Transportation - site logistic119/11/201212Organizational questions: Do structural elements have to be stored on the side?(Avoid if possible!) Is it possible to lift the elements directly from the trailerto their final place or a part of the structure have to beassembled on the ground before lifting? How can the shipments enter and leave the site? (Driveroutes in case of a long-vehicle) What is to be considered as main equipment?Vidovszky – BUTE/BME-Faculty of Architecture – Department of Construction Technology and Management9/11/20126
