Application of Ultrasound Sensor in Construction Safety: Study of Struck-By Hazard

Abstract

Objectives: To accesses the impact of the sensors in preventing from struck-by hazards in the construction sites; To compare the suitability of available sensor technologies in prevention system of struck-by hazard. Method: The current demand of construction industry is to complete project in the minimum time, to achieve the goal of safety as construction sites are getting complex in terms of management challenge. Available proximity sensors were examined to choose an appropriate sensor for using in early warning system to prevent from struck-by hazards. An early warning system was proposed using ultrasound sensor, that will warn the vehicle operator by visual and acoustical methods to stop the vehicle before collision between vehicle and personal / equipment / material and will prevent from struck-by hazards. Findings: It has been proven that blind spots (visibility problem) are the main reason for struck-by accidents. Ultrasound sensors uses sound technology, so that, they are suitable to detect objects in non-visible conditions (Rain, Fog, Night etc.). Ultrasound technology is independent and does not necessitate external hardware installation or processing facilities once it is integrated on the machinery. Proposed early warning system will help construction managers to manage sites more effectively. Novelty: Many researchers have done various studies on struck-by hazard prevention in construction. However, there is no enough focus on, particularly using ultrasound sensors to prevent from struck-by hazards. Hence to assess the capability and use of ultrasound sensors in this area of construction is been done
