Systematic progress monitoring through rigorous identification, processing, and visualization of progress discrepancies between as-planned and as-built performances, is a necessity for successful project management. It provides an early warning to project managers and allows them to diagnose performance problems and to take corrective actions in a timely manner to reduce the impacts of progress discrepancies. However, systematic implementation of progress monitoring has significant challenges because: 1) Current practice is time-consuming since it needs extensive as-planned and as-built data extraction; 2) Quality of the manually collected data maybe low and subjective; 3) Existing methods are also non-systematic, so there is always a tendency to let project inputs serve as surrogate measures for performance outputs which affects the quality of the results; 4) Reports can be visually complex and thus not effectively represent multivariable progress information (i.e., schedule, cost, and performance) in a holistic manner nor intuitively reflect information pertaining to spatial aspects of the construction progress and their associated complexities; 5) Furthermore, current reporting methods increase the time required to describe and explain progress situation in coordination meetings and in turn could delay decision making. Thus, with current mechanism, it may be not be easy to understand the progress situation clearly and quickly.

This presentation will therefore focus on addressing these challenges through an interactive ubiquitous visualization of construction progress monitoring using 4 Dimensional Augmented Reality (D4AR) models In the proposed research, progress deviations (e.g., schedule, cost and performance) would be visualized through superimposition of 4D as-planned models onto site photographs using different visualization techniques such as traffic light and weather metaphors, fish eye, and x-ray.

Feniosky Peña-Mora is an Associate Provost Fellow, O’Neil Faculty Scholar, and Professor in the Department of Civil and Environmental Engineering as well as a Center Affiliate at the National Center for Supercomputing Applications at the University of Illinois. Professor Peña-Mora earned a Master of Science (M.S.) degree in Civil Engineering and a Doctor of Science (Sc.D) in Civil Engineering Systems from MIT in 1991 and 1994, respectively. Before coming to the University of Illinois in 2003, Professor Peña-Mora worked at MIT as Assistant Professor and Associate Professor of information technology and project management in the Civil and Environmental Engineering Department.

Professor Peña-Mora’s research interests include information technology support for collaboration in preparedness, response, and recovery during disasters involving critical physical infrastructures. He is also involved in change management, conflict resolution, and processes integration during the design and development of large-scale civil engineering systems.  His research has been ground breaking in the field of construction engineering and management.

Professor Peña-Mora is the author of more than one-hundred publications in refereed journals, conference proceedings, book chapters, and textbooks on computer-supported design, computer-supported engineering design and construction, as well as project control and management of large-scale engineering systems. His publication, “Design Rationale for Computer Supported Conflict Mitigation,” received the 1995 award for best paper published in the American Society Civil Engineers’ (ASCE) Journal of Computing in Civil Engineering. He is also the author of Introduction to construction dispute resolution (2002), an influential textbook in the field of Construction Conflict Resolution.  His research work has also resulted in three patents and two patents that are pending.

Furthermore, Professor Peña-Mora is the holder of the 1999 National Science Foundation CAREER Award and the 2000 White House Presidential Early Career Award for Scientists and Engineers (PECASE) Award. More recently, he has won the 2007 ASCE Walter L. Huber Civil Engineering Research Prize. He has served as an Associate Editor for the ASCE Journal of Computing in Civil Engineering and editorial board member of the IEEE Internet Computing Magazine. He is currently a Specialty Editor for the ASCE Journal of Construction Engineering and Management and editorial board member of Automation in Construction, the Journal of IT in Construction and the Revista Ingeniería de Construcción.   He has been invited to give keynote and plenary speeches at numerous conferences and symposiums, including the 2001 National Academy of Engineering Frontiers of Engineering Symposia, the 2003 American Society of Civil Engineers Symposium on Information Technology in Civil Engineering, and the 2004 National Academies Convocation on Facilitating Interdisciplinary Research.
