This document discusses how SketchUp can be used for construction project planning and management. It describes how a dynamic component database can be created in SketchUp to represent various construction elements like pipes, valves, concrete, and steel. These components can have attributes and behaviors assigned. The document also discusses how the component database allows collaboration between project stakeholders to assemble a 3D model for preconstruction planning purposes, including generating accurate bills of materials and construction drawings that can be updated automatically when changes are made to the SketchUp model.
