What Ludewig + Bock Ingenieure Partnerschaft mbB does

Ludewig + Bock Ingenieure Partnerschaft mbB is a German engineering consultancy (Partnerschaft mbB) specializing in construction project management and oversight for large-scale public infrastructure projects, particularly bridges, tunnels, and highway systems. The firm is co-founded and entirely owned by three partners — Jochen Ludewig, André Bock, and Klaus Mischke — who together bring 70+ years of combined experience from senior roles at BGS Ingenieure, Grontmij, and Sweco. With 8 employees, the firm operates an operational headquarters in Frankfurt am Main (House of Logistics & Mobility) and a registered seat in Hainburg, delivering services across German federal states including Hessen, Nordrhein-Westfalen, and Bayern.

The firm's service portfolio spans four competency fields — Hochbau (structural engineering), Ingenieurbauwerke (engineering structures), Verkehrsanlagen (traffic facilities), and Projektmanagement (project management) — delivered through specialized offerings including Projektstrukturierung (project structuring), Bauoberleitung/Bauüberwachung (construction supervision), Vertrags- und Nachtragsmanagement (contract and change order management), Independent Engineer services for PPP/V-Modell projects, and technical consulting/troubleshooting. The firm explicitly positions itself as a 'troubleshooter' for complex or distressed projects, with documented engagements on the €3B A3 Steigerwaldautobahn PPP, €1.2B A94 Isentalautobahn PPP, €620M A40 Rheinbrücke, €225M Salzbachtalbrücke A66 (post-2021 collapse), and €456M B10 Rosensteintunnel Stuttgart.

The firm generates revenue exclusively through professional services fees on project-based engagements with public-sector clients, sourced via direct engagement and public procurement. Named clients include Autobahn GmbH des Bundes, DEGES, Landesbetrieb Straßenbau NRW, Wasserstraßen-Neubauamt Datteln, and Landeshauptstadt Stuttgart Tiefbauamt. Go-to-market is partner-led via professional networks (VBI, VSVI, Ingenieurkammer Hessen) with minimal digital marketing. Revenue is not publicly disclosed; the firm is privately held with no external investment.

Broad incumbents

• WSP Germany: International engineering professional services firm with German infrastructure capability across bridges, tunnels, and highways. Competes for similar public-infrastructure mandates but operates as a much larger global platform.
• Arcadis Germany: Global design and consultancy firm with a German infrastructure practice covering highways, bridges, and PPP advisory. Overlaps with L+B in transport infrastructure consulting but offers a far wider portfolio of services.
• Sweco GmbH: Largest Nordic-headquartered engineering consultancy in Germany, formerly employing all three L+B founders. Offers the full lifecycle of infrastructure engineering services and competes broadly for the same German public mandates, but at much greater scale.
• Drees & Sommer SE: German-headquartered engineering and consulting firm with infrastructure, building, and project-management services. Comparable in advisory and PM scope but with broader sector coverage and significantly larger headcount.

Direct peers

• Vössing Ingenieure GmbH: German engineering consultancy delivering planning, design, and construction supervision for major transport and infrastructure projects. Direct competitor in the same highway, bridge, and tunnel engineering niche with overlapping public clients.
• Ingenieurbüro Grassl GmbH: Specialist German engineering consultancy focused on bridge, structural, and transport infrastructure design. Closely comparable technical specialization and public-sector client base to L+B, though larger in headcount.
• KREBS+KIEFER Ingenieure GmbH: German engineering consultancy offering planning, structural design, and project management for infrastructure including bridges, tunnels, and highways. Directly comparable service portfolio and public-sector client base to L+B, though at significantly larger scale.
