Measuring And Evaluating Safety Maturity Of Construction Contractors: Multicriteria Decision-Making Approach, Ali A. Karakhan, Sathyanarayanan Rajendran, John Gambatese, Chukwuma Nnaji

All Faculty Scholarship for the College of the Sciences

Evaluating the safety maturity of construction contractors before awarding the contract is an effective strategy that many owners have started to implement. Given the importance of workplace safety, awarding the contract to safer contractors can enhance project performance outcomes in terms of safety, quality, cost, and schedule. Safety maturity is one quality of a construction organization encompassing interdependent factors that can be used to evaluate expected safety performance. However, there is no formal decision-making framework available in literature that owners can use to evaluate contractor safety maturity. The present study aims to bridge this gap in safety knowledge by proposing …

Industrial-Grade Monitoring Solution: Hoistcam, Purdue Ect Team

ECT Fact Sheets

Research-To-Practice (R2p) Tools For Improving Safety In Nighttime Highway Construction Work Zones, Ali Mostafavi, Vanessa Valentin, Dulcy Abraham

Infrastructure System-of-Systems (I-SoS ) Research Group

The safety of workers in nighttime roadway work zones has become a major concern for state transportation agencies due to the increase in the number of work zone fatalities. During the last decade, several studies have focused on the improvement of safety in nighttime roadway work zones; but the element that is still missing is a set of tools for translating the research results into practice. This paper discusses: 1) the importance of translating the research results related to the safety of workers and safety planning of nighttime work zones into practice, and 2) examples of tools that can be …

Cranium: Device For Improving Crane Productivity And Safety, Purdue Ect Team

ECT Fact Sheets

Cranes are the most important pieces of equipment on many construction sites. CRANIUM is a video system designed to improve productivity and safety of crane operations by improving communications. A video camera mounted on the crane bottom transmits an image to the television monitor in the crane cab. The operator has a real-time picture of the loads and craftsmen that might otherwise be out of the direct line of sight.

3m Personal Air Monitoring Systems, Purdue Ect Team

ECT Fact Sheets

3M monitors are made to allow sample desorption directly in the monitor itself. The monitor comes with a snap-on elution cap that permits the desorbing solvent to be injected into the monitor. The solution is then poured into sample vials for analysis. 3M monitors use standard analytical methods: gas chromatography for the organic vapor monitor and ethylene oxide monitor, and colorimetry for the formaldehyde monitor.

Delmia Safework®Pro™ : Human Modeling, Purdue Ect Team

ECT Fact Sheets

Manufacturers and designers strive to develop products that conform to all relevant Health and Safety standards and are "user-friendly" while still maximizing the productivity of their own workforce. Digital human modeling technology can assist a designer to determine the performance of people in the context of a workplace or a product before it exists and throughout its entire lifecycle. SAFEWORK’S accurate manikin has the highest number of Anthropometric Variables (104), Segments (99) and Degrees of Freedom (149). It also has fully articulated spine & hand models as well as joints with coupled range of motion. Moreover, it’s unique Multivariate Algorithm …

Pipeman:Safety In Trenches, Purdue Ect Team

ECT Fact Sheets

Even though heavy construction equipment such as a crane or backhoe excavator, is used to perform the task of pipe laying in the trench, workers are required to be inside the trench to guide the excavation, pipe laying, and final alignment. Work place safety has become a major concern in the construction industry over the past few decades, and trench cave-ins have caused serious and often fatal injuries to workers in the United States. The Construction Automation and Robotics Laboratory(CARL) at North Carolina State University has developed an alternative which involves advanced new technology: the prototype robotic excavation and pipe …

Behavior-Based Safety In Construction, Purdue Ect Team

ECT Fact Sheets

Behavior-based safety approach that was introduced into the United States in 1930's and has been popular in manufacturing area since 1980's assumes that many of injuries and illnesses are the result of unsafe acts by workers. Behavior-based safety is a proactive approach to increasing safety in the workplace and in the community. It is based on sound, research-based, and behavioral practices, and are easy to use with minimal training.

Safe Excavation, Purdue Ect Team

ECT Fact Sheets

Excavating with a backhoe or similar equipment has the potential risk of hitting an underground utility which could cause serious injuries and expensive damages. An electronic device that provides a real-time warning of the utility lines immediately ahead of the digging tool and provides an easily interpreted, real-time computer readout of the depth, location, and size buried metallic objects. Developed by Dr. Leonhard E. Bernold, it consists of an active metal detector search coil; a signal processing (control) unit; and a PC computer equipped with an analog-to-digital converter interface.
