Building Information Modeling

Planning

A digital model of the building serves as the basis for BIM-based planning of every project. Spatial and building component qualities such as materials used and fire- and noise-protection properties are recorded in the first stage of this 3D model (BIM 3D).

During two-dimensional planning, this consistent foundation – created at AUKETT + HEESE in Autodesk Revit – guarantees end-to-end consistency across all floor, section, and elevation drawings all the way to detailed plans.

Our planning process also includes the depiction of different building versions as 3D models to enable a standardised approach during all service phases. This makes it possible to analyse building cubatures in concept studies. In the detailed design planning phase, parts of buildings and groups of rooms are made available to the developers and the planning team as a basis for decision-making.

Collaboration

As architects, we take a holistic view of the planning process, resulting in careful coordination and close collaboration with all involved technical planners. In recent years, we have planned numerous open and closed BIM projects.

In open BIM projects, organisation occurs across different platforms and softwares. This means every technical planner is able to use the data from other disciplines as the basis for their plans. In the project to renovate Das Center at Potsdamer Platz, the TGA models were created on the basis of architectural models.

Closed BIM projects offer additional opportunities to optimize the planning process because all technical planners work with the same planning software. In the EDGE East Side high-rise project, the support structure model was linked to the architectural model and directly displayed there thanks to Autodesk’s BIM360 cloud solution. As a result, only the planner responsible for the supporting structure had to adjust the shell elements – their changes were automatically updated for everyone else involved. We rely on comprehensive planning in which technical solutions are developed in cooperation with other departments in order to improve the planning process.

Material Schedule

We use the planning model as the basis for creating lists of rooms and materials. These lists are linked to the model and can be read out automatically.

This means that changes to the plans are automatically updated in the lists and vice versa – additions made to the lists are depicted in the characteristics of the respective elements in the model. Furthermore, all requirements from clients and user requests can be exported from the 3D model in tabular form. When preparing documentation for technical planners and contractors, component lists like window and door lists are essential.

Building information modelling guarantees end-to-end consistency in terms of plans, lists and other documents, which in turn makes it possible to optimally integrate information on component requirements and characteristics into the relevant planning.

Simulations

In unserem Projekt KaDeWe halfen uns Simulationen anhand des dreidimensionalen Planungsmodells bei Prüfungen der geplanten Bauwerke. Das Kaufhaus wurde abschnittsweise im laufendem Betrieb umgebaut , was eine zusätzliche Planung von temporären Maßnahmen für Baulogistik und Gebäudenutzung erforderlich machte. Mithilfe des 3D-Modells konnte der gesamte zehnphasige Bauablauf dreidimensional vor Projektbeginn simuliert und mit allen Projektbeteiligten abgestimmt werden.

Eine präzise Gebäudeoptimierung kann außerdem durch eine Tageslicht-Simulation erfolgen. Sie hilft beispielsweise bei der Planung von Arbeitsplätzen. Darüber hinaus lassen sich auch Schallschutzwerte, Temperatur und Luftströmungen simulieren, um die Behaglichkeit im Gebäudeinneren zu optimieren.

Model preparation for facility management

Compared to the operational phase, the planning and construction phases are just a short time in the lifecycle of a building. This is why it is especially important to include information about operation and products into the 3D model – and thereby into the planning and implementation processes – early on. Building information modelling makes it possible to integrate this information and make changes to plans in a timely manner in order to satisfy building operators.

Creation of an “as-built model” using surveyor data is often the basis for building operations. At AUKETT + HEESE, we can coordinate this process from offer preparation all the way to the final performance check.

Quantity Takeoff and Cost Assessment

At AUKETT + HEESE, we use model-based quantity take-offs. The results can be easily exported in tabular form. To calculate costs, we use an interface between the architectural model and the software ORCA AVA. This allows us to read out components directly from the 3D model and assign cost groups to them, ensuring accurate planning and reliable cost calculations for our projects.

BIM Coordination

In addition to model-based planning work, AUKETT + HEESE also offers overall BIM coordination. We can help you with BIM project organisation – from defining strategic goals to conducting suitability tests of planning firms all the way to creating concrete project specifications and implementation during the planning and execution phases.

AUKETT + HEESE will define the software environment and carry out all the required test phases with model exchange to ensure that the project runs smoothly from start to finish. On this basis, our overall BIM coordinators combine the individual technical planning models to create an overall coordination model and carry out collision checks. We then hold coordination meetings where the results of these checks are distributed to the responsible planners, whose task tracking and documentation at the end of the planning phase are used to create a collision-free overall model.
