From Real to Virtual: Reconstructing and Recognizing the Built Infrastructure for Automating Construction, Assessment and Maintenance
According to the UK Royal Academy of Engineering and the US National Academy of Engineering, mapping our existing infrastructure and its condition inexpensively, and automating construction through computer science and robotics advancements are two of the engineering grand challenges for this century. This seminar outlines a series of research projects that help address these challenges based on a common computer vision framework; a general approach to creating visual pattern recognition models that automate the recognition of infrastructure objects based on their visual and spatial characteristics. The projects presented create such models to a) measure the size of objects, such as dimensions of roof panels, for as-built geometric modeling and quantity take-offs, b) count objects, such as bricks, workers, and trucks, for comparing the as-built with the design and measuring sustainability and productivity, c) spatially track materials, personnel, vehicles and equipment to automate project and congestion monitoring and control systems, and d) detect defects/damage on objects, such as cracks, spalling, air pockets, and potholes, for structural damage assessment and maintenance decision making.

April 16, 2012
Georgia Tech and the School of Civil and Environmental Engineering made an impressive showing at the 2012 Fiatech Technology Conference & Showcase, an annual event recognizing achievements in the engineering and technology fields. This year's three-day event was held at the Marriott Doral Golf Resort and Spa in Miami, Florida on April 2-4, 2012.
Fiatech is an international community of global leadership organizations focused on innovation in the capital projects industry. The organization's Celebration of Engineering & Technology Innovation (CETI) Awards recognize significant achievements in technology research, development, and implementation. Established in 2006, the CETIs recognize both organizations and individuals: organizations for successfully implementing new and emerging technologies, and individuals for making significant strides in advancing innovation in research and development.
The 2011 CETI recipients included 11 honorees in nine categories. Three of this year's honorees represented Georgia Tech. They include:
Outstanding Early Career Researcher
Dr. Ioannis Brilakis: Dr. Brilakis teaches at Georgia Tech and is known for his groundbreaking research in infrastructure object recognition and reconstruction. The National Science Foundation recently awarded Brilakis a grant for research that may revolutionize the way infrastructure is mapped. Beyond research, however, Brilakis is known for advancing academia, developing curricula, and mentoring rising stars in the engineering and construction industry. In education, Brilakis has focused on creating research-based interdisciplinary courses and providing elementary, high school, and college students with the opportunity to engage in research.
Outstanding Student Research Project
Man-Woo Park: Georgia Tech Civil and Environmental Engineering Ph.D. candidate Man-Woo Park has made notable strides in the promising technique of vision tracking. Two or more cameras and a processor are the only equipment required. Each camera view is continuously searched for workers, equipment, and materials. Once a resource is detected, its image is represented by a 2D vision. Detection is possible by characterizing visual patterns and then matching those visual patterns. This fully automated on-site monitoring technique can track a large number of entities, covers a vast area, and is fast and economical.
Intelligent and Automated Construction Job Site
Georgia Tech & Metalforming's Rapid, On-Site Digital Fabrication of Sheet Metal Roof Panels: Researchers from Georgia Tech and Metalforming invented a technology that automates the entire on-site sheet metal fabrication process. Recent advances in machine vision algorithms and high-res video cameras allowed researchers to develop a roof surveying technology. The captured video data, stored on a laptop, provided a 3D wire diagram of the roof. Detailed dimensions allowed a download of that data to a USB flash drive, where it was used to automatically roll, form, and cut the roof panels.
Lisa Grayson, chair of the jury and project department program advisor for ExxonMobil, was impressed with all of the entries. "It's clear that the pace of technological innovation in the capital projects industry is gaining momentum. Fiatech serves both as a catalyst for new ideas and a platform for recognizing those whose achievements are outstanding" she said.
Awards jury member Jim Purvis, group director of engineering systems for WorleyParsons, also stressed innovation. "In a global industry like capital projects, innovation helps us use fewer resources while delivering the expectations of our clients" he said.
Jim Newman of AREVA, also a jury member, echoed Purvis' assessment. "The real-time ability in the field to see changes and next steps is vital to perform on time and budget. Those honored tonight prove that innovation can be deployed on real projects, not just on prototype applications" he said.
In addition to Grayson, Purvis, and Newman, the jury for the CETI awards consisted of John Fish, Ford, Bacon & Davis; Raju Hingorani, Jacobs Engineering; Harold Monk, Autodesk; Tom Sawyer, ENR; and Dr. Jochen Teizer, Georgia Institute of Technology.
Congratulations to Dr. Brilakis, Man-Woo Park, and the entire research team!

Ioannis Brilakis Wins NSF CAREER Award
May 4, 2010
Ioannis Brilakis, assistant professor in Civil and Environmental Engineering and Building Construction, has received a CAREER Award from the National Science Foundation (NSF) for his project, "CAREER: Visual Pattern Recognition Models for Remote Sensing of Civil Infrastructure" The five-year award at $402,279.00 will continue Brilakis' work in model based infrastructure elements recognition, an area in which he's been involved since 2005. He has applied machine vision algorithms to study ways to detect patterns in infrastructure data, such as structural elements, damage, defects, construction equipment and workers, so as to allow the use of low cost cameras for construction automation and infrastructure mapping. The project that won him the CAREER Award will involve formalizing the process of creating new Visual Pattern Recognition (VPR) models to simplify the steps needed to create each mathematical description and provide a set of common tools necessary for this purpose. This will automate the transformation of infrastructures, 3D surfaces into information rich, 3D element models with the help of machine vision. Brilakis said that this way, instead of manually recognizing each element every time it is encountered, we need only recognize its characteristics once and automatically detect it each subsequent time. This is analogous to defining an alphabet (letters = characteristics) so that this project will build the words (element models) and find them in a text (3D surface), instead of having to manually find the words in every text we encounter. The benefit comes from the ability to reuse the known letters (characteristics) and words (element models) every time we have a new text (3D surface). As an educational component, he said the project's validation prototype will be created and used also for educational purposes at all education levels (K-12, undergraduate, graduate). "I have partnered with the SEIMC GIFT Program, the ACE Atlanta Mentor Program and others to bring the VPR model prototype in K-12 education, and excite the high school students' interest in science and math through cool machine vision innovations," Brilakis said. "Undergraduate students will get hands-on experience in courses through a concrete and steel inspector spin-off, and graduate students will actually help create new VPR models and validate them as part of course semester projects." "The immediate advantage that will result from this work is the ability to automate the element recognition step of the "as-built" model generation process," Brilakis said. The National Academy of Engineering recently listed "Restoring and Improving Urban Infrastructure" as one of the Grand Challenges of Engineering in the 21st century. Two of the greatest issues that cause this grand challenge are the need for more automation in construction, through advances in computer science and robotics, and the lack of viable methods to map and label existing infrastructure. Over two thirds of the effort needed to model even simple infrastructure is spent on manually converting surface data to a 3D model. The result is that as-built models are not produced for the vast majority of new construction and retrofit projects, which leads to rework and design changes that cost up to 10% of the installed costs. Any efforts towards automating the modeling process will increase the percentage of infrastructure projects being modeled and, considering that construction is a $900 billion industry, each 1% of increase can lead up to $900 million in savings."
