This book reports from the leading edge of the world’s biggest infrastructure construction projects. Megaprojects, with costs of more than US $1 billion, are being surpassed by gigaprojects with price tags higher than US $10 billion. These enormous projects are critical to meeting the growing demands of global populations, yet they present daunting obstacles for effective planning, design, construction, and delivery. Not only do the challenges of a megaproject increase exponentially with its size, but these projects can span long time frames. Risk management alone poses unprecedented problems of scale and complexity. The editors have assembled a stellar group of financiers, owners, program managers, consultants, designers, contractors, and legal counsel, all of whom have frontline experience with megaprojects and gigaprojects. In the first part, these experts share lessons learned and best practices developed as they grappled with specific difficulties posed such large-scale projects. In the second part, construction professionals describe megaprojects undertaken in the Middle East, Brazil, Asia, Australia, Europe, and North America with a view to highlighting strategies that lead to success. Engineers, construction managers, planners, and risk managers will find in this volume useful tools for the effective and efficient execution of megaprojects and gigaprojects. This book is also an indispensable guide for investors, senior executives, board members, and other participants involved in these large-scale projects.

> Latest research results in order to incorporate the lifetime of materials into the concept of buildings
> Emphasis on concrete and steel constructions
Safety and reliability are important for the whole expected service duration of an engineering structure. Therefore, prognostical solutions for different building types are needed and uncertainties have to be handled. Life-cycle strategies to control future structural degradations by concepts of appropriate design have to be developed, in case including means of inspection, maintenance, and repair. Aspects of costs and sustainability also matter.
The Cooperative Research Center for Lifetime-Oriented Design Concepts (SFB 398) at Ruhr University in Bochum combines the wide range of scientific topics between structural engineering, structural and soil mechanics and material sciences regarding structural lifetime management in this present extraordinary monolithic format.
The characterization and modeling of lifetime-related external actions of multiple origin are presented in this book as well as the physical description, the modeling and the validation of material degradation. Adaptive numerical methods and simulation techniques are provided for the lifetime-oriented design concepts to forecast material and structural degradation. Stochastic aspects, mathematical optimization methods and interactions between various influences are included. Thus, a solid basis is provided for future practical use and also for standardization of structural design with respect to lifetime-prediction.

Health Assessment of Engineered Structures has become one of the most active research areas and has attracted multi-disciplinary interest. Since available financial recourses are very limited, extending the lifespan of existing bridges, buildings and other infrastructures has become a major challenge to the engineering profession world-wide. Some of its related areas are only in their development phase. As the study of structural health assessment matures, more new areas are being identified to complement the concept.
This book covers some of the most recent developments (theoretical and experimental) and application potentials in structural health assessment. It is designed to present currently available information in an organised form to interested parties who are not experts in the subject.
Each chapter is authored by the most active scholar(s) in the area. After discussing the general concept, various currently available methods of structural health assessment (such as the use of smart sensors) are presented. Health Assessment discusses the following: sensor types, platforms and data conditioning for practical applications; wireless collection of sensor data, sensor power needs and on-site energy harvesting; and long term monitoring of structures. Uncertainty in collected data is also extensively addressed. A chapter discussing future directions in structural health assessment is also included.

Author: Peter C. Taylor | Size: 12.8 MB | Format:PDF | Quality:Original preprint | Publisher: CRC Press | Year: 2013 | pages: 214 | ISBN: 9780203866139
Features
Explains the benefits of curing on concrete performance
Offers guidance on how to select and apply a curing method
Discusses how to specify and measure curing in a project
Includes examples evaluating the use of curing in real-world structures
Discusses U.S. and European Standard specifications, making the book applicable for international use
Contains more than 80 illustrations and photographs
Summary
Curing is one of those activities that every civil engineer and construction worker has heard of, but in reality does not worry about much. In practice, curing is often low on the list of priorities on the construction site, particularly when budgets and timelines are under pressure. Yet the increasing demands being placed on concrete mixtures also mean that they are less forgiving than in the past. Therefore, any activity that will help improve hydration and so performance, while reducing the risk of cracking, is becoming more important. Curing Concrete explains exactly why curing is so important and shows you how to best do it.
The book covers:
The fundamentals behind hydration
How curing affects the properties of concrete, improving its long-term performance
What curing technologies and techniques you can use for different applications
How to effectively specify, provide, and measure curing in a project
The author also gives numerous examples of how curing—or a lack of it—has affected concrete performance in real-world situations. These include examples from hot and cold climates, as well as examples related to high-performance concrete, performance parameters, and specifications and testing. Written for construction professionals who want to ensure the quality and longevity of their concrete structures, this book demonstrates that curing is well worth the effort and cost.
