I'm on a facilities project with several above grade tie ins coming up. Each tie in is new to old with a flanged spool piece getting dropped in during the outage. In the weeks leading up to the outage, the Operations group is requesting recurring checks on centerline elevations to ensure they don't run into any issues lining up the spools during the time sensitive shutdown. Is there a quick and dirty way to perform these checks using a level, tape, T square, string, center finder, etc. rather than setting up the level and rod at every spot and shooting elevations? This will occur when the surveyor is on site but I'm just looking for an old fashioned welder's method to have another paper trail of QA/QC documentation.
(The basis for this is historically poor soil conditions at said tie in location)
Thanks, appreciate any feedback.
