Application of Web Services for Structural Engineering Systems

The Internet has revolutionized the way computing is done and the way software systems work. Many systems, such as search engines and PC games, have utilized Web-related technologies for Web-based systems. However, the application of Web-based engineering software is still in its infancy, especially regarding engineering computing. This paper presents a prototype development of Web-based structural engineering systems by utilizing modern computer graphics and information technology to provide Web-based analytical services. The system design emphasizes platform-independence, graphical interface, system performance, and a multiple-user environment. The user needs only an Internet-connected machine to access high-performance services provided at remote sites over the Web. This framework will provide users a powerful tool to efficiently perform analysis with minimal computer resource requirements. The user will always have access to the most up-to-date and functional system with no client-side updates or maintenance required. Two Web-based system implementations are given as examples in this paper.     

Use of Multimedia and the World Wide Web in Civil Engineering Learning

The case study method, which has been proven to be a very useful learning tool, can be further enhanced with the use of multimedia and the World Wide Web. This paper demonstrates multimedia and Web-based enhancement with the design and construction of a port, a large-scale civil engineering project. The main purpose was to create an educational tool that brings into the classroom a “real-life” design and construction problem, including the construction field, operation of equipment, and details of construction methods. This enables civil engineering students to better understand the details of the planning, design, and construction of a complicated project. Furthermore, through the use of evaluation tests, feedback on the students’ understanding of the case study can be provided to both the students and the educator. This application can be expanded beyond an academic environment for use as a learning tool in a business environment, which may be especially beneficial for new engineers.

Impact of Nanotechnology on Future Civil Engineering Practice and Its Reflection in Current Civil Engineering Education

Current civil engineering education should address the need to provide a broad vision, develop the higher-order skills of future civil engineers, enable them to adopt emerging technologies, and formulate innovative solutions to complex problems. This paper introduces relevant nanotechnology developments to convey the new vision and inspire creativity in civil engineering. It also presents a pedagogical framework for integrating nanotechnology education into a civil engineering curriculum and cultivating self-regulated learning and creativity skills for civil engineering students. The pedagogical framework includes the introduction of nanotechnology innovations and other relevant innovative technologies, and explicit instructions on cognitive strategies for facilitating and inspiring self-regulated learning and creativity. It is implemented with problem/project-based learning for a cocurricular project that requires self-regulated learning and creativity. This pedagogical framework provides a model for integrating emerging technology education and higher-order skill development into existing engineering curriculum. The outcomes from the implementation of the pedagogical framework are presented, and their further improvements are discussed.     

The Civil Engineering Resource Library

The delivery of civil engineering projects requires civil engineers to address a broad spectrum of issues generated by both project participants and regulatory agencies. Providing tools that assist team members in addressing these issues through the use of information and knowledge from previous projects may reduce project errors by creating informed decision makers. Recent advances in communications and computer technologies provide the opportunity to enhance professional and student access to these resources. The Civil Engineering Resource Library research effort explores this opportunity by combining an introduction to civil engineering processes with emerging web-based technologies for an electronic classroom supplement. The electronic library uses case studies to provide students with illustrations of emerging civil engineering practices and regulatory compliance strategies.     

Empirical Study on the Merit of Web-Based 4D Visualization in Collaborative Construction Planning and Scheduling

This paper reports an empirical study that tested the usefulness of Web-based four-dimensional (4D) construction visualization in collaborative construction planning and scheduling. Several recent construction projects have employed 4D visualization to better understand the construction schedule and make proactive decisions to prevent logical errors in the construction sequence. Other groups have shown that construction information management with asynchronous Web-based communication can improve decision making among dispersed industry practitioners. It seems reasonable to anticipate that combining 4D visualization with Web-based information management would facilitate dispersed industry practitioners to make collaborative decisions for construction planning and scheduling. The empirical study presented here reports how experiment participants at separate locations collaboratively detected logical errors in a construction schedule when the 4D visualization model of the schedule was represented on the Web browser. Our results show that teams using 4D models detected logical errors more frequently, faster, with fewer mistakes, and with less team communication, than teams using 2D drawings and bar charts. These findings show industry practitioners empirical evidence that Web-based 4D construction visualization can improve team collaboration on construction planning and scheduling.     

Embedding Leadership in Civil Engineering Education

Leadership is a key element in meeting the needs of the civil engineering profession in an era of heightened global competition. Consulting and construction executives intent on maintaining a competitive edge are calling upon educators to produce civil engineers capable of leading multidisciplinary teams, combining technical ingenuity with business acumen, and effectively communicating narrow engineering endeavors within a comprehensive social framework. Our industry is challenging undergraduate schools to broaden curricula beyond the intellectual endeavors of design and scientific inquiry to the greater domain of professional leadership. Many agree that formal leader development must be incorporated into engineering education programs to respond to the professional demands of practicing engineers; however, the means of achieving the objectives within tightly constrained curricula are debated. This paper explores the changing nature of civil engineering in a globally competitive environment, reviews the issues in realigning civil engineering education, identifies key leadership skills relevant to engineering, and proposes solutions for developing leaders at our undergraduate institutions.     

Information Technology in Civil Engineering Curriculum

The fast-moving world of information technology confronts the civil engineer with constant change. This creates challenges for educators and students because rapid change requires curricula to be flexible and educators to gain competency and access to new equipment and software. Whereas a decade ago, civil engineering educators debated how to teach “programming,” the picture is now much more complex. The paper reports on how information technologies are changing the practice of civil engineering and offers a new framework for integrating next-generation information technology into the civil engineering curriculum at the department level.     

Being Brave in the Brave New World

As civil engineering enters the 21st century, there are four issues engineers need to confront in order to improve the profession. These are time, teams, technology and stewardship. In the future, diminishing project completion times will require engineers to develop new methods of time management without sacrificing project quality. In terms of teamwork, project managers will increasingly need to be broad-scale leaders, with the ability to manage people as well as the technical aspects of a project. Engineers should also evaluate technical issues, focusing on the ethical implications of doing what is only technically correct instead of looking at the overall project. Finally, civil engineers should explore the profession's ethical responsibilities, questioning what role civil engineers should play in terms of stewardship in the social, global and political arenas.     

Web-Based Decision Support Systems: Case Study inProject Delivery

The decentralized nature of the construction industry contributes to difficulties in the implementation and dissemination of project management-based decision tools. The majority of decision support systems (DSS) are contained in-house with private developers and users, or on researchers stand-alone computers and academic journals. Current World Wide Web technologies provide the appropriate means for large-scale implementation and continued development of DSS for the architectural, engineering, and construction community. This paper documents a DSS developed specifically for design∕build project selection among United States public sector agencies. The system, the Design∕Build Selector (DBS), is Web enabled, allowing for easy access and large-scale dissemination. Design∕build project procurement is rapidly expanding throughout public sector agencies in the United States construction industry. As public agencies turn to design∕build, appropriate project selection is a primary consideration affecting successful delivery. Prior to the implementation of DBS, there was no systematic or formalized method for selecting projects appropriate for design∕build. Since 1997, the Web site that houses the DBS has been visited by over 4,000 people, and the DBS tool has been used on 102 projects representing over $4.8 billion in construction. This paper reports on the application and potential for Web-based DSS in civil engineering. The architecture of the program, data collection, model weighting, and output interface are explained.     

Demographics and Industry Employment of Civil Engineering Workforce

This paper provides a road map to studies and databases about civil engineering demographics and industry involvement by tracing workforce statistics, engineering degrees, data on industries and government, and economic forecasts. It is aimed at helping civil engineering managers, educators, and policy makers understand how their workforce evolved and what it will face in the future. The engineering workforce comprises about 1.5 million professionals in the United States (second in size only to that of teachers); of this number, civil engineering, at about 200,000 workers, is third behind electrical and mechanical engineering. However, the study shows that aggregation of workforce and economic statistics hides unique characteristics of civil engineering work caused by the concentration on consulting and state and local government. In fact, over 80% of civil engineers work either for consultants or government. This characteristic of civil engineering employment needs more study, particularly to determine how best to educate civil engineers to respond to the public–private arena of infrastructure and environment. During the past century, civil engineering has been a steady field with good opportunities, but civil engineers in the future will face the same career issues and pressures as other professionals. Global production of new engineers has now passed the one million-per-year mark, with U.S. production being about 12% of the total. This large supply of engineers will present intense competition to all engineering disciplines. ASCE faces many challenges to respond to the many changes in the civil engineering profession. The concept of institutes contained in ASCE's strategic plan will address many of the technical issues, but the study indicates that professional and educational issues need more attention.     

Innovation in Construction Engineering Education Using Two Applications of Internet-Based Information Technology to Provide Real-Time Project Observations

Improvements in construction engineering education result when innovative information technologies are incorporated into academic curricula. Through the use of internet-based communication technologies, no longer must students physically travel to a construction project site to observe and hear construction operations. This paper discusses two applications of internet-based, audio and video technologies currently being piloted at Iowa State University (ISU) and at the University of Calgary (UC) for the purpose of bringing live construction projects into the university classroom. Virtual Project Tours have been piloted at Iowa State University in which real-time video and audio are delivered from active construction projects to a remote classroom through the internet. The second application discussed in this paper, Virtual Supervision, is being piloted at the University of Calgary and consists of the monitoring and analysis of construction projects by using imagery gathered by web-enabled, digital cameras of fixed location transmitting video through the internet. This paper also presents a vision of a globally networked organization of engineering and construction education institutions each sharing the unique engineering and building techniques of their respective part of the globe with design and construction students located around the world. This exchange of construction project observations among the institutions will be enabled by the internet-based applications of virtual project tours and virtual supervision systems described in this paper.     

Preparing Civil Engineers for International Collaboration in Construction Management

Economic globalization is increasingly affecting both the construction industry and academia. It is changing the traditional roles of civil engineers and construction managers. Cross-cultural collaboration and communication skills, multinational team management skills, the ability to overcome the social challenges of geographically distributed teams, and familiarity with construction materials, standards, and methods of foreign countries are vital for modern construction professionals. However, the traditional skills and education style of engineers and construction managers do not equip them to successfully deal with such issues. This paper describes the experiences of a university course International Collaborative Construction Management that was developed to educate the next generation of civil engineers to be more internationally savvy. Throughout the three years that the course has been conducted to date, students in Turkey, the United States, Israel, and Brazil were grouped in multinational teams. They collaborated to develop construction schedules, cost estimates, risk assessment plans and response strategies and to prepare bid documents for actual construction projects. Within the context of this course, students were introduced to the different challenges of cross-cultural collaboration and improved their technical/managerial skills through direct involvement in hands-on experiences.     

Embedded System for Construction Asset Tracking Combining Radio and Ultrasound Signals

Today’s sensor technology provides the increased opportunities for automation and improvement in data acquisition and construction processes. However, many current field practices at construction sites still rely on manual processes for asset tracking and information handling. Previous technologies, such as radio frequency identification and global positioning systems, do not provide a solution to automated asset tracking because of their limitations in terms of applicability and performance in a typical construction environment. This paper introduces a new development of an embedded sensor system for construction asset tracking by combining radio and ultrasound signals. We present the detailed hardware and software architecture and have implemented outdoor experiments to examine the accuracy and performance of the designed system. The results obtained showed the accurate distance and position estimation with enhanced networking flexibility. The findings and lessons learned from this research demonstrate the potential for future practical deployment of similar systems in many civil engineering applications.

Some Ethical Dimensions of Additional Education for the 21st Century

In October of 1998, the ASCE Board of Direction adopted Policy Statement 465 supporting the concept of the master’s degree or equivalent as a prerequisite for licensure and practice of civil engineering at the professional level. Citing globalization, an intricate and complex infrastructure, and new engineering and information technologies, in October of 2001, the board unanimously voted to move forward with a revised Policy Statement 465, entitled “Academic Prerequisites for Licensure and Professional Practice.” This paper examines the ethical dimensions surrounding the call for additional education. To this end, the ASCE Code of Ethics will be discussed as a living document that governs the practice of safe, effective, and professional civil engineering, and will be brought to bear on the issues surrounding the implementation of ASCE Policy Statement 465.
