Abstract
A reference core position calculation devicethat calculates a reference core position of an elevator shaft in which an elevator is to be installed includes a measurement unitand a calculation unit. The measurement unitmeasures a dimension of each portion of the elevator shaft. The calculation unitcalculates portion dimension values of the elevator shaft based on the reference core position and the dimension of each portion measured by the measurement unit. When the reference core position is a first reference core position, the calculation unitdetermines whether portion dimension values of the elevator shaft calculated based on the first reference core position satisfy a predetermined specification.
