The structural and buildable solutions based on experience with similardrawing or sketch is simultaneously the thinking process itself and projects and the unique demands of the project. In some cases,the representation of a solution.the solutions are novel and will require significant development and testing and coordination with the structural engineers design. InWilliam Loganthe best scenario, it is a collaborative solution arrived at in brain-storming sessions with the structural and mechanical engineers and the architects in the room at the same time. It often falls to me to synthesize the solution into a sketch.7'
