Identifying And Evaluating The Perceptions Of Near-Miss Reporting Within The Kentucky Transportation Cabinet, Seth Atkins

Theses and Dissertations--Civil Engineering

In the field of construction, most safety data and practices focus on preventing and mitigating serious incidents resulting in injuries or fatalities. However, on construction sites, near-miss events occur more frequently than said serious incidents and, under marginally different conditions, could potentially lead to damages, injuries, or fatalities. Therefore, near-miss reporting can serve as a useful tool for managing safety as it allows for workers to identify and managers to address potential risk factors within construction sites. While most construction companies have implemented some method for reporting near-miss events, many organizations, such as the Kentucky Transportation Cabinet (KYTC), struggle with …

Theses and Dissertations--Civil Engineering

To combat understaffing in the construction industry, it is necessary to employ the best candidates possible. By identifying the most desirable skills in a construction employee from an industry perspective, institutional learning can better prepare graduates for the construction workforce. Currently there exists an information gap in the objectives of the construction industry and institutional learning. This gap produces graduates, professors, and employers with expectations that do not align. Reducing this gap will aid in the success of hiring recently graduated construction students who can meet the ever-changing demands of the industry. Construction students who are fresh out of college …

Design And Analysis Of A Pavement Marker Detection System, Timothy L. Johnson Ii

Theses and Dissertations--Civil Engineering

Personal injuries and property damage due to the failure of snow-plowable pavement markers which detach from pavement surfaces has led to the development of new all-plastic pavement markers which are located entirely below the planar surface of the pavement. The new all-plastic design pushes existing solutions used to avoid striping over highway reflectors into obsolescence since current solutions operate using electromagnets to sense the metal housings of snow-plowable pavement markers. A replacement solution is currently sought by the highway maintenance industry and three different marker detection methods were developed and tested on real-world highways with both new and aging pavement …

Redefining Construction “As-Built” Plans To Meet Current Kentucky Transportation Cabinet Needs, Victoria Lynn Lasley

Theses and Dissertations--Civil Engineering

As-built drawings are the traditional method used by the construction industry to record changes made during construction. As-builts provide valuable information for new design projects as well as rehabilitation and remediation projects. The completeness and accuracy of these plans are essential for transportation industries and their success. While the importance of as-builts is widely recognized, the process of creating them has proven to be difficult. It is a time consuming process and entities often lack the resources necessary to complete accurate and detailed as-builts. After an investigation of current as-built operations within State Transportation Agencies, recommendations have been made to …

Improving Safety Performance Of Highway Maintenance Crews Through Pre-Task Safety Toolbox Talks, Zamaan Al-Shabbani

Theses and Dissertations--Civil Engineering

The dangerous work environment in the construction industry and the inherent high risks associated with construction work make it the focus of safety training and regulations. Highway construction and maintenance has unique hazards but seemingly less directly applicable safety standards, regulations, and programs. Department of Transportation (DOT) employees working in highway maintenance are exposed to a variety of unique hazards specifically associated with their work and not relating to the adjacent traffic. Yet, highway construction and maintenance work has not received sufficient attention in terms of safety research and programs. The lack of safety training and education in highway construction …

E-Construction Technologies For Efficient Highway Construction Inspections, Dhaivat Patel

Theses and Dissertations--Civil Engineering

Over recent years, organizations such as the Federal Highway Administration and Departments of Transportation across the United States have showed interest in automating highway construction processes. The addition of e-Construction and other advanced technologies can significantly improve the efficiency and safety of highway paving operations, specifically paving inspections. Activities such as collecting load tickets, tracking pavement lay-down temperatures, and monitoring roller movement are antiquated practices that DOT inspectors perform during paving operations. E-Ticketing, Paver Mounted Thermal Profiling, and Intelligent Compaction were proposed to automate paving inspections and were recently tested in two resurfacing pilot projects in the state of Kentucky. …

Hazard Recognition And Risk Perception Among Union Electricians, Elyas Jazayeri

Hazard recognition and risk perception are two important factors that are a focus of most safety training programs. According to previous research, unrecognized hazards could lead to underestimation of risks, which ultimately could lead to injuries and fatalities. The primary objective of this research was to assess hazard recognition and safety risk perception skills in the electrician trade among electricians in unions. Another goal of this study was to find possible correlation between level of engagement in safety training and hazard recognition and risk perception skills. The research objectives were accomplished by gathering data from sixty-seven apprentices and journeymen across …

Advanced Technologies For Efficient Transportation Construction Inspection, Clyde Wesley Newcomer Iv

Theses and Dissertations--Civil Engineering

Collecting load tickets is an example of an antiquated practice that puts inspectors in harm’s way either adjacent to traffic, in close proximity to moving or backing equipment, or at times requires climbing onto trucks to reach tickets. Technology exists to collect this information electronically allowing for safer, efficient inspection methods. Departments of Transportation are charged with inspecting an increasing work load with a diminishing number of inspection staff. Recently, doing more with less has led to the prioritization of inspection activities and resulted in less collection of data and visual inspection on projects. Technology advancements are available to improve …
