Drawings are the most basic element to carry out construction works. Managers and workers in the construction site build facilities like houses and offices with 2 dimensional (2D) printed drawings into 3 dimensional (3D) real world. If an error occurs in the process of recognizing 3D from 2D drawing, damage may occur in quality, cost, and time of building construction. Creating all the elements of a building as a 3D model through VR (virtual reality) or BIM (building information modeling) can reduce design and construction errors, but the time and cost of implementing them as 3D models are not small. This study proposes a method of supporting construction management by constructing 3D models only of necessary parts of 2D drawings and implementing 3D models on drawings through AR (augmented reality) in smart devices. A drawing used as an image marker and a 3D model made by SketchUp are connected in Vuforia included in Unity. And The function that temporarily hides unnecessary parts can be implemented in C# programming language. If an owner, an architect, or a contractor looks at a smart phone on a 2D drawing under construction, they can identify building elements such as 3D buildings or columns on a screen. The Android-based augmented reality application is helpful for communication between them.
