Surface and Underground Excavations – Methods, Techniques and Equipment (2nd edition) covers the latest technologies and developments in the excavation arena at any locale: surface or underground.
In the first few chapters, unit operations are discussed and subsequently, excavation techniques are described for various operations: tunnelling, drifting, raising, sinking, stoping, quarrying, surface mining, liquidation and mass blasting as well as construction of large subsurface excavations such as caverns and underground chambers. The design, planning and development of excavations are treated in a separate chapter. Especially featured are methodologies to select stoping methods through incremental analysis.
Furthermore, this edition encompasses comprehensive sections on mining at ‘ultra depths’, mining difficult deposits using non-conventional technologies, mineral inventory evaluation (ore – reserves estimation) and mine closure. Concerns over Occupational Health and Safety (OHS), environment and loss prevention, and sustainable development are also addressed in advocating a solution to succeed within a scenario of global competition and recession.
This expanded second edition has been wholly revised, brought fully up-to-date and includes (wherever feasible) the latest trends and best practices, case studies, global surveys and toolkits as well as questions at the end of each chapter. This volume will now be even more appealing to students in earth sciences, geology, and in civil, mining and construction engineering, to practicing engineers and professionals in these disciplines as well as to all with a general or professional interest in surface and underground excavations.

A comprehensive resource that builds a bridge between engineering disciplines and the building sciences and trades, Forensic Engineering: Damage Assessments for Residential and Commercial Structures provides an extensive look into the world of forensic engineering. With a focus on investigations associated with insurance industry claims, the book describes methodologies for performing insurance-related investigations including the causation and origin of damage to residential and commercial structures and/or unhealthy interior environments and adverse effects on the occupants of these structures.
Edited by an industry expert with more than 30 years of experience, and authors with more than 100 years of experience in the field, the book takes the technical aspects of engineering and scientific principles and applies them to real-world issues in a non-technical manner. It provides readers with the experiences, investigation methodologies, and investigation protocols used in, and derived from completing thousands of forensic engineering investigations. It begins with providing a baseline methodology for completing forensic investigations and closes with advice on testifying as an expert witness.
Much of what must be known in this field is not learned in school, but is based upon experience since recognizing the cause of a building system failure requires a blending of skills from the white collar and blue collar worlds. Such knowledge can be vital since failures (e.g., water entry) often result from construction activities completed out of sequence.. This book details proven methodologies based on over 7,000 field investigations, methodologies which can be followed by both professionals and laymen alike.

Geotechnical Aspects of Underground Construction in Soft Ground comprises a collection of 118 papers, four reports on symposium themes, and four invited lectures presented at the seventh International Symposium on Geotechnical Aspects of Underground Construction in Soft Ground, held in Rome, Italy, 16-18 May 2011.
The symposium was organized by the Technical Committee TC28 “Underground Construction in Soft Ground” of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). This is the latest in a series which began in New Delhi in 1994, and was followed by symposia in London (1996), Tokyo (1999), Toulouse (2002), Amsterdam (2005), and Shanghai (2008). The Rome symposium was organised by the Italian Geotechnical Society (AGI), under the auspices of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) and the Italian Ministry for Public Works, and sponsored by various national and international companies.
Geotechnical Aspects of Underground Construction in Soft Ground includes contributions from 30 countries on research, design and construction of underground works in soft ground. The contributions cover:
- Construction, design, and measured performance of bored tunnels
- Physical and numerical modelling of deep excavations and bored tunnels
- Construction, design, and measured performance of deep excavations
- Design methods and predictive tools for deep excavations and bored tunnels
- Ground movements, interaction with existing structures and mitigation measures
- Activities of TC204 working groups
The general reports give an overview of the papers listed in the symposium’s technical sessions. The proceedings include the written version of the four invited lectures covering topics ranging from the geotechnical aspects of construction of the new Mexico City deep sewerage system (as a special contribution of TC214 “Soft Soils”), to the long-term settlement mechanisms of tunnels in Shanghai, the lessons learned from the deep excavations for the North-South Line in Amsterdam, and the evaluation of the effects of tunnel excavation on historical buildings, drawing on experience gathered during construction of subway line C in Rome.
Similar to previous editions, Geotechnical Aspects of Underground Construction in Soft Ground represents a valuable source of reference on the current practice of analysis, design, and construction of tunnels and deep excavations in soft ground. The book is particular aimed at academics and professionals interested in geotechnical and underground engineering.

A critical aspect of sustainability associated with water and wastewater systems is to maintain and manage infrastructure in the most efficient and economical manner while complying with environmental regulations and keeping rates at acceptable levels.
Given the high cost of fuel, our growing population, and the associated increase in energy needs, it is important to address energy use and future energy availability for the treatment of the water we drink and the water we pollute. Water & Wastewater Infrastructure: Energy Efficiency and Sustainability addresses these issues, detailing the processes that can assist facilities to become more energy efficient and providing guidance to ensure their sustainability.
The text begins with brief descriptions of the water and wastewater treatment industries. It then describes some of the basics of energy and discusses what planning for a sustainable energy future in water and wastewater treatment plants entails. The author explores energy-saving options and provides case studies to demonstrate how some facilities have used equipment, technology, and operating strategies to save money and reduce their impact. The energy-efficient technologies include combined heat and power (CHP), gas turbines, microturbines, reciprocating engines, steam turbines, and fuel cells. The author also addresses biomass power and biogas.
The section on sustainability and renewable energy covers hydropower, solar power, and wind power as well as energy conservation measures for treating wastewater. Nine appendices provide individual case studies that present evaluations of energy conservation measures, results, payback analysis, and conclusions. This book addresses the challenges faced by water and wastewater treatment facilities by examining how they can operate in ways that provide economic and environmental benefits, save money, reduce environmental impact, and lead to sustainability.

I have query regarding the piracy of the softwares.
my question to all is
DOES THE PIRATED SOFTWARES GIVE BAD RESULTS FOR THE CALCULATIONS / SIMULATIONS? I MEAN CAN ONE BE DEPENDENT ON THE RESULTS GIVEN BY A PIRATED SOFTWARE?
To my understanding I personally feel that the fully unlocked/pirated software will perform as good as a genuine software. However, it can happen that some modules in the cracked softwares may be locked but those modules which are unlocked will be performing perfectly.
I would like sum pros to throw sum light on this topic.

The construction industry is the largest single waste producing industry in the UK. Ensuring a supply chain of recycled materials affords many potential gains, achieved through: reducing the material volume transported to already over-burdened landfill sites, possible cost reductions to the contractor/client when considering the landfill tax saved and the potential for lower cost material replacements, a reduction in the environmental impact of quarrying and the saving of depleting natural material resources.
Reuse of Materials and Byproducts in Construction: Waste Minimization and Recycling addresses use of waste and by products in the construction industry. An over view of new “green” design guides to encourage best practice will be examined and current legislation that channels on site practices, such as site waste management plans. Fundamental individual construction materials are discussed and the process of reforming by products and waste products into new construction materials is investigated, examining the material performance, energy required to convert waste into new products and viability of recycling. The main range of constructional materials will be examined.
Aimed at postgraduate students, lecturers and researchers in construction and civil engineering, the book will also be of interest to professional design practices.
