WHY CONSTRUCTION PROJECTS GO WRONG TECHNICALLY Even When Drawings Look Complete Why do technically complete construction projects still fail? Even when drawings are issued for construction. Even when coordination meetings are done. Even when approvals are signed. This book examines a recurring problem across construction and infrastructure projects: the gap between documented completeness and execution reality. Based on observations across oil & gas, mining, and construction environments, this work explores how technical confidence is often built on assumptions that are not fully visible—and not fully validated—before construction begins. Rather than focusing on execution errors or individual mistakes, the book presents a structural perspective on why technically competent projects encounter predictable issues. It analyzes how design assumptions, coordination processes, and approval systems interact with field conditions, and why these interactions can lead to misalignment during execution. Topics include: • The limitations of “Issued for Construction” (IFC) drawings • Why coordination does not guarantee alignment • The hidden role of subsurface and ground uncertainty • Interface risks between disciplines and systems • The gap between analytical design and physical constructability • How documentation can increase confidence without increasing control This is not a construction manual or a project management guide. It is a technical examination of how assumptions behave when exposed to real conditions—and why that behavior matters for engineers, project teams, and decision-makers. Written for professionals in engineering, construction, oil & gas, mining, and infrastructure development, this book offers a framework for understanding problems that are often recognized in hindsight—but rarely explained in advance.
