Utilization Of Drones as A Tool For Monitoring Progress In Civil Engineering Construction Using Enugu State As A Case Study

Abstract

The hazardous nature of the Nigerian building construction sector is alarming due to the dearth of construction data and records of incidents that have led to the loss of life, property damage, injuries, and loss of materials on construction sites This study aims to assess the effectiveness of drone monitoring of security and safety at Nigerian building sites in reducing hazardous site conditions. The following hypotheses were made to meet the study's goal and objective to assess the level of drones using Enugu State in Nigeria as a case study. The Methodology includes a literature survey and questionnaires at various sites. 242 people responded to the survey. To assess the constraints of employing quadcopters and other drones/UAVs (unmanned aerial vehicles) for safety and security surveillance on construction sites in Enugu State, Nigeria. Inventive drones and the DJI Phantom 3 Standard Both types of drones were used in this experiment. The targeted experts and stakeholders included architects, builders, engineers, quantity surveyors, land surveyors, estate surveyors, and clients. The data were analyzed using the SPSS computer program for Windows, version 23.0. Only 65 per cent of respondents were aware of the drone idea, although 51 per cent of respondents used drones in various construction monitoring sectors. The adoption rate of 17.6% for safety and security monitoring, however, was deemed low by participants in the Enugu State building construction sector. Drones have been successfully used in developed countries such as America, Europe, China, Australia, and India, to monitor safety and security as well as the progress of both large-scale and high-rise construction projects. As a tool for monitoring the security and safety of all building phases, drones are still in their infancy from the Nigerian perspective. The successful use of drones in Nigeria is encouraged since realistic imagery generated from drones may be used for analysis and evaluation of ongoing construction work, including planning movement on site and monitoring materials on site and may be archived for future purposes
