Shop drawings, mark-ups and as-builts are different jobs
Drafting on a project comes in three kinds. Shop drawings turn design drawings into buildable detail for the site or the workshop. Mark-up work takes engineers' and surveyors' redlines and issues revised drawings quickly. As-builts record what was actually built, for handover. Each needs a different pace and a different eye for detail. State which your project needs most, so the operator is matched to it.
