Preface

In engineering, risk management is the first step to developing economical and safe solutions. Risk management is a fundamental concept in construction to realize the optimal project. In technical terms, risk is defined as the measure of the probability and severity of adverse effects on life, health, property, or the environment. Researchers consider the fact that risk is estimated by the combined impact of the scenario, probability of occurrence, and the associated consequence. In some cases, the term "risk" focuses on economic concerns, while at other times it refers to loss of life.

Risk management is the systematic process of analyzing, identifying, and responding to project risks. It mainly consists of maximizing the chances and the impact of positive events. It also helps to minimize the probability and the impact of negative events. In addition, it aims to meet the project's objectives. In other words, risk management can be considered a decision-making process, involving a full understanding of known risks and/or necessary actions to reduce the effects and chances of such risks. In the construction industry, risk management studies begin with risk identification, continue with risk analysis and evaluation, and finalize with risk response. In summary, construction risk management is the process of evaluating and implementing procedures to reduce the impact of risks in construction projects.

In this book, researchers and engineers have authored chapters focused on the latest advances in construction risk management. The book includes both theoretical and practical papers of high technical standards for various aspects of risk management, thus facilitating an awareness of modern techniques and methods. We selected high-quality submissions of original research as well as review articles that have the potential for practical application.

Chapter 1 presents a study on the risk management of large dams in the operation stage using actual projects in Türkiye. Chapter 2 presents a building damage estimation and renovation proposal system using constant microtremor measurement for construction risk management. Chapter 3 deals with recent advancements in the management of construction risks. Chapter 4 discusses managing uncertainty in the construction phase of road projects. Chapter 5 focuses on the risk factors affecting public infrastructure projects. Chapters 6 and 7 contain studies on approaches to improving occupational health and safety of the Nigerian construction industry and the risk of delay in construction projects, respectively. Finally, Chapter 8 introduces a study done on client type and communication practice during the pre-contract phase of construction project development in Nigeria.

It is our hope that this book proves a useful resource for readers studying risk management in engineering, as it introduces recent scientific research and the latest knowledge of the construction industry. We are thankful to the authors for their excellent contributions.
