TL;DR: In this paper, the authors assess the applicability of UAV for safety inspection on construction sites, focusing on the identification of the requirement that can be inspected and the non-compliances with the safety requirements established.

TL;DR: The study sought to examine three main constructs related to the 3D mapping developed: the easiness of development, the quality of the models in accordance with the proposed use and the usefulness and limitations of the mapping for construction management purposes.

Abstract: Construction progress monitoring may help for an efficient management process as planned. Studies have proposed the use of visual data technologies; however, little has yet been done for the development and implementation of methods for integrating such technologies into construction management routine. This study aims to implement and evaluate the proposed method for systematic visual progress monitoring integrating into the production planning and control process, supported by 4D BIM, photogrammetric 3D mapping using Unmanned Arial System imagery, and performance indicators. The proposed method was implemented for 20 weeks in a case study on a construction project. The data collection included construction site 3D mapping generation, visual comparison of 4D BIM and 3D mapping status, measurement of performance indicators, and structured interviews. The evaluation focused on the following research constructs: compliance with the planned goals, impact on the construction progress deviations, transparency, and collaboration. The main findings indicate an improved integration of progress analysis and decision-making, improvement of progress deviations’ identification, and allowed for better compliance with planned goals and increased transparency and collaboration. The main contribution of this work is a better understanding of the impact and added value of the new information flow provided by using the proposed method.

TL;DR: A literature review was carried out for papers dated from 2008 to 2018 using Scopus database and indicated that the development of progress monitoring automated systems, the use of 3D as-built point cloud models and Building Information Modeling are the most frequently discussed subjects within the papers surveyed.

TL;DR: This paper aims to evaluate the application of UAS for safety inspection on site, focus on its utility, equipment performance and risks associated with the use of that technology.
