Substation Design Drawing Markups

I have a set of substation electrical schematics that now require clean, accurate mark-ups reflecting our latest design updates. The package includes the site layout plan, single-line diagram, and several detailed wiring diagrams. Your task is to open the native CAD files, layer in the red-line changes I provide, and return fully revised drawings ready for the next engineering review. Please keep every drawing reference, title block, and revision record intact while clearly differentiating new information with the standard markup conventions we already use (colour codes and clouding). I will supply the current PDFs with handwritten notes plus the editable source files; you’ll send back the updated DWGs and matching PDFs. Deliverables: • Updated site layout plan, single-line diagram, and wiring diagrams in native CAD format • Corresponding PDF set sized to original sheet dimensions • Change log summarising every design update applied I will be available for quick clarifications as you work so we can hit the deadline without rework.
