Guidelines For Managing Geotechnical Risks In Design Build Projects

Failing to assess properly can, and sadly still does, cost the construction industry millions of pounds. Much of that could be saved by intelligent use of foresight before the forced excavator even starts work. We certainly have the means, all we need is the will and the professionalism to make it happen. Professor John Burland, FREng, FICE '...the task force wishes to emphasise that we are not inviting UK construction to look at what it does already and do it better: we are asking the industry and government to join with major clients to do it entirely different...' Sir John Egan - Rethinking Construction 1999 Ground related problems and conditions can often adversley affect costs, completion time, profitability, and health and safety issues on a project of any scale. Geotechnical risk can affect all those involved in construction - including the client, designer and the constructor. These guidelines, produced in association with the Department of Environment, Transport and the Regions, provide best practice guidance on the management of geotechnical risk by all parties concerned, and also explain why such risks occur.

This book contains selected articles from the Second International Conference on Geotechnical Engineering-Iraq (ICGE-Iraq) held in Akre/Duhok/Iraq from June 22 to 23, 2021, to discuss the challenges, opportunities, and problems of geotechnical engineering in projects. Also, the conference includes modern applications in structural engineering, materials of construction, construction management, planning and design of structures, and remote sensing and surveying engineering. The ICGE-Iraq organized by the Iraqi Scientific Society of Soil Mechanics and Foundation Engineering (ISSSMFE) in cooperation with Akre Technical Institute / Duhok Polytechnic University, College of Engineering /University of Baghdad, and Civil Engineering Department/University of Technology. The book covers a wide spectrum of themes in civil engineering, including but not limited to sustainability and environmental-friendly applications. The contributing authors are academic and researchers in their respective fields from several countries. This book will provide a valuable resource for practicing engineers and researchers in the field of geotechnical engineering, structural engineering, and construction and management of projects.

Design-Build construction has become so widely accepted that owners and their advisors must seriously consider this approach when making decisions about project delivery. With its opportunities for cost containment and substantial risk transfer, Design-Build is increasingly becoming the delivery method of choice for owners with challenging funding limitations. But deciding to use the Design-Build system for underground projects is one thing; successfully implementing it is quite another. Design-Build Subsurface Projects, Second Edition, can help bridge that gap. First published in 2002, this cutting-edge book provides a straightforward, comprehensive look at how to make Design-Build work on complicated projects involving tunnels, highways, dams, and deep foundations. The authors are a "who's who" of subsurface construction experts, many of whom are key players in the most high-profile and challenging projects in the world. Drawing upon their wealth of practical experience, they spell out a list of common sense best practices that can be used by today's project owners and designers. Be advised: these authors don't shy away from the many thorny issues of Design-Build. Nor are they unabashed cheerleaders. They dispassionately explore both the advantages and disadvantages of this system, which must be carefully weighed and evaluated so planners can decide what is best for their projects based on all the important variables, including third-party impacts and environmental/community concerns. You'll find extensive information about procurement, as well as risk allocation issues, which are significantly different from the Design-Bid-Build approach. Team structure, agreements, design development, subsurface exploration, geotechnical reports, construction phase issues, and insurance are also examined in great detail. Design-Build Subsurface Projects is an indispensable resource for owners, engineers, construction managers, contractors, and others involved in the design and construction of subsurface projects. You'll gain a thorough understanding of how and why the system works and where the pitfalls can arise. The authors' years of experience will benefit even the most seasoned of practitioners.

Risk Management for Geotechnical Engineering: Hazard, Risks and Consequences covers the application of risk management for soil and rock engineering projects, and the preparation of reliable designs that account for uncertainty. The book discusses qualitative risk assessments based on experience and judgement, as well as quantitative risk analysis using probabilistic methods and decision analysis to optimize designs. Many examples are included of how risk management can be applied to geotechnical engineering, with case studies presented for debris flows, rock falls, tunnel stability, and dam foundations. Also discussed are issues of liability insurance and contract law related to geotechnical engineering. This comprehensive book is ideal for practicing geotechnical engineers, addressing the challenges of making decisions in circumstances where uncertainties exist in site conditions, material properties and analysis methods.

Your timely source for more cost-effective and less disruptive solutions to your underground infrastructure needs. The North American Tunneling Conference is the premier biennial tunneling event for North America, bringing together the brightest, most resourceful, and innovative minds in the tunneling industry. It underscores the important role that the industry plays in the development of underground spaces, transportation and conveyance systems, and other forms of sustainable underground infrastructure. With every conference, the number of attendees and breadth of topics grow. The authors—experts and leaders in the industry—share the latest case histories, expertise, lessons learned, and real-world applications from around the globe. Crafted from a collection of 126 papers presented at the conference, this book takes you deep inside the projects. It includes challenging design issues, fresh approaches on performance, future projects, and industry trends as well as ground movement and support, structure analysis, risk and cost management, rock tunnels, caverns and shafts, TBM technology, and water and wastewater conveyance.

This book aims to consolidate, structure and articulate collective knowledge on construction project delivery, procurement and contracting, so that it can serve as a gateway to the contiguous topics of construction project delivery. In addition to supporting the education of student researchers, as well as broadening and deepening the knowledge of practitioners, the book is also intended to serve as a foundation for future education and as a reference book. Academicians can use it to benchmark and support their research and also as a textbook for an undergraduate or graduate course on the topics of project delivery, procurement and contracting.

Model Uncertainties in Foundation Design is unique in the compilation of the largest and the most diverse load test databases to date, covering many foundation types (shallow foundations, spudcans, driven piles, drilled shafts, rock sockets and helical piles) and a wide range of ground conditions (soil to soft rock). All databases with names prefixed by NUS are available upon request. This book presents a comprehensive evaluation of the model factor mean (bias) and coefficient of variation (COV) for ultimate and serviceability limit state based on these databases. These statistics can be used directly for AASHTO LRFD calibration. Besides load test databases, performance databases for other geo-structures and their model factor statistics are provided. Based on this extensive literature survey, a practical three-tier scheme for classifying the model uncertainty of geo-structures according to the model factor mean and COV is proposed. This empirically grounded scheme can underpin the calibration of resistance factors as a function of the degree of understanding – a concept already adopted in the Canadian Highway Bridge Design Code and being considered for the new draft for Eurocode 7 Part 1 (EN 1997-1:202x). The helical pile research in Chapter 7 was recognised by the 2020 ASCE Norman Medal.
