![]() ![]() This process was called contact printing, and the result was a blueprint: a white-lined, blue sheet of paper that formed a drawing. As light passed through the translucent top sheet, turning the ferro-gallate sheet beneath it blue (except for where the drawn lines on the top sheet prevented light from passing through to the bottom sheet), the chemical combination would reproduce a complex, finely detailed drawing in minutes. Then, they would expose the paper layering to strong natural light. To create a blueprint, one would first place the translucent paper of an architectural drawing over paper coated with unexposed ferro-gallate. He found that the chemical ferro-gallate, derived from gum, could permanently turn a vivid shade of blue when exposed to strong light. Once construction gets underway, drawings guide the work.Īs physicist John Swain writes for the Boston Globe, blueprints originated after an 1861 discovery by French chemist Alphonse Louis Poitevin. In the pre-construction planning and scheduling phase, contractors use plans to create work breakdowns and schedule construction tasks. Planners estimate building material and labor costs based on plans. Building departments and local governments must review plans before they will issue construction or renovation permits. ![]() By changing perspectives and details, it can do so in a number of ways.Ĭonstruction drawings also fill an important role in the overall construction planning process. Rather, a typical construction plan depicts only one structure and its parts or sections.
