In recent years, industrial development in Taiwan has mostly focused on heavy industry and technology. Due to industrial facility requirements, many medium-to-large industries had to install various underground pipelines in their factories. The work quality and later maintenance of these pipelines have an impact on factory operations. If there is no proper drawing operation management mechanism, a lot of time and money will be wasted in solving the interference problem between engineering interfaces. This research is mainly intended for underground pipelines in large industrial factory zones. Applying the grid drawing concept as a starter and with the integrated definition function modeling (IDEF0) system analysis, we will establish a work flow and apply it in the real world. By using AutoCAD plotting software as a tool, we will also integrate and plot underground engineering drawings (water, electricity, foundation, road, etc) into a single large drawing for ease-of-use in planning, design and construction. It can also be used for reference by maintenance and renovation units after project completion. This research will be discussed, analyzed and fed back from real cases to achieve research objectives.
