Method for operating a construction site device and construction site device

A method for vertical transportation of people and/or material in a building during a construction phase of the building, the method comprising the steps of:

• arranging a climbing formwork device in a currently uppermost region of the building to concrete at least part of a building core of the building, the climbing formwork device including a climbing formwork platform and being adapted to be hoisted in steps;
• installing an elevator system in a first elevator shaft of the building, the elevator system adapted to adjust to an increasing building height and having an elevator car, wherein a conveying height of the elevator system is intermittently adjusted to a current building height by hoisting a mechanical platform including an elevator drive machine to a higher level and fixing the mechanical platform in the first elevator shaft, and wherein at least two currently uppermost floors of the building cannot be reached by the elevator car after the conveying height is adjusted;
• installing a construction elevator temporarily in a second elevator shaft in the currently uppermost region of the building and attaching the construction elevator to the climbing formwork platform, wherein the construction elevator includes a construction elevator frame, a construction elevator car vertically movable in the construction elevator frame, and at least two access openings arranged in the construction elevator frame and corresponding to adjacent shaft door clearances in a shaft wall of the second elevator shaft;
• transporting people and/or material by the elevator system to a first floor in the building associated with one of the at least two access openings;
• and
• transporting the people and/or material from the first floor to a higher second floor in the currently uppermost region of the building or to the climbing formwork platform using the construction elevator.
