The document discusses the concept of sustainability in construction. It argues that sustainability is a never-ending journey of continual improvement rather than a destination. It notes that most people lack the skills to understand risk, challenge ideas, and be creative - skills needed for this journey. It compares the journey of sustainability to sailing to a distant island, and emphasizes the importance of understanding one's position and working as a team to avoid dangers and make progress around a virtuous cycle of discovery. The document advocates for an approach of preventing failures through quality assurance and "in process control" rather than post-process inspections, in order to drive process learning and ingenuity toward sustainability.
