ICL Engineering Consult

What ICL Engineering Consult does

ICL Ingenieur Consult GmbH is a German engineering consulting firm headquartered in Leipzig, founded in 1990. The company provides consulting, planning, and management services across three horizontal business fields: infrastructure (roads, railways, waterways, environmental/energy projects), engineering structures (bridges, tunnels, hydraulic and port facilities, special structures), and urban planning and buildings (city planning, industrial buildings, commercial and institutional facilities). It serves government entities, municipalities, and industrial clients through competitive public tenders and direct enterprise engagements, with project-based, multi-year contracts covering the full lifecycle from feasibility study through commissioning.

The firm's core technology is Building Information Modeling (BIM), used as a cross-cutting methodology to integrate all interdisciplinary trades into a single digital building model for planning, construction, and facility operations. BIM is positioned as both a deliverable (modeling, coordination, CDE administration) and an internal collaboration framework ("Smart Grid") linking the firm's eight German offices. The company also operates through a group structure with four operating subsidiaries (ICL Rail GmbH, Körting Ingenieure GmbH, wpm-ICL GmbH, BST Railkonzept GmbH) that specialize in rail engineering, structural engineering, and project management.

ICL generates revenue through professional services fees on long-cycle infrastructure and building projects, with reference portfolio exceeding EUR 2 billion in cumulative individual project investment volume over 35 years. Marquee projects include the Waldschlösschenbrücke Dresden, BMW Werk Leipzig, Porsche paint shop Leipzig, Universitätsklinikum Leipzig, HafenCity Hamburg, and the cross-border O2 Oderbrücken railway bridge with DB Netz AG. The firm has no public listing, no external investors, and is led by managing directors Jan Czerwinski and Dr. Mark Husmann.
