Earthworks are the integral part of any construction work in civil engineering and building construction. The construction activities performed during earthworks include the following: excavation, earthmoving, earth transport, and earth compaction. During earthworks, the excavation site is subject to harmful, flammable, or hazardous materials, damage to underground installations, the collapse of the earth, and many more risks. Therefore, construction work for trenching and excavation requires the implementation of adequate safety measures. This paper discusses the safety measures for workers during earthworks that involve excavations up to and exceeding one meter in depth.

Excavation Site

Of all the machinery and equipment used on construction sites, excavators are responsible for the greatest number of fatal accidents. Excavation is an inherently risky process due to imprecise work processes and the unstable external environment on most work sites. The resulting accidents cause serious injuries that threaten the lives of not only the excavator pilots but also those working around them. In this study, we propose a mechanical device that is capable of operating the excavator remotely from a nearby safe location such as a site office. To ensure worker safety and at the same time boost the productivity of excavation operations, data from 3D scanners, cameras, and sensors were combined to create a detailed 3D picture of the area surrounding the excavation site to guide a remotely operated excavating system. Rather than modifying the excavator itself, a removable manipulator was mounted on the joystick in the excavator’s cockpit. Our proposed system was tested on a standard commercial excavator to verify its performance for a real-world excavation task.

Unsafe Condition

Construction sites records high accident and incident rate due to lack of safety measures. Safety assessment rating is significant for every construction site to know safety status of the particular site. In this research TR safety observation method is used to assess the site performance. As unsafe condition is the key factor in every construction site, this research considers the possible unsafe conditions to assess the site performance. A questionnaire survey is done with the workers to know the existing safe conditions. Results showed that the safety performance of the site is 39%. Then every unsafe condition is ranked with respect to severity rating for detailed analysis. Furthermore bowtie analysis is used to identify the causes and consequences of the unsafe conditions. Through this analysis the owner can reduce the risk of every event and improve the site performance.

The Earth self-rotates in the solar and lunar gravitational fields. According to Newton’s Law of Inertia, large mass accelerates and decelerates more slowly than smaller masses, whereas small mass accelerates and decelerates more quickly than larger mass, which gives rise to stress when potential energy is present, damaging civil engineering projects. Humen Bridge of Guangdong, China and two century-old dams in Michigan which were affected recently can be explained by this theory.

PurposeThis study aims to (1) investigate the association between companies' investment in occupational safety and their financial performance and (2) discuss the importance of occupational safety to overall performance.Design/methodology/approachOccupational safety is often considered to be a practice that can yield suboptimal return on investment. However, it is not known whether this belief is substantiated by evidence. A mapping review of the eligible research literature (N = 36) regarding firms' investment in occupational safety and their financial performance, published between 1945 and2018, was carried out in the Web of Science database.FindingsBy dispelling myths regarding return on investment associated with occupational safety, the findings of this study underscore financial gains firms can obtain by promoting occupational safety measures in their organizations.Originality/valueThese issues are important because they can help policymakers understand the pressures companies face in terms of occupational safety and financial performance sustainability.

Sprayed Coatings

Environmental protection and worker safety measures against the extensively used hard chrome plating (EHC) is becoming more stringent, which leads to the development and application of alternative technology. As one of the most promising replacement technology of EHC, WC/Co coatings deposited by High Velocity Oxygen Fuel (HVOF) have well performances in corrosion and wear resistance. The paper analyzed technical characteristics, property and cost of EHC and HVOF deposited WC-Co coatings, while results show that performance of HVOF sprayed WC-Co coatings is superior or equal to EHC with much higher expense, so current replacement of EHC by HVOF centers airplane and military arm field which have relatively higher profit.
