Construction drawings are communicative language with owner, designer, contractor and also contract documents meaning quantitative and visual description of project. These are valuable as construction knowledge during construction process. Many of design company manage drawings using special drawing management systems because of drawings are made up image based. But, In upload process for drawings, they need effort for input information by designer, that is significant pressure to work. This research uses text information on drawing to efficient upload and search of construction drawings. We develop algorithm for automatically extract text on drawings using metadata library, and drawing management prototype system. Designer can efficient upload drawings to system automatically using drawing management prototype system without extra work.
