Construction progress monitoring is essential to construction processes. Automation of progress data capture during the construction process can address existing limitations and inefficiencies of the manual processes to enable systematic recording of construction progress. To achieve that, legged robots with the adaptability and mobility to traverse a variety of terrains on construction sites can be applied to automate on-site image capture. The goal of this research is to identify main criteria in effectiveness evaluation of technological performance of the quadruped robot in construction progress monitoring. This study investigates the implementation of legged robots in automating progress monitoring of construction through 360° image capture using Spot robot by Boston Dynamics. The study conducts a series of weekly experiments on two live construction sites to investigate robot-enabled reality capture in progress monitoring of construction projects. Core technological indicators and factors regarding economic justification and organizational performance of the new technology are explained.
