Schlieren ZH – Building work on the Spital Limmattal is expected to finish at the end of 2018. The construction site was recently visited by a number of international experts, who have a particular interest in the process of building information modelling (BIM) being applied at the hospital.
An article on the baublatt website reported that the experts travelled in from various European countries as well as China, Japan and South Korea. Building information modelling (BIM) is the digital representation of physical and functional characteristics of a facility. This already comes into play in the planning stages and is accessible to all involved in the project, so they can immediately see any changes to plans.
BIM is also used to monitor construction progress. One way in which it manifests itself is through codes attached to windows in individual rooms. In the article, Martin Peiner, BIM Manager of general contractor Losinger Marazzi AG, explains: “The QR codes are created with Finalcad. The room and its characteristics are automatically recognised when the code is scanned. In combination with Revit, this means it can be precisely tracked who completed what work in each room.” Alongside building progress, BIM also records material deliveries.
Furthermore, BIM serves as a basis for virtual reality representations. For example, many different pipes will be installed in the central ventilation. A 3D representation of the room can be opened on a tablet on which the different pipes can be identified through colour coding. In future, BIM will also be used in building management. This is another reason why the international experts travelled to Schlieren to learn more about the many possibilities presented by this technology.
