This book has been entirely devoted to civil engineers and construction engineers who work in planning. Planning is the most important component of the process of building. The main reason for writing this book is that no one wants to share their knowledge with others anymore, which limits their ability to earn a living. By taking full responsibility for explaining the duties of a planning engineer in this book, I hope to assist any engineer in becoming a better planning engineer. I hope that by doing so, I may assist everyone in improving their work and a better planning engineer.
