Pioneering Construction Engineering Education

In the 1930's, a small number of educators and contractors began to advocate that colleges and universities develop programs in construction engineering. Through the Great Depression and World War II, they debated what the nature of construction engineering education ought to be. Following World War II, the climate among educators and contractors was receptive to the ideas which the pioneers in construction engineering education had been advocating for 15 yr. Colleges and universities began to offer construction engineering options in their civil engineering curricula.     

Construction Engineering and Management Undergraduate Education

Construction education is not new. It was a part of the practical aspects of many early civil engineering degree programs. As early as the 1920's, specializations in construction engineering were found in a few civil engineering programs, paralleling structural engineering and other areas. However, the gradual need for more specialization than could normally be integrated in the civil engineering degree eventually led to the formation of some construction specialty degree undergraduate programs, particularly after World War II. This paper documents the historical evolution of construction education, promotes construction as a stand-alone professional engineering discipline, provides information for schools that are interested in starting an undergraduate construction engineering and management (CEM) degree program, and discusses the engineering accreditation aspects of the CEM curriculum and the role of the construction industry in the CEM curriculum development.     

VDC and the Engineering Continuum

In this paper, we provide a brief overview of the historical underpinnings of the design-construction industry and the development of design engineering and construction engineering as independent but related subdisciplines of civil engineering. The effects of the first and second generation of computer tools on design engineering are identified. The complementary and evolving definitions of construction engineering and design engineering are examined, specifically in the context of structural design engineering activities and deliverables and the corresponding construction engineering activities and deliverables. The concept of an “engineering continuum” is introduced, and the process is recast in light of that concept. Several case studies are used to examine the promise of third generation design-construction computing technologies such as virtual design and construction and their potential beneficial impact on the cost and schedule of the typical design-construction project. Refinements to the definitions of construction and design engineering that have the potential to maximize the benefits of third generation technology are proposed with an eye toward the form of fourth generation computing technologies that are on the horizon.     

Basic Research Needs in Construction Engineering

The National Science Foundation and the Construction Research Council of the American Society of Civil Engineers sponsored a workshop for leading academic researchers to discuss basic research needs in the construction industry. The workshop, held at The University of Michigan, dealt with issues within five primary categories: (1) Definition of basic research in construction engineering and management; (2) basic research needs in construction engineering management; (3) construction engineering analysis and design; (4) construction engineering uncertainty; and (5) construction engineering human resource management. The participants identified a list of items of a basic nature that require research to develop the theoretical underpinnings of construction practice. A summary of the list of research needs is reported in the paper.     

Linkages between Construction Engineering Education and Research

The needs of the construction industry require that an appropriate balance be provided between construction engineering topics and management topics in both education and research. Because construction is less mature as a research area compared to other areas in civil engineering, limitations on research funding have made the investigation of construction management topics more feasible in comparison to construction engineering topics. Because faculty members are drawn from the pool of Ph.D. students who have primarily researched management topics, there has been a tendency for them to continue emphasis on management topics in both education and research. Other civil engineering disciplines form their research programs around the needs of design codes and standards’ development, and academic participation is high. Similar efforts exist within construction engineering; however, there is less academic participation. It is suggested that greater effort be invested in the improvement of construction process standards and specifications so that construction engineering research efforts can advance construction process standards and stimulate increased engineering educational exposure. It is also suggested that academics who are interested in construction engineering research should consider participating in the specification improvement processes that occur at the national and state levels. A process for wider participation in construction engineering research and standards development is recommended.     

关于公路工程测量监理工作浅论

Emerging Tools to Enable Construction Engineering

Those working within the domain of construction engineering—the planning and management of the construction of infrastructure assets—today employ a wide range of information technology tools. The vast majority of these tools are used on desktop computers processing tabular information associated with scheduling, tracking, updating statuses, reporting, and similar tasks. In spite of the significant penetration of information technology into construction engineering, there is little direct reuse of the engineering information created during the design phase. Likewise, access to rich engineering information and applications to exploit this information have yet to be extended to mobile workers on the construction jobsite in any significant way. This paper explores a sampling of some of the emerging information technology tools that may be effectively applied to support construction engineering in the field.
