The method and the arrangement described are preferred for midrise buildings up to 20 floors with a group of two elevators. In such a sectional or staged installation method and arrangement, the elevator is installed in stages for construction time use CTU. The installation can start when the building has reached an agreed height of about ½ of the final height of the building. Then, a CTU elevator can be installed in the bottom section and simultaneously the raising of the building can continue above the operating CTU elevator.
The described method and arrangement enable the elevator installation when the building is raising up, already before a hoistway ceiling is closed and corresponding lifting or hoisting points for elevator installation are in place in the ceiling.
About ½ of the first elevator installation can be already completed at the point when the roof or ceiling above the hoistway is closed. The first elevator in the bottom section can already serve during construction as a construction time elevator while the building is still under construction.
When the building has reached said height of about ½ of the total height of the building, the protection deck can be installed which provides lifting or hoisting points for a man riding hoist and an overspeed governor.
The use of protection decks also protects the installers inside the hoistway. The use of the protection deck also provides an installation base at the bottom area of the top section.
During the construction of the building, site logistics can be improved for the transport of people and goods and based on better site logistics shorter construction time can be achieved. This means that finalized elevators can be handed over to the customer earlier.
Once the roof is closed the installation of the second elevator can start. After completing the installation of the second elevator, it can start to serve as a construction time use elevator for the full height of the building. The first elevator can be taken out of use and the installation of the first elevator can be completed. At least one elevator is ready for construction time use.
