<align="justify">UAVs evolved and can now be used for civilian purposes such as inspection, surveying, mapping, up to three-dimensional modeling. Three-dimensional modeling of measurement results using UAV photogrammetric method has many applications, like construction monitoring. This research aims to create a three-dimensional model of the Antapani Flyover construction progress from the measurement results of close range photogrammetry method using a UAV. Observation methods was done by aerial photo data retrieval. The aerial photo data are processed through digital photogrammetry process to obtain the point cloud. The check scale bars are made to produce a model with an accurate size. The model, which is still shaped by point cloud, is then processed into orthophoto with low-accuracy georeferencing. After the process is done six times, postmark planning is done for further GPS measurements. Postmarks which have been measured using GPS are then used as the control point to produce models with precise coordinates, so the models will not shifted from their position at each data retrieval. Then the point cloud is processed into a mesh to produce a model in the form of a flat surface. Meshes of all six data processing results can already be part of the BIM process, which can be used for construction monitoring, based on RMSE of the check scale bars, referring to USIBD accuracy standards. From the results of the all six data processing, the results obtained RMSE of check scale bars based on the data, sequencing from the first data to the last data are 17, 13, 18, 37, 19, and 39, in milimeters. These results meet the standards of LoA20 for the first, third, fourth, fifth, and the last data, and the standards of LoA30 for the second data.<align="justify">
