Book Description
Construction researchers and industry practitioners have begun to explore the possibilities offered by mobile and pervasive computing in architecture, engineering and construction (AEC). It is expected that the construction industry will be keen to apply these technologies as they promise significant benefits in areas such as materials management, project management, distributed collaboration and information management, all leading to improvements in productivity. This book offers a comprehensive reference volume to the use of mobile and pervasive computing in construction. Based on contributions from a mix of leading researchers and experts from academia and industry, it provides up-to-date insights into current research topics in this field as well as the latest technological advancements and practical examples. The chapters introduce the key theoretical concepts in mobile and pervasive computing and highlight the applications and solutions which are available to the construction industry. More specifically, the book focuses on the manner in which these technologies can be applied to improve practices in construction and related industries. This book will be of particular interest to academics, researchers, and graduate students at universities and industrial practitioners seeking to apply mobile and pervasive computing systems to improve construction industry productivity.

Book Description
To increase the efficiency and reliability of bridge inspections, MDOT contracted to have a 3D-model-based data entry application for mobile tablets developed to aid inspectors in the field. The 3D Bridge App is a mobile software tool designed to facilitate bridge inspection processes by enabling inspectors to enter element-level bridge condition data using 3G/4G network-enabled tablet devices. The system collects information from MDOT's bridge management database, and then renders a dynamic, interactive 3D model of the desired bridge. The bridge inspector is able to record the locations and attributes of new defects in an element-level form by touch interaction and manipulation of the 3D model. The interactive model, marked up with existing defects, also allows for bridge inspectors to better visualize past inspection data. The inspector can also take pictures of the defects using the tablet's camera, as well as record comments. This gives users further insight into the progression of the defect over time. The bridge inspector is able to navigate along the bridge model just as he or she would during a normal inspection. Results can be integrated into bridge management workflows.

Book Description
Bridges are vital elements of the civil infrastructure system in terms of mobility, environment, economy, and development of communities. Maintaining bridges at sufficient functional and safety levels is an important mandate to ministries of transportation. The 2016 Canada infrastructure report card alarmed that more than 26% of bridges in Canada have deteriorated and the bridges are mostly rated as fair, poor or very poor (CIRC 2016). In the United States, the report card on America's infrastructure assigned grade "C+" to bridge infrastructure (ASCE 2017). Hence, developing rational decision support methods that can assist in managing the vast bridge infrastructure is of paramount importance. This research aimed toward developing a decision support methodology for concrete bridges capable for optimizing the Maintenance, Repair and Replacement (MRR) actions under Performance-Based Contracting (PBC) arrangement through implementing the following steps: i) develop an integrated condition assessment and rating model, ii) develop a forecasting model to assess bridge condition reliability and predict future deteriorations/improvements, iii) develop short- and long-term optimized rehabilitation plans, and iv) design a PBC-based framework for rehabilitation decisions. Upon studying bridge inspection standards and current practices, the research introduces the Quality Function Deployment (QFD) theory and Weibull Distribution Function (WDF) to produce novel methods to rate the current bridge conditions and forecast future performance. These methods integrate data extracted from visual inspection and Ground Penetrating Radar (GPR) surveys. The k-means clustering technique is utilized to develop a rating index that recommends suitable MRR actions based on an integrated condition rating. The Genetic Algorithm (GA) optimization technique is applied to select the best combinations of rehabilitation strategies under the PBC scheme. The integrated rating along with the GA optimization ultimately develop a recommended work program that considers the identified performance triggers and budget constraints. The research contributes a novel PBC-based decision support framework to the area of bridge management that enhances efficiency in implementing MRR strategies while maintaining the delicate balance between the different stakeholders' requirements and goals. The developed methodology is implemented and tested on data extracted from bridge inspection reports and GPR scans, mainly on bridges in Quebec, Canada. Ministries of transportation can benefit from the condition rating and deterioration modeling to assess their bridges' condition and to interfere and do a rehabilitation action before reaching the end of useful service life. The GA-based model provides the maintenance contractors with optimized interventions plans that specify what type of MRR actions to do and when. Further, it assists the ministries to set the budget for such projects. The PBC framework is expected to assist both the transportation agencies and maintenance contractors in arriving at a fair contract value while maintaining the desired bridge performance.

Book Description
Maintenance, Safety, Risk, Management and Life-Cycle Performance of Bridges contains lectures and papers presented at the Ninth International Conference on Bridge Maintenance, Safety and Management (IABMAS 2018), held in Melbourne, Australia, 9-13 July 2018. This volume consists of a book of extended abstracts and a USB card containing the full papers of 393 contributions presented at IABMAS 2018, including the T.Y. Lin Lecture, 10 Keynote Lectures, and 382 technical papers from 40 countries. The contributions presented at IABMAS 2018 deal with the state of the art as well as emerging concepts and innovative applications related to the main aspects of bridge maintenance, safety, risk, management and life-cycle performance. Major topics include: new design methods, bridge codes, heavy vehicle and load models, bridge management systems, prediction of future traffic models, service life prediction, residual service life, sustainability and life-cycle assessments, maintenance strategies, bridge diagnostics, health monitoring, non-destructive testing, field testing, safety and serviceability, assessment and evaluation, damage identification, deterioration modelling, repair and retrofitting strategies, bridge reliability, fatigue and corrosion, extreme loads, advanced experimental simulations, and advanced computer simulations, among others. This volume provides both an up-to-date overview of the field of bridge engineering and significant contributions to the process of more rational decision-making on bridge maintenance, safety, risk, management and life-cycle performance of bridges for the purpose of enhancing the welfare of society. The Editors hope that these Proceedings will serve as a valuable reference to all concerned with bridge structure and infrastructure systems, including students, researchers and engineers from all areas of bridge engineering.
