BIM ensures efficiency and transparency
Erne Holzbau AG, the general contractor for the project, is using BIM to plan the new structure. The 3D models generated using BIM provide all the necessary information about the individual construction elements, eliminating the need for the time-consuming exchange of planning data.
If an architect moves a wall, for example, this affects the entire structure. Using BIM, such a change is immediately visible to everyone involved. The plumber sees on the computer that lines need to be rerouted, the electrician may have to move the cable ducts. The cost planner is sure to see how these changes affect construction costs.
Erne Holzbau is producing the floor elements and walls for the apartments in Laufenburg in the canton of Aargau. Starting in April 2022, the completed components will be transported to the construction site, where a crane will lift them onto the roof in a matter of minutes.
Lorenz Weissenberger, Construction Management Project Manager at Erne Holzbau, summarizes the advantages of BIM this way: "It simplifies and improves the dialogue among all parties. This results in fewer mistakes and shorter construction time," says the 32-year-old. In the case of LOKwerk, this means 14 months of planning and 21 months of work at the construction site.
Weissenberger underscores the importance of BIM beyond planning and construction. Owners should also provide the property manager with access to the building data, which includes, for example, information about maintenance cycles and which components need to be replaced when. This contributes to the economic efficiency of a property. Even at the end of the life cycle, BIM provides clarity – about which materials can be recycled and more.
