Abstract: The present disclosure relates to an extended reality (XR)-based supervision assisting device, which finds a construction error by comparing a real design object photographed by a camera of the supervision assisting device with building information modelling (BIM) design data, and corrects the BIM design data to fit the real design object when the construction error between the real design object and the BIM design data exceeds a preset error tolerance range, thereby adjusting the BIM design data according to the construction error.

Abstract: Presented are an automatic design device for XR-based MEP facilities, and a method therefor, the device comprising: a position calibration unit for calibrating, to the current position of the automatic design device for XR-based MEP facilities in 3D construction site structure data, coordinates corresponding to a preset location in 3D construction site structure data including structure and coordinate information about a construction site, if the automatic design device for XR-based MEP facilities is located at the preset location of the construction site; and a location-tracking unit for tracking the location of the automatic design device for XR-based MEP facilities in the 3D construction site structure data on the basis of the current location when a user wearing the automatic design device for XR-based MEP facilities moves.

Abstract: Disclosed is an apparatus for improving construction precision based on extended reality (XR). At least one piece of XR content related to a construction target positioned in front inside a construction site is displayed on a display unit. When a construction position of a construction object included in the construction target is determined, the XR content including the design information of the construction object at the construction position is displayed on the display unit.

Abstract: The present disclosure relates to an apparatus for automatically designing an equipment line in BIM design data. When a plurality of pieces of equipment line installation data including a start point and an end point for equipment line installation in a construction site is input, an equipment line is automatically designed in the BIM design data based thereon.
