ABOUT US

At ADNBA Planungsgesellschaft UG we've been designing and modelling using BIM since 2016. Ranging from small-scale to large-scale projects across a multitude of project types, we have sucessfully implemented BIM on all project phases.

We complement our experience with consistent personnel training and in-house developed automation technologies. This has allowed us to develop a flexible yet standardized workflow, that is capable of delivering projects in multiple languages and that can be quickly adapted to any project needs.

 

BIM AT A GLANCE

By implementing BIM into our workflow we were able to improve collaboration between the different disciplines involved in the design process. It also helped us reduce the risk of potential clashes between building elements. With BIM, our designers benefit from all of the different inputs compiled and shared in a centralized model, in a way that 2D software isn’t able to capture. This allows us to offer services of consistently high quality and a quick handover time.

 

The BIM model is used for:

  • design, drafting and deliverables
  • 3D coordination & cross-discipline coordination
  • visual and automated quality control workflows
  • quantity scheduling
  • cost planning and estimation
 
 
 
 
Why should the client request integrated BIM modelling?
  • better decision-making basis in the planning and construction process
  • 3D visualizations and virtual tours in the BIM model
  • fast and accurate cost estimation at any planning phase
  • better project coordination through collision-free planning
  • the reduction of non-budgeted changes 
  • the reduction of the total project duration
  • a basis for efficient facility management

 

 

A CENTRALIZED DATA MODEL

The BIM model functions as a virtually-constructed building, and can be seen as a centalized database that holds all the geometry and all the aggregate information in a project.

This allows all project disciplines to work together and coordinate in real-time on the same model. Because project teams always work with the latest changes in a project, this helps coordinate clashes and reduce project handover. By further using BIM as an issue tracking platform, our teams can better organize and resolve the various problems that can arise during design.

The BIM model is more than just geometry. The information attached to each element is a key part in BIM, as it offers a deep understanding about the workings of each project. By coupling this information with the virtual representations of actual building elements, the model can be used for a wide variety of purposes including construction documentation, quantity takeoffs, project management, on-site construction assistance, fabrication and facility management.

 

THE ARCHITECTURAL MODEL

In a BIM model, all elements receive classification codes, which are always synchronized with the associated descriptions and values that appear in quantity takeoffs. This eliminates human error associated with manually annotating, tagging and quantifying elements. This classification is also reflected in the visualization of the model, for example the plasterboard layers are represented with different colors depending on the type of board, which makes it possible to visually check the model for consistency.

 

The model we create is a faithful representation of the systems that are actually built. If the layers of a system vary, this is reflected in both the model and the quantity takeoffs.

Above, vertical returns of the XPS thermal insulation from the terrace are modelled according to design specifications.

The process of modelling the facade allows us to use element classification and labeling schemes on all the components that are part of it. This ensures that element labels and quantities are always accurate as the project changes over time.

 

 

THE MEP MODEL

 

To better complement our design process, we have established an in-house MEP design division in 2018. This allows us to coordinate and deliver projects in a standardized manner across all disciplines.

BIM in MEP planning and design begins by directly adopting the architects' BIM models. This is followed by a model-based calculation and BIM modelling of the technical equipment. The use of BIM in MEP speeds up the design process significantly, reducing repetition and the amount of time required for design review. In addition, BIM software automatically calculates quantity takeoffs. This way, engineers can focus on designing the best solution without dedicating time to tedious and repetitive tasks.

 

 

 

 

 

BIM modelling allows for real-time display of the MEP model directly on architectural and structural sheets. This ensures that any changes done to either model are immediately reflected on all sheets in the project, eliminating human error associated with placing 2D coordination drawings, and ensuring that architectural modelling is always based on up-to-date MEP designs.

 

 

QUALITY CONTROL & QUANTITY TAKEOFFS

Quantities are extracted directly from the model, in separate Excel files corresponding to each element’s classification type. These are then dynamically linked in a centralizing Excel file, which holds all the data, structured according to bidding requirements. This allows for rapid updating of takeoffs during the evolution of the project.

The BIM workflow allows the visual inspection of elements which generate quantities, ensuring these are always accurate and greatly reducing the risk of errors.

 

CLASH DETECTION

The biggest advantage of BIM-based collaboration between architecture, structural and MEP engineers is what ultimately saves the most costs on the construction site: much better collision control. Possible discrepancies and collisions between the specialist models can be detected after merging these models either rule-based or visually. 

An integrated Architecture + MEP BIM Modelling approach allows us to use Navisworks to test for clashes. By using this workflow, we can consistently identify intersecting elements, therefore greatly reducing potential problems which could arise after project handover.

 

ADVANCED MODELLING

 

We parametrically model windows of any complexity. Our solution allows the individual modelling of each constituent component of the window, which results in extremely detailed and accurate quantities, according to manufacturer specifications.

 

We automatically generate window legends using custom-built scripts, completely eliminating human error from the annotation process. This method allows us to offer a level of detailing above existing market standards.

 

PARAMETRIC DESIGN & AUTOMATION

We design ramps parametrically, which ensures the generation of geometrically correct models. This allows for quick spatial analysis in the Concept Design phase, and correct tracing in the Detailed Design phase.

 

In order to maintain consistency across different models within the same project, we employ a centralized method of classifying elements. This ensures that similar elements always receive the same marks, descriptions and parameters, and schedule correctly when a project is split into multiple models. We achieve this by having all element types and descriptions in a single database, and use custom scripts to update this information across multiple models.
