Digital Planning in timber construction
Timber construction and digital planning processes have a dream team for years. In timber construction, 3D planning has been the standard for decades. The perfection of the components and processes is impressive.
Wooden buildings can be prefabricated and are ready after a short construction time. This is one of the great advantages of timber construction. To make this possible, construction projects are planned down to the last detail before construction begins. A so-called digital twin, including all information on the construction project, is produced.
In the 3D model of the "timeout" staff restaurant at the Aarau Cantonal Hospital, all the information from various specialist planners come together.
The timber construction planning as a principle
In conventional solid construction with a low prefabrication level, planning often continues into the execution phase. Adjustment work on the construction site and slotting work for electrical and plumbing installations are part of the process. This is different with timber construction projects: It needs a clear cut between planning and execution. The cable routing and all installations are planned in advance. For the the building owner, this means that by the end of SIA phase 51, they have to make the definitive decisions about the placement of installations such as ceiling spots, junction boxes and wall boxes. They are already installed in the wooden elements in the manufacturing plant.
A wood construction-suitable planning is completed prior to the start of construction. Between planning and execution there is a design freeze.
Research projects for planning in timber construction
For the further development of timber construction planning, we are involved in research and development projects with universities and associations.
LeanWood research project with the Lucerne University
Research project DeepWood with the Lucerne University of Applied Sciences and Arts and the Bern University of Applied Sciences
Network project "TGA-Timber" of the Wood Research Austria
The performance matrix provides guidance on what timber construction-ready planning looks like. All stakeholders provide the right information at the right time. This is the only way to complete planning before construction starts. This is necessary for the prefabrication of the timber components.

For timber construction planning, we usually use the Cadwork software. The example with the prefabricated wall element and the facade elements shows that all information is included in the plan.
