The laboratory was awarded a £1.2 mil project titled "Digitally Enabling the Design for Manufacture, Assembly and Maintenance of Bridges" together with Laing O'Rourke Llc, and Tony Gee and Partners
The consortium of Laing O'Rourke(LOR), Tony Gee and Partners, and the University of Cambridge (Dr Ioannis Brilakis and Prof Campbell Middleton) has been selected for an award of £1,2 mil for Digitally Enabling the Design for Manufacture, Assembly and Maintenance (DfMA) of Bridges by the UK Technology Strategy Board.
This grant is trying to address a major challenge in the infrastructure sector; the supply of bridges is not commoditised in the UK. Bridges are largely designed as bespoke solutions with the majority of the work being carried out on site. Moreover, workers are exposed to hazards since they have to work at elevated heights and spend time near high traffic volumes. When improving and/or replacing existing bridges, disruption through lane closures and detours is common. This project aims to tackle the problems above through an integrated digital delivery process for bridges and bridge parts that will address their whole lifecycle from identification and rationalisation of needs to manufacture, assembly, operation, maintenance and decommissioning. The output will be an interoperable set of digital tools, data schema and virtual prototyping processes that will lead to the automated manufacture of a set of standardised, validated parts and sub-assemblies at a controlled price, configured virtually, and in reality capable of meeting the requirements of the most common bridge types.
This will unlock and leverage the expertise in virtualizing and monitoring infrastructure of the CIT group and the investment made by LOR in Computer Aided Advanced Manufacturing through creation of a demand for offsite manufactured bridge parts and assemblies and allow digitally driven advanced manufacturing processes to be applied to bridge delivery. The project will provide a transformative change in the way we design, build, operate and decommission bridges, accelerate delivery and improve the industry’s safety record by moving significant amount of work off-site.

Dr. Habib Fathi receives the Charles Eastman Top PhD Paper Award at the joint W078 / ICCCBE conference
Habib Fathi, PhD graduate of the CIT Lab, was awarded the Charles Eastman Top PhD Paper Award at the 2014 Computing in Civil and Building Engineering conference. According to the CIB W078 “This award, presented at each of W078's annual international conferences, recognizes the importance of developing top young researchers in the core field of W078, “the application of integrated IT throughout the lifecycle of the design, construction and occupancy of buildings and related facilities”. The award is named after a seminal researcher in this field who has, over his illustrious career, supervised and mentored many of the top researchers found across the world. Chuck Eastman's involvement in W078 dates back to 1988 with a keynote presentation and since then he and his students have been strong supporters of the annual series.”
The paper "Fathi, H. and Brilakis, I. (2014) "A Scale, Rotation, and Affine Invariant Line Detection and Matching Algorithm for 3D Reconstruction of Infrastructure", Proceedings of the 15th International Conference on Computing in Civil and Building Engineering joint with the 2014 CIB W78 Conference on IT in Construction, 23-25 June 2014, Orlando, FL, Pages 942 – 949" sets the foundations for automated reconstruction of civil infrastructure and describes perhaps the most definitive and robust method for detecting 3D lines in civil infrastructure scenes.

Seminar on geometric feature detection in images using a contrario theory
Geometric feature detection in images using a contrario theory
Presenter: Viorica Patraucean
Date: Tuesday 6th of May
Time: 14:40
Location: Sir Arthur Marshall Meeting Room
The main concern in designing geometric feature detectors in images is to obtain reliable results (i.e. reduced number of false detections) on various types of images without any parameter tuning. To achieve this goal, we propose an automatic procedure, having a twofold decision-making role: model validation and model selection. For a given set of pixels in a grayscale image, the detector decides if the set supports a feature (model validation), and identifies its type when multiple interpretations are possible (model selection). We describe discrete and continuous validation and model selection criteria based on the contrario theory.
Brief Biography: Viorica Patraucean completed her Ph.D. in January 2012, and now works as a postdoctoral researcher at INRIA Ecole Polytechnique, Paris. Her research with Pierre Gurdjos (INP Toulouse) and Maks Ovsjanikov (Ecole Polytechnique Paris) focuses on geometric feature detection in images and joint image and 3D shape analysis. Viorica holds an M.S. and Ph.D. degree in Computer Science from INP Toulouse and a B.S. degree in Computer Engineering from Military Technical Academy of Bucharest.

Dr Ioannis Brilakis selected for ASCE 2013 Collingwood Prize
Dr Brilakis, Laing O'Rourke Lecturer of Construction Engineering and his former students, Zhenhua Zhu, Assistant Professor (Concordia University, Canada) and Stephanie German, Post-Doctoral Fellow (EPFL, Switzerland), are the recipients of the 2013 Collingwood Prize of the American Society of Civil Engineers for their paper titled "Visual Pattern Recognition Models for Remote Sensing of Civil Infrastructure", Journal of Computing in Civil Engineering, October, 2011. In selecting this paper for this prize, the committee particularly noted its contribution to engineering knowledge. The award will be presented during the ASCE's Annual Conference Leadership Breakfast, October 11, 2013 in Charlotte, NC.
This paper stemmed out of Dr. Brilakis' CAREER Award from the US National Science Foundation. It outlines his fundamental theory on how to create recognition models for civil infrastructure elements, such as columns, beams, walls, slabs, decks, etc. followed by example applications that have proven successful (see figure, recognized columns in video frames). The paper essentially formalizes 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).
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. 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 modelling process will increase the percentage of infrastructure projects being modelled and, considering that construction is a multi-trillion industry worldwide, each 1% of increase can lead up to billions in savings.
