and residential infrastructure segments in Germany.

Broad incumbents

• AECOM: Global engineering and infrastructure consulting firm with building engineering practice covering mechanical, electrical, plumbing, and sustainability; competes in the same addressable market for large institutional and commercial building projects that FD InvestConsult's subsidiaries target.
• HOCHTIEF AG: Major German construction group with engineering, design, and facility management divisions delivering building services work; overlaps with FD InvestConsult in building technology planning and supervision, but operates at construction/EPC scale rather than pure consulting.
• WSP Global Inc. Global engineering consultancy with building services and TGA capabilities across European markets; comparable in service line (electrical, HVAC, BIM) and target client base, though operating at vastly larger scale and broader geography.
• Bilfinger SE: German-headquartered engineering and industrial services group with significant TGA consulting and facility engineering capabilities across Europe; overlaps with FD InvestConsult's electrical and supply engineering services but at much broader scale and different delivery model.
• Arcadis NV: Dutch-headquartered global design and engineering consultancy with substantial building services engineering practice in Germany and Europe; comparable in core competencies (electrical, mechanical, sustainability consulting for buildings) but at scale and geographic footprint exceeding FD InvestConsult.

Direct peers

• ZWP Ingenieur-AG: German TGA engineering consultancy providing planning and supervision across HVAC, electrical, and building automation for commercial and institutional projects; directly comparable service mix and customer segments to FD InvestConsult's subsidiaries (TGA PS, ibb, scon).
• Drees & Sommer SE: Large German engineering, consulting, and project management firm with strong building services and TGA practice; comparable in service offering and German market focus, but at significantly larger scale and broader scope (FM, sustainability, real estate).
• Ingenieurbüro Dipl.-Ing. H. Vössing GmbH: German engineering consultancy providing infrastructure, transportation, and building services engineering; comparable as a mid-sized German engineering firm with multi-office footprint and similar consulting/servicing model.
