Maidl Tunnelconsultants

What Maidl Tunnelconsultants does

Maidl Tunnelconsultants GmbH & Co. KG (MTC) is a specialized engineering consultancy headquartered in Duisburg, Germany, focused on mechanized tunnel construction. The firm provides end-to-end services across the tunnel project lifecycle: planning (segment design, structural analysis, face pressure calculations, settlement analysis), consulting and construction management, verification/certification, claim management, BIM services, and forensic engineering. MTC serves both infrastructure owners and public authorities (railway authorities, metro operators) and tunnel contractors executing mechanized tunnel boring machine (TBM) projects globally, with reference work in 42 countries.

The company's core proprietary asset is PROCON II, a cloud-based real-time data management and process controlling platform for TBM operations. PROCON II integrates machine data, geotechnical monitoring, BIM models, shift reporting, tool management, segment tracking, and settlement monitoring into a unified software environment with modular components (Dashboards, Shift Reporting, Tool Management, Monitoring, BIM Integration, Mobile, Reporting). The platform's analytics engine draws on digitized know-how from more than 200 reference projects covering 600+ km of tunnel advance, enabling real-time variance comparisons across projects on cost, schedule, and safety dimensions.

MTC operates through three German offices (Duisburg, Munich, Bochum) with a leadership team including managing directors Dr.-Ing. Ulrich Maidl and ir. Jeroen de Leeuw, alongside scientific advisors Prof. Bernhard Maidl and Prof. Markus Thewes. Revenue is generated primarily through professional service fees for project-based engineering engagements, with PROCON II offered as a modular software platform (clients can purchase only required modules). Since 2025, MTC has been part of the Dutch engineering group Witteveen+Bos (over 1,500 engineers), supporting its international scaling and integration into a broader infrastructure services platform.

Functional benefit

Brands

• PROCON II: A cloud-based real-time data management system for technical controlling of mechanized tunnel drives, developed by Maidl Tunnelconsultants for process optimization and monitoring.

Products and services

• PROCON II PROCON II is a proprietary cloud-based real-time data management and process controlling platform for mechanized tunnel boring machine (TBM) operations. It acquires, analyzes, and visualizes all available process data from TBM machines including machine data, shift reporting, tool management, monitoring data, BIM models, and segment tracking. The platform is offered modularly so clients can purchase only the modules required for their project, with MTC providing complete configuration and data hosting from a single supplier.
• Design and Planning Services Specialized engineering services for tunnel projects covering segment design and structural analysis using 3D CAD software, face pressure calculations for TBM excavation verified using the observational method per DIN 1054, and numerical settlement calculations for urban tunneling projects. Designed for infrastructure owners and contractors planning new tunnel construction.
• Construction Management and Consulting Expert support during tunnel site implementation and online back office support including process analysis, risk assessment, and optimization of excavation based on experience from over 200 reference projects. Provided for contractors executing mechanized tunnel boring projects.
• Verification Services Certified verifier (anerkannter Prüfer) and expert (Sachverständiger) inspection services examining tunnel projects for process technology and structural stability, including dispute evaluation and technical design assessment. MTC holds regulatory-recognized credentials for certification that enable independent expert verification of structural safety.
• Claim Management Real-time target versus actual comparison on costs, schedule, and safety basis for optimizing construction processes and clarifying risk distribution among project partners. Provided to contractors and infrastructure owners to manage contractual risks from ground condition disputes and cost overruns.
• Forensic Engineering Localization and root cause analysis of failures using PROCON II for deterministic and statistical analysis, including FMEA (Failure Mode and Effects Analysis) for key tunneling processes. Provided for insurance companies, contractors, and project owners requiring expert damage assessment, failure analysis, and dispute resolution support.
