Book excerpt: A Design Build project is a type of project delivery mechanism contracted via a single-source with specified construction timeframe and cost. Environmental delay during construction is one of the major reasons why Design Build projects are running behind schedule and over budget. My dissertation assess the environmental delays within the Design Build process carried out by the California High Speed Rail Authority, construction management firms, and Design Build contractors. Currently, the California High Speed Rail Authority has procured three separate Construction Packages comprising of over 120 miles of active rail construction. The Design Build procurement process require evaluation of the individual environmental uncertainties brought upon by the change orders for each of these Construction Packages. Despite the differences in project characteristics, design variations triggered majority of these change orders following the certification of the environmental impact assessment. The change orders can lead to more delays and additional work outside of the approved environmental footprint, subsequent environmental surveys and re-exams, additional land access, Third Party issues, and late planning and poor coordination. To assess the environmental delays caused by the change orders, I propose a mechanism to rank the delay factors which involves development of a typology, assigning delays with a delay score, and preparing a risk register to track all current and emerging change orders by the associated delay scores. The identified environmental delays are then matched to various case scenarios with characteristics that reflect the actual change orders from the Construction Packages. My iterative delay assessments from the Construction Package 4 result in a series of implementation steps for future project delivery. I have synthesized the lessons learned from managing the environmental delays into organizational and project delivery working protocols. I propose to capture these working protocols to reflect the impacts of the proposed recommendations from the current practice. The recommendation can be extrapolated to guide and streamline the environmental assessment and permitting process for future construction and design projects.
Download or read book An Environmental Impact Framework for Evaluating Construction Projects Delays written by Richard Hannis Ansah and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The modern business environment is operating in a highly turbulent time. Demand for operational activities to achieve effectiveness and efficiency, the environment has increased the need for organizational accountability both in private and public sectors. Meanwhile, one noteworthy gap in the management of projects is considering projects as systems existing in isolation from its surrounding environment. From an examination of the deficiencies in such an approach and how to avoid them, an understanding of the concept of the environment is very imperative. Besides, while many variables are said to cause process and system delays in construction projects, most have been conceptualized to assess aspects of project delays. However, most of these variables for assessing project delays still need improvement. This paper presents the concept of project environment, and proposes a comprehensive framework for evaluating delay sources in the external environment of construction projects through 'PESTLE' Framework Analysis namely; Political, Economic, Social, Technological, Legal and Environmental. Following the synthesis and screening of the literature review and the identified main sources, it showed that the major external sources of delays are associated with the 'PESTLE' factors. Thus, it is therefore established that 'PESTLE' framework analysis, if well understood, could be an instrumental tool for project performance assessment studies and contributes to the knowledge and practice on delay control.

This book was released on 2012-12-06 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have undertaken this volume in the belief that there is now sufficient research completed on environmental risk to justify a retrospective assessment of what is known. Our authors and our intended audience are eclectic indeed. Environ mental risk assessment receives increasing attention in the media today. The populace is practically assaulted with stories, with anecdotes, and with conflicting evidence. It is our hope that these chapters will provide the reader with a comprehensive glimpse of a fast-growing field in public policy. No complete survey of the literature would be possible or meaningful. We offer here instead the integrative thoughts of some of the most respected analysts in the field. We believe that the coverage is coherent, the perspectives are illuminating, and the individual "treatments deserving of careful study. We are grateful to Warren Samuels of Michigan State University who is editor of the Kluwer series on recent economic thought. We are also grateful to our Kluwer editor, Zach Rolnik. Both have been gracious in their toleration of unconscionable delays.

Download or read book Comparative Risk Assessment and Environmental Decision Making written by Igor Linkov and published by Springer Science & Business Media. This book was released on 2006-03-02 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision making in environmental projects is typically a complex and confusing process characterized by trade-offs between socio-political, environmental, and economic impacts. Comparative Risk Assessment (CRA) is a methodology applied to facilitate decision making when various activities compete for limited resources. CRA has become an increasingly accepted research tool and has helped to characterize environmental profiles and priorities on the regional and national level. CRA may be considered as part of the more general but as yet quite academic field of multi-criteria decision analysis (MCDA). Considerable research in the area of MCDA has made available methods for applying scientific decision theoretical approaches to multi-criteria problems, but its applications, especially in environmental areas, are still limited. The papers show that the use of comparative risk assessment can provide the scientific basis for environmentally sound and cost-efficient policies, strategies, and solutions to our environmental challenges.
Download or read book Using Risk Analysis for Flood Protection Assessment written by Martina Zeleňáková and published by Springer. This book was released on 2017-02-07 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the benefits of using risk analysis techniques in the evaluation of flood protection structures, and examines the results of the environmental impact assessment for selected planned flood protection projects. The objective of the book is to propose a methodology for environmental impact assessment in water management. In more detail, flood mitigation measures are investigated with the aim of selecting the best option for the approval process. This methodology is intended to streamline the process of environmental impact assessment for structures in the field of the water management. The book’s environmental impact assessment system for water management structures analyzes the respective risks for different options. The results are intended to support the selection of future projects that pose minimum risks to the environment. Comparison of alternatives and designation of the optimal variant are implemented on the basis of selected criteria that objectively describe the characteristics of the planned alternatives and their respective impacts on the environment. The proposed Guideline for environmental impact assessment of flood protection objects employs multi-parametric risk analysis, a method intended to not only enhance the transparency and sensitivity of the evaluation process, but also successfully addresses the requirements of environmental impact assessment systems in the European Union. These modifications are intended to improve the outcomes of the environmental impact assessment, but may also be applied to other infrastructure projects. The case study proves that the primary aim – to improve transparency and minimize subjectivity in the environmental impact assessment process specific to flood protection structure projects – is met for the planned project in Kružlov, Slovakia.

Download or read book Risk Based Environmental Decisions written by Douglas J. Crawford-Brown and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk-Based Environmental Decision: Methods and Culture presents the principles of human health risk analysis as they are applied in environmental decisions. It balances the discussion of scientific theory and methods, philosophical analysis, and applications in regulatory decisions. The material is directed towards risk analysts who must apply their skills in a policy setting, and towards policy analysts who must use risk estimates. The presentation is suited ideally as an introductory text on the methods of risk analysis and on the cultural issues that underlie these methodologies. An important feature of Risk-Based Environmental Decision: Methods and Culture is that it is designed around a series of detailed case studies of environmental risk analysis which walk the reader from the historical nature of the problem, to the formulation as a risk-based problem, to the conduct of risk analysis, and on to the application, debate, and defense of the risk analysis.
Download or read book Global Environmental Risk written by Jeanne X. Kasperson and published by Routledge. This book was released on 2013-05-13 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite international initiatives such as the Earth Summit in 1992 and ongoing efforts to implement the Kyoto Protocol, human activities continue to register a destructive toll on the planetary environment. At root, research on global environmental risk seeks new pathways for reversing unsustainable trends, curtailing ongoing destructive activities, and creating a life-sustaining planet. This book takes stock of the distinctive challenges posed by global environmental risks, the capacity of knowledge systems to identify and characterize such risks, and the competence of human society to manage the unprecedented complexity. Particular attention trains on engaging, in ways conducive to enhancing social learning and adaptation, the large uncertainties inherent in these risks. Various chapters enlist different scales of analysis to explore the manifestation and causes of global environmental risks in all the diversity of their regional expression. Throughout, the editors and contributors accord prominence to the vulnerability of people and places to environmental degradation. Understanding vulnerability is a neglected key to assessing the nature of the risks and determining strategies for altering trajectories of threat. Global risk futures, the editors argue, are not intractable, and are still amenable to a risk-analysis enterprise that is democratic in principle, humanistic in concept, and geared to the realities that pertain to the particular societies, locales, and regions that will ultimately bear the risk.
Download or read book Assessments of Regional and Global Environmental Risks written by Alexander E. Farrell and published by Routledge. This book was released on 2010-09-30 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: As environmental challenges grow larger in scale and implications, it is increasingly important to apply the best scientific knowledge in the decisionmaking process. Editors Farrell and Jäger present environmental assessments as the bridge between the expert knowledge of scientists and engineers on the one hand and decisionmakers on the other. When done well, assessments have a positive impact on public policy, the strategic decisions of private firms, and, ultimately, the quality of life for many people. This book is the result of an international, interdisciplinary research project to analyze past environmental assessments and understand how their design influenced their effectiveness in bringing scientific evidence and insight into the decisionmaking process. The case studies in the book feature a wide range of regional and global risks, including ozone depletion, transboundary air pollution, and climate change. Assessments of Regional and Global Environmental Risks offers several important contributions. It provides a clear account of the choices faced in the design of environmental assessments and a clear description of the lessons learned from past assessments. It illustrates why assessments are social processes, not simply reports. And, while they identify no universal, one-size-fits-all design, the authors find that, to be effective, environmental assessments must be viewed by those who produce and use them as being salient; credible in their scientific support; and legitimate, or fair in design and execution.
