BIM users day It went to the quality of data exchange, structured 3D data models and a "key factor" user acceptance... It went to the IFC interface, the technique and the certification. But the focus of the event on June 18 in the Wälderhaus in Hamburg the practical State - entirely programmatically - BIM implementation at the planning and construction. How changed BIM the traditional processes in the construction industry? Can existing and model-based approaches be combined? About their individual experiences with BIM reported representatives of construction and technology companies such as for example Wolff & Müller, Hochtief ViCon, Max Bögl, Porr or Hilti, architects and engineers such as Wolfgang Ehlers Ehlers atelier of Prof. Thomas Vietzke associate Zaha Hadid architects, Detlev Gloeckler and Dr. Volker Krieger of fact and experts from software houses such as Graphisoft and DDS. Last but not least the roughly 150 participants of the 10th used BIM users day by buildingSMART the very beautiful architectural part of the hotel - and Congress new building right next to the entrance to the iba and igs 2013 in Hamburg to exchange with industry colleagues and networking. Many roads lead to BIM Before thinking instead of afterwards to heck. That's not only Dr. Matthias Jacob. The technical Managing Director construction for Wolff & Müller in Stuttgart emphasised in Hamburg once more, that BIM is not software, but "An integral planning method, in which incorporate conventional approaches allow." The construction company with its own BIM team now more than five years experience looks back on. This States among them, that the construction and stakeholders the theme BIM and work with clearly structured 3D must first of all understand data models. And exactly functioning based BIM. Stuttgart is therefore consistent. There are there internal training and "Duty projects" for employees, to make the topic really transparent. What is so initially slower and also nerves can cost as well as time and money, pays a definitely at the end. At the latest, if all data accurately and in a model. Jacobs conclusion: "projects are gripping, variant tests go quickly and simply, quantity surveying needs carried only once." This is confirmed by the Kufsteiner Gasteiger of b.i.m.m and Clemens Neubauer, who is responsible BIM management Porr design & engineering for that. Their experience: Although BIM does not always equal BIM is, the focus is still the integral
holistic planning and execution process. And "strictly predefined structures", which take into account both national and international standards are the absolute precondition.
Kai Brandt, Project Director of Hochtief ViCon, know as simple BIM tools used on construction sites. "Only way the structured way of working by BIM in project management." Project and construction manager have neither the time nor the interest to use complex software or CAD." BIM users day see participants of the 10 live, how data on the spot are mobile gathered and transmitted full information with 3-d and photos in a production system. There are online - with information from the planning - for a structured treatment and analysis available. Typical applications are shaft inspections, quality assurance, documentation of construction progress. A possible solution, the digital and very accurate alternative to the reference line, comes from Hilti. Dr. Oliver Geibig and Markus Ziegler explain that "BIM to field" concept of the Kaufering-based group and pointing, like using optical Metrology (robotic total station) media breaks quite practical and elegant can be bypassed on the construction site. The station will work even in time - and cost-saving 1-man operation, the Prism tracking allows up to 400 marking points per day. And the blueprint with BIM is available at the push of a button on the display attributes. BIM works but also on a smaller scale: by the eponymous architecture the program "Cost calculus" Wolfgang Ehlers uses Atelier in Bremerhaven for the model-based determination of costs in the listed portfolio for seven years, a BIM based graphical quantity and cost determination. Thus, he is able to give verifiable cost estimations or calculations, already in the planning. What particularly pleases him: even at building technical attention tests he can provide immediately the corresponding evidence so. Great response Manager was also the basis of seminar by Jakob Przybylo, BIM Obermeyer plan + advised in Munich and the oriented data exchange scenario practice BIM between architects and Haustechnikern, as an example presented by Holger Kreienbrink
