It was the second major meeting of the BIM2WATER competence initiative, which pools the experience and knowledge of 10 medium-sized planning offices on the BIM methodology for digital planning, construction and operation in water management. DAHLEM is one of the cooperation partners supporting stakeholders in the water industry with the BIM methodology in a targeted and demand-optimized way. The background of the coalition is that the general and individual requirements of the BIM methodology are not yet at a level that allows an easy start. Before corresponding activities could be undertaken and while still in the introduction phase, the possibilities and prerequisites must be competently recorded and evaluated by the respective participants. Afterwards, an individual action strategy must be elaborated. For this purpose, among other things, basic building blocks for a uniform and thus economical approach are developed for all participants. Within the scope of the BIM implementation, the client is supported in the partially necessary adaptation of these basic modules to individual needs and prerequisites.
