Debeka Koblenz, Germany
Comprehensive BIM Modelling & Coordination for a 25,000 m² Office Development
A large-scale office building project in the heart of Koblenz, Germany, focused on the comprehensive modelling, optimization, and coordination of engineering systems. The project required advanced BIM workflows, multidisciplinary coordination, and construction-ready documentation to support one of Germany's leading insurance groups.

Debeka Group is one of Germany’s largest insurance organizations and one of the country's leading financial institutions. The new Debeka Koblenz headquarters was designed as a modern 15-storey office building providing approximately 25,000 m² of workspace for employees.
The project required the optimization of engineering systems according to updated architectural solutions, full multidisciplinary coordination, and the production of Stage 5 construction documentation to support efficient project delivery.
[ Challenges ]
Design Optimization During Ongoing Development
The project was received at Stage 3 while architectural solutions continued to evolve. Engineering systems had to be continuously reviewed and adapted to align with the latest design updates without compromising coordination quality.
- Architectural design updates
- Engineering solution optimization
- Continuous model revisions
- Design validation
- Coordination adjustments
Without a structured BIM workflow, ongoing design changes could create inconsistencies between engineering models and construction documentation.
- Rework risks
- Documentation revisions
- Coordination delays
- Model inconsistencies
Large-Scale MEP Coordination
The 15-storey office building required continuous coordination between engineering, architectural, and structural disciplines. Multiple systems needed to coexist efficiently within the same building environment.
- Water supply systems
- Sewage systems
- Architectural coordination
- Structural coordination
- BIM integration
Managing coordination at this scale required ongoing validation and communication to prevent conflicts and maintain project progress.
- Routing conflicts
- Spatial limitations
- Interdisciplinary dependencies
- Increased coordination complexity
Stage 5 Documentation Accuracy
The project required highly detailed Stage 5 construction drawings generated from coordinated BIM models. Every engineering decision had to be reflected accurately within the final deliverables.
- Construction drawings
- Fabrication information
- BIM documentation
- Engineering schedules
- Technical support
Maintaining synchronization between BIM models and issued documentation was critical for construction readiness.
- Documentation control
- Quality assurance
- Model synchronization
- Construction validation
[ Solutions ]
BIM-BASED DESIGN OPTIMIZATION
To accommodate evolving architectural requirements, all engineering systems were continuously reviewed and optimized throughout project development. The BIM environment allowed the team to evaluate changes quickly and ensure engineering solutions remained coordinated with the latest design information.
- KEY ACTIONS
INTEGRATED COORDINATION WORKFLOW
Water supply and sewage systems were modelled to LOD 300 and coordinated with architectural and structural models using a centralized BIM process. Continuous coordination reviews helped identify potential conflicts before construction documentation was issued.
- KEY ACTIONS
Technical support
Stage 5 construction documentation was produced from coordinated BIM models, providing Debeka Group with optimized engineering systems ready for construction and future project planning.
- KEY DELIVERABLES
[ Scope of Work ]
The initial scope of work focused on engineering optimisation and BIM coordination
The project required the optimisation of engineering systems, coordination with architectural and structural disciplines, and the delivery of Stage 5 construction documentation for a 25,000 m² office development in Germany.
DESIGN OPTIMISATION OF ENGINEERING SYSTEMS
Review and optimisation of existing engineering solutions to align with the latest architectural design.
LOD 300 BIM MODELLING
• Water Supply Systems • Sewage Systems • Construction-ready engineering layouts
BIM COORDINATION & CLASH DETECTION
Coordination of engineering systems with architectural and structural models using Navisworks and BIM workflows.
STAGE 5 CONSTRUCTION DOCUMENTATION
Production of detailed Stage 5 construction drawings and technical support throughout project delivery.
[ Delivery Process ]
BIM Review & Optimization Planning
The project began with a comprehensive review of the Stage 3 information received from MEP contractors. Existing engineering solutions were assessed against the latest architectural requirements to identify optimization opportunities and establish a clear BIM coordination strategy.
- So we started with the key project requirements:
-
Review Stage 3 project information
-
Assess engineering solutions
-
Define BIM coordination strategy
- Following approval, a project-specific BIM workflow was established, defining:
-
BIM standards
-
Coordination priorities
-
Documentation requirements
BIM Modelling & Coordination
After defining the scope of work and project objectives, we began modelling water supply and sewage systems to LOD 300 in Autodesk Revit while continuously coordinating them with architectural and structural disciplines.
- Key efficiencies included:
-
LOD 300 BIM modelling
-
Water supply systems coordination
-
Sewage systems coordination
This ensured consistent engineering development, reduced coordination risks, and improved collaboration between all project disciplines.
Clash Detection & Project Delivery
Since multiple disciplines were working simultaneously within the same BIM environment, we used Navisworks and BIM360 to continuously monitor coordination and identify potential conflicts before construction documentation was issued.
-
Clash detection reviews
-
Coordination meetings
-
Conflict resolution
Rather than reacting to issues during construction, the team resolved conflicts early, resulting in a coordinated BIM model and construction-ready project delivery.
[ Results ]
The coordinated BIM workflow improved engineering accuracy, reduced coordination risks, and delivered a fully optimized model ready for construction.
