The risk of losing institutional knowledge is a current problem at state departments of transportation, including the North Carolina Department of Transportation (NCDOT), due to high personnel turnover. State transportation agencies have implemented knowledge repositories in the form of lessons learned/best practices databases to address this problem. However, motivating end-users to use such databases is challenging. This paper addresses this challenge through novel artificial intelligence technology whereby a neural network–based language model is implemented as part of the NCDOT's new knowledge management program: Communicate Lessons, Exchange Advice, Record (CLEAR). The CLEAR program encompasses a database of lessons learned/best practices and a website to access and search the database. The developed methodology involves training a language model on transportation construction texts and using that trained model in a novel algorithm enabling users to search the CLEAR database easily. The developed language-processing model provides an easily accessible interface to suggest the most relevant CLEAR data based on the end-user's searched keywords. The model learns an inference model of construction domain–specific vocabulary extracted from various sources, such as contract documents, textbooks, and specifications, to make meaningful connections between lessons learned/best practices in the CLEAR database and project-specific knowledge. The developed model has been validated by project managers for projects at various life cycle stages. The automation of information retrieval is intended to encourage NCDOT personnel to use and embrace the CLEAR program as part of their routine work to improve project workflow. In the long run, the NCDOT will benefit from consistent usage of the CLEAR program and its high quality content, thereby leading to enhanced institutional knowledge and organizational innovation.}, number={3}, journal={JOURNAL OF COMPUTING IN CIVIL ENGINEERING}, author={Banerjee, Siddharth and Potts, Colin M. and Jhala, Arnav H. and Jaselskis, Edward J.}, year={2023}, month={May} }

These injuries sometimes result in irreversible damage, life-long disability, and even the loss of life. Therefore, strategic initiatives to reduce work-related injuries are necessary. To help achieve this goal, the Occupational Safety and Health Administration (OSHA) recently introduced a new severe injury reporting program. The program requires that employers notify OSHA of any severe or serious injuries that result in amputation, in-patient hospitalization, or loss of an eye within 24 h. The current investigation statistically examined more than 11,000 physical injuries reported as part of this program to identify patterns and discover opportunities to enhance workplace safety. The key findings include: (1) the most commonly reported severe injury event types are falls to lower level and struck-by object or equipment incidents; (2) the most commonly reported injury sources are ladders and structural elements such as joists, roofs, and skylights; (3) the most commonly reported injured body parts are the upper extremities and the lower extremities; (4) the most commonly reported nature of injuries are traumatic injuries to bones, nerves, and spinal cord (e.g., fractures) and open wounds; (5) the most reportedly vulnerable construction sectors for severe injuries are commercial and institutional building construction and electrical contractors and other wiring installation contractors. The findings also offer insights into the relationship between injury attributes. For example, the event type "falls to lower level" was particularly likely when workers used the injury source "ladders per the data." The findings can be leveraged to enhance work-related safety among construction workers.}, journal={SAFETY SCIENCE}, author={Alsharef, Abdullah and Albert, Alex and Awolusi, Ibukun and Jaselskis, Edward}, year={2023}, month={Jul} }

This ongoing issue gives rise to the need to impart fresh training to new North Carolina Department of Transportation (NCDOT) employees once the aging workforce retires or in the event of turnover. In addition, a platform for personnel to record pertinent project information about successes and failures in projects is needed. Such information can help solve problems and avoid repeated mistakes. The aim of this research project is to create a new program called Communicate Lessons, Exchange Advice, Record (CLEAR) to reposit knowledge gained by personnel. Integral to this program is an internal-only web-based database on NCDOT’s Connect SharePoint portal with MS Access as its backend. The North Carolina State University researchers used a Design for Six Sigma approach to identify, define, develop, optimize, and verify lessons learned/best practices to create the CLEAR database. The database fields were selected based on end-user input as well as a review of existing data, such as claims and supplemental agreements, within NCDOT data repositories. Training materials, including videos and standard operating procedures, were created to disseminate information about this new program. The CLEAR program will help the NCDOT to institutionalize knowledge and is expected to improve project cost variability and scheduling. }, number={7}, journal={TRANSPORTATION RESEARCH RECORD}, author={Fullerton, Clare E. and Tamer, Alyson W. and Banerjee, Siddharth and Alsharef, Abdullah F. and Jaselskis, Edward J.}, year={2021}, month={Feb} }

This study focused on investigating the early impacts of the COVID-19 pandemic on the U.S. construction industry since the declaration of the national emergency on 13 March 2020. The study objectives were achieved through 34 telephone interviews with project managers, engineers, designers, and superintendents that represented different states and distinct industry sectors in the United States (U.S.). The interviewees offered information on their experience with the pandemic, including the general and adverse effects experienced, new opportunities created, and risk management efforts being undertaken. The reported adverse effects included significant delays on projects, inability to secure materials on time, reduction in productivity rates, material price escalations, and others. The new opportunities that were created included projects involving the fast-track construction of medical facilities, construction of residential buildings, transportation-related work, and opportunities to recruit skilled workers. The risk management measures that were widely adopted included measures to enhance safety and reduce other project risks. The safety measures adopted included requiring employees to wear cloth face masks, adoption of social distancing protocols, staggering of construction operations, offering COVID-19-related training, administering temperature checks prior to entry into the workplace, and others. Measures to manage other project risks included the formation of a task force team to review the evolving pandemic and offer recommendations, advocating that construction businesses be deemed essential to combat delays and taking advantage of government relief programs. The study findings will be useful to industry stakeholders interested in understanding the early impacts of the pandemic on the construction industry. Industry stakeholders may also build upon the reported findings and establish best practices for continued safe and productive operations.}, number={4}, journal={INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH}, publisher={MDPI AG}, author={Alsharef, Abdullah and Banerjee, Siddharth and Uddin, S.

Nonetheless, these examiners themselves are exposed to high levels of safety risk as they test new drivers – with limited driving proficiency and experience. A deeper understanding of the safety incidents that driver license examiners experience can inform the development of effective injury prevention policies and interventions. Towards achieving this goal, the current study focused on performing exploratory content analyses of safety incident reports maintained by the North Carolina Division of Motor Vehicles (NCDMV) that involved driver license examiners. Apart from demonstrating that numerous incidents are experienced during driving tests, the five key findings include the following: (1) The most common event types that driver license examiners experience are collision with fixed object, overexertion and physical bodily reaction, and collision with another vehicle; (2) The most common contributing factors are failure to maintain control of vehicle and incidents experienced while examiners are exiting the vehicle; (3) Most incidents that result in injury involve injuries to multiple body parts, followed by injuries to the back, leg, and neck; (4) The most common injury types are strain, sprain, and bruising and contusion; (5) The injury outcomes are medical case, permanent disability, report only, and temporary disability. The results also reveal particular relationships that are overrepresented in the incident reports. For example, collision with fixed object is associated particularly with failure to maintain control of vehicle. The findings can inform future efforts that seek to reduce injury rates among driver license examiners.}, journal={SAFETY SCIENCE}, publisher={Elsevier BV}, author={Alsharef, Abdullah and Albert, Alex and Uddin, S.

DOTs are increasingly using instrumentation and sensor technologies for delivering highway projects across the U.S.A. Instrumentation devices and sensors include such technologies as remote sensing, real-time kinematics, global positioning systems, digital handheld devices, ground penetrating radar, and intelligent compaction/thermal profiling. These technologies are becoming commonplace in highway construction because of their capabilities to improve the construction process by making activities more efficient and more productive. However, the practices in using instrumentation and sensor technologies for highway construction vary among state DOTs. Therefore, this study investigates how DOTs employ the use of instrumentation and sensor technologies for highway construction. This study engaged a research methodology that included an extensive literature review, survey questionnaire, and case studies of state DOTs. Results show that 31 state DOTs use instrumentation and sensor technologies for monitoring work progress, conducting quality control and quality assurance, performing construction inspections, identifying optimal conditions and recording the placement of work, and locating utilities. The main barriers to using instrumentation and sensor technologies include analyzing the large amount of data, verifying the accuracy of the data, ensuring staff have the skills and knowledge to use the technologies efficiently, and assisting smaller contractors to gain the knowledge to use these technologies. The findings from this study provide recommendations and strategies for DOTs to implement instrumentation and sensor technologies effectively for highway construction. }, number={9}, journal={TRANSPORTATION RESEARCH RECORD}, author={Harper, Christofer M. and Tran, Daniel and Jaselskis, Edward}, year={2020}, month={Sep}, pages={593–604} }

We are as pleased and as proud now as we were then to present a series of papers that bridge construction engineering academics and industry practitioners. The need for increased collaboration between academia and the industry has not subsided, and will not subside in the foreseeable future. The construction engineering academic community faces the challenge of maintaining a balanced research portfolio of both basic and applied research. Both types of research are dependent on each other in the overall spectrum of our community and feed the cycle of continuous improvement in the engineering and construction industry’s performance.

The papers contained in this special issue follow three primary themes that mirror the theme of the overall 2014 Construction Engineering Conference. The first theme focuses on aspects of knowledge and career paths for future success. Many of these particular papers focus on the challenges, benefits, and lessons learned integrating industry knowledge into education and research at the universities. The second and third themes, sustainability and building informationmodeling (BIM), focus on specific areas of new knowledge that will continue to become increasingly critical for both the success of individuals and also the industry at large. Papers along these particular themes focus on how sustainability andBIM are not only being implemented in the industry, but how these relatively new practices are being addressed in university curriculums.

Researchers conducted structured interviews with 56 subject matter experts to investigate and map widely adopted and novel practices, specifically addressing certain “key” groups of IDCC. The rich findings from these interviews have been aggregated into an instructional guidebook which includes empirical consideration checklists, comprehensive process flowcharts and practical tools. Eighty-nine percent of interviewees reported that project success can be improved through better handling of IDCC. This research seeks to fill this performance gap by enabling owners and contractor to easily adopt the recommended practices into standard operating procedures. To establish a shared vocabulary for IDCC, this paper summarizes literature pertaining to IDCC and proposes a two-part operational definition comprised of a lexical definition and a categorization framework. The findings are outlined from a contractor’s perspective and focus on costs most commonly incurred by construction companies at the project level. This paper presents a partial consideration checklist and a process flowchart for major construction equipment. Lastly, this paper describes the on-going validation methodology.}, booktitle={Construction Research Congress 2012}, publisher={American Society of Civil Engineers}, author={Becker, Timothy C. and Jaselskis, Edward J. and El-Gafy, Mohamed and Du, Jing}, year={2012}, month={May} }

The objective was to identify sustainable engineering practices that apply to modern practice. Travel to the Inka Road in the highlands of South America is difficult; thereby creating a challenge for bringing together students, technical experts, and other interested parties for real-time information sharing and collaborative research. In order to meet this challenge, the research teams joined forces with the Smithsonian Institute’s National Museum of the American Indian and streamed live interactive broadcasts from the cordillera of Peru to audiences in Washington D.C. Pioneering the use of satellite-based audio and video communication equipment, the on-location researchers were able to share and explain the physical conditions of the Inka Road with museum visitors and experts in real time. Participants at the Smithsonian were able to ask questions in an interactive, 2way dialogue with the field teams. On-site researchers were able to inquire of experts, located in different parts of the world, questions regarding possible Inka findings. The broadcasts from the Inka Road provide a proof of concept example of tele-engineering from a very extreme environment. This paper explains the teleengineering concept and how it was used to help reverse engineer the Inka Road.

These skills, while fostered in the classroom, require a contextual learning environment to allow students to personalize the information. Using a constructivist approach allows these skills to be acquired and improved over time. This type of learning environment was created during a field research project supported by a National Science Foundation, Pan-American Advanced Studies Institute (PASI) grant, where two teams of multi-disciplinary researchers traveled to areas of Peru to reverse engineer the Inka Road with the objective of identifying sustainable engineering practices. The teams consisted of engineers, architects, constructors, archeologists, anthropologists, historians, a music culturist, and a high school student. Additionally the team members were from three different continents representing seven different countries and were a mix of faculty, graduate students, undergraduate students, and industry professionals. The work undertaken required documenting engineering and construction practices of the ancient Inka Road and its associated structures, to include hydraulic channels, terraces, retaining walls, storage areas and ritual sites. While in the field the outcomes of the daily work was shared with an audience at the Smithsonian Institutes National Museum of the American Indian via live interactive satellite broadcasts. These broadcasts were also available over the internet. This required the teams to work cooperatively in an unpredictable physical and time constrained environment to ensure success of the broadcasts. Team members came to understand the challenges of working together with unfamiliar people speaking various languages and utilizing discipline specific terminology. This setting provided participants with the opportunity to develop a greater understanding of the skills required to be successful working in these types of teams.

Empirical results of this study show that the proposed model outperforms traditional financial ratio models in differentiating the risk of defaulted and nondefaulted construction contractors.

In no other engineering specialization is this more relevant than in construction engineering. A challenge among construction engineering academics (both faculty and students) and industry practitioners is to transfer a method, technology, or practice that can be supported in the theoretical sense, whether in a laboratory or classroom setting, and make it applicable to the rarely ideal industry jobsite. This bridge between engineering in the theoretical sense and practice requires intimate collaboration and continuous communication, which has not always occurred between the university and the jobsite. As described by Dr. Michael C. Vorster, professor emeritus at Virginia Tech and conference keynote speaker, the dilemma from the academic perspective is that “we teach too much and our students learn too little.” A primary focus of the Construction Engineering Conference held at Virginia Tech from September 30 to October 2, 2010, was to bring academics and industry leaders together to share experiences, practices, and ideas. This interaction was intended to strengthen the connection between theory and practice for mutual benefit. The Construction Engineering Conference was a unique opportunity in the sharing of knowledge across aisles. The purpose of this special issue is to archive and disseminate the knowledge for current and future generations of construction engineers. Each conference speaker submitted a manuscript that was peer-reviewed by academic and industry reviewers. In many cases, industry speakers coauthored the manuscript with a construction engineering academic. In all, this special issue includes 28 manuscripts that cover a broad range of construction engineering topics. A debt of gratitude is owed to the authors for their thoughts and efforts in this overall body of work, which makes a significant contribution to the overall body of construction engineering knowledge. Furthermore, the editors are especially grateful to the reviewers, who ensured that the manuscripts maintained the rigorous standards for publication in the ASCE Journal of Construction Engineering and Management.

A concrete paver manufacturer and a machine guidance solution provider developed this technology and successfully implemented it on construction earthmoving and grading projects. Concrete paving is a new area for considering this technology. A concrete paving contractor in Iowa agreed to test the stringless paving technology on two challenging concrete paving projects located in Washington County, Iowa during the summer of 2003. The research team from Iowa State University monitored the guidance and elevation conformance to the original design. They employed a combination of physical depth checks, surface location and elevation surveys, concrete yield checks, and physical survey of the control stakes and string line elevations. A final check on profile of the pavement surface was accomplished by the use of the Iowa Department of Transportation Light Weight Surface Analyzer. Due to the speed of paving and the rapid changes in terrain, the laser technology was abandoned for this project. Total control of the guidance and elevation controls on the slip form paver were moved from string line to a global positioning system (GPS). Results indicate that GPS control is a feasible approach to controlling a concrete paver.
