They include any changes made from the initial drawings during the construction process, and provide an exact rendering of the pipeline, valves or other components as it appears upon completion. However, pipelines can be affected  \nby new construction and relocation, because of encroachment.  \nTechnical Toolboxes’ pipeline engineering subject matter expert Joe Pikas was involved in engineering construction back in the 1960s, and like any project, they never went according to the way they were designed for many reasons. These included land issues, right-of-way (ROW) issues and geological issues that affected the ability to put it in the way it was designed due to issues with swamps, etc. Today, pipeline engineers would use horizontal directional drilling to avoid the issues, but back then they could not. As a result, the way the pipeline was drawn on paper did not always work out in real life.  \nThe long-lost era of paper documentation  \nWhen an as-built was carried out, engineers re-surveyed the entire pipeline and all components and determined how they related to the preliminary drawings, as was originally planned. It was at this point that the red lines began. It soon became apparent that maybe the angle of the pipe was supposed to turn 10˚ to the right and it was actually 12˚ ahead and to the left, or it was supposed tobe 10 ft deep and it was actually 5 ft deep. In addition to the main drawings, which were approximately 36 in. long by 18 in. wide, there were also supplemental charts called ROW drawings, which were the size of a regular letter sized piece of paper and had all the crossing locations. The problematic nature of this system of multiple paper drawings was that if a change needed to be marked on the main drawings, it needed to be marked on all of the supplemental drawings too.  \nIn the 1960s, pipeline engineers would carry huge books of reduced size alignment sheets around with them in their vehicles to locate specific components or crossings. Usually an entire seat in their vehicle would be dedicated to transporting these books. However, because the books were not updated as and when changes were made to the pipelines, by the mid-1960s their accuracy left a lot to be desired. It was not unusual for a pipeline engineer to know, anecdotally, that a newer parallel pipeline had been installed near an older, documented pipeline but not to have any record of it in the book. By the late 1960s, the physical distribution from Texas to the Northeast US was a long pipeline system with multiple parallel and lateral systems – most of which were not recorded in the engineers’ sheet book.  \nSpeed over exactitude  \nAs a young pipeliner fresh out of college in 1967, Joe Pikas worked in New Jersey. It was then, as it is now, the most densely populated state in the US at around 1210 people per square mile, which made it more logistically challenging to carry out large diameter (42 in.) pipeline projects. Consequently, it was normal for the large companies overseeing these types of project to be more concerned with getting the pipe into the ground quickly, rather than taking the time to meticulously track the layout of the pipe. As a result of this attitude, the last  \nthing people thought about was these drawings. Back in the 1960s, many pipelines were installed in the US and asthe projects accumulated, so did the drawings. The sense of urgency to get pipelines into the ground as quickly as possible to begin making revenue from them resulted ina lack of attention being paid to the drawings. Partly this was because back then, there were no specific regulations requiring companies to keep accurat","cbCairzMC5ueJwvf","https://ap.wps.com/l/cbCairzMC5ueJwvf","pdf",373847,"English","# As-built drawings and redlines\n## Multiple paper drawings and re-surveying\n## Speed over exactitude and limited regulations\n## GIS adoption and mapping problems","[{\"question\":\"What are as-built redline drawings in pipeline projects?\",\"answer\":\"As-built drawings are revised drawings submitted after pipeline construction, capturing changes made during construction and rendering how pipeline components appear upon completion.\"},{\"question\":\"Why was the paper-based redline system difficult to maintain?\",\"answer\":\"Changes on main drawings often required matching updates across supplemental ROW drawings, and the physical distribution of reduced alignment books made accurate tracking increasingly unreliable.\"},{\"question\":\"How did GIS change pipeline mapping and create problems?\",\"answer\":\"GIS demanded more detailed information than existed in preliminary drawings or as-builts, and mismatches such as station numbers not matching surface measurements and drawings not being to scale became apparent.\"}]","Feb2021.pdf | PDF"]
