Digital formwork planning "to go"

The construction company Schmack Bau GmbH successfully used the new construction of a coffee roasting plant with coffee house as an introduction to the paperless construction site (BIM2Field).

Tradition meets modernity: with almost 100 years of company history, the Rehorik company in Regensburg is an institution when it comes to coffee and delicatessen. The construction of the new site by Schmack Bau GmbH was nevertheless carried out in a forward-looking manner using the latest methods that the construction industry has to offer. In collaboration with Doka, the construction company handled the formwork planning completely digitally in BIM. What's more, in keeping with the motto "To go, please!", 3D models (BIM2Field) were also used for the first time on the construction site to coordinate the formwork sequences in a paperless process.

A lever for more productivity

With the increasing digitalisation of the construction industry, virtual formwork planning in BIM (Building Information Modelling) is also being used more and more widely. However, the fact that virtual models are also finding their way onto construction sites and replacing traditional plans there - known as BIM2Field - is still the exception. However, Luitpold Gerl from Schmack Bau GmbH in Regensburg, Upper Palatinate, has always moved with the times and is open to the opportunities that digital change has to offer in terms of increasing productivity: "Anything that helps us to complete our projects more efficiently is of interest to us. Digital formwork planning is definitely a promising lever here."

The construction of a new coffee roasting plant with warehouse and adjoining coffee house provided him and his team with an ideal pilot project to take the step towards a paperless construction site together with Doka. It was ideal because the building project, for all its architectural sophistication, was largely standard in terms of formwork technology and therefore "manageable" for everyone involved in the project. Above all, the construction site team was able to rely on their expertise when shuttering and striking the formwork and test the additional benefits of working with 3D models using familiar, well-established processes.

Virtual models "to go"

Doka's formwork technicians took on the BIM planning for the project. Based on a 3D building model created with the Autodesk Revit© planning software, the optimum Doka formwork solution was modelled in just a few steps using the DokaCAD for Revit plugin. The walls were planned using Framax Xlife plus panelised formwork in combination with Frami Xlife. Dokaflex girder slab formwork was used for the slab. The circular columns, which were also included in the design, were realised with RS column formwork. The shoring for the over 7 m high slabs with beams in the coffee house area proved to be comparatively challenging. This shoring was realised with Staxo 100 towers. For the more than 30 m long beams, it had to be ensured that they were constructed in a single concreting section for structural reasons. This requirement was also incorporated into the digital formwork planning.

A total of 20 cycles were planned for the formwork work. A 3D formwork model was created for each cycle and transmitted to the customer via a CDE (Common Data Environment, in this case BIM360) in open IFC format. From there, the virtual models were sent "to go" to the tablets of those responsible on the construction site.

Always everything in view

In contrast to working with paper plans, the model-based approach made it possible to view the structure and formwork from any perspective and down to the smallest detail, to create horizontal and vertical sections if necessary and to show or hide certain plan components as required. This clarity not only ensured in advance that the formwork processes could be planned particularly efficiently, i.e. with optimised use of resources and materials. During the work itself, target/actual comparisons with the "digital twin" also helped to check the construction of the formwork and shoring just-in-time, quickly recognise any deviations and rectify them without losing time.

To be continued

The construction project has now been completed and the coffee is flowing at the new Rehorik site. For Luitpold Gerl and his team, the start of the paperless construction site was a complete success: "We always had the virtual plans to hand and immediately got to grips with them. Working with the 3D model was very clear and therefore easier than with traditional plans. We were particularly amazed at how close the virtual view was to the real thing. The term digital twin sums it up very well. And by comparing it with the model, we knew at a glance: Everything fits!" Gerl definitely sees a continuation of the model-based approach for future projects - without any "paperwork".

The construction project has now been completed and the coffee house has opened. A successful pilot project for the paperless construction site for Schmack Bau GmbH.
