What iMM does

iMM GmbH is a German structural engineering firm headquartered in Bochum, North Rhine-Westphalia, providing strategic structural design (Strategische Tragwerksentwürfe), Building Information Modeling (BIM) planning, and related construction consulting services for demanding large-scale building projects across Germany. The firm traces its lineage to Ingenieurbüro Müller Marl, founded in 1977 by Dipl.-Ing. Rolf Müller, and was re-established as iMM GmbH in 2010 when it adopted 3D-BIM as the foundational methodology for all project work. It is privately held, with Artur Braun M.Sc. listed as Managing Director, and has no disclosed external funding.

The company's core technology is a proprietary 3D-BIM calculation model that enables digital rather than analog structural design, providing load-path verification, load-bearing capacity assessment, reinforcement quantity control, and early identification of potential crack patterns. Its service portfolio spans ten integrated modules: BIM planning, structural engineering (Tragwerksplanung), raw construction planning, excavation pit planning, structural construction management (Fachbauleitung Rohbau), building physics, special foundation engineering, construction consulting, facade planning, and architectural competition support. The firm holds memberships in Verband Beratender Ingenieure VBI, buildingSMART e.V., and Ingenieurkammer NRW.

iMM operates a project-based professional services business model, acquiring clients through enterprise field sales, architect competitions, and project referrals. Its target customer segments include commercial and office real estate developers, hotel and hospitality developers, residential developers, public-sector municipalities, and healthcare clients. Named customers include Siemens, Volksbank Marl, GHOTEL Group, and municipal clients in Düsseldorf and Duisburg, with reference projects across cities including Düsseldorf, Duisburg, Bremen, Neuss, Grevenbroich, Dortmund, Laatzen, and Recklinghausen. The firm maintains a regional geographic focus in North Rhine-Westphalia with selected presence in Bremen.
