Abstract: A computer system generates a three-dimensional (3D) visualization of a building structure that is undergoing construction. The system can determine a location of an object in the building structure and map the object to an expected object in a 3D model of the building structure. The system can detect a discrepancy between the object of the building structure and the expected object in the 3D model, and determine that the discrepancy exceeds a threshold, which constitutes a reportable error. In response, the system can determine a modification to the building structure to compensate for the discrepancy, adjust a schedule for construction or a cost estimate to compensate for an impact of the discrepancy or the modification to the building structure, and send a message that reports the discrepancy and the modification.

Abstract: Methods, apparatuses, and embodiments related to a technique for monitoring construction of a structure. In an example, a robot with a sensor, such as a LIDAR device, enters a building and obtains sensor readings of the building. The sensor data is analyzed and components related to the building are identified. The components are mapped to corresponding components of an architect's three dimensional design of the building, and the installation of the components is checked for accuracy. When a discrepancy above a certain threshold is detected, an error is flagged and project managers are notified. Construction progress updates do not give credit for completed construction that includes an error, resulting in improved accuracy progress updates and corresponding improved accuracy for project schedule and cost estimates.
