What Are As-Builts? A Comprehensive Guide for Construction Professionals What are as-builts? As-builts are accurate, current-state, representations of an existing structure. They serve as critical reference points for engineers, design teams, and project managers, enabling accurate design works and planning for building additions, fitouts, renovations or maintenance. The Evolution of As-Builts: The journey of as-builts has evolved significantly over time. Traditionally, they consisted of 2D drawings created after construction, often based on manual measurements and sketches. With advancements in technology, reality capture methods like laser scanning have revolutionized the process, providing highly detailed, accurate point clouds. Today, the focus has shifted toward digital twins, which are dynamic, real-time virtual replicas of physical assets. This evolution has transformed as-builts from static documents into living, data-driven tools that improve accuracy, efficiency, and ong
