It was required that<\/p>\n<p>there was to be full operation in the hall during the entire construction period,<\/p>\n<p>which meant very little space for construction equipment. A crane<\/p>\n<p>who constantly passed over the workplace also asked very much<\/p>\n<p>strict safety requirements. The shaft is also placed all the way in<\/p>\n<p>to a heavily loaded foundation at a depth of 2.2 meters below<\/p>\n<p>floor level.
