This book is composed to assist new and upcoming multi- discipline Project Engineers and Managers in obtaining the basic and necessary knowledge which is required in order to become successful and valuable members of a project team. This book will give an insight to engineering students and professionals on how different engineering disciplines are interrelated in a multi-discipline environment. Together we shall look at Engineering, Procurement and Construction (EPC) projects. EPC projects are very much the norm in the present day engineering contracting industry for capital projects of all types and sizes. Normally, engineers graduate from engineering schools and universities as single discipline engineers. After graduation, they will take up a job based on their particular engineering discipline and then progress in their career. Project Engineers / Engineering Managers combine the different disciplines into a frame work which is often referred to as multi-discipline Project Engineering. Multi-discipline project engineering is a special skill where the engineer has to have basic knowledge of all discipline deliverables. One must know the criticality of the document and how long it should take to get reviewed / commented by other discipline. Multi-discipline project engineers should have understanding of Quality, be cost consciousness and have an understanding of how deliverables effects scheduling. It is an added bonus if one has knowledge of risk management In this book, we are not going to discuss any engineering calculation details. Main focus of this book is to highlight requirements of multi-discipline co-ordination and to show some examples. Major deliverables of different disciplines are mentioned in respective chapters to give project engineers an idea of what these deliverables look like and how are they inter-related.
